Migrating from v7 to v8

The following sections go over all necessary changes. They also give recommendations on how to structure your PRs and commits.

warning

Many changes can be handled by upgrade scripts. Use them!

The 🤖 emoji marks changes that can be handled by an upgrade script. You just have to execute the script. Below the command there usually is a details drawer that describes the changes made.

Prerequisites

There are some steps that are necessary for the COMET v8 update but can be done beforehand:

Step 1: Upgrade node to v22 (PR #1)

info

You can skip this step if your project already uses node v22

Create a branch node-22. Then make the following changes:

🤖 In development:

Execute the following upgrade script:

npx @comet/upgrade@latest v8/replace-node-with-v22-locally.ts

Details

- 20
+ 22

- "@types/node": "^20.0.0",
+ "@types/node": "^22.0.0",

🤖 In pipeline and deployment:

Execute the following upgrade script:

npx @comet/upgrade@latest v8/replace-node-with-v22-in-gitlab-ci-files.ts

Details

Make sure you use Node 22 in your CI files. When using Gitlab CI, check all files in the .gitlab-ci folders. Make sure to extend the correct jobs and replace all images and base images.

- extends: .lint-npm-node20
+ extends: .lint-npm-node22

- BASE_IMAGE: "ubi/s2i-ubi9-nodejs20-minimal"
+ BASE_IMAGE: "ubi/s2i-ubi9-nodejs22-minimal"

- image: eu.gcr.io/vivid-planet/utils/ubi9-nodejs20-minimal:master
+ image: eu.gcr.io/vivid-planet/utils/ubi9-nodejs22-minimal:master

Now open a PR from node-22 to main

Step 2: Update Typescript to v5 (PR #2)

info

You can skip this step if your project already uses typescript v5 everywhere

Create a branch typescript-5.

Make the following changes:

package.json
-        "typescript": "^4.2.3",
+        "typescript": "^5.9.3",

api/package.json
-        "typescript": "^4.2.3",
+        "typescript": "^5.9.3",

admin/package.json
-        "typescript": "^4.2.3",
+        "typescript": "^5.9.3",

site/package.json
-        "typescript": "^4.2.3",
+        "typescript": "^5.9.3",

Execute npm install in each folder (/api, /admin, /site, /)

Check carefully for errors during the install. Errors might occur because of other packages that depend on typescript v4. Update such packages to make the errors disappear.

Execute npm run lint in the root directory.

Fix occurring errors.

You might also see a warning like this:

=============

WARNING: You are currently running a version of TypeScript which is not officially supported by @typescript-eslint/typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=3.3.1 <5.2.0

YOUR TYPESCRIPT VERSION: 5.9.3

Please only submit bug reports when using the officially supported version.

=============

Ignore this warning for now.

Check if the app still starts

Now open a PR from typescript-5 to main

Step 3: Switch from `@comet/cms-site` to `@comet/site-nextjs` (PR #3)

info

You can skip this step if your project doesn't have a site

warning

This doesn't work if you use other packages that depend on @comet/cms-site. In that case, skip this step for now and do it later during the v8 update.

The @comet/cms-site package has been reworked and renamed to @comet/site-nextjs. Notable changes are

Styled components is no longer a required peer dependency
Instead, SCSS modules are used internally
The package is now pure ESM

To switch you must

Create a branch switch-to-site-nextjs
cd site
npm uninstall @comet/cms-site
npm install @comet/site-nextjs@7
Change all imports from @comet/cms-site to @comet/site-nextjs (with search and replace in your IDE)
Import the css file exported by the package:
site/src/app/layout.tsx
```
+ import "@comet/site-nextjs/css";
```

Switch the package in optimizePackageImports:

site/next.config.mjs
const nextConfig = {
    // ...
    experimental: {
        instrumentationHook: true,
-       optimizePackageImports: ["@comet/cms-site"],
+       optimizePackageImports: ["@comet/site-nextjs"],
    },
    // ...
}

Now open a PR from switch-to-site-nextjs to main

Step 4: Update eslint and prettier (PR #4)

Create a branch update-eslint-to-v9

🤖 Upgrade ESLint from v8 to v9 with ESM

Execute the following upgrade script:

npx @comet/upgrade@latest v8/eslint-dev-dependencies.ts

Handled by @comet/upgrade

Update ESLint to v9

package.json

- "eslint": "^8.0.0",
+ "eslint": "^9.0.0",

An ESM compatible ESLint config is required. Delete the related .eslintrc.json and move the configured rules to the new ESLint flat configuration eslint.config.mjs.

Migration Guide of ESLint 9.0 can be found here: Migration Guide

`admin/eslint.config.mjs`

import cometConfig from "@comet/eslint-config/react.js";

/** @type {import('eslint')} */
const config = [
    {
        ignores: ["schema.json", "src/fragmentTypes.json", "dist/**", "src/**/*.generated.ts"],
    },
    ...cometConfig
];

export default config;

`api/eslint.config.mjs`

import cometConfig from "@comet/eslint-config/react.js";

/** @type {import('eslint')} */
import cometConfig from "@comet/eslint-config/nestjs.js";

/** @type {import('eslint')} */
const config = [
    {
        ignores: ["src/db/migrations/**", "dist/**", "src/**/*.generated.ts"],
    },
    ...cometConfig,
];

export default config;

`site/eslint.config.mjs`

import cometConfig from "@comet/eslint-config/react.js";

/** @type {import('eslint')} */
import cometConfig from "@comet/eslint-config/nextjs.js";

/** @type {import('eslint')} */
const config = [
    {
        ignores: ["**/**/*.generated.ts", "dist/**", "lang/**", "lang-compiled/**", "lang-extracted/**", ".next/**", "public/**"],
    },
    ...cometConfig,
];

export default config;

After executing the script, create a commit with --no-verify.

Migrate custom eslint rules

warning

The upgrade script only creates a simple version of the new eslint.config.mjs. It adds the old config from .eslintrc.json to the new file as a comment at the top. You must now manually go through all the eslint configs and migrate your custom rules (if you have any).

Check api/eslint.config.mjs, admin/eslint.config.mjs and site/eslint.config.mjs
Migrate custom rules
Remove the comment from the file
Create a commit with --no-verify

🤖 Upgrade Prettier from v2 to v3

Execute the following upgrade script

npx @comet/upgrade@latest v8/prettier-dev-dependencies.ts

Handled by @comet/upgrade

-        "prettier": "^2.8.1",
+        "prettier": "^3.4.2",

After executing the script, create a commit with --no-verify.

Upgrade `@comet/eslint-config` to v8

Yes, you can do that before updating everything else to v8.

Change the version numbers:

api/package.json
-       "@comet/eslint-config": "7.24.0",
+       "@comet/eslint-config": "8.0.0", // replace with the newest v8 version

admin/package.json
-       "@comet/eslint-config": "7.24.0",
+       "@comet/eslint-config": "8.0.0", // replace with the newest v8 version

site/package.json
-       "@comet/eslint-config": "7.24.0",
+       "@comet/eslint-config": "8.0.0", // replace with the newest v8 version

Execute npm install (it might be necessary to use npm install --force)

+       "jsx": "react-jsx",

🤖 Remove React barrel imports

Importing React is no longer necessary due to the new JSX transform, which automatically imports the necessary react/jsx-runtime functions. Use individual named imports instead, e.g, import { useState } from "react".
Execute the following upgrade script:
npx @comet/upgrade@latest v8/remove-react-barrel-imports-admin.ts
Commit your changes with --no-verify
🤖 Ignore import restrictions for @mui/material (this is done temporarily, we'll fix this later during the v8 update)

{
    "dependencies": {
-       "@sentry/node": "^7.0.0",
+       "@sentry/node": "^9.0.0",
    },
}

Update your main.ts file to remove all Sentry.Handlers and add Sentry.setupExpressErrorHandler(app):

-   app.use(Sentry.Handlers.requestHandler());
-   app.use(Sentry.Handlers.tracingHandler());
-   app.use(Sentry.Handlers.errorHandler());
+   Sentry.setupExpressErrorHandler(app);

None of the other breaking changes in @sentry/node should affect us. If you still encounter problems, consult the official migration guides:

✅ `@kubernetes/client-node`

The @kubernetes/client-node peer dependency has been bumped to v1.

Handled by @comet/upgrade

Handled by

npx @comet/upgrade@latest v8/api/before-install/update-kubernetes-client-node.ts

{
    "dependencies": {
-       "@kubernetes/client-node": "^0.18.0",
+       "@kubernetes/client-node": "^1.0.0",
    }
}

✅ Remove `@comet/blocks-api`

The @comet/blocks-api package has been merged into the @comet/cms-api package.

Handled by @comet/upgrade

To upgrade, perform the following steps:

Remove the package:

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/before-install/remove-blocks-packages-api.ts

api/package.json
- "@comet/blocks-api": "^7.x.x",

✅ Remove nestjs-console and install nest-commander

The nestjs-console package isn't actively maintained anymore. We therefore replace it with nest-command.

The upgrade script will remove the nestjs-console package and install nest-commander and @types/inquirer.

Handled by @comet/upgrade

Handled by

npx @comet/upgrade@latest v8/api/before-install/replace-nestjs-console-with-nest-commander.ts

Uninstall nestjs-console
Install nest-commander and @types/inquirer

✅ Remove passport

Handled by @comet/upgrade

Handled by

npx @comet/upgrade@latest v8/api/before-install/remove-passport.ts

Remove all passport-dependencies and add @nestjs/jwt

{
    "dependencies": {
-       "@nestjs/passport": "^9.0.0",
-       ...other passport dependencies
+       "@nestjs/jwt": "^10.2.0",
    }
}

API Generator - Add new package @comet/api-generator

The API Generator has been moved into a separate package @comet/api-generator.

api/package.json
devDependencies: {
+  "@comet/api-generator": "8.0.0", // replace with newest v8 version
}

Install

Now it's time to run npm install:

Enter the /api folder: cd api
Delete node_modules and package-lock.json to avoid false positive errors: rm package-lock.json && rm -rf node_modules
Update @comet/ packages to the newest v8 version. You can find the latest release on Github.
npm install

‼️ It's likely that the install fails ‼️
The upgrade scripts only updates the packages we have in the starter. You probably have more packages that rely on NestJS or MikroORM in your project. Update them by hand based on the errors you are getting and rerun the install!
Once the install passed, commit your changes with --no-verify

🤖 Update the custom formatError function to hide GraphQL field suggestions

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/update-graphql-format-error.ts

Details

- import { ValidationError } from "apollo-server-express";
+ import { ValidationError } from "@nestjs/apollo";

/* ... */

GraphQLModule.forRootAsync<ApolloDriverConfig>({
    /* ... */
    useFactory: (moduleRef: ModuleRef) => ({
        /* ... */,
        formatError: (error) => {
            // Disable GraphQL field suggestions in production
            if (process.env.NODE_ENV !== "development") {
-               if (error instanceof ValidationError) {
+               if (error.extensions?.code === "GRAPHQL_VALIDATION_FAILED") {
                    return new ValidationError("Invalid request.");
                }
            }
            return error;
        },

    }),
}),

You may need to update some of your routes to support Express v5. See the migration guide for more information.

Follow the official migration guide to upgrade.

We provide upgrade scripts for basic migrations. Please note that these scripts might not cover all necessary migrations.

🤖 Replace UseRequestContext with CreateRequestContext:
Execute the following upgrade script:
npx @comet/upgrade@latest v8/api/after-install/mikro-orm-create-request-context.ts

🤖 Replace `@comet/blocks-api` imports with `@comet/cms-api`

The @comet/blocks-api package has been merged into the @comet/cms-api package. Thus, all imports must be updated.

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/merge-blocks-api-into-cms-api.ts

Details

To upgrade, perform the following steps:

Update all your imports from @comet/blocks-api to @comet/cms-api
Update imports that have been renamed
Remove usages of removed export getFieldKeys (probably none)

Execute API generator

npm run api-generator

🤖 Use graphiql instead of GraphQL Playground:

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/replace-playground-with-graphiql.ts

🤖 Change s3 blob-storage config structure

It's now possible to configure the S3-client completely.

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/update-s3-config.ts

Details

Previously configuration had its own structure, now credentials are nested under credentials and the accessKeyId and secretAccessKey are no longer top-level properties. Bucket is not part of s3-config but still required, so it's passed as a top-level property.

blob: {
    storage: {
        driver: envVars.BLOB_STORAGE_DRIVER,
        file: {
            path: envVars.FILE_STORAGE_PATH,
        },
        azure: {
            accountName: envVars.AZURE_ACCOUNT_NAME,
            accountKey: envVars.AZURE_ACCOUNT_KEY,
        },
        s3: {
            region: envVars.S3_REGION,
            endpoint: envVars.S3_ENDPOINT,
            bucket: envVars.S3_BUCKET,
-            accessKeyId: envVars.S3_ACCESS_KEY_ID,
-            secretAccessKey: envVars.S3_SECRET_ACCESS_KEY,
+            credentials: {
+                 accessKeyId: envVars.S3_ACCESS_KEY_ID,
+                 secretAccessKey: envVars.S3_SECRET_ACCESS_KEY,
+            },
        },
    },
    storageDirectoryPrefix: envVars.BLOB_STORAGE_DIRECTORY_PREFIX,
},

🤖 Add `ImgproxyModule` and change config of `BlobStorageModule` and `DamModule`

The FileUploadsModule has been completely separated from the DamModule and now works independently. Some structural changes were necessary to achieve this.

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/move-maxSrcResolution-in-comet-config.ts
npx @comet/upgrade@latest v8/api/after-install/update-dam-configuration.ts

Details

You need to modify your AppModule as follows:

api/src/app.module.ts
    BlobStorageModule.register({
        backend: config.blob.storage,
+       cacheDirectory: `${config.blob.storageDirectoryPrefix}-cache`,
    }),
+   ImgproxyModule.register(config.imgproxy),
    DamModule.register({
        damConfig: {
-           apiUrl: config.apiUrl,
            secret: config.dam.secret,
            allowedImageSizes: config.dam.allowedImageSizes,
            allowedAspectRatios: config.dam.allowedImageAspectRatios,
            filesDirectory: `${config.blob.storageDirectoryPrefix}-files`,
-           cacheDirectory: `${config.blob.storageDirectoryPrefix}-cache`,
            maxFileSize: config.dam.uploadsMaxFileSize,
+           maxSrcResolution: config.dam.maxSrcResolution,
        },
-       imgproxyConfig: config.imgproxy,
        Scope: DamScope,
        File: DamFile,
        Folder: DamFolder,
    }),

Execute the following upgrade script:

npx @comet/upgrade@latest v8/api/after-install/move-maxSrcResolution-in-comet-config.ts

api/src/comet-config.json
{
    "dam": {
        "allowedImageAspectRatios": ["16x9", "4x3", "3x2", "3x1", "2x1", "1x1", "1x2", "1x3", "2x3", "3x4", "9x16"],

    },
    "images": {
        "deviceSizes": [640, 750, 828, 1080, 1200, 1920, 2048, 3840],
        "imageSizes": [16, 32, 48, 64, 96, 128, 256, 320, 384]
    },
    "imgproxy": {
-       "maxSrcResolution": 70,
        "quality": 80
    }
}

Import tracing with `import` instead of `require`

src/main.ts
if (process.env.TRACING_ENABLED === "1") {
-   require("./tracing");
+   import("./tracing");
}

// ...

src/console.ts
// eslint-disable-next-line @typescript-eslint/no-explicit-any
let tracing: any;
if (process.env.TRACING_ENABLED) {
-   tracing = require("./tracing");
+   tracing = import("./tracing");
}

Replace nestjs-console with nest-commander

The nestjs-console package isn't actively maintained anymore. We therefore replace it with nest-command.

You have to perform the following steps manually:

Update api/src/console.ts to use nest-commander. Minimum example:

import { CommandFactory } from "nest-commander";

import { AppModule } from "./app.module";
import { createConfig } from "./config/config";

const config = createConfig(process.env);

async function bootstrap() {
    const appModule = AppModule.forRoot(config);

    // @ts-expect-error CommandFactory doesn't except DynamicModule, only Type<any>
    await CommandFactory.run(appModule, {
        logger: ["error", "warn", "log"],
        serviceErrorHandler: async (error) => {
            console.error(error);
            process.exit(1);
        },
    });
}

bootstrap();

Update your commands to the new nest-commander syntax:

Migrating nestjs-console commands to nest-commander

This section highlights the necessary changes to convert a nestjs-console command to nest-commander.

Replace the @Console() decorator with @Command():

- import { Command, Console } from "nestjs-console";
+ import { Command } from "nest-commander";

- @Injectable()
- @Console()
+ @Command({
+     name: "fixtures",
+     description: "Create fixtures with faker.js",
+ })
export class FixturesConsole {
-   @Command({
-       command: "fixtures",
-       description: "Create fixtures with faker.js",
-   })
    @CreateRequestContext()
    async execute(): Promise<void> {
        /* ... */
    }
}

Extend CommandRunner:

+ import { CommandRunner } from "nest-commander";

- export class FixturesConsole {
+ export class FixturesConsole extends CommandRunner {
    /* ... */
}

Add a super() call to the constructor:

export class FixturesConsole extends CommandRunner {
    constructor(@Inject(CONFIG) private readonly config: Config) {
+       super();
    }
}

Rename the executing function to run:

export class FixturesConsole extends CommandRunner {
    @CreateRequestContext()
-   async execute(): Promise<void> {
+   async run(): Promise<void> {
        /* ... */
    }
}

If necessary, migrate arguments and options.

Arguments: Move from command field into arguments field:

info

Optional arguments must be defined in square brackets [], required arguments in angle brackets <>.

import-redirects.command.ts
@Command({
    name: "import-redirects",
+   arguments: "<filepath> [comment]",
    description: "Import redirects from a CSV file",
})
export class ImportRedirectsCommand extends CommandRunner {
    @Command({
-       command: "import-redirects [filepath] [comment]",
        description: "Import redirects from csv file",
    })
    @CreateRequestContext()
-   async execute(filepath: string, comment = "Imported"): Promise<void> {
+   async run([filepath, comment = "Imported"]: string[]): Promise<void> {
        /* ... */
    }
}

Options: Use the @Option() decorator:

refresh-block-index-views.command.ts
@Command({
    name: "refreshBlockIndexViews",
})
export class RefreshBlockIndexViewsCommand extends CommandRunner {
    @Command({
        command: "refreshBlockIndexViews",
-       options: [
-           {
-               flags: "-f, --force [boolean]",
-               defaultValue: false,
-           },
-       ],
    })
    @CreateRequestContext()
-   async refreshBlockIndexViews(args: { force: boolean }): Promise<void> {
+   async run(arguments: string[], options: { force?: true }): Promise<void> {
        /* ... */
    }

+   @Option({
+       flags: "-f, --force",
+   })
+   parseForce() {}
}

Review the documentation for more information.

Optional: Rename console to command:

- export class FixturesConsole extends CommandRunner {
+ export class FixturesCommand extends CommandRunner {
    /* ... */
}

Remove passport

The passport dependencies were removed before the install. The following steps must be done manually:

info

If you're unsure about how to structure the AuthModule, look at the COMET Starter version.

Rename the strategy-factories and wrap them in ...createAuthGuardProviders():

-   createStaticCredentialsBasicStrategy({ ... }),
-   createAuthProxyJwtStrategy({ ... }),
-   createStaticAuthedUserStrategy({ ... }),
+   ...createAuthGuardProviders(
+       createBasicAuthService({ ... }),
+       createJwtAuthService({ ... }),
+       createStaticUserAuthService({ ... }),
+   ),

Configuration changes

The configuration of the AuthServices have changed slightly compared to the strategies, however they remain similar. Consulting the code completion should help to adapt.

Add the new createSitePreviewAuthService:

    ...createAuthGuardProviders(
        // ...
+       createSitePreviewAuthService({ ... }),
    ),

Replace createCometAuthGuard with the class name:
```
-   useClass: createCometAuthGuard([...]),
+   useClass: CometAuthGuard,
```
Passport not supported anymore
CometAuthGuard does not support Passport strategies anymore. Consider rewriting or wrapping into AuthServiceInterface. However, you still can use passport strategies in conjunction with the provided AuthGuard from @nestjs/passport.

Remove currentUser prop from createAuthResolver:

 createAuthResolver({
    // ...
-   currentUser: CurrentUser,
 }),

Import JwtModule from @nestjs/jwt:

    exports: [UserService, AccessControlService],
+   imports: [JwtModule],

Use strings for date-only columns

warning

This change only applies to date-only columns, meaning columns where we only want to save the date without a time.

It does not apply to timestamps, where we save the date and time (e.g., createdAt or updatedAt). For these cases, you don't have to change anything.

Starting with v6 MikroORM maps date-only columns to string instead of Date. Perform the following changes:

Use string instead of Date for date-only columns:

class Product {
    @Property({ type: types.date, nullable: true })
    @Field(() => GraphQLDate, { nullable: true })
-   availableSince?: Date = undefined;
+   availableSince?: string = undefined;
}

Use GraphQLLocalDate instead of GraphQLDate:

- import { GraphQLDate } from "graphql-scalars";
+ import { GraphQLLocalDate } from "graphql-scalars";

class Product {
    @Property({ type: types.date, nullable: true })
-   @Field(() => GraphQLDate, { nullable: true })
+   @Field(() => GraphQLLocalDate, { nullable: true })
    availableSince?: string = undefined;
}

Why this change?

The GraphQLDate scalar coerces strings (e.g., 2025-06-30) to Date objects when used as an input type, whereas the GraphQLLocalDate performs no type coercion.

Pass metadata to `gqlArgsToMikroOrmQuery`

You now need to pass the entity metadata instead of the repository to gqlArgsToMikroOrmQuery:

src/**/your.resolver.ts
-       const where = gqlArgsToMikroOrmQuery({ filter, search }, this.repository);
+       const where = gqlArgsToMikroOrmQuery({ filter, search }, this.entityManager.getMetadata(YourEntity));

Typed Permissions System

Search for all @CrudGenerator or @RequiredPermission decorators and move all permissions into the AppPermission enum. Add also module augmentation for PermissionOverrides to include the new AppPermission enum.

Create a new AppPermission enum:

api/src/auth/app-permission.enum.ts
export enum AppPermission {
    news = "news",
    products = "products",
    manufacturers = "manufacturers",
}

Add AppPermission to UserPermissionsModule:

api/src/app.module.ts
UserPermissionsModule.forRootAsync({
    useFactory: (userService: UserService, accessControlService: AccessControlService) => ({
        ...
    }),
    inject: [UserService, AccessControlService],
    imports: [authModule],
+   AppPermission,
}),

Create a new file and add module augmentation for PermissionOverrides:

api/src/auth/permission.interface.ts
import { type AppPermission } from "@src/auth/app-permission.enum";

declare module "@comet/cms-api" {
    export interface PermissionOverrides {
        app: AppPermission;
    }
}

Update all @CrudGenerator decorators where required permissions are not defined:

api/src/news/entities/news.entity.ts
-@CrudGenerator({ targetDirectory: `${__dirname}/../generated/` })
+@CrudGenerator({ targetDirectory: `${__dirname}/../generated/`, requiredPermission: ["news"] })

In admin, also add module augmentation for PermissionOverrides with created types from GraphQL Codegen:

demo/admin/src/App.tsx
+import type { GQLPermission } from "@src/graphql.generated";
...
declare module "@comet/cms-admin" {
    // eslint-disable-next-line @typescript-eslint/no-empty-object-type
    interface ContentScope extends BaseContentScope {}
+
+   export interface PermissionOverrides {
+       permission: GQLPermission;
+   }
}

API Generator - Removed Special `status` Field Behavior

Previously, if entities specified a status enum, it was automatically added to list queries arguments with a default value.

This special handling has been removed. The status field now behaves like a normal enum. Filtering by status can be done with the normal filtering mechanism.

API Generator - Don't commit generated files

The improved performance of API Generator doesn't make it necessary anymore to add generated files to git. You can remove previously generated files and generate them on demand:

Run api-generator in prebuild:

api/package.json
scripts: {
-  "prebuild": "rimraf dist",
+  "prebuild": "rimraf dist && npm run api-generator",
}

Remove lint:generated-files-not-modified and execute npm run api-generator before lint:

api/package.json
scripts: {
-  "lint:generated-files-not-modified": "npm run api-generator && git diff --exit-code HEAD -- src/**/generated",
-  "lint": "npm run lint:eslint && npm run lint:tsc",
-  "lint:ci": "npm run lint && npm run lint:generated-files-not-modified",
+  "lint": "npm run api-generator && run-p lint:eslint lint:tsc",
+  "lint:ci": "npm run lint",
}

Add generated files to eslint ignore:

api/eslint.config.mjs
scripts: {
-  ignores: ["src/db/migrations/**", "dist/**", "src/**/*.generated.ts"],
+  ignores: ["src/db/migrations/**", "dist/**", "src/**/*.generated.ts", "src/**/generated/**"],
}

Add generated files to .gitignore:
api/.gitignore
```
+ # API generator
+ src/**/generated
```
And finally delete generated files from git:
```
git rm -r --cached api/src/*/generated
```

Use MUI pickers for `DataGrid` Date / DateTime filters

Handled by @comet/upgrade

Handled by

npx @comet/upgrade@latest v8/admin/before-install/use-mui-date-picker-in-grid.ts

This update improves the UX of date filtering by replacing the current date picker solution with MUI's DatePicker.

It requires installation of new dependencies and setup of LocalizationProvider in your app.

Migration steps:

Install dependencies: Add the following dependencies to your package.json:

    "dependencies": {
+       "@mui/x-date-pickers": "^7.29.4",
+       "date-fns": "^4.1.0",
    }

Update your application root to include `LocalizationProvider from @mui/x-date-pickers:

+    import { LocalizationProvider } from "@mui/x-date-pickers";
+    import { AdapterDateFns } from "@mui/x-date-pickers/AdapterDateFnsV3";
+    import { enUS } from "date-fns/locale";

    <IntlProvider locale="en" messages={getMessages()}>
+        <LocalizationProvider adapterLocale={enUS} dateAdapter={AdapterDateFns}>
            <MuiThemeProvider theme={theme}>{/* App Content */}</MuiThemeProvider>
+        </LocalizationProvider>
    </IntlProvider>;

If you are already using the dataGridDateColumn or dataGridDateTimeColumn helpers, the new MUI DatePicker will be used automatically for filtering:

import { dataGridDateTimeColumn } from "@comet/admin";

const columns: GridColDef[] = [
    {
        ...dataGridDateTimeColumn,
        field: "createdAt",
        headerName: "Created at",
    },
];

Action required

If your application uses internationalization or a language other than English (US), additional configuration is required. The codemod will add a TODO comment at the relevant location to remind you to configure the appropriate locale for the LocalizationProvider.

Add new package @comet/admin-generator

The Admin Generator has been moved into a separate package @comet/admin-generator.

admin/package.json
devDependencies: {
+  "@comet/admin-generator": "8.0.0", // replace with the newest v8 version
}

Install

Now it's time to run npm install:

Enter the /admin folder: cd admin
Delete node_modules and package-lock.json to avoid false positive errors: rm package-lock.json && rm -rf node_modules
Update @comet/ packages to the newest v8 version. You can find the latest release on Github.
npm install

‼️ It's likely that the install fails ‼️
The upgrade scripts only updates the packages we have in the starter. You probably have more packages that rely on MUI or React in your project. Update them by hand based on the errors you are getting and rerun the install!
Once the install passed, commit your changes with --no-verify

Remove `@comet/blocks-admin`

The @comet/blocks-admin package has been merged into the @comet/cms-admin package.

🤖 Update all imports:
Execute the following upgrade script:
npx @comet/upgrade@latest v8/admin/after-install/clipboard-helpers.ts npx @comet/upgrade@latest v8/admin/after-install/merge-blocks-admin-into-cms-admin.ts
Details
To upgrade, perform the following steps:
1. Update all your imports from @comet/blocks-admin to @comet/cms-admin
2. Update imports that have been renamed
Manually remove usages of removed exports CannotPasteBlockDialog, ClipboardContent, useBlockClipboard, Collapsible, CollapsibleSwitchButtonHeader, usePromise, DispatchSetStateAction, SetStateAction, and SetStateFn

tip
Use Dispatch<SetStateAction<T>> from react instead of DispatchSetStateAction.

🤖 Remove `@comet/admin-theme`

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/merge-admin-theme-into-admin.ts

Handled by @comet/upgrade

The @comet/admin-theme package has been merged into @comet/admin, adjust the imports accordingly:

- import { createCometTheme } from "@comet/admin-theme";
+ import { createCometTheme } from "@comet/admin";

  const theme = createCometTheme();

Remove `@comet/admin-react-select`

@comet/admin-react-select was removed. It is recommended to use the AutocompleteField or the SelectField components from @comet/admin instead:

- import { FinalFormReactSelectStaticOptions } from "@comet/admin-react-select";
- <Field name="color" type="text" component={FinalFormReactSelectStaticOptions} fullWidth options={options} />;
+ import { AutocompleteField } from "@comet/admin";
+ <AutocompleteField name="color" label="Color" options={options} fullWidth />;

Add proxy for `/api` and `/dam` URLs

In our deployed setup, all API requests from the admin are routed through the AuthProxy that runs under the admin domain. To be closer to this setup, we now also do that locally:

.env
 # api
 API_PORT=4000
-API_URL=http://${DEV_DOMAIN:-localhost}${WORKAROUND_DOTENV_ISSUE}:${API_PORT}/api # or similar
+API_URL=$ADMIN_URL/api

Also, the API now only returns relative URLs for DAM assets. You must proxy the /dam URLs in your application to the API. This must be done for local development and production.

In development:

Add the proxy to your vite config:

admin/vite.config.mts
//...
server: {
    // ...
    cors: false,
    proxy: process.env.API_URL_INTERNAL
    ? {
         "/api": {
            target: new URL(process.env.API_URL_INTERNAL).origin,
            changeOrigin: true,
            secure: false,
         },
        "/dam": {
            target: process.env.API_URL_INTERNAL,
            changeOrigin: true,
            secure: false,
        },
    }
    : undefined,
    // ...
},
//...

or in your webpack config (for old projects):

admin/webpack.config.ts
const config = (env: unknown, argv: Argv): webpack.Configuration => {
    // ...
    return {
        // ...
        devServer: {
            // ...
            proxy: process.env.API_URL_INTERNAL
                ? {
                      "/api": {
                          target: new URL(process.env.API_URL_INTERNAL).origin,
                          changeOrigin: true,
                          secure: false,
                      },
                      "/dam": {
                          target: process.env.API_URL_INTERNAL,
                          changeOrigin: true,
                          secure: false,
                      },
                  }
                : undefined,
        },
    };
};

In production:

Add the proxy to your admin server:

admin/server/package.json
"dependencies": {
    // ...
+   "http-proxy-middleware": "^3.0.3"
    // ...
},

admin/server/index.js
+   const { createProxyMiddleware } = require("http-proxy-middleware");

    // ...

    app.get("/status/health", (req, res) => {
        // ...
    });

+   const proxyMiddleware = createProxyMiddleware({
+       target: process.env.API_URL_INTERNAL + "/dam",
+       changeOrigin: true,
+   });
+   app.use("/dam", proxyMiddleware);

    // ...

You might also need to add API_URL_INTERNAL to your values.tpl.yaml for deployment:

deployment/helm/values.tpl.yaml
admin:
    env:
        ADMIN_URL: "https://$ADMIN_DOMAIN"
        API_URL: "https://$ADMIN_DOMAIN/api"
+       API_URL_INTERNAL: "http://$APP_NAME-$APP_ENV-api:3000/api"

🤖 Merge providers into `CometConfigProvider`

The separate providers for CMS features (e.g, DamConfigProvider) have been merged into a CometConfigProvider.

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/comet-config-provider.ts

Note: This upgrade script is experimental and might not work as expected in your application. Review the result carefully.

Handled by @comet/upgrade

Wrap your application with the CometConfigProvider:

src/App.tsx
import { CometConfigProvider } from "@comet/cms-admin";

function App() {
    return (
        <CometConfigProvider
            apiUrl={config.apiUrl}
            graphQLApiUrl={`${config.apiUrl}/graphql`}
            adminUrl={config.adminUrl}
        >
            {/* Application */}
        </CometConfigProvider>
    );
}

Move module configs to the new provider:

 <CometConfigProvider
     apiUrl={config.apiUrl}
     graphQLApiUrl={`${config.apiUrl}/graphql`}
     adminUrl={config.adminUrl}
+    dam={{
+        ...config.dam,
+        scopeParts: ["domain"],
+        contentGeneration: {
+            generateAltText: true,
+            generateImageTitle: true,
+        },
+    }}
 >
     {/* Application */}
 </CometConfigProvider>

Remove the old config providers:

- <DamConfigProvider>
      {/* Application */}
- </DamConfigProvider>

Update usages of renamed exports:

useSitesConfig() -> useSiteConfigs()
useLocale() -> useContentLanguage()
useCmsBlockContext() -> useBlockContext()

Remove the allCategories prop from PagesPage:

 <PagesPage
     path="/pages/pagetree/main-navigation"
-    allCategories={pageTreeCategories}
     documentTypes={pageTreeDocumentTypes}
     category="MainNavigation"
     renderContentScopeIndicator={(scope) => <ContentScopeIndicator scope={scope} />}
 />

Experimental upgrade script

This upgrade script is experimental and might not work as expected in your application. Review the result carefully.

Adapt to changes in ContentScopeProvider

Use interface augmentation for ContentScope

admin/src/App.tsx
+   import { type ContentScope as BaseContentScope } from "@src/site-configs";

+   declare module "@comet/cms-admin" {
+       // eslint-disable-next-line @typescript-eslint/no-empty-object-type
+       interface ContentScope extends BaseContentScope {}
+   }

    export function App() {

The ContentScopeInterface export from @comet/cms-admin was removed. Instead, use ContentScope directly:

- import { type ContentScopeInterface } from "@comet/cms-admin";
+ import { type ContentScope } from "@comet/cms-admin";

Preferably use ContentScopeProvider directly from Comet

Move the scope labels from admin to the API, for example:

api/src/app.module
UserPermissionsModule.forRootAsync({
    useFactory: (userService: StaticUsersUserService, accessControlService: AccessControlService) => ({
        availableContentScopes: config.siteConfigs.flatMap((siteConfig) =>
-           siteConfig.scope.languages.map((language) => ({
-               domain: siteConfig.scope.domain,
-               language,
-           })),
+           siteConfig.scope.languages.map((language) => ({
+               scope: {
+                   domain: siteConfig.scope.domain,
+                   language,
+               },
+               label: { domain: siteConfig.name },
+           })),
        ),
        // ...
    }),
    // ...
}),

Then you can use the ContentScopeProvider from @comet/cms-admin directly in your App.tsx and delete admin/src/common/ContentScopeProvider.tsx:

admin/src/App.tsx
-   import { ContentScopeProvider } from "./common/ContentScopeProvider";
+   import { ContentScopeProvider } from "@comet/cms-admin";
    // Delete `admin/src/common/ContentScopeProvider.tsx`

You should also use useContentScope from @comet/cms-admin.

However, if you need custom behavior, you can keep admin/src/common/ContentScopeProvider.tsx while skipping above change.

Make sure to remove the generics:

admin/src/common/ContentScopeProvider.tsx
-   export function useContentScopeConfig(p: ContentScopeConfigProps): void {
-       return useContentScopeConfigLibrary(p);
-   }

-    ContentScopeValues<ContentScope>
+    ContentScopeValues
-    <ContentScopeProviderLibrary<ContentScope>>
+    <ContentScopeProviderLibrary>

The React dependency has been bumped to v18.

Follow the official migration guide to upgrade.

Update to client rendering API

admin/src/loader.ts
- ReactDOM.render(createElement(App), rootElement);
+ const root = createRoot(rootElement);
+ root.render(createElement(App));

info

Otherwise, there's probably not much to do here. You can also fix potential errors later during the lint step.

tip

Use types-react-codemod to fix potential TypeScript compile errors when upgrading to @types/react@^18.0.0.

The MUI dependencies (@mui/material, @mui/system, @mui/utils, @mui/icons-material, @mui/lab) were bumped to v7.

🤖 Execute MUI codemods to update your code
Execute the following upgrade script:
npx @comet/upgrade@latest v8/admin/after-install/mui-codemods.ts
info
When executing the codemods, some errors relating to fragmentTypes.json or comet-config.json can occur. You can just ignore them.
Follow the official migration guides to upgrade:
- Upgrade to MUI v6
- Upgrade to MUI v7
  info
  Probably, there's not much to do here. You can also fix potential errors later during the lint step.

The MUI dependencies (@mui/x-data-grid, @mui/x-data-grid-pro) were bumped to v7.

Search for columns with the type: "dateTime". You must add a valueGetter:

    <DataGrid
        //other props
        columns=[
        {
            field: "updatedAt",
            type: "dateTime",
+           valueGetter: (params, row) => row.updatedAt && new Date(row.updatedAt)
        }]
    />

Search for valueGetter and valueFormatter

Change the arguments passed to the functions. Previously, arguments were passed as an object. Now, they are passed directly as individual parameters

    <DataGrid
        //other props
        columns=[
        {
            field: "updatedAt",
            type: "dateTime",
-           valueGetter: ({params, row}) => row.updatedAt && new Date(row.updatedAt)
+           valueGetter: (params, row) => row.updatedAt && new Date(row.updatedAt)
-           valueFormatter: ({value}) => (value ? intl.formatDate(value, { dateStyle: "medium", timeStyle: "short" }) : ""),
+           valueFormatter: (value) => (value ? intl.formatDate(value, { dateStyle: "medium", timeStyle: "short" }) : ""),
        }]
    />

A lots of props have been renamed from MUI, for a detailed look, see the official migration guide v5 -> v6 and migration guide v6 -> v7.

There is also a codemod from MUI which handles most of the changes:
Execute the following upgrade script:
npx @comet/upgrade@latest v8/admin/after-install/mui-x-codemods.ts

Update usage of `DataGridToolbar`

DataGridToolbar has been simplified to a basic wrapper component. Props and features from the standard Toolbar component have been removed, along with the density prop since density is now controlled by the DataGrid.

The new usage simplifies the component structure - children can now be passed directly without needing to wrap them in ToolbarItem and ToolbarActions components:

- <DataGridToolbar density="compact">
+ <DataGridToolbar>
-     <ToolbarItem>
          <GridToolbarQuickFilter />
-     </ToolbarItem>
-     <ToolbarItem>
          <GridFilterButton />
-     </ToolbarItem>
-     <ToolbarItem>
          <GridColumnsButton />
-     </ToolbarItem>
      <FillSpace />
-     <ToolbarActions>
          <Button responsive variant="outlined">
              Secondary action
          </Button>
          <Button responsive startIcon={<AddIcon />}>
              Add item
          </Button>
-     </ToolbarActions>
  </DataGridToolbar>

🤖 Pass columns instead of apiRef to `muiGridSortToGql` Function

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/mui-grid-sort-to-gql.ts

Note: This upgrade script will naively change the second argument of muiGridSortToGql function to columns, assuming that columns is available in the current scope.

Details

The muiGridSortToGql helper now expects the columns instead of the apiRef:

const columns : GridColDef[] = [/* column definitions*/];
const dataGridRemote = useDataGridRemote();
const persistentColumnState = usePersistentColumnState("persistent_column_state");

-  muiGridSortToGql(dataGridRemote.sortModel, persistentColumnState.apiRef);
+  muiGridSortToGql(dataGridRemote.sortModel, columns);

Naive upgrade script

This upgrade script will naively change the second argument of muiGridSortToGql function to columns, assuming that columns is available in the current scope.

Remove `error` prop from DataGrid

The error and onError props were removed - the grid no longer catches errors during rendering. To catch errors that happen during rendering use the error boundary. The components.ErrorOverlay slot was also removed.

– MUI migration guide

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/mui-data-grid-remove-error-prop.ts

Note: Error handling must be implemented manually, the upgrade script simply removes all usages of the error prop on DataGrids and adds a TODO: comment.

Error handling must be implemented manually

This upgrade script simply removes all usages of the error prop on DataGrids and adds a TODO: comment. Error handling must be implemented manually.

The recommended way to handle errors is to use the ErrorBoundary in the parent component and throw errors where the query error happens.

- const { loading, data, error } = useQuery(/* query parameters */)
- <DataGrid error={error} /* other props */ >

+ const { loading, data, error } = useQuery(/* query parameters */)
+ if (error) {
+     throw error
+ }
+ <DataGrid /* other props */ >

`useDataGridRemote` Hook - Return Value

The useDataGridRemote hook has been changed to match the updated DataGrid props:

- const { pageSize, page, onPageSizeChange } = useDataGridRemote();
+ const { paginationModel, onPaginationModelChange } = useDataGridRemote();

rowCount must be passed

Be aware that you must pass rowCount to the DataGrid when using the useDataGridRemote hook. Otherwise, the pagination component will show a NaN value when used with server-side pagination.

i18n for MUI X date picker

In the before-install script, a LocalizationProvider was added to App.tsx. A adapterLocale is passed to the provider. If your application uses internationalization or a language other than English (US), make sure to pass the right locale based on the supported languages.

🤖 Rename `Menu` and related components to `MainNavigation` in `@comet/admin`

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/rename-menu-components-in-admin.ts

Handled by @comet/upgrade

To better differentiate between imports from @comet/admin and @mui/material, the following components and related types have been renamed:

Menu → MainNavigation
MenuProps → MainNavigationProps
MenuClassKey → MainNavigationClassKey
MenuItem → MainNavigationItem
MenuItemProps → MainNavigationItemProps
MenuItemClassKey → MainNavigationItemClassKey
MenuCollapsibleItem → MainNavigationCollapsibleItem
MenuCollapsibleItemProps → MainNavigationCollapsibleItemProps
MenuCollapsibleItemClassKey → MainNavigationCollapsibleItemClassKey
IWithMenu → WithMainNavigation
withMenu → withMainNavigation
MenuItemAnchorLink → MainNavigationItemAnchorLink
MenuItemAnchorLinkProps → MainNavigationItemAnchorLinkProps
MenuItemGroup → MainNavigationItemGroup
MenuItemGroupClassKey → MainNavigationItemGroupClassKey
MenuItemGroupProps → MainNavigationItemGroupProps
MenuItemRouterLink → MainNavigationItemRouterLink
MenuItemRouterLinkProps → MainNavigationItemRouterLinkProps

The MenuContext has been removed, use the new useMainNavigation hook instead.

🤖 Import `Dialog` from `@comet/admin` package

warning

Dialog now supports a title prop that automatically adds a DialogTitle component. So if you have a Dialog with a DialogTitle as a child, you should remove the DialogTitle and pass its children as title prop to Dialog.

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/update-import-of-dialog.ts

Details

- import { Dialog } from "@mui/material";
+ import { Dialog } from "@comet/admin";

🤖 Add `DialogContent` to `EditDialog`

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/add-dialog-content-to-edit-dialog.ts

Details

The DialogContent inside EditDialog has been removed. To maintain the existing styling of EditDialog, such as for forms and text, manually wrap the content with DialogContent to ensure proper spacing. For grids or other elements that already handle their own spacing (e.g., DataGrid), adding DialogContent is not necessary.

    <EditDialog>
    //...
+       <DialogContent>
+           //...
+       </DialogContent>
    // ...
    </EditDialog>

🤖 Import `Tooltip` from `@comet/admin` package

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/tooltip-1-update-import.ts

Details

- import { Tooltip } from "@mui/material";
+ import { Tooltip } from "@comet/admin";

🤖 Remove `trigger` prop from `Tooltip`

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/tooltip-2-remove-trigger-prop.ts

Details

The trigger prop has been removed. The combined hover/focus trigger is now the only supported behavior.

Example:

<Tooltip
- trigger="hover"
></Tooltip>

🤖 Import `Button` from `@comet/admin` package

Execute the following upgrade script:

npx @comet/upgrade@latest v8/admin/after-install/replace-mui-button-with-comet-admin-button.ts

Details

- import { Button } from "@mui/material";
+ import { Button } from "@comet/admin";

Choose correct `Button` variant

The Button from @comet/admin only has a smaller set of variants defined by UX:

type Variant =
    | "primary"
    | "secondary"
    | "outlined"
    | "destructive"
    | "success"
    | "textLight"
    | "textDark";

You must choose visually, which variant is correct for you. Probably the two most common cases are:

- <Button color="primary" variant="contained" />
+ <Button />

- <Button variant="text" />
+ <Button variant="textDark" />

`FinalFormToggleButtonGroup` deprecated

FinalFormToggleButtonGroup has been deprecated and a new component ToggleButtonGroupField got introduced that has the Final Form Field wrapped around it.

- import { FinalFormToggleButtonGroup } from "@comet/cms-admin";
+ import { ToggleGroupButtonField } from "@comet/admin";

...
+ FormValueType = "value1" | "value2";

- <Field
-   name="formValue"
-   label={"Field Label"}
-   component={FinalFormToggleButtonGroup}
-   options={[
-       { value: "value1", icon: <Info /> },
-       { value: "value2", icon: <Error /> },
-   ]}
-   optionsPerRow={2}
- />
+ <ToggleGroupButtonField<FormValueType>
+    name="formValue"
+    label={"Field Label"}
+    options={[
+        { value: "value1", label: <Info /> },
+        { value: "value2", label: <Error /> },
+    ]}
+    optionsPerRow={2}
+    />

The FinalFormToggleButtonGroup component is still available, but moved from @comet/cms-admin to @comet/admin package. Furthermore, the value icon in the options prop has been renamed to label.

- <Field
-   name="formValue"
-   label={"Field Label"}
-   component={FinalFormToggleButtonGroup}
-   options={[
-       { value: "value1", icon: <Info /> },
+       { value: "value1", label: <Info /> },
-       { value: "value2", icon: <Info /> },
+       { value: "value2", label: <Info /> },
-   ]}
-   optionsPerRow={2}
- />

Add the `LocalDate` scalar to the GraphQL Codegen config

admin/codegen.ts
scalars: rootBlocks.reduce(
    (scalars, rootBlock) => ({ ...scalars, [rootBlock]: rootBlock }),
+   { LocalDate: "string" }
)

`DashboardWidgetRoot` / `LatestContentUpdates` no longer handles Grid layout

The DashboardWidgetRoot / LatestContentUpdates component no longer wraps its children in a <Grid> component. This means that layout and sizing must now be handled by the parent component.

Migration steps `DashboardWidgetRoot:

Before:
DashboardWidgetRoot automatically wrapped its content in a grid item, e.g.
```
<DashboardWidgetRoot>{/* widget content */}</DashboardWidgetRoot>
```

After:
You must now wrap DashboardWidgetRoot in a <Grid item> yourself:

<Grid size={{ xs: 12, lg: 6 }}>
    <DashboardWidgetRoot>{/* widget content */}</DashboardWidgetRoot>
</Grid>

Migration steps LatestContentUpdates:

Before:
```
<LatestContentUpdates />
```

After:

<Grid size={{ xs: 12, lg: 6 }}>
    <LatestContentUpdates />
</Grid>

Action required:
Review all usages of DashboardWidgetRoot / LatestContentUpdates in your dashboards and ensure they are wrapped in a <Grid> (or another layout component as appropriate). This gives you full control over widget placement and sizing.

Move redirects `scopeParts` to `CometConfigProvider`.

Previously scopeParts were passed to createRedirectsPage. Those need to be removed:

const RedirectsPage = createRedirectsPage({
    customTargets: { news: NewsLinkBlock },
-   scopeParts: ["domain"],
});

Instead add the redirect config to your CometConfigProvider:

 <CometConfigProvider
    apiUrl={config.apiUrl}
    graphQLApiUrl={`${config.apiUrl}/graphql`}
    adminUrl={config.adminUrl}
    dam={{
        ...config.dam,
        scopeParts: ["domain"],
        contentGeneration: {
            generateAltText: true,
            generateImageTitle: true,
        },
    }}
+   redirects={{
+       scopeParts: ["domain"]
+   }}
 >
     {/* Application */}
 </CometConfigProvider>

Rework `createRedirectsPage` usage to accept `linkBlock` instead of `customTargets`.

Previously, customTargets were passed directly:

const RedirectsPage = createRedirectsPage({
    customTargets: { news: NewsLinkBlock },
});

Now, you should first create the RedirectsLinkBlock and then provide it to createRedirectsPage:

export const RedirectsLinkBlock = createRedirectsLinkBlock({
    news: NewsLinkBlock,
});

export const RedirectsPage = createRedirectsPage({
    linkBlock: RedirectsLinkBlock,
});

This change was made because RedirectsLinkBlock is also needed by RedirectDependency, and can therefore be reused.
