As always we recommend that you update your existing workspaces by using ng update as we provide some helpful schematics to help migrate your workspaces to the latest and greatest.

However, please note that the angular-eslint package itself now supports being referenced as the schematics collection, so...

IF YOU ARE ALREADY USING angular-eslint and ESLint v9 and flat config you can now do the following:

ng update @angular/core @angular/cli angular-eslint

(Note: If you encounter any issues with this, you may need to update to the latest v18 release of angular-eslint first)

IF YOU ARE STILL USING @angular-eslint/schematics and ESLint v8 and .eslintrc.json configs you can still do the following:

ng update @angular/core @angular/cli @angular-eslint/schematics

NOTE: There will not be any migration of your setup to ESLint v9 or flat configs for existing ESLint v8 workspaces while migrating to angular-eslint v19.

We will explore landing an opt in migration schematic in a minor release after 19.0.0.
