Breaking Changes

@angular-devkit/build-angular

• breaking

  Support for karma-coverage-instanbul-reporter has been dropped in favor of the official karma coverage plugin karma-coverage.

• breaking

  Support for node-sass has been removed. sass will be used by default to compile SASS and SCSS files.

• breaking

  NG_PERSISTENT_BUILD_CACHE environment variable option no longer have effect. Configure cli.cache in the workspace configuration instead.

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "cli": {
    "cache": {
      "enabled": true,
      "path": ".custom-cache-path",
      "environment": "all"
    }
  }
  ...
}

• breaking

  The automatic inclusion of Angular-required ES2015 polyfills to support ES5 browsers has been removed. Previously when targetting ES5 within the application's TypeScript configuration or listing an ES5 requiring browser in the browserslist file, Angular-required polyfills were included in the built application. However, with Angular no longer supporting IE11, there are now no browsers officially supported by Angular that would require these polyfills. As a result, the automatic inclusion of these ES2015 polyfills has been removed. Any polyfills manually added to an application's code are not affected by this change.

• breaking

  With this change a number of deprecated dev-server builder options which proxied to the browser builder have been removed. These options should be configured in the browser builder instead.

  The removed options are:

  • aot

  • sourceMap

  • deployUrl

  • baseHref

  • vendorChunk

  • commonChunk

  • optimization

  • progress

• breaking

  With this change we removed several deprecated builder options

• breaking

  extractCss has been removed from the browser builder. CSS is now always extracted.

• breaking

  servePathDefaultWarning and hmrWarning have been removed from the dev-server builder. These options had no effect.

• breaking

  Deprecated @angular-devkit/build-angular:tslint builder has been removed. Use github.com/angular-eslint/angular-eslint instead.

• breaking

  Differential loading support has been removed. With Angular no longer supporting IE11, there are now no browsers officially supported by Angular that require ES5 code. As a result, differential loading's functionality for creating and conditionally loading ES5 and ES2015+ variants of an application is no longer required.

• breaking

  TypeScript versions prior to 4.4 are no longer supported.

• breaking

  The dev-server now uses WebSockets to communicate changes to the browser during HMR and live-reloaded. If during your development you are using a proxy you will need to enable proxying of WebSockets.

• breaking

  We remove inlining of Google fonts in WOFF format since IE 11 is no longer supported. Other supported browsers use WOFF2.
