Several changes to the ng analytics command syntax.
- ng analytics project <setting> has been replaced with ng analytics <setting>
- ng analytics <setting> has been replaced with ng analytics <setting> --global
Support for Node.js v12 has been removed as it will become EOL on 2022-04-30. Please use Node.js v14.15 or later.
Support for TypeScript 4.4 and 4.5 has been removed. Please update to TypeScript 4.6.
--all option from ng update has been removed without replacement. To update packages which don’t provide ng update capabilities in your workspace package.json use npm update, yarn upgrade-interactive or yarn upgrade instead.
Deprecated option --prod has been removed from all builders. --configuration production/-c production should be used instead if the default configuration of the builder is not configured to production.
Deprecated ng x18n and ng i18n-extract commands have been removed in favor of ng extract-i18n.
Several changes in the Angular CLI commands and arguments handling.
- ng help has been removed in favour of the —-help option.
- ng —-version has been removed in favour of ng version and ng v.
- Deprecated camel cased arguments are no longer supported. Ex. using —-sourceMap instead of —-source-map will result in an error.
- ng update, —-migrate-only option no longer accepts a string of migration name, instead use —-migrate-only -—name <migration-name>.
- —-help json help has been removed. ### @angular-devkit/build-angular
browser and karma builders script and styles options input files extensions are now validated.

Valid extensions for scripts are: - .js - .cjs - .mjs - .jsx - .cjsx - .mjsx

Valid extensions for styles are: - .css - .less - .sass - .scss - .styl - We now issue a build time error since importing a CSS file as an ECMA module is non standard Webpack specific feature, which is not supported by the Angular CLI.

This feature was never truly supported by the Angular CLI, but has as such for visibility. - Reflect metadata polyfill is no longer automatically provided in JIT mode Reflect metadata support is not required by Angular in JIT applications compiled by the CLI. Applications built in AOT mode did not and will continue to not provide the polyfill. For the majority of applications, the reflect metadata polyfill removal should have no effect. However, if an application uses JIT mode and also uses the previously polyfilled reflect metadata JavaScript APIs, the polyfill will need to be manually added to the application after updating. To replicate the previous behavior, the core-js package should be manually installed and the import 'core-js/proposals/reflect-metadata'; statement should be added to the application's polyfills.ts file. - NG_BUILD_CACHE environment variable has been removed. cli.cache in the workspace configuration should be used instead. - The deprecated showCircularDependencies browser and server builder option has been removed. The recommended method to detect circular dependencies in project code is to use either a lint rule or other external tools.

@angular-devkit/core

parseJson and ParseJsonOptions APIs have been removed in favor of 3rd party JSON parsers such as jsonc-parser.
The below APIs have been removed without replacement. Users should leverage other Node.js or other APIs.
- fs namespace
- clean
- mapObject ### @angular-devkit/schematics
Schematics NodePackageInstallTask will not execute package scripts by default The NodePackageInstallTask will now use the package manager's --ignore-scripts option by default. The --ignore-scripts option will prevent package scripts from executing automatically during an install. If a schematic installs packages that need their install/postinstall scripts to be executed, the NodePackageInstallTask now contains an allowScripts boolean option which can be enabled to provide the previous behavior for that individual task. As with previous behavior, the allowScripts option will prevent the individual task's usage of the --ignore-scripts option but will not override the package manager's existing configuration.
Deprecated analytics property has been removed from TypedSchematicContext interface ### @ngtools/webpack
ivy namespace has been removed from the public API.
- ivy.AngularWebpackPlugin -> AngularWebpackPlugin
- ivy.AngularPluginOptions -> AngularPluginOptions ## Deprecations ### @angular/cli
The defaultCollection workspace option has been deprecated in favor of schematicCollections.

Before json "defaultCollection": "@angular/material"

After json "schematicCollections": ["@angular/material"] - The defaultProject workspace option has been deprecated. The project to use will be determined from the current working directory.

@angular-devkit/core

- ContentHasMutatedException, InvalidUpdateRecordException, UnimplementedException and MergeConflictException symbol from @angular-devkit/core have been deprecated in favor of the symbol from @angular-devkit/schematics.
- UnsupportedPlatformException - A custom error exception should be created instead. ### @angular-devkit/schematics-cli | Commit | Description | | -- | -- | | | replace parser with yargs-parser | ###
