Angular Upgrade Planner

Commit or stash all work, then make sure you are on the latest minor/patch of your current major before running ng update. Upgrade exactly one major at a time and run the app/tests after each hop.

Angular 12 requires Node.js 12.14 or newer and TypeScript 4.2+.

Update the core framework and CLI together. This applies the official automatic migration schematics for this version.

ng update @angular/core@12 @angular/cli@12

Angular 12 deprecates View Engine; the framework is effectively Ivy-only going forward. Production build becomes the default for ng build, and IE11 support is deprecated.

node-sass is no longer supported. Run the Sass migration and switch your styles to dart-sass. Nullish coalescing (??) is now supported in templates.

Angular 13 requires a current Node.js (12.20+, 14.15+, or 16.10+) and TypeScript 4.4. RxJS is upgraded to 7.4 for new apps.

Update the core framework and CLI together. This applies the official automatic migration schematics for this version.

ng update @angular/core@13 @angular/cli@13

View Engine is completely removed — every library must ship Ivy (ngcc is gone). Internet Explorer 11 support is removed. Lazy routes use dynamic import(). Upgrade RxJS to 7 and review typing changes.

ModuleWithProviders now requires a generic type, entryComponents is no longer needed/used, and renderModuleFactory is removed. The migration fixes most of these automatically.

Angular 14 requires Node.js 14.15+ or 16.10+ and TypeScript 4.6 to 4.8.

Update the core framework and CLI together. This applies the official automatic migration schematics for this version.

ng update @angular/core@14 @angular/cli@14

FormControl, FormGroup, and FormArray are now strictly typed. Existing forms code may stop compiling; the migration swaps to Untyped* variants so you can adopt typing gradually.

Standalone components/directives/pipes arrive in developer preview, along with the inject() function, NgOptimizedImage (preview), functional Router guards (CanMatch), and the page Title strategy.

Angular 15 requires a current Node.js (14.20+, 16.13+, or 18.10+) and TypeScript 4.8 or 4.9.

Update the core framework and CLI together. This applies the official automatic migration schematics for this version.

ng update @angular/core@15 @angular/cli@15

Angular Material components are rebuilt on Material Design Components (MDC). DOM structure and CSS change — audit custom Material styles and run the Material migration. Legacy components are available under @angular/material/legacy-* temporarily.

bootstrapApplication, provideRouter, provideHttpClient, functional Router guards, the directive composition API, and NgOptimizedImage are all stable. Consider adopting standalone bootstrap.
