Framework Briefing — Angular 17 Adds Built-in Control Flow
Angular 17 launched on 8 November 2023 with built-in control flow, deferrable views, and a Vite-powered build system, prompting front-end teams to align templates, SSR pipelines, and tooling.
Executive briefing: Google released Angular 17 on , introducing the most significant template and tooling changes since standalone components.
Feature highlights
- Built-in control flow. New
@if,@for, and@switchsyntax replaces structural directives with faster compiled output. - Deferrable views. Template annotations enable fine-grained lazy loading without bespoke routing code.
- Vite and esbuild pipeline. The CLI defaults to a faster dev server and build stack, reducing rebuild times.
- Improved SSR. Enhanced hydration and partial rendering streamline Angular Universal deployments.
Adoption steps
- Upgrade shared libraries to Angular 17 to unblock consumers from adopting the new template syntax.
- Refactor templates incrementally to the control flow syntax while retaining directive fallbacks where necessary.
- Benchmark the Vite-based builder in CI/CD and document migration steps for custom webpack configurations.
