What problem does it solve?

Many Angular applications struggle with slow time-to-first-byte, poor SEO, and hydration mismatches when rendered purely on the client. This Skill provides patterns and configuration to run Angular v20+ on the server, produce prerendered pages, and hydrate progressively to deliver faster, SEO-friendly pages while avoiding runtime errors from browser-only APIs.

Core Features & Use Cases

  • SSR Integration: Step-by-step guidance to add @angular/ssr, bootstrap server and browser entry points, and run an Express or CommonEngine host for dynamic SSR.
  • Prerendering & Routing: Configure route renderMode options for prerender, server, or client-only routes and generate dynamic prerender params for large collections.
  • Hydration Strategies: Use provideClientHydration, incremental hydration triggers, and event replay to defer work and capture early user events.
  • Browser-only Safe Patterns: Platform detection, injected browser API tokens, afterNextRender hooks, and TransferState patterns to prevent hydration mismatches.
  • Deployment & Caching: Build outputs, server run commands, TransferState HTTP caching, CDN headers, and stale-while-revalidate strategies for production deployments.

Quick Start

Add @angular/ssr to your Angular v20+ project, configure server and browser bootstraps, set route render modes for prerendering or SSR, and enable provideClientHydration to activate hydration.

FAQPage Schema
How do I add server-side rendering to an Angular v20+ project?

To add server-side rendering to an Angular v20+ project, integrate @angular/ssr, configure separate server and browser bootstrap files, and run an Express or CommonEngine host for dynamic SSR output. This setup improves time-to-first-byte and SEO.

What is the best way to prevent hydration mismatches with browser-only APIs in Angular SSR?

To prevent hydration mismatches with browser-only APIs in Angular SSR, use platform detection checks, injected browser API tokens, afterNextRender hooks, and TransferState patterns to safely defer browser-specific initialization until after hydration completes.

How do I configure prerendering for specific routes in Angular?

Configure prerendering for specific routes in Angular by setting route renderMode options to prerender, server, or client-only, and generate dynamic prerender params for large collections to produce static HTML outputs ahead of runtime requests.

Can I use incremental hydration and event replay in Angular server-rendered apps?

Yes, you can use incremental hydration and event replay in Angular server-rendered apps by enabling provideClientHydration, configuring incremental hydration triggers to defer work, and capturing early user events for replay to maintain responsiveness.

Does Angular SSR support TransferState HTTP caching and stale-while-revalidate strategies?

Angular SSR supports TransferState HTTP caching, CDN headers, and stale-while-revalidate strategies for production deployments. These patterns cache server responses and transfer state to the client to reduce redundant API calls and improve performance.

Why do I need separate server and browser bootstraps for Angular SSR?

You need separate server and browser bootstraps for Angular SSR to isolate server execution logic from client hydration logic. This separation prevents browser-only API runtime errors on the server and ensures progressive hydration activates correctly on the client.
