SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Provides a structured approach to add server-side rendering, hydration, and prerendering to Angular v20+ projects so pages render quickly for users and search engines while avoiding hydration mismatches and browser-only runtime errors.

Core Features & Use Cases

  • SSR Setup: Guide to add @angular/ssr, create server bootstrap files, and update angular.json for server and browser builds.
  • Hydration Strategies: Instructions for default hydration, incremental hydration triggers, and event replay to capture pre-hydration interactions.
  • Prerendering & Caching: Techniques to prerender static routes, generate dynamic prerender params, use TransferState for HTTP caching, and configure HTTP/CDN caching headers.
  • Browser-only Compatibility: Patterns for platform detection, safe injection of window/localStorage, and using afterNextRender to run DOM-only code.

Quick Start

Add SSR to your Angular v20+ app, configure prerender routes and enable client hydration with event replay for interactive components.

Frequently Asked Questions about angular-ssr

High-intent search queries and answers about installing and using this skill.

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

To add server-side rendering to Angular v20+, configure @angular/ssr by creating server bootstrap files and updating angular.json for server and browser builds to produce SEO-friendly pre-rendered HTML.

How does hydration work in Angular to prevent mismatches?▼

Angular hydration works by attaching event listeners to pre-rendered HTML without re-rendering the DOM, using strategies like incremental hydration triggers and event replay to capture pre-hydration interactions and avoid mismatches.

What is the best way to prerender static routes and cache HTTP requests in Angular?▼

The best way to prerender static routes in Angular is generating dynamic prerender params while using TransferState for HTTP transfer caching and configuring HTTP/CDN caching headers.

How to safely use browser-only APIs like localStorage during Angular SSR?▼

Safely use browser-only APIs during Angular SSR by implementing platform detection, performing safe injection of window/localStorage, and using afterNextRender to run DOM-only code on the client.

Can I configure incremental hydration for specific Angular components?▼

Yes, you can configure incremental hydration in Angular v20+ by setting specific hydration triggers and implementing event replay to capture interactions for interactive components before they fully hydrate.

Why do I need TransferState in an Angular server-side rendered application?▼

You need TransferState in an Angular SSR application to transfer server-fetched data to the client, enabling HTTP transfer caching that prevents duplicate API requests during client-side hydration.
