Angular 20: SSR vs CSR vs Pre-rendering - A Deep Dive

Описание: Understanding rendering strategies in Angular is crucial for building high-performance, SEO-friendly web applications. In this in-depth guide, we) break down Server-Side Rendering (SSR), Client-Side Rendering (CSR), Pre-rendering (Static Site Generation - SSG like), and the role of Hydration in Angular v20.

Discover the differences, benefits, and practical implementation of each rendering mode. Learn how to set up an Angular v20 project with SSR, explore the key configuration files, and see live demonstrations of how renderMode (Server, Client, Prerender) impacts your application's behavior and output.

This video is perfect for developers looking to make informed decisions about their Angular app's architecture.
Get ready to optimize your Angular applications for speed and discoverability!

Key Topics Covered:
👉What is Server-Side Rendering (SSR)?
👉Benefits of SSR: Faster First-Paint, SEO & Social Previews, Predictable Data Fetching.
👉SSR Flow Diagram Explained.
👉Client-Side Rendering (CSR) vs. SSR: Conceptual Differences.
👉CSR vs. SSR: Timeline Comparison.
👉Creating a new Angular v20 application with SSR enabled (ng new --ssr).
👉Exploring SSR-related files: angular.json, server.ts, package.json scripts, app.routes.server.ts.
👉Building and Running an SSR application (ng build & npm run serve:ssr:[app-name]).
👉Comparing SSR build with ng serve (development server).
👉Understanding renderMode options in app.routes.server.ts:
👉RenderMode.Server (SSR on demand)
👉RenderMode.Client (CSR)
👉RenderMode.Prerender (SSG-like, at build time)
👉Demonstrating rendering differences using console.log (server vs. client execution).
