Exploring the New Route-Level Render Mode in Angular v19 🌟

Angular v19 introduces a game-changing feature for server-side rendering (SSR) — Route-Level Render Modes. This powerful update allows you to control how each route in your application is rendered: on the server, pre-rendered during build time, or rendered on the client.

This granular control over rendering enhances performance and flexibility, particularly for dynamic web applications that need precise rendering configurations.

Why Route-Level Render Modes?

By default, Angular pre-renders (SSG) all routes without parameters and renders parameterized routes on the server. While this default setup works for many scenarios, there are use cases where you need greater control:

1️⃣ Dynamic Content: Pages like user dashboards or profiles that display personalized data should always render on the server for security and up-to-date content.
2️⃣ Frequently Changing Data: For data that updates frequently (e.g., live sports scores, stock prices, or news headlines), server rendering ensures the most current state is displayed.
3️⃣ Admin-Driven Updates: Pages where data can change dynamically, such as e-commerce product listings, need server-side rendering to reflect updates instantly.
