The Future of Angular SSR: Why It's Faster Than Ever

Angular has come a long way. With the introduction of non-destructive hydration in Angular 17, Server-Side Rendering (SSR) performance has taken a quantum leap. In this article, we break down what this means for developers and why JSL Technology is betting heavily on this tech for our clients.

Hydration is the process of 'waking up' a server-rendered application on the client-side. Historically, Angular would 'wipe' and re-render the DOM, a costly process. Now, it 'walks' the existing DOM and simply attaches event listeners, resulting in an incredibly fast Time to Interactive (TTI).
