Astro Framework Migration:
Achieving 100% HTML Pre-Rendering
Following the indexing challenges identified in Solution A, we implemented a full-scale framework upgrade to Astro.
The Challenge
While Solution A addressed the immediate indexing "leak," the underlying issue remained: the client's previous framework was heavily dependent on client-side JavaScript. This made every new page a potential SEO risk and slowed down mobile performance significantly. We needed a solution that would pre-render every URL as static HTML by default.
The Solution
We selected Astro as the target framework. Its "Island Architecture" allowed us to keep the interactive features of the previous site while ensuring that the actual content was delivered as pure, pre-rendered HTML.
- ✦Framework Selection: Evaluated Next.js vs. Astro, choosing Astro for its superior zero-JS-by-default performance.
- ✦Full HTML Pre-rendering: Configured the build process to output static HTML for all pages, including dynamic routes.
- ✦Component Migration: Converted legacy React/Vue components into Astro components where interactivity wasn't required, slashing bundle size.
