Can Google Index JavaScript Websites? Yes, With Caveats
How Googlebot processes JavaScript, from Google's own documentation.
1 min read
Summary
Yes, Google can index JavaScript websites: Googlebot processes JavaScript apps in three phases, crawling, rendering and indexing. Rendering can happen later than crawling, so server-side or static rendering still makes content available faster and more reliably.
How Google processes JavaScript
Googlebot fetches the URL, queues the page for rendering in a headless Chromium, then indexes the rendered HTML. Links found during processing go back into the crawl queue.
Common problems
- Links built with click handlers instead of
<a href>elements - Error pages that return 200, which become soft 404s
- Content blocked by robots.txt rules on JS or API files
Recommendations
Use real links, meaningful status codes and unique titles per page. Server-side rendering, static generation or hydration help both users and crawlers. Google describes dynamic rendering as a workaround, not a long-term solution.

Is typescript-eslint Strict Worth 4x Errors?
We ran three typescript-eslint presets on a real open-source TypeScript library and counted every finding and second. The jump to strict was smaller than the jump to type-aware linting, and the findings themselves tell you whether your team is ready.
