Not so static... Introducing the HTMLRewriter API Beta to Cloudflare Workers

What this post added

Introduced the HTMLRewriter API beta for Cloudflare Workers, enabling streaming HTML parsing and DOM manipulation with a jQuery-like JavaScript API. This allows for dynamic transformations of static HTML content directly on the edge, complementing Workers Sites and enabling JAMstack architectures with edge-side rendering. The API addresses limitations of previous methods that ingested entire response bodies, which impacted TTFB and prevented streaming.
