Have you ever wanted to quickly test a new performance idea, or see if the latest performance wisdom is beneficial to your site? As web performance appears to be a stochastic process, it is really important to be able to iterate quickly and review the effects of different experiments.
The second blog post in the series on HTML rewriters picks up the story in 2017 after the launch of the Cloudflare edge compute platform Cloudflare Workers. It became clear that the developers using workers wanted the same HTML rewriting capabilities that we used internally,
To coincide with the launch of streaming HTML rewriting functionality for Cloudflare Workers we are open sourcing the Rust HTML rewriter (LOL HTML) used to back the Workers HTMLRewriter API. We also thought it was about time to review the history of HTML rewriting at Cloudflare.
HTMLRewriter helps solve big problems web developers face today: making changes to the HTML at the server level, and making it possible for HTML to live on the edge— without sacrificing functionality.
Today, we’re excited to announce HTMLRewriter beta — a streaming HTML parser with an easy to use selector based JavaScript API for DOM manipulation, available in the Cloudflare Workers runtime.
