Prerendering the next page before a user clicks can make navigation feel instant — and the Speculation Rules API makes it a few lines of markup. Here's how eagerness, limits, and bfcache fit together, with real numbers from a production rollout.
Chrome 151 adds a textStream() method to Response, Request, and Blob — a small addition that removes the TextDecoderStream boilerplate from every streaming-text handler you write, from LLM token streams to progressive HTML.
