The web platform could really use zstd everywhere. As a content encoding for HTTP, and as an API available to JS/wasm. It's really clumsy to use a wasm version of zstd in a JS application because it's hard to get data in and out of wasm efficiently.

I'd be happy if just CompressionStream could be available as an API in all browsers already, so I could at least use gzip... Once available, I'm guessing zstd could be easier to add in later, or lz4.

Seconded this. I wanted to have a way to stream packets of some really repetitive data to javascript in the browser, and zstd-compressed json with preset dictionary really would have been the best way. Ran into a lot of problems getting zstd ports in web browser working nicely. Ended up just using a handcrafted binary format.
