web-rs

Rust bindings to make WASM more tolerable.

Unstable API

Some crates use unstable web_sys APIs and you may need to set --cfg=web_sys_unstable_apis when compiling. For more information, see the web-sys docs.

There's a few ways to set this depending on the environment:

web-codecs

web-codecs provides a wrapper around the WebCodecs API.

The callbacks have been replaced with a channel-like API. For example, the VideoEncoder is split into a VideoEncoder for input and a VideoEncoded for output.

web-streams

web-streams provides a wrapper around the Streams API.

This API is annoyingly untyped when using web_sys. This library handles the casting for you as well as providing guard-rails around the API (ex. closing on Drop).
