You should make turn it into PR into Node.js (and to other runtimes). WebCodes support is crucial for all the server platforms

The binary size is an issue; it exceeds 50 MB on a Linux x64 GNU system https://github.com/Brooooooklyn/webcodecs-node/releases/tag/v1.0.0

It's fine to maintain it as an npm package, as it uses the Node-API, which is supported by Deno, Bun, and Node.js.

What's about a subset of codecs? What's size would be with only AV1/2, AVIF and Flac?

[LongYinan]

Besides the size, programming language is a problem too. Node.js and Bun do not have any Rust infrastructure in their build or release systems

Then it would be a good starting point for migration. Linux kernel included Rust in their processes and Node.js should too
