Build for WASM - Githubissues

amaury1093 commented 4 years ago

What does it take to make this lib compile to WASM?

Rationale: since browsers allow TCP connections, this should work in browser. I'd also like to try deploying this to cloudfare workers.

Right now, some deps don't compile to WASM, running wasm-pack build in core/ gives:

Being able to call this library from a server side node or deno codebase as a wasm library would be great.

For server-side node code, there's also an alternative: #1105
