Research direction
The issue requests implementing the Direct Sockets API (explainer linked) in Emscripten to allow network sockets in browsers without a proxy. Currently, no assignee or PR exists. To start, review the spec and understand the existing socket implementation in library sockfs.js. Consider how to expose the API to compiled code. There are 5 comments, but no maintainer response clarifying scope, so investigation into the spec and existing issues is needed.
