Chisel in the Browser

Idea from https://twitter.com/bradfitz/status/1451423386777751561

• Build a WASM version of chisel
• Instantiate the chisel.Client in the browser (chisel works over binary web sockets, the client will work natively in a browser)
• Build chisel client UI
  • Enter server
  • Enter auth / fingerprint
  • Open X remotes
  • Take any of Y actions on these remotes
• Actions must operate on top of TCP (binary streams)
• Action ideas:
  • Web client on http remotes (browse and render, intercept requests, make outbound requests with net/http as the HTTP client)
  • SSH client on ssh remotes (crypto/ssh SSH client, xterm to render terminal, similar to gotty)
  • VNC client using noVNC (this library already has a binary interface)
  • And more
• Statically hosted (pure JS, no server required to run the client)

Start by examining the chisel.Client and its binary WebSocket behavior, then determine how a WASM build can instantiate it in a browser. The scope includes a statically hosted client UI for server and authentication input, remote selection, and TCP-based actions such as HTTP, SSH, or VNC. Done would require a working pure-JavaScript browser client with at least a defined set of supported actions.
