Try it out!

Go to https://tbfleming.github.io/em-shell/

Current status

• Runs on Chrome and Firefox
• Some built-in commands work
• Some vfork-exec commands work
• Gets confused when the terminal page has more than 1 tab or window opened on it

How it works

• busybox compiled by emscripten
  • Doesn't use Emterpreter or Asyncify!
• busybox processes run in web workers
• The web workers communicate with the UI through a service worker
• The web workers use synchronous (blocking) XMLHttpRequest to wait for terminal input
