[roadmap]: v4.0.0

[ShaunSHamilton]

Changes

• Stricten-up freecodecamp.conf.json

Features

• Tests to be written in any language
  • How to switch test runner?
    • Use codeblock language marker
    • Allow annotations like '''js,runner=python
  • Custom test runners
• Separation of client from server
  • Allow server to truly be run anywhere away from client
• Server should be a binary
  • Client-side can be inlined
  • Consider SSR for all server-side computations
• Browser test runner
  • Given a url serving a webpage, run tests in browser
    • Use websockets to send tests + results

Potentially, freecodecamp.org/learn could have a page which connects to a local freecodecamp-os server. So, the client will be publicly hosted, but the testing infra will be local.
