Challenger v1.0.2

Pop-up JavaScript challenges in your browser

Challenger is a drop-in JavaScript library that adds interactive programming challenges to any page. Challenges are flexible and expressive, and are super simple to write.

A challenge has requirements based on code structure and program output, and gives users a code editor to experiment in. When new code is written, it's run in a sandbox and the output is analyzed.

Challenges can be presented as one-off tests or linked together to form courses.

Roadmap

  • Multiple challenges in a row
  • Custom rules
  • Styling
  • Code evaluation on the client
  • Code evaluation on the server
  • Add setup and teardown options to challenge objects
  • Fix CodeMirror rendering in older versions of Firefox
  • Reduce the bundle size

Reducing bundle size important, as we're currently weighing in at ~2M. There's a lot of bloat from redundant dependencies - if anyone has experience with this I'd really appreciate a hand.

Browser support

Tested with BrowserStack

  • Chrome 18+
  • Firefox 9+
  • Opera 15+
  • Safari 5.1+
  • IE9+
  • Mobile Safari

If you need to support older browsers, include krisowal's es5-shim along with es5-sham.js from the same repository. You might also need to tweak the CSS.
