:computer: Pop-up JavaScript challenges in your browser

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.

challenger's Issues

Typing `function` kills the page

Steps to reproduce:

1. open one of the demos at http://rileyjshaw.com/challenger
2. type function
3. oops...

Link offsets on demo page are funky

Use the force...

Line comments in code blocks break

Test case:

if (1) {
  // here's our line comment
}

verify('should work...');

Removing the line comment makes verify pass...

demo/**/main.js missing after gulp build

entry: './demo/src/scripts/main.js',

http://localhost:8000/ <- Cannot GET /

code evaluation not correct (fizzbuzz)

function fizzbuzz (n) {
var fizz = (n % 3 == 0) ? 'Fizz' : null
var buzz = (n % 5 == 0) ? "Buzz" : null
return [fizz, buzz].join('')
}

That is a valid fizzbuzz yet your project says no
