    Connect / Express middleware that causes chaos

    This is loosely inspired by chaos monkey. The basic idea is that you can drop it into your connect / express app and see how your clients get on when things go wrong. You might want to have it enabled by an environment variable so you can switch it on and off easily.

    Installation

    $ npm install connect-chaos

    Usage

    var chaos = require('connect-chaos');
     
    // anything can happen
    app.use(chaos());
     
    // requests might be delayed by 2000ms (default)
    app.use(chaos({
      delay: true
    });
     
    // requests might be delayed by specified value
    app.use(chaos({
      delay: 300
    });
     
    // requests might return an error code
    // Client error codes: 400, 401, 402, 403, 404, 405, 406, 407, 407, 409, 410, 411, 412, 413, 414, 415, 416, 417

    app.use(chaos({

    });
     
    // requests might return specified code
    app.use(chaos({
      error: 401
    });

    app.use(chaos({
      error: [404, 500]
    }));
     
    // requests might return a code that matches the regex
    app.use(chaos(){
      error: /^40/
    });
