A showcase of how to use three other node modules:

* replay (slightly forked)
* express
* http-proxy

Providing a way to stub out a back-end by simply running node-replay in record mode and invoking the requests that your application does or will do in the future.

npm install git+https://github.com/genesyslab/node-simulator.git

Create a server.js for all your static content (html/css/javascript etc..)

var express = require('simulator').express;

var app = express();
app.use(express.static(__dirname +'/public'));

app.listen(process.env.PORT || 3000);

Set up http-proxy to forward all api requests to your actual server.

var httpProxy = require('simulator').httpProxy

app.all('/api/*', function(req, res) {
    var proxy = new httpProxy.HttpProxy({target:{host:[YOUR_BACKEND_HOST], port:[YOUR_BACKEND_PORT]});
    proxy.proxyRequest(req, res);
});

Run in record mode to start saving responses from the server. Invoke all requests that you would like to be stubbed out.

REPLAY=record node server

Now run your stubbed out server.

node server

You will notice it is not longer making any requests directly to your backend. Instead, the fixtures are loaded.
