connect-testab

Just a simple A/B testing middleware for connect.

Install

Usage

var connect = require('connect'),
testAB = require('connect-testab'),

    res.send('test ' + req.testAB);
});

See a full express example

By default the test will be persisted on a cookie for 7 days. You can change this value by providing a new time in milisecs.

var connect = require('connect'),
testAB = require('connect-testab'),
ONE_DAY = 24 * 60 * 60 * 1000;
app = connect();
app.use(connect.cookieParser());
app.use(testAB(ONE_DAY));
app.get('/', function(req, res){
    res.send('test ' + req.testAB);
});

If you do not want to persist it on a cookie just pass a -1

var connect = require('connect'),
testAB = require('connect-testab'),
NO_COOKIES = -1;
app = connect();
app.use(connect.cookieParser());
app.use(testAB(NO_COOKIES));
app.get('/', function(req, res){
    res.send('test ' + req.testAB);
});
