Question

I'm developing a website with node.js and express. How can I set a cookie value?

As Express is built on Connect, you can use the cookieParser middleware and req.cookies to read and res.cookie() to write cookies:

// configuration
app.use(express.cookieParser());
// or  `express.cookieParser('secret')` for signed cookies

// routing
app.get('/foo', function (req, res) {
    res.cookie('bar', 'baz');
    // ...
});

app.get('/bar', function (req, res) {
    res.send(req.cookies.bar);
});

[Update]

As of Express 4.0, Connect will no longer be included with Express and the default middleware have been moved into their own packages, including cookie-parser.
