Set a cookie value in Node.js

Question

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

Answer 1

You could just use the response object that express provides to set your cookies.

You can find detailed information on how to do that at: http://expressjs.com/en/api.html#res.cookie

Answer 2

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.
