Node.js and express - how to read a cookie but is undefined

Question

I use the below to set a cookie using express. ``` res.cookie('test', 'yes', { expires: new Date(Date.now() + 365*2*24*60*60*1000), httpOnly: true }); ``` I am using the middleware to try and read the cookie: ``` app.use(express.cookieParser()); var cookie_id = req.cookies.test; ``` Problem is that cookie_id is undefined whne it would be 'yes' ``` Express server listening on port 8060 in development mode TypeError: Cannot read property 'test' of undefined at /home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbNodejsServer/nodeServer/app.js:48:29 at callbacks (/home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbNodejsServer/nodeServer/node_modules/express/lib/router/index.js:272:11) at param (/home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbNodejsServer/nodeServer/node_modules/express/lib/router/index.js:246:11) at pass (/home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbNodejsServer/nodeServer/node_modules/express/lib/router/index.js:253:5) at Router._dispatch (/home/ubuntu/workspace/rtbo…

Accepted Answer

You need to use `express.cookieParser()` before `app.router`; middleware is run in order, meaning it's never even reaching `cookieParser()` before your route is executed.

Try this:

```
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
```
