There is already a Connect Middleware for Timeout support: var timeout = express.timeout // express v3 and below var timeout = require(‘connect-timeout’); //express v4 app.use(timeout(120000)); app.use(haltOnTimedout); function haltOnTimedout(req, res, next){ if (!req.timedout) next(); } If you plan on using the Timeout middleware as a top-level middleware like above, the haltOnTimedOut middleware needs to be the … Read more
The comparison is not entirely correct. The difference between node.js and express.js in the level of abstraction: Node.js is a run-time environment for building server-side event-driven i/o application using javascript. Express.js is a framework based on node.js for building web-application using principles and approaches of node.js So, if you write web-application, you can try to … Read more

This is explained in detail in the express behind the proxies guide By enabling the “trust proxy” setting via app.enable(‘trust proxy’), Express will have knowledge that it’s sitting behind a proxy and that the X-Forwarded-* header fields may be trusted, which otherwise may be easily spoofed. Enabling this setting has several subtle effects. The first … Read more
app.get(‘/fruit/:fruitName/:fruitColor’, function(req, res) { var data = { “fruit”: { “apple”: req.params.fruitName, “color”: req.params.fruitColor } }; send.json(data); }); If that doesn’t work, try using console.log(req.params) to see what it is giving you.
Here is how you can add Socket.io to a newly generated Express-Generator application: Create a file that will contain your socket.io logic, for example socketapi.js: socketapi.js: const io = require( “socket.io” )(); const socketapi = { io: io }; // Add your socket.io logic here! io.on( “connection”, function( socket ) { console.log( “A user connected” … Read more
If you using the node-mysql module, just remove the .connect and .end. Just solved the problem myself. Apparently they pushed in unnecessary code in their last iteration that is also bugged. You don’t need to connect if you have already ran the createConnection call
You can specify which .env file path to use via the path option with something like this: require(‘dotenv’).config({ path: `.env.${process.env.NODE_ENV}` })
Express 4.x Updated Answer Session handling is no longer built into Express.

It says: Destroys the session, removing req.session, will be re-generated next request. req.session.destroy(function(err) { // cannot access session … Read more
BufferList is obsolete, as its functionality is now in Node core. The only tricky part here is setting request not to use any encoding: var request = require(‘request’).defaults({ encoding: null }); request.get(‘http://tinypng.org/images/example-shrunk-8cadd4c7.png’, function (error, response, body) { if (!error && response.statusCode == 200) { data = “data:” + response.headers[“content-type”] + “;base64,” + Buffer.from(body).toString(‘base64’); console.log(data); } … Read more
