In a Nutshell. Sending a response in Express with a call like res.send(status, body) will send body as the status code if it is numeric - ignoring status. This is due to a fudge for backwards compatibility. The Details. As part of a project Im working on, Im writing a service using node.js and Express. Express is today the de-facto primary framework for use with Node.js. With much reason indeed.The only real difference is that we send back a JSON object as the response of the get() method. Lets break it down. At the top we again require express, and create an app object.

That response is a string too, if you want to send the response prettified, for some awkward reason, you could use something like JSON.stringify(anObject, null, 3).
Its important that you set the Content-Type header to application/json, too. In example 1, we have imported the Node.js modules we need. The Express module takes care of the heavy lifting with regards to fulfilling web requests. If you are not familiar with the Express Node.js module, please see my earlier blog post on this subject The first 2 lines import express node module and create an express app instance.sudo npm install express sudo npm install basic-auth node app.js. To make the get request from a browser, just go to the url localhost:3030/auth. Node.js Foundation. BlockedUnblock.
