How do I generate JSON with ExpressJS/RailwayJS (Node.JS)
Express and Railway both extend off the HTTP module in node and both provide a "response" object as the second argument of the route/middleware handler's callback. This argument's name is usually shortened to res to save a few keystrokes.
To easily send an object as a JSON message, Express exposes the following method:
res.json({ some: "object literal" });Examples:
app.use(function (req, res, next) { res.json({ some: "object literal" });});// -- OR -- //app.get('/', function (req, res, next) { res.json({ some: "object literal" });});Check out the docs at expressjs.com and the github source is well documented as well
You just create normal JavaScript objects, for example:
var x = { test: 1, embedded: { attr1: 'attr', attr2: false }};and
JSON.stringify(x);turns it into JSON string. Note that x may contain functions which will be omitted. Also JSON.stringify returns x.toJSON() if .toJSON() is available.
