express-routes-versioning/examples/example1.js

Node.js module provides versioning for expressjs routes/api

var app = require('express')();
var routesVersioning = require('../index')();
app.listen(3000);

app.get('/test', routesVersioning({
   "1.0.0": respondV1,
   "~2.2.1": respondV2,
   "2.5.0": respondV3
}));


//curl -s -H 'accept-version: 1.0.0' localhost:3000/test
// version 1.0.0 or 1.0 or 1 !
function respondV1(req, res, next) {
   res.status(200).send('ok v1');
}

//curl -s -H 'accept-version: 2.2.0' localhost:3000/test
//Anything from 2.2.0 to 2.2.9
function respondV2(req, res, next) {
   res.status(200).send('ok v2');
}

//curl -s -H 'accept-version: 2.5.0' localhost:3000/test
//curl -s -H 'accept-version: 3.0.0' localhost:3000/test
// If client version doesn't match any provided server versions (eg: 3.0.0), then latest
 // version callback is called by default (if NoMatchFoundCallback is not found)
function respondV3(req, res, next) {
    res.status(200).send('ok v3');
}
