This middleware allows express routes to be mounted by version and provides a method to route between version paths and accept headers. The latter is based on the assumption that a version property will exist on the request object.
This middleware will mount paths from a directory that match the supported versions
you specify. Each mounted directory's index.js should return either a router or valid
middleware. For example, if the middleware is used with the base path routes and
supported versions v1, v2, then the routers from routes/v1/index.js and
routes/v2/index.js would be mounted.
var versionRoutes = require('express-versioned-routes');
app.use('/', versionRoutes(
path.join(__dirname, 'routes'),
['v1', 'v1.1', 'v2']
