Express Versioned Routes
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. See express-request-version as a means for doing this.
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
v2, then the routers from
routes/v2/index.js would be mounted.
