path-prefix-proxy v1.1.0

path-prefix-proxy

path-prefix-proxy is an express middlewhere which makes it easy to add a prefix path your existing express app.

The most common use case for this is when you have different services running on different express servers, but you have something like nginx proxying all of these services to a single hostname.

For example, say you have an app that currently has the routes

GET /login
POST /login
GET /logout

But you've realised you want to share the host with some other services. So you'd like to prefix all of these paths with /auth, going to:

GET /auth/login
POST /auth/login
GET /auth/logout

And what if you need these to be configurable? What if you have static resources that you want to be nested under /auth as well? path-prefix-proxy to the rescue!

Usage

Just add this middleware to your express app like so:

var pathPrefix = '/auth';
app.use(pathPrefix, require('path-prefix-proxy')(pathPrefix));

and immediately your old routes will begin working in their new locations too!

Install

npm install path-prefix-proxy
