    text
    copied!<p>I'm writing an API using Node.js and Express. My API has GET methods of the form:</p> <pre><code>/api/v1/doSomething /api/v1/doSomethingElse </code></pre> <p>My code is looking something like this:</p> <h2>server.js:</h2> <pre><code>var app = express(); ... var routes = require('./routes') routes.attachHandlers(app, '/api/v1') </code></pre> <h2>routes/index.js</h2> <pre><code>... module.exports.attachHandlers = function(app, context) { //get a list of all the other .js files in routes //for each route, require() it and call it myRoute myRoute.attachHandlers(app, context) } </code></pre> <h2>routes/some-route.js</h2> <pre><code>... module.exports.attachHandlers = function(app, context) { app.get(context + '/doSomething', doSomething) app.get(context + '/doSomethingElse', doSomethingElse) } ... </code></pre> <p>Effectively I'm passing the context path/mount point down through the app. If somebody were to write a route like the following, though, the context would be lost:</p> <pre><code>app.get('/doFoo', foo) </code></pre> <p>Rather than having that part of the API mounted on <code>/api/v1/doFoo</code> it's on <code>/doFoo</code>. I would like to avoid having to pass the context path around like this.</p> <p><a href="http://expressjs.com/api.html#app.use" rel="noreferrer">app.use</a> supports mounting middleware on an optional mount path. I have seen references online to mounting an entire Express application on a mount path using <code>app.use</code>. This seems like the sort of thing I want to do, but I'm not sure how to do it or if it's the best solution for my particular use case.</p> <p>To summarise - I want to mount my app.get() routes with a particular prefix by default. What's the best way of doing this?</p>
