How to call another api via express?

My goal is to put http://localhost:3000/test into my browser and get the response from http://my_virtual_machine:8080/rest/stuff/test.

I followed this tutorial to setup Express, mongoose (although the final version of this will not connect to Mongo, only the VM's endpoints), etc. I produced a to-do list API, and it works as expected.

However, I can't figure out how to call my VM with this API.

I read "External API Calls With Express, Node.JS and Require Module", and came up with the following addition to server.js:

router = express.Router(),
request = require('request');

router.get("/test", function(req,res,next){
    request({
        uri: 'http://my_virtual_machine:8080/rest/stuff/test/',
    }).pipe(res)
})

But, when I put http://localhost:3000/test into my browser I get a 404 error in the console.

Here's a PLUNK of all my code. server.js contains the changes I have made to try to get this to work.

I'm an Express noob, so I'm not sure why this doesn't work.

You need to add the router to the express app instance. This can be done using

app.use('/test', router);

The above line tells express to route all requests to /test to your router instance.

And inside your router, since you already specified the path, you should change the get function to

router.get('/', function(req, res, next) {
     request({
         uri: 'http://my_virtual_machine:8080/rest/stuff/test/',
     }).pipe(res)
});
