使用具有多个URL和可选参数的express.Router（）

Question

I am having trouble using express.Router() the way I wan to and am not sure what my issue is. My problem is that when I make a GET request to the url '/api/zip' or to '/api/zip/' + zip, where zip is a numerical zip code, the only route that gets hit is '/', which in the example below logs '$$$$$$$$$$$$'.

When I take out the route for '/' in results_api.js, 'made it to server.js' gets logged, but I don't get anything from results_api.js. Let me know if I need to post more context code. I am using an Angular front end, but I am assuming that since my request always gets to server.js (verified by 'made it to server.js' being logged), that my problem is within results_api.js.

I have used this routing method before and am not sure what is going wrong this time around. How do I manage to hit routes.get('/zip/:zip... ?

In my server.js file:

var express = require('express');
var routes = express.Router();

//route to index.html
var assetFolder = Path.resolve(__dirname, '../client/');
routes.use(express.static(assetFolder));

//api routes
routes.use('/api/*', require(‘./api/results_api.js’), function(){ 
console.log('made it to server.js')});

My results_api.js file:

var router = require('express').Router();

router.get('/', function(req, res){
  console.log('$$$$$$$$$$$$$$$')

}); 

router.get('/zip', function(req, res){
  console.log(‘###################’)

}); 

router.get('/zip/:zip', function(req, res){
  console.log('%%%%%%%%%%%%%%%%%')

}); 

module.exports = router;

This question:

express.Router() get url route with optional parameters

Is close to mine, but there is no intermediate parameter ( in my case '/zip/' after '/api'). Is this indicative of what I am trying to do just being the wrong way to go about building my api?

Call these handlers in reverse order. /zip/:zip , then /zip , then / .

Actually, the problem is this line:

routes.use('/api/*', require(‘./api/results_api.js’), function(){ 
console.log('made it to server.js')});

/api/* will "gobble up" anything after /api/ , so your router will think it is called with / . Change this to:

routes.use('/api', require('./api/results_api.js'), function() { 
    console.log('made it to server.js')
});
