Express JS Multiple Route files not working

Question

I am using AngularJS with NodeJS as backend. I have 2 route files - route1.api.js and route2.api.js. They are used in server.js as follows:

const route1Api= require("./src/api/route1.api");
const route2Api= require("./src/api/route2.api");

app.use("/api/route1/", route1Api);
app.use("/api/route2/", route2Api);

route1.api.js and route2.api.js have similar code like the following:

const router = express.Router();
router.post("/whatever", (req, res) => {
// Code
});
module.exports = router;

I am accessing these routes from 2 different Angular data service files:

In route1.data.service.js

postRoute1() {
    console.log("Route1");
    return this._http
      .post("/api/route1/whatever", postData)
      .map(result => console.log(result));
}

In route2.data.service.js

postRoute2() {
    console.log("Route2");
    return this._http
      .post("/api/route2/whatever", postData)
      .map(result => console.log(result));
}

Now, the problem is that route1 is working fine, but route2 isn't. The postRoute2() method works only up to the console.log() line but not beyond that. What could be the problem?

route2.api.js code:

router.post("/whatever", (req, res) => {
  console.log("API hit");
  User.find({}, function(err, user) {
    if (err) res.status(500);
    if (!user) res.status(204);
    res.status(200).json(user);
  });
});

@RahulSharma No errors. "Route2" is written to the console. But the API is not getting called. — Clairvoyant, Mar 09 '18 at 06:57
try this and check are you getting response or not `app.use("/api/route2/", route1Api);` — Rahul Sharma, Mar 09 '18 at 07:01
@RahulSharma No. Still no response. The API is not being hit at all. — Clairvoyant, Mar 09 '18 at 07:11
Yes. Even if something is wrong with the returned data, it still should show "API hit" in the console, right? — Clairvoyant, Mar 09 '18 at 07:22
you are doing `module.exports = router;` right inside route2.api.js? — Rahul Sharma, Mar 09 '18 at 07:25
I moved the API code from route2.api.js to route1.api.js and accessed it from route1.data.service. Still no luck. — Clairvoyant, Mar 09 '18 at 10:38
If it was, then why doesn't it work when I wrote the same API in route1.api.js and called it? — Clairvoyant, Mar 09 '18 at 10:43
I'm not sure what's happening can you remove last / from `app.use("/api/route2", route2Api);` and try — Rahul Sharma, Mar 09 '18 at 10:46
@RahulSharma Found the issue. Used .subscribe instead of .map after the query and it works now! But why? — Clairvoyant, Mar 09 '18 at 11:13

Modify the postRoute2() method as:

postRoute2() {
    console.log("Route2");
    return this._http
      .post("/api/route2/whatever", postData)
      .subscribe(result => console.log(result));
}
