http get vue.js + node.js returns empty data

Question

I'm doing a project with vue + nativescript

the function app.get is not triggerd when I'm calling it from the vue project

this call :

const urlChannels = 'http://localhost:3001/sources';
  axios.get(urlChannels)
   .then(response => {
     store.commit('setTasks', {
       channels: response.data,
     });
   }) 
 }

returns :"data":"","status":null,"statusText":"" as if the server is off,(the call itself is valid it works with other apis)

but simple test with angularjs on the browser returns the valid needed data

this is my nodejs :

app.get('/sources', function (req, res) {
  res.set({
  'Access-Control-Allow-Origin': '*',
  'Access-Control-Allow-Methods': 'GET'
});
  res.writeHead(200,{'Content-Type':'application/json'})
  let data = getNews.getSources()
  res.send(JSON.stringify(data));
  //res.json(data); also tried this same resualt
})

Also, are you sure urlChannels has the correct url? Can you show us how that's generated? — Jim B., Oct 27 '18 at 20:38
I've tried all sorts of option before the res.end.. it is important to mention that a simple ajax call from a test request in angularjs does bring the data succesfully updated the question — Nadav, Oct 28 '18 at 09:39
I found the problem, it's a security thing with ios, they don't allow http calls, only https (I run the project on an ios emulator) — Nadav, Oct 30 '18 at 07:45

res.end() is intended for ending the response without data (see https://expressjs.com/en/api.html).

If you want to return json, the easiest way is to use res.json():

app.get('/sources', function (req, res) {
    res.set({
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Methods': 'GET'
    });
    let data = getNews.getSources()
    res.json(data);
});

The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
