Angular http get return undefined
I have a express router get
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var Stats = require('../models/Stats.js');
/* GET ALL STATS */
router.get('/', function(req, res, next) {
Stats.find(function (err, products) {
if (err) return next(err);
res.json(products);
});
});
Also api
getAll(){
this.http.get('/main').subscribe(data => {
console.log(data);
return data;
});
}
And i am using it in component
show(){
console.log(this.api.getAll());
}
Problem is that when i log data in api getAll() data is returned well, but if i log data in component i have undefined.

Your service or API within Angular should just be calling the backend service and not subscribing via in the service itself but rather in the component.
Service:
getAll(){
return this.http.get('/main');
}
Component:
this.service.getAll().subscribe((data)=> {
// Your Data
},error => {
console.log('error: ', error)
});

getAll(){
return this.http.get('/main');
}
And then in where you call the function you subscribe to the observable:
show(){
this.api.getAll().subscribe((data) => {
// Here you can do what you want with the data.
console.log(data)
})
}

And it is better to subscribe in the component part not while declaring your services.
