Send data from ExpressJS to AngularJS ERROR json

Question

i have a problem when i want send data from Express to Angular I get error:

SynatxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

File: controller.client.js

$scope.getData = function() {
        $http.get('http://localhost:3000/getData').then(function(response) {
            alert('good: ');
            console.log(JSON.parse(response));
        }, function(error) {
            alert('Error: ');
            console.log("error: ");
            console.log(error);
        });
    }

File: server.controller.js

exports.getData = function(req, res) {
    var data = {
        "name": "kacper",
        "age": 12
    };
    console.log('getData function: ');
    console.log(data);

    res.json(data);
}

File server.routes.js

app.get('/getData', index.getData);

and always in my response is error:

SynatxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

how to fix that?

there is no need to use JSON.parse inside $http.get success, it will already be a well formed JSON, refer this answer — Pankaj Parkar

From your server you are sending your response by res.json(data).

res.json() Sends a JSON response. When angular gets that response it's already a JSON. You don't need to parse it again. Use it as is.
