I'm new to node and I'm trying to fetch the twitter id of a group of users. The module accepts an array of screen names and iterates over it to get the userId and pushes them to an array. The problem is, I can't return that array. I can access it inside the scope of the function but I can't access it outside it. I read the answers to a similar questions here and here about variable shadowing and tried it but it doesn't work.
I'm pretty sure I'm doing a dumb mistake. Can you please look at the code and help me out here?
// extractIDs.js
var Twitter = require('twitter');
var client = new Twitter({
consumer_key: process.env.TWITTER_CONSUMER_KEY,
consumer_secret: process.env.TWITTER_CONSUMER_SECRET,
access_token_key: process.env.TWITTER_TOKEN_KEY,
access_token_secret: process.env.TWITTER_TOKEN_SECRET
});
exports.getIDs = function (screenNames) {
var ids = ['something'];
for (var i = 0; i < screenNames.length; i++) {
client.get('users/show', {
screen_name: screenNames[i],
include_entities: false
}, function (error, tweets, response) {
ids.push(tweets.id);
console.log(ids) // works fine
});
}
return ids; //'something' gets returned instead of the populated ids
}
// server.js
app.post('/sendlist', bodyParser.urlencoded({
'extended': 'true'
}), function (req, res) {
res.json(extractIDs.getIDs(req.body.screen_name));
}
);
// controllers.js
.controller('testCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.printIt = function () {
console.log('stuff from controller');
$http({
method: 'POST',
url: '/sendlist',
data: {
"screen_name": ['aminspeaks', 'nodejs']
}
}).then(function successCallback(response) {
console.log('Got This response from server-- ' + response.data); // "Got This response from server-- something"
},
function errorCallback(response) {
console.log('Shit went down bro');
});
};
console.log('testCtrl is working');
}])
