Currently in development of my MEAN app, the client-side sends a $http POST request to my API with a JSON array containing soundcloud track data specific to each user. My goal now is to save these tracks to my app database within a 'tracks' table. This will allow me to load the tracks for the user from the database and also create unique client URLs like (/tracks/:track)
Here is some sample data:
{
artist: "Nicole Moudaber"
artwork: "https://i1.sndcdn.com/artworks-000087731284-gevxfm-large.jpg?e76cf77"
source: "soundcloud"
stream: "https://api.soundcloud.com/tracks/162626499/stream.mp3?client_id=7d7e31b7e9ae5dc73586fcd143574550"
title: "In The MOOD - Episode 14"
}
This data is sent to the API as follows:
app.post('/tracks/add/new', function (req, res) {
var newTrack;
for (var i = 0; i < req.body.length; i++) {
newTrack = new tracksTable({
for_user: req.user._id,
title: req.body[i].title,
artist: req.body[i].artist,
artwork: req.body[i].artwork,
source: req.body[i].source,
stream: req.body[i].stream
});
tracksTable.find({'for_user': req.user._id, stream: req.body[i].stream}, function (err, trackTableData) {
if (err)
console.log('MongoDB Error: ' + err);
// stuck here - read below
});
}
});
I'm currently facing a challenge at this point, as mentioned above: I need to check if the track already exists in the database for that particular user, and if not, then save it. Once all tracks have been processed, either saved or ignored, a 200 response should be sent back to the client.
I've tried various approaches but haven't had success yet. Any help or advice on this matter would be greatly appreciated.
