Spotify API Getting all tracks at once
I am trying to do a web app that uses the Spotify API (using node.js as server) but I've recently come across a problem I can't solve. Basically, I want to compare the content of two playlists but since the API only gives 100 tracks per request, I can't find a way to get this done. I already tried to use loops inside requests but I doesn't seem to work.
request.get(options, function(error, response, body) {
var data = ;
data.push(JSON.parse(JSON.stringify(body)));
let urls = ;
for (let i = 0; i < data[0].total; i = i + data[0].limit){
urls.push('https://api.spotify.com/v1/me/tracks?offset='+i);
}
data = ;
for (let i = 0; i < urls.length; i++) {
options.url = urls[i];
request.get(options, function(error, response, body) {
let tmp = JSON.parse(JSON.stringify(body));
let items = tmp.items
if (items != null){
for(let o of tmp.items) {
data.push(o.track.name);
}
if (tmp.next == null){
return res.send(JSON.stringify(data));
console.log('done');
}
}
});
}

You could use recursion to get all tracks in a playlist.
You could have a method that gets the playlist page then loop call it until you don't have any more tracks to retrieve. Just as an example, here is a possible solution in pseudo code. I've written this quickly so forgive any bugs...
function getplaylisttracks(playlistid, pagesize,offset) {
//call 'get tracks' api with pagesize and offset
//return response
}
var offset = 0;
var pagesize = 100;
var continueloop = true;
var result = getplaylisttracks(YOURID, pagesize, offset);
do {
try {
//*** process result tracks into your array here ***
if(result.next!=null) {
offset = offset+pagesize;
result = getplaylisttracks(YOURID, pagesize, offset);
}
else {
continueloop = false;
}
}
catch(e) {
//handle error here...
continueloop = false;
}
}
while(continueloop);
Once you have all the tracks for each playlist you could run a comparison
