Asynchronous method in while loop with Graph API paged

Question

I\'m using facebook node sdk for node.js to get information from a facebook user such as their feed and friends, which is working fine.

However I\'m having an issue wher

Answer 1

My idea of solving this with async/await:

async function getFeed(token) {
    let feedItems = [],
        hasNext = true,
        apiCall = '/me/feed';

    while (hasNext) {
        await new Promise(resolve => {
            FB.api(apiCall, {access_token: token}, (response) => {
                feedItems.concat(response.data);
                if (!response.paging.next) {
                    hasNext = false;
                } else {
                    apiCall = response.paging.next;
                }
                resolve();
            });
        });
    }
    return feedItems;
}

getFeed().then((response) => {
    console.log(response);
});

Be aware that you need Node.js 7.9.0+ for this: http://node.green/

For older versions, install this: https://github.com/yortus/asyncawait

You can also use a recursive function, but the smooth/modern way would be async/await.

Answer 2

Instead of using:

feedItems.concat(response.data);

I have made: (if is the case on response.data has the data)

for(var i in response.data){
   feedItems.push(response.data[i]);
}
