facebook graph api

Setup a Node.js Facebook Social Graph API data extractor This job consist of two tasks Scope how to access / retrieve the secret keys / private tokens needed for pulling this data Write the query urls needed for fetching the scoped data from the facebook graph API. If possible we should fetch all the data in one api call, if this is not possible then we should combine multiple API calls to retrieve the full data as scoped: I started formulating a query string, but this url only fetch some of the data needed {page-id}?fields=engagement,name,fan_count,rating_count,likes,posts,checkins Next build a simple nodejs “data pull” and expose an api endpoint for executing the “data pull” When the full api is done, I should able to call the nodejs “data pull” api like so localhost:5000/api/%%fbPageId%% And then the API should fetch the data from the facebook social graph API, and write it into a JSON obj formatted like follows, and then return it to the initial api requester { pageId: %%pageid%%, fans_total: %%number%%, fans_monthly_numeric_growth: %%number%%, fans_monthly_pct_growth: %%number%%, pageviews_total: %%number%%, pageviews_unique: %%number%%, checkins: %%number%%, reach_unique: %%number%%, organic_unique: %%number%%, paid_unique: %%number%%, engagement_rate: %%number%%, posts_total: %%number%%, organic_posts: %%number%%, sponsored_posts: %%number%%, sponsored_spend: %%number%%, ads_total: %%number%%, ads_spend: %%number%% } Please use as few dependencies and nmp frameworks a possible! :) Please comment and write many notes in the nodejs code, explaining how the code works, and why it is written as it is
