As Facebook has discontinued the FQL query API for all apps created after 2014-04-30, it has gotten much more complicated to get public Facebook events by passing a location.
This implementation uses regular Facebook Graph API calls in a three-step approach to get the events:
- Search for Places in the radius of the passed coordinate and distance (
/search?type=place&q={query}¢er={coordinate}&distance={distance}). This returns Page objects. - Use the returned Place Page objects to query for their events in parallel (
/?ids={id1},{id2},{id3},...) - Unify, filter and sort the results from the parallel calls and return them to the client
- The Graph API has some "instabilities" with search results. It's possible that the amount of results returned can vary between calls within seconds
- The
/searchendpoint "magically" limits the number of results, independent from thedistanceused (larger distance doesn't guarantee more results) - Rate limiting will apply, but I experienced no call blocks within a reasonable amount of service requests. Be aware that the way this application works, there are potentially hundreds of (counted) Graph API calls per request to
/events.
The module can be installed via
npm install facebook-events-by-location-core --save
To clone the repository, use
git clone https://github.com/tobilg/facebook-events-by-location-core.git
The basic usage pattern of this module is the following:
var EventSearch = require("facebook-events-by-location-core");
var es = new EventSearch();
es.search({
"lat": 40.710803,
"lng": -73.964040
}).then(function (events) {
console.log(JSON.stringify(events));
}).catch(function (error) {
console.error(JSON.stringify(error));
});The above example expects that the FEBL_ACCESS_TOKEN environment variable is set to a valid App Access Token. Otherwise, you need to specify the accessToken parameter with the request.
Mandatory parameters are the following:
lat: The latitude of the position/coordinate the events shall be returned forlng: The longitude of the position/coordinate the events shall be returned for
Non-mandatory parameters
query: The term(s) on which you want to narrow down your location search (this only filters the places, not the events itself!).categories: The array of place categories that should be searched for. Valid entries areARTS_ENTERTAINMENT,EDUCATION,FITNESS_RECREATION,FOOD_BEVERAGE,HOTEL_LODGING,MEDICAL_HEALTH,SHOPPING_RETAIL,TRAVEL_TRANSPORTATION. Default is none.accessToken: The App Access Token to be used for the requests to the Graph API.distance: The distance in meters (it makes sense to use smaller distances, like max. 2500). Default is100.sort: The results can be sorted bytime,distance,venueorpopularity. If omitted, the events will be returned in the order they were received from the Graph API.version: The version of the Graph API to use. Default isv2.10.since: The start of the range to filter results. Format is Unix timestamp orstrtotimedata value, as accepted by FB Graph API.until: The end of the range to filter results.
There are two types of locations in the resulting event JSON objects:
place: This is the consolidated Place object from the Venue (which is actually the Page object which was returned from the Place search), and the Event's place data. The latter will supersede the Place page data.venue.location: This is the location data of the Page object.
As the Facebook Graph API can only be queried for Places via coordinate/distance, and Events can have their own, "real" location, it's possible that the place data which is found in place can be outside the boundaries of the original query.
Consequences:
- If you want consistency regarding query vs. results, you should use
venue.location. - If you want accuracy regarding the real event location, you should use
place.
