I need to get my priority range data, for example, using startAt / endAt in JS, but in REST. Is it possible?
I believe this is now possible using beta API requests.
According to https://www.firebase.com/docs/beta/queries/rest.html :
The startAt parameter accepts any type that you specify in orderBy. This query finds all dinosaurs at least 3 meters high.curl 'https://dinosaur-facts.firebaseio.com/.json?orderBy="height"&startAt=3' And this query finds all dinosaurs, starting with Stegosaurus. curl 'https://dinosaur-facts.firebaseio.com/.json?orderBy="$key"&startAt="stegosaurus"'
The startAt parameter accepts any type that you specify in orderBy. This query finds all dinosaurs at least 3 meters high.
curl 'https://dinosaur-facts.firebaseio.com/.json?orderBy="height"&startAt=3'
And this query finds all dinosaurs, starting with Stegosaurus.
curl 'https://dinosaur-facts.firebaseio.com/.json?orderBy="$key"&startAt="stegosaurus"'
This is not possible using the REST API.
However, you can run the Node.js client on your own server and request data this way: https://www.firebase.com/docs/nodejs-quickstart.html
