Firebase (2016) Shallow Query

Question

I\'m trying out Firebase (since Google\'s new release).

In the original version of Firebase the parameter shallow=true would return an object with { key: true

Answer 1

The ?shallow=true parameter in Firebase Database 2.x was only available in the REST API. See https://www.firebase.com/docs/rest/guide/retrieving-data.html#section-rest-uri-params.

In the new Firebase Database 3.x, the same parameter is still only available in the REST API. See https://firebase.google.com/docs/database/rest/retrieve-data#shallow

You're using a Firebase SDK (JavaScript from the looks of it), which never supported this parameter.

For more questions that have discussed this in the past, see:

• Firebase retrieve child keys but not values
• Firebase REST API working with shallow data
• How do I do a shallow query on Firebase iOS?
• Get Firebase child nodes' names without getting their children too in Firebase response?

Answer 2

This worked for me based on Frank's answer:

import request from 'request';

request({ url: "https://[YOUR-APP-ID].firebaseio.com/path/to/data/.json?shallow=true" }, (error, response, body) => {
    const shallowData = JSON.parse(body);
    console.log(shallowData);
});
