API Reference

FireChild

A FireChild instance is used to add listeners to grandchild locations.

var FireChild = require('fire-child');

new FireChild(ref)

Creates and returns a new FireChild instance to add listeners. Note that this ref can point to anywhere in your Firebase and can either be a string or an instance of the Firebase object.

// Create a FireChild object
var fireChild = new FireChild('https://<your-firebase>.firebaseio.com/');

FireChild.on(depth, eventType, callback, [cancelCallback], [context])

Adds a Firebase listener at the specified depth from the reference which created the FireChild.

// Add child_added eventType to grandchildren of Firebase reference
fireChild.on(1, 'child_added', function (childSnapshot, prevChildName) {});
