    What is re-base?

    React.js makes managing state easy to reason about. Firebase makes persisting your data easy to implement. re-base, inspired by Relay, combines the benefits of React and Firebase by allowing each component to specify its own data dependency. Forget about your data persistence and focus on what really matters, your application's state.

    Why re-base?

    I spent a few weeks trying to figure out the cleanest way to implement Firebase into my React/Flux application. After struggling for a bit, I tweeted my frustrations. I was enlightened to the fact that Firebase and Flux really don't work well together. It makes sense why they don't work together, because they're both trying to accomplish roughly the same thing. So I did away with my reliance upon Flux and tried to think of a clean way to implement React with Firebase. I came across ReactFire built by Jacob Wenger at Firebase and loved his idea. Sync a Firebase endpoint with a property on your component's state. So whenever your data changes, your state will be updated. Simple as that. The problem with ReactFire is because it uses Mixins, it's not compatible with ES6 classes. After chatting with Jacob Turner, we wanted to create a way to allow the one way binding of ReactFire with ES6 classes along some more features like two way data binding and listening to Firebase endpoints without actually binding a state property to them. Thus, re-base was built.

    Installing

    $ npm install --save re-base

    API

    Firebase Real Time Database

    Overview

    • syncState: Two way data binding between any property on your component's state and any endpoint in Firebase. Use the same API you're used to to update your component's state (setState), and Firebase will also update.
    • bindToState: One way data binding. When your Firebase endpoint changes, the property on your state will update as well.
    • listenTo: When your Firebase endpoint changes, it will invoke a callback passing it the new data from Firebase.
    • fetch: Retrieve data from Firebase without setting up any binding or listeners.
    • post: Add new data to Firebase.
    • push: Push new child data to Firebase.
    • update: Update child data using only the referenced properties
    • remove: Remove data from Firebase
    • removeBinding: Remove a Firebase listener before the component unmounts if you need to. (Listeners are automatically cleaned up when component unmounts)
    • reset: Removes all of the Firebase listeners.

    Purpose

    Accepts an initialized firebase database object

    Arguments
    1. initialized firebase database (Object)
    Return Value

    An instance of re-base.

    Example using all of firebase
    var Rebase = require('re-base');
    var firebase = require('firebase');
    var app = firebase.initializeApp({
          apiKey: "apiKey",
          authDomain: "projectId.firebaseapp.com",
          databaseURL: "https://databaseName.firebaseio.com",
          storageBucket: "bucket.appspot.com",
          messagingSenderId: "xxxxxxxxxxxxxx"
    });
    var base = Rebase.createClass(app.database());
     
    Example using only the firebase database component
    var Rebase = require('re-base');
    var firebase = require('firebase/app');
    var database = require('firebase/database');
    var app = firebase.initializeApp({
          apiKey: "apiKey",
          authDomain: "projectId.firebaseapp.com",
          databaseURL: "https://databaseName.firebaseio.com",
          storageBucket: "bucket.appspot.com",

      • onFailure: (Function - optional) A callback function that will be invoked if the current user does not have read or write permissions at the location.
    Return Value

    An object which you can pass to removeBinding if you want to remove the listener while the component is still mounted.

      }).catch(error => {
        //handle error
      });
     

    removeBinding(ref)

    Purpose

    Clean up a listener. Listeners are automatically cleaned up when components unmount, however if you wish to remove a listener while the component is still mounted this will allow you to do that. An example would be if you want to start listening to a new endpoint in response to a prop change.

    Arguments
    1. ref (Object)
      • The return value of syncState, bindToState, or listenTo
    Return Value

    No return value

    Example

    componentWillUnmount(){
      base.removeBinding(this.ref);
    }

    reset()

    Purpose

    Removes every Firebase listener and resets all private variables.

    Arguments

    No Arguments

    Return Value

    No return value


    Using Firebase Queries

    Use the query option to utilize the Firebase Query API. For a list of available queries and how they work, see the Firebase docs.

    Queries are accepted in the options object of each read method (syncState, bindToState, listenTo, and fetch). The object should have one or more keys of the type of query you wish to run, with the value being the value for the query. For example:

    base.syncState('users', {
      context: this,
      state: 'users',
      asArray: true,
      queries: {
        orderByChild: 'iq',
        limitToLast: 3
      }
    })

    The binding above will sort the users endpoint by iq, retrieve the last three (or, three with highest iq), and bind it to the component's users state. NOTE: This query is happening within Firebase. The only data that will be retrieved are the three users with the highest iq.

    }
    componentWillUnmount(){
      base.removeBinding(this.ref);
    }

    reset()

    Purpose

    Removes every Firestore listener.

    Arguments

    No Arguments

    Return Value

    No return value


    Using Firestore Queries

    Use the query option to utilize the Firestore Query API. For a list of available queries and how they work, see the Firestore docs.

    Queries are accepted in the options object of each collection read method (listenToCollection, bindCollection, get(Collection)). You can also use them with removeFromCollection to remove documents that match the query

    The query options takes a function that will receive the collection reference as its only argument. You can then apply any of the available methods you with to run and must return the reference.

    base.bindCollection('users', {
      state: 'users',
      context: this,
      query: (ref) => {
        return ref.where('type', '==', 'subscriber')
                  .where('joined', '>', yesterday)
                  .orderBy('joined');
      }
    })

    Upgrading to re-base 3.x from 2.x

    Major Changes:

    3.x no longer requires you to include the full Firebase SDK in your app. This means that you need to include the parts of Firebase SDK you wish to use and handle initialization of the firebase services in your app instead of re-base doing this for you. re-base only requires you pass it the initialized database service. This also means that the authentication helpers are deprecated and re-base no longer exposes the firebase services.

    3.x also removes listeners automatically for you on componentWillUnmount so you don't have to explicitly call removeBinding. removeBinding is still available if you need to remove a listener while the component is still mounted. For instance, if you are adding and removing listeners in response to a prop change.

    To help with migrating to 3.x please see the Migration Guide for the equivalent Firebase SDK methods to use for the deprecated auth helpers.

    Changes your re-base initialization:

    Change this....

     
    var Rebase = require('re-base');
    var base = Rebase.createClass({
          apiKey: "apiKey",
          authDomain: "projectId.firebaseapp.com",
          databaseURL: "https://databaseName.firebaseio.com",
          storageBucket: "bucket.appspot.com",
    });
     

    To this...

     
    var Rebase = require('re-base');
    var firebase = require('firebase');
    var app = firebase.initializeApp({
          apiKey: "apiKey",
          authDomain: "projectId.firebaseapp.com",
          databaseURL: "https://databaseName.firebaseio.com",
          storageBucket: "bucket.appspot.com",
    });
    var base = Rebase.createClass(app.database());
     

    Changes to Database methods


    No changes. Your existing code should work.
