VuexFire

SSR ready Firebase binding for Vuex

Supports only Vue 2, Vuex 2 and Firebase JavaScript SDK 2/3/4/5. If you need an older version check the v1 branch: npm i -D [email protected]

Installation

1. Using a CDN:

<script src="https://unpkg.com/[email protected]"></script>

2. In module environments, e.g CommonJS:

npm install vue firebase [email protected] --save

Usage

Add the mutations to your root Store and make sure to define the property you want to bind in the state first:

import { firebaseMutations } from 'vuexfire'
const store = new Vuex.Store({
  state: {
    todos: [], // Will be bound as an array
    user: null // Will be bound as an object
  },
  mutations: {
    // your mutations
    ...firebaseMutations
  }
})

It works with modules as well, but you don't need to add the mutations there:

const store = new Vuex.Store({
  modules: {
    todos: {
      state: {
        todos: [], // Will be bound as an array
        user: null // Will be bound as an object
      },
    }
  }
})

In order to use VuexFire, you have to enhance actions. This action enhancer takes the actual action and enhances it with two additional parameters in the context, bindFirebaseRef and unbindFirebaseRef:

import { firebaseAction } from 'vuexfire'

const setTodosRef = firebaseAction(({ bindFirebaseRef, unbindFirebaseRef }, { ref }) => {
  // this will unbind any previously bound ref to 'todos'
  bindFirebaseRef('todos', ref)
  // you can unbind any ref easily
  unbindFirebaseRef('user')
})

Access it as a usual piece of the state:

const Component = {
  template: '<div>{{ todos }}</div>',
  computed: Vuex.mapState(['todos']),
  created () {
    this.$store.dispatch('setTodosRef', db.collection('todos'))
  }
}

Browser support

VuexFire requires basic WeakMap support, which means that if you need to support any of these browsers:

• IE < 11
• Safari < 7.1
• Android < 5.0

You'll have to include a polyfill. You can use Benvie/WeakMap.

You can find more information about WeakMap support here.

How does it work?

VuexFire uses multiple global mutations prefixed by vuexfire/ to call the actual mutations to modify objects and arrays. It listens for updates to your firebase database and commits mutations to sync your state. Thanks to the action enhancer firebaseAction, it gets access to the local state and commit so it works with modules too 👍

Examples

API

firebaseMutations

This object contains VuexFire internal mutations. They are all prefixed by vuexfire/. This object must be added in the root Store mutations object.

bindFirebaseRef(key, ref)

Only available inside of an enhanced action

Binds a firebase reference to a property in the state. If there was already another reference bound to the same property, it unbinds it first.

bindFirebaseRef('todos', ref)

Returns a promise which will resolve when the data is ready, or throw an error if something goes wrong:

bindFirebaseRef('todos', ref).then(() => {
  commit('setTodosLoaded', true)
}).catch((err) => {
  console.log(err)
})

unbindFirebaseRef(key)

Only available inside of an enhanced action

Unbinds a bound firebase reference to a given property in the state.

unbindFirebaseRef('todos')
