Integrating Firebase with your Vue applications doesn’t have to be complicated. With VuexFire, you can easily manage your state while staying in sync with your Firebase database. This guide will walk you through everything you need to know to set it up effectively.

1. Getting Started with VuexFire

VuexFire has transitioned to a new home at vuejs/vuefire. Make sure you’re aware of the versions it supports: only Vue 2, Vuex 2, and Firebase JavaScript SDK versions 2.3-4.5. If you need to use an earlier version, be sure to check out the v1 branch.

2. Installation

Follow these simple steps to install VuexFire:

• Using a CDN:

<script src="https://unpkg.com/vuexfire@next"></script>

• In module environments (CommonJS):

npm install vue firebase vuexfire@next --save

3. Setting Up Your Store

To utilize VuexFire, start by enhancing your Vuex store. Consider your store as a library where Firebase data will be stored as books (or arrays/objects).

Here’s how to set it up:

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
})

4. Enhancing Actions

Your actions are like librarians that help manage your books. To enhance the actions for VuexFire, use an action enhancer.

import { firebaseAction } from 'vuexfire';

const setTodosRef = firebaseAction(({ bindFirebaseRef, unbindFirebaseRef }, ref) => {
  bindFirebaseRef('todos', ref); // This binds the reference
  // To unbind a reference
  unbindFirebaseRef('user');
});

5. Component Access

Accessing the data in your components is quite straightforward, just like checking out a book. For instance:

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

6. Browser Support and Polyfills

VuexFire requires basic WeakMap support, which may not be present in older browsers like Internet Explorer 11. If you are supporting these browsers, you will need to include a polyfill, such as the one found at Benvie/WeakMap.

7. Troubleshooting Tips

If you run into issues using VuexFire, try these troubleshooting tips:

• Ensure you are using the correct versions of Vue, Vuex, and Firebase SDK.
• Double-check your mutations and state definitions for typos.
• If something isn’t binding correctly, look at your action enhancer and ensure it is set up correctly.

8. Understanding VuexFire’s Mechanism

Think of VuexFire as a news ticker that constantly broadcasts updates from your Firebase database. It listens for changes and makes the required mutations in your Vuex store automatically, keeping your app’s state synchronized without needing to manually fetch or update data.

9. Conclusion

VuexFire simplifies the process of building real-time applications with Firebase and Vue. By following the steps listed above, you lay a solid foundation for your app to thrive.
