# Firebase + Vue Integration Setup Guide This guide provides instructions for setting up and integrating Firebase with a Vue 3 application. ## Prerequisites - Node.js and npm installed - Vue 3 project initialized - Firebase project created ## Installation 1. Install required dependencies: ```bash npm install firebase vuefire ``` ## Configuration 2. Create a new file `src/firebase.ts` for Firebase configuration: ```typescript import { initializeApp } from 'firebase/app'; import { getFirestore } from 'firebase/firestore'; import { getAuth } from 'firebase/auth'; import { getStorage } from 'firebase/storage'; const firebaseConfig = { apiKey: import.meta.env.VITE_FIREBASE_API_KEY, authDomain: import.meta.env.VITE_FIREBASE_AUTH_DOMAIN, projectId: import.meta.env.VITE_FIREBASE_PROJECT_ID, storageBucket: import.meta.env.VITE_FIREBASE_STORAGE_BUCKET, messagingSenderId: import.meta.env.VITE_FIREBASE_MESSAGING_SENDER_ID, appId: import.meta.env.VITE_FIREBASE_APP_ID }; // Initialize Firebase export const app = initializeApp(firebaseConfig); export const db = getFirestore(app); export const auth = getAuth(app); export const storage = getStorage(app); ``` 3. Set up VueFire plugin in `src/main.ts`: ```typescript import { createApp } from 'vue'; import { VueFire, VueFireAuth } from 'vuefire'; import App from './App.vue'; import { app as firebaseApp } from './firebase'; const app = createApp(App); app.use(VueFire, { firebaseApp, modules: [VueFireAuth()] }); app.mount('#app'); ``` ## Usage Examples ### Authentication Component ```vue ``` ### Firestore Data Management Component ```vue ``` ### File Storage Component ```vue ``` ## Security Considerations 1. Never expose Firebase configuration in client-side code without proper security measures 2. Implement proper authentication state management 3. Use environment variables for sensitive configuration 4. Set up appropriate Firestore security rules 5. Implement proper file upload restrictions 6. Use Firebase App Check for additional security 7. Implement proper error handling for all operations ## Best Practices 1. Use TypeScript for better type safety 2. Structure your Firebase services in modules 3. Implement proper error handling 4. Use VueFire's composables for reactive data 5. Implement proper loading states 6. Use Firebase emulators for local development 7. Follow Vue's composition API best practices 8. Implement proper data validation 9. Use Firebase indexes for complex queries ## Troubleshooting 1. Check Firebase console for errors 2. Verify security rules configuration 3. Check network requests in browser developer tools 4. Use Firebase debugging tools 5. Monitor Firebase usage and quotas 6. Check Vue DevTools for component state 7. Verify environment variables ## Additional Resources - [Firebase Documentation](https://firebase.google.com/docs) - [VueFire Documentation](https://vuefire.vuejs.org/) - [Vue 3 Documentation](https://vuejs.org/) - [Firebase Console](https://console.firebase.google.com/)
