Overview:

SvelteFire is a minimal yet powerful library that simplifies the way developers work with Firebase in Svelte. It allows users to access users, realtime Firestore, and Realtime Database data as Svelte stores. The library provides automatic subscription disposal to prevent memory and cost leaks, a better TypeScript experience for Firebase, and an easy way to handle complex relational data between Auth, Firestore, and Realtime Database. SvelteFire also allows for easy hydration of server data into a realtime Firebase stream.

Features:

• Access users, realtime Firestore, and Realtime Database data as Svelte stores
• Automatic subscription disposal to prevent memory and cost leaks
• Better TypeScript experience for Firebase
• Easy handling of complex relational data between Auth, Firestore, and Realtime Database
• Hydration of server data into a realtime Firebase stream
• Built-in components for Firestore and Realtime Database
• FirebaseApp component to put the Firebase SDK into Svelte context
• Components for handling current user, fetching documents, fetching collections, and fetching nodes from Realtime Database

Installation:

To install SvelteFire, follow these steps:

1. Install Firebase by running the following command:

npm i firebase v9+

2. Initialize Firebase in a file, such as lib/firebase.js, by importing the necessary Firebase modules and initializing the Firebase app. Here’s an example:

import { initializeApp } from 'firebase/app';
import { getFirestore, collection } from 'firebase/firestore';

const config = {
  // Your Firebase configuration object goes here
};

const firebaseApp = initializeApp(config);
const firestore = getFirestore(firebaseApp);

export { firestore };

3. Wrap your Svelte app with the FirebaseApp component in your root layout:

<script>
  import { FirebaseApp } from 'sveltefire';
  import { firestore } from './lib/firebase';

  const firebaseConfig = {};
</script>

<FirebaseApp {firebaseConfig}>
  <!-- Your Svelte app goes here -->
</FirebaseApp>

4. Use the various components and stores provided by SvelteFire to access Firebase data in your Svelte app.

Summary:

SvelteFire is a powerful library that simplifies working with Firebase in Svelte. It provides easy-to-use components and stores for accessing and managing Firebase data in realtime. With features like automatic subscription disposal, better TypeScript support, and support for complex relational data, SvelteFire streamlines Firebase development in Svelte projects. Plus, it allows for easy hydration of server data into a realtime Firebase stream. Overall, SvelteFire is a valuable tool for Svelte developers who want to integrate Firebase into their applications.
