Optimize Firestore Import to Reduce Bundle Size

Low Risk

The large bundle size is due to importing the entire Firestore package, which includes many features that may not be needed for your application. By using modular imports, you can significantly reduce the bundle size by only including the necessary parts of the Firestore SDK.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Install Firebase Modular SDK

    Ensure you are using the Firebase modular SDK, which allows for tree-shaking and reduces the bundle size by only including the parts of the SDK that you actually use.

    bash
    npm install firebase
  2. 2

    Import Firestore Functions Individually

    Instead of importing the entire Firestore package, import only the functions you need from the Firebase modular SDK. This will help in reducing the bundle size significantly.

    typescript
    import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';
  3. 3

    Initialize Firestore

    After importing the necessary functions, initialize your Firestore instance using the modular approach. This ensures that only the required code is included in your bundle.

    typescript
    const app = initializeApp(firebaseConfig);
const db = getFirestore(app);
  4. 4

    Check Bundle Size

    After making the changes, build your application and check the bundle size to confirm that it has been reduced. Use tools like Webpack Bundle Analyzer to visualize the bundle.

    bash
    npm run build && npx webpack-bundle-analyzer dist/bundle.js

Validation

To confirm the fix worked, check the size of your final bundle using a tool like Webpack Bundle Analyzer. The size should be significantly smaller compared to the previous build with the full Firestore import.
