React Application Expo Framework with user validation Firebase Integration -- 2

Job ID: 38401537

Budget: $15 – $25 USD

I have an old versioned React application, built using React 15 with Expo framework and Firebase for memory storage. The application features user authentication and real-time updates.

I'm looking to update this application to the latest version of React with minimal code changes. The ideal freelancer will be well-versed in React, Expo framework, and Firebase. The project will involve the solving the initial issues:

ERROR FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created - call initializeApp() first (app/no-app)., js engine: hermes
ERROR Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called., js engine: hermes

It is not possible to share the complete appl code via Github. But the app.js and the FirefoxConfig.js and other environmental files.

Ideal skills for this project include:
- Expertise in React and React Native
- Experience with Expo framework
- Proficiency in Firebase integration
- Ability to update an existing application while maintaining core features
