Operating System

mac OS Ventura 13.6.4

Browser Version

Chrome/124.0.6367.119

Firebase SDK Version

10.11.1

Firebase SDK Product:

Auth, Database

Describe your project's tooling

• *IDE: Replit IDE
• Framework: React
• Bundler: Vite
• Database: Firebase Realtime Database
• Language: JavaScript (ES6)

Describe the problem

Error: "SyntaxError: The requested module '/node_modules/.vite/deps/firebase_app.js?v=40e893b6' does not provide an export named 'default' (at firebase.js:2:8)"

Context: This error occurs when attempting to import Firebase into a React component, specifically in a file named firebase.js. The error indicates that the module path /node_modules/.vite/deps/firebase_app.js does not provide a default export as expected.

Steps and code to reproduce issue

1. Initialize Project: Create a new React project using Vite as the bundler.

2. Install Firebase: Install Firebase SDK for JavaScript using npm or yarn:

   npm install firebase

3. Configure Firebase: Create a firebase.js file to configure Firebase in the project. Example:

   // firebase.js
   import firebase from "firebase/app";
   import "firebase/auth";
   import "firebase/database";
   
   const firebaseConfig = {
    // Your Firebase config here
   };
   
   firebase.initializeApp(firebaseConfig);
   
   export const auth = firebase.auth();
   export const database = firebase.database();

4. Create Component Using Firebase: Create a component that uses Firebase, such as a signup form. Example:

   // Signup.js
   import React, { useState } from 'react';
   import { auth } from './firebase';
   
   const Signup = () => {
    const [email, setEmail] = useState('');
    const [password, setPassword] = useState('');
   
    const handleSignup = async (e) => {
      e.preventDefault();
      try {
        await auth.createUserWithEmailAndPassword(email, password);
        console.log('User signed up successfully');
      } catch (error) {
        console.error('Error signing up:', error.message);
      }
    };
   
    return (
      <div>
        <h2>Signup</h2>
        <form onSubmit={handleSignup}>
          <input
            type="email"
            placeholder="Email"
            value={email}
            onChange={(e) => setEmail(e.target.value)}
          />
          <input
            type="password"
            placeholder="Password"
            value={password}
            onChange={(e) => setPassword(e.target.value)}
          />
          <button type="submit">Sign up</button>
        </form>
      </div>
    );
   };
   
   export default Signup;

5. Import Component: Import the Signup component into your main application file (App.js or similar) and use it.

6. Run Project: Start the development server using Vite and navigate to the signup page.

Expected Result

The signup form should render without any errors and should work correctly.

Actual Result

The following error is encountered:

SyntaxError: The requested module '/node_modules/.vite/deps/firebase_app.js?v=40e893b6' does not provide an export named 'default' (at firebase.js:2:8)

Hi @aravinthkumarpk, thanks for reaching out to us. I was able to replicate the behavior that you've mentioned. I noticed that you're using the namedspace coding structure but importing the modular API. Here is a code snippet for importing the namespace API:

// compat packages are API compatible with namespaced code
import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';

You can also checkout this documentation about migrating to modular version of the SDK. I'll be closing this issue now. If you encounter another issue, feel free to create a new one.

Thanks for the super quick response. Appreciate it @jbalidiong. Put out a public appreciation post as well https://twitter.com/aravinthkumarpk/status/1788659691561603341 🙌

Also, there was a minor niggle in the suggestion. I am using real time database and hence had to use "import 'firebase/compat/database' instead of import 'firebase/compat/firestore'.
