Firebase-to-MinIO Migration Tool

This project provides a script for migrating images from Firebase Storage to a MinIO storage instance. It's built with Node.js and TypeScript, offering a straightforward way to transfer files without modifying them.

Features

• Direct transfer of images from Firebase Storage to MinIO.
• Utilizes environment variables for secure configuration.
• Easy to set up and run with minimal dependencies.

Prerequisites

Before you start, ensure you have the following installed:

• Node.js (v12.x or later)
• npm (comes with Node.js)

Setup Instructions

1. Clone the repository:

   If you have a Git repository for this project, clone it. Otherwise, ensure you have the project files in your working directory.

2. Install dependencies:

   Navigate to your project directory and run:

   npm install

3. Configure environment variables:

   Create a .env file in the root of your project directory. Add the following environment variables with your specific values:

   FIREBASE_PROJECT_ID=your_firebase_project_id
   FIREBASE_SERVICE_ACCOUNT_BASE64=your_base64_encoded_service_account
   FIREBASE_STORAGE_BUCKET=your_firebase_storage_bucket_url
   
   MINIO_ENDPOINT=your_minio_endpoint
   MINIO_PORT=your_minio_port
   MINIO_ACCESS_KEY=your_minio_access_key
   MINIO_SECRET_KEY=your_minio_secret_key
   MINIO_BUCKET_NAME=your_minio_bucket_name
   MINIO_USE_SSL=true_or_false
   

   For FIREBASE_SERVICE_ACCOUNT_BASE64, encode your Firebase service account JSON file to a Base64 string and paste it here.

4. Transpile TypeScript to JavaScript:

   Run the TypeScript compiler to transpile the .ts files into .js files in the dist directory:

   npx tsc

5. Run the migration script:

   With the setup complete, start the migration process by running:

   npx ts-node --transpile-only src/migrate.ts

How It Works

The script authenticates with Firebase using the provided service account details, lists all files in the specified Firebase Storage bucket, and transfers them to the configured MinIO bucket. It does not modify the files in any way.

Security Considerations

Ensure that your .env file is never committed to your version control system. This file contains sensitive credentials that should not be made public.

Troubleshooting

• Authentication Errors: Double-check your Firebase and MinIO credentials in the .env file.
• Network Issues: Ensure there are no network connectivity issues between your machine and both Firebase and MinIO services.
• SSL/TLS Errors: If you encounter SSL/TLS-related errors, verify the MINIO_USE_SSL configuration and ensure your MinIO instance's SSL setup is correct.

For more help, refer to the error logs generated by the script, which can provide insights into what went wrong.
