Setup Firebase

Since we are using Firebase & Cloud Firestore in GCP services, we need to configure The Firebase Admin SDK to interact with Firebase from our local environment. To set GOOGLE_APPLICATION_CREDENTIALS environment variable you can follow these steps at the following link: https://firebase.google.com/docs/admin/setup#initialize_the_sdk_in_non-google_environments

Installation

1. Clone repository

git clone https://github.com/GymLens/Cloud-Computing.git

2. Install dependencies

go mod tidy

3. Set up the environment variables by creating a .env file (refer to .env section below).

touch .env

4. Run the application

make run

5. Navigate to http://localhost:8080/api/ping

Environment Variables

The following environment variables are required to run the GymLens backend:

• PORT: The port on which the server will listen.
• GOOGLE_APPLICATION_CREDENTIALS: The credentials for the GCP.
• FIREBASE_API_KEY: The secret key for Firebase token generation and validation.

Make sure to set these variables in the .env file before running the application.
