4) Setting Up the Database

This project utilizes MongoDB as its database. Follow these steps to set up the database:

1. MongoDB Installation:

   • Install MongoDB on your system. You can download it from the official MongoDB website.
   • Follow the installation instructions for your operating system.

2. Start MongoDB Server:

   • Once installed, start the MongoDB server. You can do this by running the mongod command in your terminal.

3. Create a Database:

   • Open a new terminal and run the mongo command to open the MongoDB shell.
   • Create a new database for the project. For example:

     use GoGrabDB

4. Configure .env File:

   • Open the .env file in the project's root directory.
   • Set the MAIN_DB_URI variable to the connection string for your MongoDB database. Example:

     MAIN_DB_URI=mongodb://localhost:27017/GoGrabDB

5. Verify Connection:

   • Ensure that the project's backend server connects successfully to the MongoDB database. Check the terminal/console for any connection errors.

By following these steps, you'll have the MongoDB database set up and configured for the GoGrab E-Commerce project. Adjust connection details and configurations according to your specific needs.

5) Setting Up the Project

To set up and run the project locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/mobin4321/GoGrab.git
   cd GoGrab

2. Navigate to the backend directory and install dependencies:

    cd backend
    npm install

3. Start both data and auth servers:

    npm run start
    npm run authStart

4. Once both servers are running correctly, navigate to the frontend directory and install dependencies:

    cd ../frontend
    npm install

5. Start the frontend server:

   npm start

   Now, you have a perfectly working project.

Environment Variables

This project relies on an .env file to securely store sensitive configuration details which is not included in the current repository. To set up the environment variables, follow these steps:

1. Create a file named .env in the project's root directory.

2. Populate the file with the following variables:

AUTH_SERVER_PORT=
MAIN_SERVER_PORT=
MAIN_DB_URI=
SALT_ROUNDS=
CRYPTO_SECRET_KEY=
CRYPTO_ALGORITHM=
CRYPTO_IV_LENGTH=
SMTP_SERVICE=
SMTP_HOST=
SMTP_PORT=
SMTP_USER=
SMTP_PASSWORD=
