Project Setup and Database Configuration

This guide provides step-by-step instructions for setting up the project and configuring the database locally.

Before you begin, ensure you have the following installed on your machine:

Clone the Repository
```
git clone https://github.com/your-username/your-project.git
```
Replace https://github.com/your-username/your-project.git with the URL of your project repository.
Navigate to the Project Directory
```
cd your-project
```
Replace your-project with the name of your project directory.
Install Dependencies
```
npm install
```

Start PostgreSQL Service
```
sudo service postgresql start
```
Access PostgreSQL Shell
```
psql -U postgres
```
Create Database
```
CREATE DATABASE your_db_name;
```
Replace your_db_name with the desired name for your database.

Create User and Grant Privileges

CREATE USER your_db_user WITH ENCRYPTED PASSWORD 'your_db_password';

Replace your_db_user and your_db_password with your desired database username and password.

GRANT ALL PRIVILEGES ON DATABASE your_db_name TO your_db_user;

Create .env File
```
touch .env
```
Add Database and Application Configuration

Open the .env file and add the following configuration:
```
# PostgreSQL Database Configuration
DB_HOST=localhost
DB_PORT=5432
DB_USER=your_db_user
DB_PASSWORD=your_db_password
DB_NAME=your_db_name

# Express Application Configuration
PORT=3000
```
Replace your_db_user, your_db_password, and your_db_name with the database username, password, and name you configured earlier.

Start the Application
```
npm start
```
The application should now be running on http://localhost:3000.
