These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Before you begin, ensure you have the following installed:

Node.js
npm (Node Package Manager)
PostgreSQL

Installing

A step-by-step series of examples that tell you how to get a development environment running:

Clone the repository:

git clone https://github.com/Collins87mbathi/auth-system.git

Navigate to the project directory: Once you have cloned the repository, navigate to the project directory.
```
cd auth-system
```
Install the required npm packages: Install all dependencies listed in package.json by running the following command:
```
npm install
```
Set up the environment variables: Create a .env file in the root directory of the project. Include the following environment variables adjusted to your specific configuration:
```
PORT = 8000
DATABASE = 
DATABASE_USER = 
DATABASE_PASSWORD =
```
Set up the environment variables: Initialize the database (Make sure PostgreSQL is running): Run the database migrations with the Sequelize CLI to set up your schema in PostgreSQL.
```
npx sequelize-cli db:migrate
```
Start the development server: Kick off the Express server with the start script defined in your package.json.
```
npm start
```

This command will start the server on http://localhost:8000 or the port you have specified in your environment variables.

Usage

After starting the server, you can make API requests to endpoints defined under /api/auth for authentication and /api/users for user management.
