Product Manager Express API

ScreenShoot PostMan



This is an Express API for managing users, roles, products, and orders. It provides various endpoints for authentication, user management, role management, product management, and order handling.

Installation

To run this API, you need to have Node.js and npm (Node Package Manager) installed on your system. Follow these steps to get started:

  1. Clone the project repository or download the source code.

  2. Open a terminal and navigate to the project directory.

  3. Install the required dependencies by running the following command:

    npm install

    Script Execution

This project provides several scripts that can be executed using the npm (Node Package Manager) command-line tool. The scripts are defined in the package.json file. Below are the available scripts:

  • start: Starts the server by running the index.ts file using the ts-node TypeScript execution engine. This script is typically used in production environments.
  • seed:role: Executes the role.seeder.ts file to seed the database with role data. This script can be used to initialize the roles in the system.
  • seed:product: Executes the product.seeder.ts file to seed the database with product data. This script can be used to populate the product catalog.
  • seed:order: Executes the order.seeder.ts file to seed the database with order data. This script can be used for testing or to create sample orders.

To execute a script, open a terminal or command prompt in the project's root directory and run the following command:

npm run <script-name>

Replace <script-name> with the name of the script you want to execute. For example, to start the server, run:

npm run start

Note: Some endpoints require specific permissions. Make sure to include the necessary permission when making requests.

Middleware

This API uses middleware functions to handle authentication and permission checks for certain routes.

Authentication Middleware

  • authMiddleware: Middleware function that ensures the user is authenticated before accessing protected routes. Applied to routes that require authentication.

Permission Middleware

  • permissionMiddleware(permission): Middleware function that checks if the authenticated user has the specified permission before accessing protected routes. Applied to routes that require specific permissions.

To use the middleware, simply import them from the respective files and apply them to the desired routes in your Express application.

Example usage:

const express = require('express');
const app = express();
const { authMiddleware, permissionMiddleware } = require('./middleware/auth.middleware');

// Apply authentication middleware to all routes that require authentication
app.use(authMiddleware);

// Apply permission middleware to specific routes that require certain permissions
app.get('/api/users', permissionMiddleware('User'), (req, res) => {
  // Handle request
});

app.put('/api/users/:id', permissionMiddleware('User'), (req, res) => {
  // Handle request
});

// Other routes...

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
