Advanced_api

Advanced_api is a feature-rich, scalable, and secure RESTful API built with Node.js and Express. It is designed for production-level web applications, providing comprehensive features like authentication, authorization, caching, real-time communication, and more. This project serves as an ideal foundation for building complex backend services.

Table of Contents

Features

  • CRUD Operations: Easily manage resources via RESTful APIs.
  • JWT-based Authentication: Secure your API with JSON Web Tokens.
  • Role-based Access Control (RBAC): Provide access based on user roles.
  • Data Validation & Sanitization: Protect your API from invalid or malicious input.
  • Rate Limiting: Mitigate abuse by limiting the number of requests.
  • Caching with Redis: Improve performance with efficient caching.
  • Pagination & Filtering: Handle large datasets smoothly.
  • Error Handling & Logging: Centralized error management and logging using Winston.
  • API Versioning: Backward compatibility for smooth API evolution.
  • Automated Testing: Unit, integration, and end-to-end tests ensure robustness.
  • Internationalization (i18n): Multilingual support for broader reach.
  • GraphQL Integration: Flexible data querying with GraphQL endpoints.
  • Real-time Communication: WebSocket support for real-time updates.

Technologies Used

  • Node.js: JavaScript runtime for fast and scalable server-side applications.
  • Express.js: Minimalist web framework for Node.js.
  • MongoDB: NoSQL database for storing and managing data.
  • Mongoose: MongoDB object modeling for robust data handling.
  • Redis: Caching layer to optimize performance.
  • JWT: Token-based authentication for secure user sessions.
  • Socket.IO: Real-time communication using WebSockets.
  • Apollo Server: GraphQL support for flexible API queries.
  • Swagger: Automatic generation of interactive API documentation.
  • Jest & Supertest: Comprehensive testing tools for unit, integration, and e2e tests.

Installation

Prerequisites

Before installing and running the project, make sure you have the following installed:

  • Node.js (v14 or higher)
  • MongoDB (v4 or higher)
  • Redis (for optional caching)

Setup

Clone the repository:

git clone https://github.com/your-username/advanced_api.git
cd advanced_api

Installation Steps

Install dependencies:

npm install

Set Up Environment Variables

Create a .env file in the root directory and add the required variables (refer to the Environment Variables section).

Run the Development Server

npm run dev

Environment Variables

In the .env file, configure the following:

# Server Configuration
PORT=5000

# MongoDB Configuration
MONGO_URI=mongodb://localhost:27017/your_database_name

# Redis Configuration
REDIS_HOST=localhost
REDIS_PORT=6379

# JWT Configuration
JWT_SECRET=your_jwt_secret
JWT_EXPIRATION=1h

# Other configurations
NODE_ENV=development

Usage

Once the server is running, the API will be accessible at http://localhost:5000. You can interact with the API using Postman or any other API testing tool.

Available Routes

Method Endpoint Description
GET /api/v1/products Fetch all products
POST /api/v1/products Create a new product
GET /api/v1/products/:id Fetch a product by ID
PUT /api/v1/products/:id Update a product by ID
DELETE /api/v1/products/:id Delete a product by ID

For authentication routes and other features, please check the API documentation below.

API Documentation

Advanced_api uses Swagger for API documentation. After starting the server, you can view the interactive API docs at:

http://localhost:5000/api-docs

Testing

The project includes a comprehensive suite of unit, integration, and end-to-end tests written using Jest and Supertest.

To run tests:

npm run test

Test Structure

  • Unit Tests: Test individual components such as controllers or services.
  • Integration Tests: Test interactions between different components like routes and controllers.
  • End-to-End Tests: Simulate real-world scenarios and test the entire API flow.

Real-time Features

Advanced_api supports real-time communication through Socket.IO. This allows for features like live updates, notifications, and real-time data streaming.

To connect to the WebSocket server:

const socket = io('http://localhost:5000');
