Space_Launch - Node.js Backend & React.js Frontend

This project implements a Node.js backend API using Express for routing and Mongoose for interacting with a MongoDB database. It demonstrates best practices for modularity, data handling, and error management. React.js for frontend.

Key Technologies

• Node.js: JavaScript runtime environment for server-side development.
• Express.js: Nodejs Web framework for building web applications and APIs.
• Mongoose: ODM (Object Data Modeling) library for interacting with MongoDB databases.
• dotenv: Library for loading environment variables from a .env file (for security).
• Other Technologies I Used: Helmet for security, Morgan for logging

Project Structure

• app.js: Main application entry point, configures Express app and middleware.
• routes: Directory containing route handlers for specific API endpoints (e.g., /upcoming, /launches, etc.).
• models: Directory containing Mongoose models for data representation (e.g., Planet.js, Launch.js).
• services: Directory for utility functions or services used throughout the project (e.g., database connection logic).
• public: Directory for serving static files (e.g., HTML, CSS, JavaScript) if applicable.
• package.json: File containing project dependencies and scripts.

Getting Started

• Clone this repository
• Install dependencies: Check package.json for installation
• Create a .env file in the project root directory and set any necessary environment variables (e.g., port, database connection string).
• Start the server: npm start (or a custom script defined in package.json)

Testing

This project utilizes Jest, a popular testing framework for JavaScript, to ensure code quality and functionality. Unit tests cover various aspects of the API, including:

• Launches API
  • Successful retrieval of launches through GET requests to /v1/launches.
  • Successful creation of new launches through POST requests to /v1/launches with complete data validation.
  • Error handling for missing required launch properties and invalid launch dates in POST requests.

Testing Setup

• Before all tests, the code connects to the MongoDB database using mongoConnect with a timeout of 10 seconds.
• After each test, the code disconnects from the database using mongoDisconnect to avoid resource leaks.

Running Tests

• Install Jest: npm install jest --save-dev (if not already installed).
• Run tests: npm test (or a custom script defined in package.json).
