Welcome to your guide on building a robust Node.js back end web application using TypeScript. This project utilizes a REST API interface through Express.js, user JWT authentication with Passport.js, and MongoDB for data storage via Mongoose.js. Let’s dive into the process step by step!

Getting Started

This application is crafted to run smoothly on your local machine. Here are the primary technologies that make it happen:

• Docker: Containerization platform to simplify the deployment process.
• Docker Compose: Tool for defining and running multi-container Docker applications.
• Visual Studio Code: A highly popular code editor for development tasks.

Key Features

The application is built with the following significant features:

• REST API for seamless communication between client and server.
• User authentication using JSON Web Tokens (JWT) for security.
• MongoDB as a reliable data storage solution.

Building the Application

Before diving into the code, let’s describe it using an analogy. Imagine your application is like a restaurant.

• Frontend: The menu that customers see and order from.
• Backend (Node.js + Express): The kitchen where the chefs (server) prepare food (data). It takes orders (API requests) and returns the meals (API responses).
• JWT Authentication: The bouncer checking if customers have a valid reservation (token) to enter the restaurant.
• MongoDB: The pantry storing all ingredients (data) needed to make the dishes (responses).

Just as a well-run restaurant ensures that every order is properly managed, your application organizes data requests and responses using the frameworks and libraries mentioned.

Troubleshooting

If you encounter any issues while setting up your Node.js back end application, consider the following troubleshooting ideas:

• Ensure that all dependencies are correctly installed using npm.
• Check that Docker is running properly if you’re using it for your setup.
• Verify your MongoDB connection string in the configuration files.
• If you run into issues with JWT, confirm your user authentication setup.
