The Pro MERN Stack GitHub repository, previously accompanying the book by Vasan Subramanian, has now been officially deprecated in favor of the second edition. While this repository may no longer receive updates, it serves as a valuable archive of knowledge for developers. In this article, we will walk you through how to effectively utilize the existing resources in this repository and troubleshoot common issues you may encounter.

Getting Started with the Repository

This repository contains a compilation of source codes that correspond to each chapter’s application in the book. To explore the complete source code and the differences from previous segments, you can navigate through the respective sections in the repository. Here’s how you can get started:

Installation Steps

• Step 1: Install Node.js (with npm) and MongoDB on your local machine.
• Step 2: Clone the repository using the command: git clone https://github.com/vasansr/pro-mern-stack
• Step 3: Navigate to the project directory.
• Step 4: Run npm install to install the required packages.
• Step 5: Compile the project by running npm run compile followed by npm run compile-server.
• Step 6: Start the server with npm start. The server will run on port 3000.
• Step 7: (Optional) Seed the database by executing mongo scripts/init.mongo.js for initial data.

Understanding the Repository Structure Through an Analogy

Think of the Pro MERN Stack repository as a large library containing books on various topics of web development using the MERN stack (MongoDB, Express.js, React.js, Node.js). Each chapter of the book represents a different section of the library, and the source codes are like the items on the shelves of those sections.

When you want to learn about creating a REST API, you simply pick the “Express REST APIs” section, where you’ll find multiple code listings and the variations from previous chapters. Just as a library can lend out books but may not always have the latest edition, this repository preserves past knowledge, giving developers a chance to explore and experiment with available resources even though it is now outdated.

Troubleshooting: Common Issues and Solutions

• Issue: Error messages when starting the server.
  • Solution: Ensure you have all dependencies installed correctly and that the package versions are compatible. Check your package.json for version mismatches.
• Issue: MongoDB not connecting.
  • Solution: Confirm that MongoDB is running on your machine and can accept connections. Also, verify your connection string in the code.
• Issue: Missing scripts.
  • Solution: Make sure that you are in the right directory where the scripts are located and that they are correctly named.
