Welcome to this comprehensive guide on how to set up your very own Stack Overflow clone using the MERN stack. This project is designed to be a QA platform for both professional and novice programmers. In this post, we’ll walk you through the entire setup process, providing troubleshooting tips along the way.

Understanding the Tech Stack

Before we dive into the setup, let’s take a quick look at the technology stack that powers this project:

• Front-end:
  • Framework: React.js (with Redux)
  • Styling: SASS and Bootstrap
• Back-end:
  • Server: Node.js with Express.js
  • Database: MySQL with Sequelize
  • API Testing: POSTMAN

Setting Up the Project

There are two ways to set up the project: manually or using Docker. Let’s explore both methods step by step.

1. Manual Setup

Follow these steps for a manual installation:

1. Open your local CLI and create a new directory:

   mkdir Stackoverflow-Clone
   cd Stackoverflow-Clone

2. Set up the backend code:
   • Create a .env file based on the format in .env.example.
   • Clone the backend repository and install the necessary modules:

     git clone https://github.com/Mayank0255/Stackoverflow-Clone-Backend.git
     cd Stackoverflow-Clone-Backend
     npm install

   • Open your MySQL Client and create a new database:

     CREATE DATABASE stack_overflow;

     Note: Ensure the database name matches in the .env file.

   • Run the backend:

     npm start

3. Open another terminal and navigate back to the root folder:

   cd Stackoverflow-Clone

4. Set up the frontend code:
   • Clone the frontend repository and install the required modules:

     git clone https://github.com/Mayank0255/Stackoverflow-Clone-Frontend.git
     cd Stackoverflow-Clone-Frontend
     npm install

   • Run the frontend:

     npm start

2. Docker Setup

If you prefer to use Docker for containerization, here’s how you can do it:

• First, make sure to set up the environment variables in the .env file, especially if running the database on localhost.
• Next, build the Docker image:

  docker build -t stackoverflowclone .

• Run the container:

  docker run -d -p 5000:5000 stackoverflowclone

  The API will now be accessible via http://localhost:5000/api.

API Endpoints

The API is hosted on stackoverflow-clone-api.onrender.com and stackoverflow-clone-backend.herokuapp.com. Here are some of the essential functionalities:

• Users:
  • GET auth
  • POST auth
  • POST users/:id
  • GET users
• Posts:
  • GET posts
  • POST posts
  • DELETE posts/:id
• Answers:
  • GET posts/:id/answers
  • POST posts/:id/answers
  • DELETE posts/:id/answers
• Comments:
  • GET posts/:id/comments
  • POST posts/:id/comments
  • DELETE posts/:id/comments
• Tags:
  • GET tags
  • GET tags/:tag_name

Troubleshooting Tips

Here are some common pitfalls and solutions when setting up your Stack Overflow clone:

• Database Connection Issues:
  Ensure that your database configurations in the .env file match the database you created in your MySQL client.
• Port Already in Use:
  Make sure no other services are running on port 5000. You can change the port in the relevant files or check what is currently using that port.
• Postman Configuration:
  If using Postman, ensure your environment variable for URL is set to http://localhost:5000.
• Error Messages:
  Check your logs for any error messages and confirm that the packages installed correctly.
