Backend for Customer Management System

Imagine you are tasked with setting up a backend for a customer management system. The system's database is hosted on MongoDB, and you need to create a Node.js server using Express.js to interact with the database. Your job is to set up the server, connect it to MongoDB atlas, and ensure the connection status is logged appropriately.

Instructions:

Initialize the Project:

Basic express template was given
You need to install all the necessary packages required for the task.

Environment Configuration:

• Set up a .env file in the root directory.
• Store the MongoDB connection string securely in the .env file.
• The connection string must follow the format: MONGO_URI=mongodb+srv://<username>:<password>@cluster0.mongodb.net<databaseName>?retryWrites=true&w=majority

Backend Server Requirements:

• Go to index.js.
• Set up an Express.js server.
• Write the code to:
  • Load and use environment variables from the .env file.
  • Connect to MongoDB using a database library.

Logging Requirements:

• On a successful connection to the database, the server should log the following message: Connected to database
• If the connection fails, the server should log the following error message along with details of the error: Error connecting to database: <Error details>

Testing the Backend:

• Start the server and test the connection to MongoDB.
• Ensure appropriate messages are logged based on the connection status.

  • Option 1: Download and Push
    1. Download the repository files from StackBlitz.
    2. Open your terminal/command prompt, navigate to the project folder, and run:

       git init
       git remote add origin <your_github_repo_url>

       Replace <your_github_repo_url> with your personal GitHub repository URL.
    3. Commit and push the files to your GitHub repository:

       git add .
       git commit -m "Completed the assignment"
       git push -u origin main

  • Option 2: Push Directly
    1. Use the Push to GitHub option in StackBlitz to directly connect and push the repository to your GitHub account.

3. Submission Instructions

• Once your code is successfully pushed to GitHub:
  1. Copy the link to your GitHub repository.
  2. Submit the link on the assignment submission portal.
     The link should follow this format:
     https://github.com/<your_username>/<repository_name>
