Fix: Move MongoDB URI to Environment Variables

[Aryan3522]

The MongoDB connection URI is currently hardcoded in the codebase. This should be moved to an environment variable to improve security and follow best practices.

Task

• Remove the hardcoded MongoDB URI from the source code.

• Store the URI inside the .env file.

• Update the database connection logic to use the environment variable.

Example:

process.env.MONGODB_URI

Expected Outcome

• MongoDB credentials are no longer exposed in the codebase.

• The application reads the database connection string from environment variables.

Summary

Removed the hardcoded MongoDB connection string from the source code and replaced it with an environment-based configuration.

Changes

• Updated Config/db.js to use mongoose.connect(process.env.MONGODB_URI)
• Renamed environment variable from MONGO_URL to MONGODB_URI
• Updated test scripts (test-db*.js) to use process.env.MONGODB_URI
• Added require("dotenv").config({ path: "./Config/config.env" }) where required
• Added Config/.env.example with placeholder values
• Updated .gitignore to prevent committing the real environment configuration file

Result

The MongoDB URI is no longer hardcoded in the repository.
All database connections now use environment variables, improving security and configuration management.
