"review": "**Grade: 7**\n\n### Bugs\n- No specific bugs present in the code snippet, but it heavily depends on a valid `MONGODB_URI` in the environment variables; if not set, it will cause a runtime error.\n\n### Optimizations\n- Consider making `client` connection closed gracefully or reusing it rather than establishing a new connection each time `createConnection` is called.\n- Add error handling for connection failures to manage potential exceptions and avoid application crashes.\n- Consider using a connection pool with a defined size or configuration options for improved performance in high-load scenarios, like using `{ useNewUrlParser: true, useUnifiedTopology: true }`.\n\n### Good Points\n- Uses async/await for handling asynchronous connections, which is a clean and modern approach.\n- Follows a modular approach by encapsulating the creation of the MongoClient connection.\n\n### Summary\nThe code provides a clean and straightforward implementation for creating a connection with MongoDB using the `MongoClient`. It effectively leverages ES6 features like async/await for asynchronous operations. However, it lacks proper error handling and optimizations related to connection reuse and configuration tuning, which could be critical in a production environment.\n\n### Open source alternatives\n- **Mongoose** - An ODM (Object Data Modeling) library for MongoDB and Node.js that provides a higher-level API and additional features like schema validation.\n- **Mongoist** - A simpler, flexible Node.js library for working with MongoDB that simplifies callback and promise handling.",
