Key course goals include:

Understanding core concepts:

• Node.js fundamentals (asynchronous programming, event loop, modules)
• Express.js routing, middleware, and application structure
• MongoDB document database structure, querying, and data modeling
  Setting up a development environment:
• Installing Node.js and necessary dependencies
• Creating a basic Express server
• Connecting to a MongoDB database (local or cloud-based)
  Data manipulation with MongoDB:
• Creating, reading, updating, and deleting documents (CRUD operations)
• Implementing complex queries using MongoDB operators
• Data validation and error handling
  Building RESTful APIs with Express:
• Designing API endpoints using HTTP methods (GET, POST, PUT, DELETE)
• Implementing route handlers to process API requests
• Handling data serialization (JSON) and response formatting
  Authentication and authorization:
• Implementing user registration and login functionality
• Managing user sessions and access control
• Securely storing user credentials
  Advanced topics (depending on the course level):
• Middleware for logging, error handling, and request parsing
• Implementing pagination and data filtering
• Scaling applications with MongoDB sharded clusters
• Integrating with other services (like email, payment gateways)
  By the end of a Node, Express, and MongoDB course, students should be able to:
• Build a fully functional web application backend with a database
• Design and implement RESTful APIs using Express
• Interact with a MongoDB database to store and manage application data
• Secure sensitive data and implement user authentication
• Troubleshoot common issues related to Node.js, Express, and MongoDB
