Backend Application Development

Building a backend application often begins with designing a RESTful API using Express.js, a fast and minimal web framework for Node.js. REST (Representational State Transfer) provides a structured way of designing APIs, where resources are represented with endpoints and standard HTTP methods—GET for retrieving data, POST for creating new data, PUT/PATCH for updating existing data, and DELETE for removal. Express makes this process straightforward by offering simple methods to define routes, handle requests, and send responses. Middleware in Express can also be used to process data, log activity, or handle errors, making the development flow more modular.

Once the core API is built, the next step is ensuring the application is secure. Security involves protecting the API from common threats such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Developers often use tools like Helmet.js to set secure HTTP headers, bcrypt for password hashing, and JSON Web Tokens (JWT) or OAuth for authentication and authorization. Validating user input, enforcing HTTPS, and rate limiting requests are additional best practices to reduce vulnerabilities and prevent misuse.

After development and securing the application, the final stage is deployment. Backend applications built with Express.js can be deployed on various platforms such as cloud services (AWS, Google Cloud, Azure), containerized environments using Docker, or platform-as-a-service providers like Heroku and Vercel. Deployment usually involves setting environment variables, connecting to production databases, and configuring process managers like PM2 to ensure the application runs continuously and can recover from crashes. Load balancers and scaling strategies are also applied to handle high traffic and maintain performance.

In short, RESTful API development with Express.js provides the foundation for handling client-server communication, securing the backend ensures reliability and protection against attacks, and deploying the application makes it accessible to real users in production environments. Together, these steps form the backbone of modern backend development.



Window Server Administration

This module equips learners with practical skills to administer and manage Windows Server environments. It focuses on three key outcomes:

1. Manage Server Services

  • Students learn how to install, configure, and monitor core server services such as DNS, DHCP, and File/Print services
  • Emphasis is placed on starting, stopping, and troubleshooting services to ensure availability and performance.

2. Manage Users

  • Learners practice creating and managing user accounts, groups, and organizational units using Active Directory.

  • They explore permission assignment, password policies, and access control to secure resources and maintain user productivity.

3. Deploy Web Applications

  • Students are introduced to Internet Information Services (IIS) for hosting and deploying web applications.

  • They configure websites, virtual directories, and application pools, ensuring applications run securely and efficiently on the server.

By the end of the module, learners gain the ability to administer server resources, control user access, and support organizational needs through reliable service management and web application deployment.
