Syllabus

Case Study 1- E-commerce Application
- This module guides learners through building a scalable e-commerce application using NestJS, focusing on designing RESTful APIs, integrating PostgreSQL, and implementing core business logic for products and orders. Learners will also address non-functional requirements, set up authentication, and apply best practices for modular architecture and exception handling.
Case Study 2- Social Networking Platform
- This module guides learners through designing and implementing GraphQL APIs for a social networking platform, including user, post, and reaction management. You will explore NoSQL database structures and learn how to enable real-time updates and notifications to enhance user engagement. By the end, you'll gain practical experience building scalable, interactive social features.
Case Study 3 – Enterprise Resource Planning System
- This module guides learners through the design and implementation of an enterprise resource planning (ERP) system using NestJS, with a focus on microservices architecture, scalability, and data consistency. Learners will explore high-level system architecture, develop core modules, implement security best practices, and apply advanced patterns like Saga for workflow management. Practical exercises include Dockerizing microservices and orchestrating business processes across multiple services.
Deploying NestJS Applications
- This module guides you through the process of deploying NestJS applications using Docker, configuring cloud environments, and implementing essential monitoring and security practices. You will learn how to transition your application from local development to a scalable, production-ready service. Ongoing maintenance and optimization strategies are also covered to ensure long-term reliability.
Embracing DevOps: Continuous Integration and Continuous Deployment for NestJS
- This module guides learners through the essentials of implementing Continuous Integration and Continuous Deployment (CI/CD) for NestJS applications. You will discover how to automate testing and deployment using GitHub Actions, and learn best practices to ensure efficient, reliable, and scalable software delivery.
NestJS Performance Optimization
- This module guides learners through essential techniques for boosting the performance of NestJS applications, including code optimization, efficient database querying, and effective caching strategies. Participants will also gain hands-on experience with profiling and load testing to identify and address performance bottlenecks.
NestJS Security Best Practices
- This module guides learners through essential security practices for NestJS applications, including safeguarding data in transit, implementing robust access controls, and defending against common threats like man-in-the-middle attacks. By mastering these strategies, learners will enhance the resilience and trustworthiness of their applications.
