Syllabus

Introduction

In this module, we will introduce you to NestJS, a powerful framework for building scalable Node.js applications. You'll learn how to set up your first project and navigate the essential project structure. This foundational knowledge sets the stage for mastering advanced NestJS concepts.

NestJS Fundamentals

In this module, we will dive deep into NestJS controllers, the backbone of routing and request handling. You will learn to handle diverse HTTP methods, manage headers, work with parameters and queries, and control HTTP responses for building robust APIs.

Working with Pipes

In this module, we will explore NestJS pipes, focusing on data transformation and validation. You'll master built-in pipes and develop custom pipes tailored to your application's requirements. Additionally, you'll learn how to apply pipes globally to streamline data handling.

NestJS Middleware

In this module, we will focus on NestJS middleware, a critical piece for pre-processing requests and modifying responses. You will create, configure, and strategically apply middleware to optimize request handling in your application.

NestJS Guards

In this module, we will introduce you to guards, NestJS’s way to protect routes and resources. You will learn to build and combine guards to implement sophisticated access control, ensuring your application remains secure and compliant.

NestJS Interceptors

In this module, we will explore NestJS interceptors, powerful tools to manipulate data flow and enhance request-response handling. You'll learn to create interceptors for tasks such as data transformation, header modification, and exception mapping.

NestJS With MySQL

In this module, we will integrate MySQL with NestJS using TypeORM. You will learn how to connect to databases, create entities, and implement full CRUD functionalities, enabling robust data management for your applications.

Practical Application - Creating a MyStore App

In this module, we will build a practical MyStore app from scratch. You will apply templating techniques, create dynamic interfaces, and configure routes to manage products effectively, reinforcing your understanding through hands-on project development.

Attaching Templates to MySQL

In this module, we will connect your MyStore app’s templates to the MySQL database. You will learn to seamlessly add, update, and delete product data, enabling real-time dynamic content rendering driven by your database.

MyStore - Authentication/Session Cookie

In this module, we will cover user authentication and session management for the MyStore app. You’ll build secure sign-up and login functionalities, manage sessions with cookies, and implement JWT-based authorization for a safe user experience.

NestJS With MongoDB & Mongoose

In this module, we will integrate MongoDB with NestJS through Mongoose. You will learn to create schemas, register them, and manage documents with CRUD operations, enabling flexible NoSQL data management within your NestJS projects.

MyStore With MongoDB & Mongoose

In this module, we will extend the MyStore app by connecting it to MongoDB using Mongoose. You’ll design schemas for users and products and implement session storage with MongoDB to maintain stateful user experiences.
