Reactive Applications with Spring WebFlux Framework

Overview

Creating a Secure, Reactive and non-blocking REST API with Spring WebFlux

What you'll learn:

What Reactive Programming is
Architecture of Reactive Spring Boot application
Create Reactive Spring Boot application
Write and read from a database in reactive/non-blocking way
Use Spring Security in reactive Spring WebFlux application
Implement user authentication in reactive application
Implement JWT authentication in reactive application
Create and validate JSON Web Tokens(JWT)
Use method-level security annotations
Write Spring Security Expressions(SpEL)

In this video course you will learn how to create Reactive and Non-blocking applications with Spring WebFlux framework.

This course is perfect for beginners and will start with the basics of Spring WebFlux.

You will learn:

- What Reactive programming is and how it is different from an imperative programming style,

- The key differences between the traditional, blocking Spring WebMVC and the non-blocking, Reactive Spring WebFlux applications,

- To create reactive RESTful Web Service application that handles different types of HTTPrequests,

- Write and read information from a database in a reactive, non-blocking way.

As you progress through the course, you will learn how to:

- Use Spring Security to protect your Spring WebFlux application,

- Implement user login(authentication),

- Generate and use JSON Web Tokens (JWT) for secure communication

- Validate JWTand read token claims,

- Use method-level security annotations to perform authorization.

You will also learn how to add pagination and read database records in smaller chunks to improve performance.

All important concepts are explained using simple, easy-to-follow slides. The source code is provided, so you can download it and follow along with each lesson.

This course also includes helpful quiz questions to test your knowledge as you go. Plus, there is an active Q&A section where you can get answers to all your questions

By the end of this course, you’ll be able to create fast, secure, and scalable Reactive applications with Spring WebFlux.
