The purpose of this project is to demonstrate how we can use Spring WebFlux to create a simple reactive web application.

This project uses PostgreSQL implementation of the R2DBC SPI.

project can be compiled with JDK 8 and above javac.

To compile just do mvn clean package.

• JAVA 8 should be installed
• Postgres should be up and running at : localhost:5432

To run the application execute the following:

java -jar target/reactive-examples*.jar

You can also use the Swagger-UI to test the application.

for more detailed technical information please check my post : https://dassum.medium.com/building-a-reactive-restful-web-service-using-spring-boot-and-postgres-c8e157dbc81d

The server will start at http://localhost:8080.

The Swagger UI will open at : http://localhost:8080/swagger-ui/index.html

The application contains the following REST APIs

1. GET /users - Get All Users

2. POST /users - To create a User

3. GET /users/{userId} - Retrieve an User by Id

3. PUT /users/{userId} - Update an User

4. DELETE /users/{userId} - Delete an User

4. GET /users/events - Stream users to a browser as Server-Sent Events

It contain a sample WebClient to retrieve data from our User Management application.
