Primary LanguageJava

Spring Boot Websocket + React: user notifications with web socket

This example will show how to send notifications, via web socket, to specific logged-in users (definded by access_token).

Could be useful, for example, if you are trying to implement a real-time user notification system with ReactJS.

DEMO:

Demo

Build and run

Configurations

Backend:

Open the application.properties file in websocket-spring and set your own database (in my case I'm using MongoDB). You can change User collect to Entity and repository like your project.

Prerequisites

  • Java 8
  • Maven > 3.0

From terminal

  1. Start mongodb database 
    $ mongod
  2. Go on the project's websocket-spring folder, then type: 
    $ mvn spring-boot:run
    Or, just open Maven project on IDE like IntelliJ IDEA and run main method in Application class
  3. Go on project:s websocket-react folder, then type: 
    $ npm install
$ npm start
    or 
    $ yarn install
$ yarn start

Usage

  • Launch the application and login into it with one of the following credentials (Username / Password):

    • user1 / user1
    • user2 / user2

  • Keep a window open on the index and login by user1

  • Open a new private/incognito windows of your web browser and login with user2

  • From this web browser specify target user and click the button to send a fake action: target user will be notified.
