Server-Sent Events (SSE) Example with Golang

This repository contains a simple Golang application demonstrating how to implement Server-Sent Events (SSE) without using any web frameworks. SSE enables real-time updates from the server to the client without continuous polling.

Features

  • Provides a basic HTML page with a button that triggers SSE events when clicked.
  • Sends server-generated events to connected clients when the button is clicked.
  • Demonstrates SSE communication using vanilla Go HTTP.

Usage

  1. Clone the repository: git clone https://github.com/phuongdanh/golang-sse.git
  2. Navigate to the repository directory: cd golang-sse
  3. Run the application: go run main.go
  4. Access the application in your browser at http://localhost:8080.

How It Works

  1. When you access the application in your browser, you'll see a button labeled "Send Event".
  2. Clicking the button triggers a POST request to the server, which sends an SSE event with a timestamp to all connected clients.
  3. The client-side JavaScript establishes an SSE connection to the server and displays the received events in real-time.

Requirements

  • Go (Golang) must be installed on your system.
