Discover the power of Server-Sent Events (SSE) with this Golang application. Dive into SSE implementation without relying on frameworks. Experience real-time communication through interactive button-triggered events. An educational resource for learning SSE in a minimalistic Go environment.

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.
