TELSSE

This project implements a simple telnet + server-sent events (SSE) application with a terminal-like web interface, utilizing TailwindCSS for styling and Golang for the backend. The application serves a static website and maintains a telnet service for receiving messages, which are then broadcasted in real-time to connected web clients via SSE.

Features

• Static website serving using Golang
• Real-time message broadcasting using Server-Sent Events (SSE)
• Terminal-like interface for message display using TailwindCSS
• Telnet service for receiving messages

Prerequisites

To run this project, you need to have the following installed:

• Golang (version 1.15 or later)
• Node.js and npm (for TailwindCSS)
• godotenv package for Golang

Installation

1. Clone the repository:

git clone https://github.com/nkoster/telsse
cd telsse

2. Install the Go dependencies:

go mod tidy

3. Run the Golang server:

go run main.go

or build a binary, and run the binary telsse

CGO_ENABLED=0 go build -ldflags="-extldflags=-static"
./telsse

Make sure you have configured your .env file. See below in the Configuration section.

Usage

• Open a web browser and navigate to http://localhost:8080 to view the SSE chat interface. Replace 8080 with the actual port number specified in your .env file.
• Use a telnet client to connect to the telnet service and send messages. Replace 5023 with the actual port number specified in your .env file:

telnet localhost 5023

or

tail -f /var/log/nginx/access.log | telnet localhost 5023

• Messages sent via telnet will appear in real-time on the web interface.

Configuration

Create a .env file in the root directory of your project with the following content:

UI=./ui
HTTP_PORT=8080
TELNET_PORT=5023
LOG=false         # when true, telnet lines also appear in the server log
