TCP Communication with Node.js

A TCP server and client implementation using Node.js's net module, operating at the Transport Layer of the OSI Model.

This implementation focuses on direct communication without additional overhead such as data compression or encryption/decryption, suitable for safe and trusted networks.

The TLS variant (@Presentation-Layer of the OSI Model) is located here: Node-TLS

Some Use Cases:

• Network Diagnostics

  Test network connectivity and latency between network segments.

• Embedded Systems Communication

  Integrate TCP client with embedded devices (e.g. Raspberry Pi, Arduino with Ethernet/Wi-Fi shields) to send data to a central server (for monitoring and control).

• Time Synchronization

  Use the server to provide a timestamp service for devices on a network (ensure synchronized time across various systems).

• IoT Apps

  Use the TCP server as a central hub to collect data from various IoT devices.

  Set up the TCP client to send sensor data periodically from remote IoT devices to the server for analysis (centralized data receiver/logger).

Quick Start:

Server:

npm install
node tcpServer.js   # Runs Server

Client:

npm install
node tcpClient.js   # Runs Client

Logs and Outputs:

The server and client will log various server/client events and actions, such as connection establishment, data transmission, and encountered errors.
