Building a Web App in Swift Using Only SwiftNIO

This article details an experiment in building a basic web application using only SwiftNIO, Apple's open-source asynchronous event-driven network framework, without relying on higher-level frameworks like Vapor. The author explains the motivation behind the project, sets up a TCP server using ServerBootstrap, and implements custom HTTPHandler classes for connection handling. The guide includes code examples for configuring server channels, enabling port reuse, and setting up HTTP/1.1 pipelines. The project is fully commented and available on GitHub for readers to explore and modify. This is a technical tutorial focused on Swift web development and low-level networking.
