Prologue is a web framework, a toolkit for building websites and web services, written in the Nim programming language. If you've heard of frameworks like Flask or Express, this serves a similar purpose: it handles the common plumbing that every web app needs, so you can focus on your business logic instead of reinventing the wheel. At its core, Prologue lets you define what happens when someone visits a URL on your site. You write functions that take a request (like "GET /hello/Alice") and return a response (like "Hello, Alice!"). The framework routes incoming traffic to the right function, handles things like cookies and sessions, protects against common security attacks, and serves static files like images and CSS. It also supports middleware, mini-programs that can inspect or modify requests before they reach your main code. The main appeal of Prologue is that it's built on Nim, a language designed for speed and efficiency. Unlike some web frameworks that prioritize ease of learning, Prologue emphasizes reducing "magic", unclear behind-the-scenes behavior, so you have more control and predictability. It includes features you'd expect: form handling, data validation, CORS support, authentication, caching, and even i18n (multi-language support). The README shows that a basic "Hello World" web server takes just a few lines of code. You'd use this if you're comfortable with Nim (or willing to learn it) and want to build fast, reliable web services without unnecessary complexity. The repo includes examples ranging from a simple hello-world app to a to-do list and blog, suggesting it's suitable for both small experiments and real projects. If you're already invested in the Nim ecosystem or drawn to its philosophy of explicit, performant code, Prologue is worth exploring.
