An important part of web applications is how they route incoming requests to appropriate request handlers. This post details how I implemented Pellet’s first routing system, with room to grow in the future, whilst staying consistent with Pellet’s wider design goals of being fast, concise, and correct. Like the last post, it includes lots of code samples to help you follow along 🧑‍💻.

This post is about building a logging system for Pellet - an opinionated Kotlin web framework I’m working on, with the intention to build best-practices in from the start. I’ll discuss features I think a good logging system should have, introduce the concept of “structured logging”, and talk about implementing everything (with plenty of code examples along the way) 🚀.

This post is about laying some foundations, to help make the Pellet project a success. I’ll talk about prototyping APIs and testing ideas out, to make sure the end result is pleasant to use; integration and load testing, to make sure the project is fast and stable; and finally, I’ll finish up with some work on a “buffer pool” that I’ve been experimenting with, which is a more specific kind of performance improvement.

Pellet is a new, experimental, open-source, Kotlin-based web framework I’m working on. I’ve used numerous web frameworks in various languages over the years, and want to better understand the advantages and disadvantages of their choices — from the perspective of both their internal architecture and their developer-facing APIs.
