Avi.js tutorial

This tutorial teaches Avi.js by building a small API, one concept per chapter. It is written for Node.js and TypeScript developers who know Express. NestJS experience helps but is not required.

Every chapter runs with the published packages. Start with chapter 0 to create a project, then follow the chapters in order or jump to what you need.
