Project Walkthrough Overview

Code Genie projects are monorepos that include everything you need to deploy a full stack, Serverless, Cloud Native application.

All packages are written using Typescript and Node.js. Packages for the frontend, backend, infrastructure (IAC), and other supporting packages exist within the top-level /packages directory.

This guide walks you through the source code of a Code Genie project so that you can quickly start building your application.
