This is the dependency injection system used by Biomes. This is one of the best codebase I've ever seen. And partly because of the efficiency and simplicity of their dependency injection framework.
Adding resources was super simple, and their type annotations made working with their framework fantastic. So I wanted to factor out their dependency injection framework into this repo for myself to use if I ever wanted something similar!
Note: If you want to drop this into your project, just copy and paste everything under the dep_inj/ directory into your project.
Look at clicker.tsx to see how simple it is to interact with the clicker. Also look at dep_types.ts (and resources/clicker.ts) to see how the components are declared.
