Zacatl is an open-source TypeScript framework for modular APIs. It keeps application and domain code separate from server and database integrations, with dependency injection, validation, and replaceable adapters.
What does Zacatl provide?
Keep business rules outside HTTP and persistence code. The public repository documents available modules, examples, and current releases.

- Dependency injection and validation
- Replaceable server and database adapters
How is Zacatl verified?
The public repository documents tests, coverage, and CI checks. See the current README and releases for measurements and requirements that can change between versions.
Why use adapters?
Ports describe what an application needs; adapters connect them to a server or database. This keeps integration choices visible and easier to change.
