Introduction

Sheriff enforces module boundaries and dependency rules in TypeScript.

• Module boundaries ensure that files within a module are encapsulated, preventing access from outside the module. Modules are defined either via a sheriff.config.ts file or by the presence of a barrel file, like index.ts.

• Dependency rules allow you to specify which modules can depend on one another, enforcing a clear structure throughout your project. Like module boundaries, these rules are defined in the sheriff.config.ts file.

Sheriff has zero external dependencies, with TypeScript as its only peer dependency.
