In Elixir I love to use the library [GitHub - sasa1977/boundary: Manage and restrain cross-module dependencies in Elixir projects](https://github.com/sasa1977/boundary) to enforce boundaries between modules and keep “areas” (aka boundaries) from reaching into the guts of another area.

Does anyone know of any similar library or approach for frontend typescript code? I’ve been having trouble searching because I don’t know of a good name for this type of library and I’m not familiar with any besides Boundary.

Found one library that looks promising: [GitHub - sverweij/dependency-cruiser: Validate and visualize dependencies. Your rules. JavaScript, TypeScript, CoffeeScript. ES6, CommonJS, AMD.](https://github.com/sverweij/dependency-cruiser)
