Typescript prevent imports from certain directory in project

A few ideas based on some quick online research:

1. good-fences is a dedicated tool to restrict imports in a TypeScript project. You'd have to add it to your build process as a separate step.
2. Compile your TypeScript code with module set to es6 (to a separate output directory if you need a different module setting to generate the code you actually run) and then run ESLint with the no-restricted-imports rule on the output.
3. Set up both your runtime environment and your tsconfig.json so that you can use only non-relative imports, and then use the no-relative-imports rule from tslint-microsoft-contrib. However, there was talk of deprecating no-relative-imports.
4. Write your own TSLint-based reimplementation of ESLint's no-restricted-imports and contribute it to tslint-eslint-rules.

It sounds like Dependency Cruiser is the tool you're looking for. You can put together any arbitrary rules you want with it, run it during your build process, and it'll automatically report dependency violations. It supports typescript, javascript, commonjs, es6 modules, and more.

I've actually been looking for an answer to this exact question for a while, and it wasn't until recently that I've stumbled upon this tool. Hopefully others can find it useful too.
