How to include a typescript file for files in specific folder without import?

Somehow I need to include a d.ts file for every files in a specify folder while not polluting other files' global namespace, how can I achieve this without import(there is lots of typing in that d.ts) or triple slash(this is disabled by eslint)?

It imports some typing from dependencies so simply include it won't have any effect

Best practice to do this is define typeRoots property in tsconfig.json:

"typeRoots": [
  "src/@types",
  "node_modules/@types"
]

And in src/@types directory add custom .d.ts files look like below:

// in src/@types/scss.d.ts
declare module '*.scss' {
  const styles: { [className: string]: string };
  export default styles;
}

In your tsconfig.json, you can add the include property and add a reference to the files you want included. E.g. 

"include": [
    "./src/**/*.ts",
    "./definitions/**/*.d.ts"
  ]

This is not going to create a dependency, or import the file in your project, but will look for the types inside it, same way as the triple slash method.
