[SOLVED] With tsconfig.json, is there in option to have stricted settings for some of the files?

With tsconfig.json, is there in option to have stricted settings for some of the files?

here is my tsconfig.json:

{
  "compilerOptions": {
    "allowArbitraryExtensions":true,
    "target": "ES2021",
    "lib": [
       "ES2021", "dom", "dom.iterable"
    ],
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "strictFunctionTypes": true
    
  },
  "lib": ["ES2021"],
  "exclude": ["node_modules", "dist","tmp"]
}

This works fine for me, but i would like to have stricter rules for subset of my project. chiefly "noImplicitAny": true,

Is it at all possible?

Solution

This is possible:

Define another tsconfig.json is the said subfolder.

{
  "extends": "../../../tsconfig.json", //To have the same rules as the main project
  "compilerOptions": {
    "noImplicitAny": true, //extra rules
  },
  "include": ["*"]
}

Just make sure you extend it correctly. We want extension to work so that this subfolder follows all the rules of the main project and overrides only the essential ones.
