Property does not exist on type 'Window & typeof globalThis'. Even though it is defined in definition file

This is global.d.ts

interface Window {
  routes: any;
  routeMaker: any;
  store: any;
  searchKey: string;
}

As far as I understand, anything is global.d.ts is essentially the same as

declare global {
  interface Window {
    routes: any;
    routeMaker: any;
    store: any;
    searchKey: string;
  }
}

Sitting in root, is the tsconfig.json in which I have pointed to the defination files..

{
  "compilerOptions": {
    "target": "es6",
    "declaration": false,
    "emitDecoratorMetadata": true,
    "baseUrl": ".",
    "experimentalDecorators": true,
    "lib": ["es6", "dom", "webworker"],
    "module": "es6",
    "moduleResolution": "node",
    "sourceMap": true,
    "jsx": "react",
    "typeRoots": ["node_modules/@types", "types"],
    "types": ["node", "webpack-env"],
    "downlevelIteration": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true
  },
  "exclude": ["**/*.spec.js", "node_modules", "vendor", "public"],
  "include": [
    "types/global.d.ts",
    "**/*.d.ts",
    "app/client/src",
    "app/*.ts"
  ],
  "compileOnSave": false
}

The include section points the definition file.

But when I use any props defined in the definition file..

window.routeMaker = {};

Property 'routeMaker' does not exist on type 'Window & typeof globalThis'.

What causes this? And how is this fixed?

You need to add at least one import or one export in order to make global.d.ts an external module to have a global scope effect, so in your case you can do the following:

declare global {
  interface Window {
    routes: any;
    routeMaker: any;
    store: any;
    searchKey: string;
  }
}
export {};
