Types for global variables

I have defined a global variable: globalThis.Args = validateArguments(Deno.args); Now whenever I use it I get TS error: Element implicitly has an 'any' type because type 'typeof globalThis' has no index signature.deno-ts(7017) How can I fix this?

Hi. Try to create a new d.ts file like global.d.ts with the contents

// deno-lint-ignore no-var
declare var Args: Record<string, unknown>;

// deno-lint-ignore no-var
declare var Args: Record<string, unknown>;

Add a reference to this d.ts file in the compiler options in deno.json

{
  //...
  "compilerOptions": {
    "types": ["./global.d.ts"]
  },
  //...
}

{
  //...
  "compilerOptions": {
    "types": ["./global.d.ts"]
  },
  //...
}

You should be able to access Args from globalThis this should also pass the deno check command to typecheck your code
