How to declare a global variable of a module in Typescript?

Question

I have already required a global value to my global javascript context:

const fs = require('fs')

Because of some special reason, I have to require it in the global scope.

And I want to write a .d.ts file to declare the global variable with a strong type.
But how to? 'fs' is a module, not a type.

If I give the type like: (in my types.d.ts file)

import * as fsi from 'fs';
declare const fs: fsi;

There will be an error TS2709: Cannot use namespace 'fsi' as a type.

Answer 1

声明为class对象而不是type

private fsi= new fsi()
