Is it possible to import in TypeScript using only the declaration statement?

Is there a way to use a node module in TypeScript without explicitly importing it after compilation?

For example:
I have a global variable declared in a file named intellisense.ts where I have:

import * as fs from 'fs';

Then in another file, I refer to it like this:

/// <reference path="./intellisense.ts" />
fs.existsSync('...');

However, VSCode intellisense gives an error saying it cannot find the name 'fs'.

Is there a workaround for this issue without importing fs again in the second file?

Please keep in mind:

  • I want fs to be imported only once
  • I prefer not to export fs from intellisense.ts
  • I do not want to import intellisense.ts in any manner
  • I do want to have fs in the global scope as a reference

I declared a variable at a global scope within a file

It seems like you may have mistaken a globally accessible variable for an imported module in the file. Keep in mind that imported modules need to be explicitly imported in every file they are used in.
