How to properly export TypeScript methods in node.js app

Question

In my node.js app, I have a TypeScript file (util.ts) that defines methods:

export function myFunc() { console.log(42); }

And I use it in another typescript file:

const util = require('./util');
util.myFunc();

This works fine, but the type of util const is any . How can I make it typed, in a way that when I type util. , my editor will know how to auto-complete, and when I write:

util.myOtherFunc();

TypeScript compiler will fail and say that util doesn't have a myOtherFunc method?

Answer 1

How can I make it typed

Instead of :

const util = require('./util');

Do :

import util = require('./util');
