What sets Import apart from require in TypeScript?

I've been grappling with the nuances between import and require when it comes to using classes/modules from other files. The confusion arises when I try to use require('./config.json') and it works, but

import config from './config.json'
does not.

Could it be that import only accepts classes/modules and cannot work with JSON?

Furthermore, my understanding is that import functions during compile time while require operates at runtime. All of this has left me feeling quite perplexed.

Answer №1

These module systems function in completely different ways.

  • import is part of "ES modules," which are the native JavaScript implementation of modules introduced by ES6.
  • require, on the other hand, is the import mechanism of the commonjs module system. It is still widely used today, especially because Node.js relies on it (as there was no native module system in JavaScript's specification when Node.js was created).

Explore both the import/export documentation on MDN and the require documentation on the Node.js website for more information.
