The @babel/runtime package is a library that includes Babel modular runtime helpers and a version of regenerator-runtime. It is used to avoid polluting the global scope and to reduce the size of the compiled output by deduplicating helper functions that are commonly used by Babel-transpiled code. It is particularly useful when building libraries or applications that need to be optimized for size and scope isolation.

What are @babel/runtime's main functionalities?

Modularized Helpers

This feature allows you to use Babel's helper functions in a modular way, without including them in every file that needs them, thus reducing redundancy and file size.

import _classCallCheck from '@babel/runtime/helpers/classCallCheck';

class MyClass {
  constructor() {
    _classCallCheck(this, MyClass);
    // class body
  }
}

Regenerator Runtime

Includes a version of the regenerator runtime to enable the use of async/await and generator functions in environments that do not natively support them.

import 'regenerator-runtime/runtime';

async function asyncCall() {
  await someAsyncFunction();
}
