Package description

What is regenerator-runtime?

The regenerator-runtime package is a runtime module for Regenerator-compiled generator and async functions. It provides a polyfill for environments that do not natively support these features, allowing developers to use generators and async/await syntax in their JavaScript code.

What are regenerator-runtime's main functionalities?

Generator Function Support

Enables the use of generator functions, which can yield multiple values over time, allowing for more control over asynchronous operations.

function* gen() {
  yield 1;
  yield 2;
  yield 3;
}

const g = gen();
console.log(g.next().value); // 1
console.log(g.next().value); // 2
console.log(g.next().value); // 3

Async/Await Support

Allows the use of async/await syntax for writing asynchronous code in a more synchronous fashion, improving readability and maintainability.

async function fetchData() {
  const data = await fetch('https://api.example.com/data');
  return data.json();
}

fetchData().then(data => console.log(data));

To import the runtime as a module (recommended), either of the following import styles will work:

// CommonJS
const regeneratorRuntime = require("regenerator-runtime");

// ECMAScript 2015
import regeneratorRuntime from "regenerator-runtime";

To ensure that regeneratorRuntime is defined globally, either of the following styles will work:

// CommonJS
require("regenerator-runtime/runtime");
