Package description

What is @babel/plugin-transform-runtime?

The @babel/plugin-transform-runtime package is a Babel plugin that enables the re-use of Babel's injected helper code to save on codesize. It also allows you to use built-ins such as Promise or WeakMap, static methods like Array.from or Object.assign, instance methods like Array.prototype.includes, and generator functions in environments that do not natively support them.

What are @babel/plugin-transform-runtime's main functionalities?

Helpers

This feature allows Babel to transform code by extracting common helper functions into shared modules to reduce code duplication in the output.

"use strict";\n\nfunction _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError(\"Cannot call a class as a function\"); } }\n\nvar Foo = function Foo() {\n  _classCallCheck(this, Foo);\n};

Polyfills for instance methods

This feature enables the use of instance methods like 'includes' on arrays, which are part of the ECMAScript specifications but may not be available in all environments.

import \"core-js/stable\";\nimport \"regenerator-runtime/runtime\";\n\n[1, 2, 3].includes(2);

Built-ins

This feature allows the use of new built-in objects like Promise, which are part of the ECMAScript specifications but may not be natively supported in all environments.

import \"core-js/stable\";\nimport \"regenerator-runtime/runtime\";\n\nvar promise = new Promise();

Generator functions

This feature allows the use of generator functions, which can be used to perform asynchronous operations in a synchronous-like manner.

import \"core-js/stable\";\nimport \"regenerator-runtime/runtime\";\n\nfunction* aGenerator() {\n  yield 1;\n  yield 2;\n  yield 3;\n}
