NOTE: This plugin is included in @babel/preset-env, in ES2020

Syntax only

This plugin only enables parsing of this feature. Babel doesn't support transforming BigInts. One recommendation is to use the JSBI library and eventually run babel-plugin-transform-jsbi-to-bigint to codemod it to BigInt in the future.

Installation

npm install --save-dev @babel/plugin-syntax-bigint

Usage

With a configuration file (Recommended)

{
  "plugins": ["@babel/plugin-syntax-bigint"]
}

Via CLI

babel --plugins @babel/plugin-syntax-bigint script.js

Via Node API

require("@babel/core").transformSync("code", {
  plugins: ["@babel/plugin-syntax-bigint"],
});
