Convert to/from ES-2020 native JS implementation of BigInt from/to:

• Buffer (node.js) or ArrayBuffer|TypedArray (native js),
• hex string,
• utf8-encoded text string.

It provides a common interface for the conversions that works for both node.js and native javascript.

Note that there is not a directly visible TypedArray() constructor, but a set of typed array ones: Int8Array(), Uint8Array(), Uint8ClampedArray(), Int16Array(), Uint16Array(), Int32Array(), Uint32Array(), Float32Array(), Float64Array(), BigInt64Array(), BigUint64Array().

bigint-conversion is distributed for web browsers and/or webviews supporting BigInt as an ES6 module or an IIFE file; and for Node.js as a CJS module.

bigint-conversion can be imported to your project with npm:

npm install bigint-conversion

NPM installation defaults to the ES6 module for browsers and the CJS one for Node.js. For web browsers, you can also directly download the IIFE bundle or the ESM bundle from the repository.

Import your module as :

• Node.js

  const bigintConversion = require('bigint-conversion')
  ... // your code here

• JavaScript native or TypeScript project

  import * as bigintConversion from 'bigint-conversion'
  ... // your code here

  BigInt is ES-2020. In order to use it with TypeScript you should set lib (and probably also target and module) to esnext in tsconfig.json.

• JavaScript native browser ES6 mod

  <script type="module">
     import * as bigintConversion from 'lib/index.browser.bundle.mod.js'  // Use you actual path to the broser mod bundle
     ... // your code here
   </script>

• JavaScript native browser IIFE

  <script src="../../lib/index.browser.bundle.iife.js"></script> <!-- Use you actual path to the browser bundle -->
  <script>
    ... // your code here
  </script>
