Publish your npm package as ES Module, and backward compatibility CommonJS

Create your library

  • Initialize project npm init -y
  • Create esm module ./src/esm/my-lib.js 
    function addNumber(value, value2) {
  return value + value2;
}

export { addNumber };

stevendesu / HMAC.js
Created April 30, 2020 16:18
A simple, open-source, HMAC-SHA256 implementation in pure JavaScript. Designed for efficient minification.
// To ensure cross-browser support even without a proper SubtleCrypto
// impelmentation (or without access to the impelmentation, as is the case with
// Chrome loaded over HTTP instead of HTTPS), this library can create SHA-256
// HMAC signatures using nothing but raw JavaScript
/* eslint-disable no-magic-numbers, id-length, no-param-reassign, new-cap */
// By giving internal functions names that we can mangle, future calls to
// them are reduced to a single byte (minor space savings in minified file)
