Supported Environments

Starting with version 3, the library works in both the browser and Node.js. Let's quickly look at the specificities of both these environments.

Browser Support​

The library works in all browsers that natively support the Web MIDI API. Currently, the following major browsers have native support:

  • Edge v79+
  • Chrome 43+
  • Opera 30+
  • Firefox 108+

It is also possible to use this library in other browsers if you install Jazz-Plugin v1.4+. This combination provides support for the following additional web browsers:

  • Safari
  • Internet Explorer

Note that, in 2020, Apple has announced that they would not natively support the Web MIDI API (and a host of other APIs) in Safari because of fingerprinting concerns.

Node.js Support​

Version 3.0 of WEBMIDI.js introduced full Node.js support. Nothing special needs to be done, it should just work in the following environments (with Node.js 8.5+):

  • GNU/Linux
  • macOS
  • Windows
  • Raspberry Pi

Support for the Node.js environment has been made possible in large part by the good folks of Jazz-Soft via their JZZ module.

TypeScript Support​

Starting with version 3, TypeScript is officially supported. You will find the TypeScript definition file in these locations in side tje library's folder:

  • /dist/cjs/webmidi.cjs.d.ts (Node.js module)
  • /dist/esm/webmidi.esm.d.ts (ECMAScript module)
