WEBMIDI.js v3 is available now!

After a lot of work and testing, I am happy to announce today that version 3 of the go-to MIDI
library for JavaScript has been released! You can try it out right
now!

About WEBMIDI.js​

WEBMIDI.js exists to make it easier for developers to use the
Web MIDI API. The Web MIDI API is a really exciting
addition to the web platform allowing a web page to interact directly with MIDI musical instruments
and devices.

While great, many developers will find the API to be too low-level for their needs. Having to
perform binary arithmetic or needing to constantly refer to the 300-page MIDI spec is no fun (trust
me on this!). So, the goal for WEBMIDI.js is to get developers and
musicians started with their web-based MIDI projects as efficiently as possible.

As of today, WEBMIDI.js generates over 744K hits a month on
jsDelivr. It is downloaded over 4.4K times a
month on NPM and has been starred by over
1000 developers on GitHub. Not too bad for a niche
library that grew out of a personal passion project. 😀

About the New Version 3​

Version 3 has been rewritten from scratch to make it both future-proof and backwards-compatible. It
uses a modern development paradigm and now has its own dedicated website at
webmidijs.org. The library offers numerous new features such as:

• Long-awaited support for Node.js (thanks to the jzz
  module by Jazz-Soft). The exact same code can be used in supported browsers and in Node.js.

• Distribution in 3 flavours: ESM (ECMAScript module for modern browsers), CJS (CommonJS
  module for Node.js) and IIFE (Immediately Invoked Function Expression for legacy browsers and
  ad hoc usage).

• TypeScript Support. Every new release includes a TypeScript definition file for CJS and ESM in
  the dist directory.

• New InputChannel and OutputChannel objects. You can now work with a single MIDI channel if
  that’s appropriate for your needs.

• New Note object. Makes it easier to work with notes and pass them around from one method to
  the next.

• New Message object that allows easier routing of MIDI messages, including the ability to
  automatically forward inbound MIDI messages to one, or more, outputs (much like the good ol’
  physical THRU port).

• Improved support for system exclusive (sysex) messages.

• Support for promises while preserving legacy callback support.

• Improved support for RPN/NRPN messages.

• Addition of hundreds of unit tests to make sure the library remains stable at all times.

• and lots more…

Try it out!​

The documentation section of the new website has all the information
to get you started. If you need help, you can exchange with fellow users and myself using the
GitHub Discussions platform.

If you use the library and find it useful, please think about
sponsoring 💜 the project.

Cheers!
