mitt VS tonal

Mitt is a small (200 bytes) library that provides the same functionality. It doesn't have many updates, because it's simply perfect and there are not many things to improve there. It gets the job done. Don't be frightened, if in 2 years npm will say it's 2 years old. This library is just perfect with no bloatware. In the worst case, just copy-paste its code to your app.

The implementation can vary widely depending on the requirements. For our application, we will take a small library that will do almost everything for us:

You can use an event bus for this, looks like they removed this functionally from vue 3 so you'll need a 3rd party package like mitt

then we need to install an external library implementing the event emitter interface, in this case mitt

date-fns and mitt (event emitter) are also frequent helpers, but I'm considering dayjs and nanoevents for these cases.

Not sure I understood the post right, bit you may want to check Mitt. It's popular event emitter package that quite nicely deals with this very issue.

As suggested in official docs you could use mitt library to dispatch events across components.

You can use it mitt library. https://github.com/developit/mitt

For situations like this, I use simple event emitter / pubsub library called mitt. It's small and lightweight, however there are many similar libraries that would work.

In this article I want to show you how I have implemented this pattern in my Nuxt 3 applications using Mitt which already provides full TypeScript support. To fully understand what's happening under the hood I recommend to have a quick read of Mitt documentation before continue reading.

They're using objects, including arrays [1], so I think they would have been more precise to say that they're using objects and arrays as simple data structures rather than using OO features like inheritance and mutation.

It's not on this list, but it's a cool list to check out either way

I'm working on a music project and both tonejs and tonal are incredible projects.

Regarding the "Music Theory library" aspect, note that the CLI tool demonstrates use of the underlying Ruby library which has documentation here:

Additionally, the author wrote a post about the motivation for creating the library but it's a little difficult to find via the (now broken) link in the README, so here is a direct link to the archived page on the Wayback Machine:

If anyone is interested in a similar music theory library for Javascript[0] I've had some success with this:

* Tonal / Tonal.js https://github.com/tonaljs/tonal

[0] Or, in a pinch, even with a Godot 4 web export as I did for my (very incomplete) "AI and Games" Game Jam entry: https://rancidbacon.itch.io/the-conductor (For reasons far too convoluted to go into now.)

There are many hundreds of scale types, here's a list of many of them and that's just a single key. Let's say there's 200 scales times 12 for each key, that's 2400 times up and down the piano. There are actually much more than 200 scales though!

I found a module that is perfect for what I'm trying to create, (a simple piano that you can select keys on to find out which chord it gives), and am trying to use https://github.com/tonaljs/tonal .

Agree with the representation, you can really bury yourself in complexity if you're not careful. Have you taken a look at any of the JS libraries like tonal or MusicTheoryJS?

Here's how tonal.js does it: https://github.com/tonaljs/tonal/tree/master/packages

For the music theory stuff I'm using TonalJS along with my own extensions
