This is a continuation of this question. I have made a few changes that simplifies the question(I believe) and changes it drastically.

Your hook is async so u need to wait for the next update. Here is the docs that talks more about it.

JS - Calling class methods inside of callback function

Asked 2021-Jan-31 at 17:38

I'm currently having a problem and don't know how to solve it correctly.

I'm developing a web application with js using the WebMidi API.

I want to load all midi devices into a dropdown after WebMidi is loaded. As far as I understood it I have to pass the enable function of Webmidi a callback function:

...

ANSWER

Answered 2021-Jan-31 at 17:38

WebMidi.enable is an asynchronous function, meaning it allows you to specify what to do once WebMidi is enabled. The problem is that you're not using this functionality to full power.

Imagine you're the guy who shoots the gun to start a race: your code is the equivalent of shooting and turning your eyes away from the race but still wanting to know when the race ends. If you want to do something right after the race ends, better look at the race, right?

Right now, the constructor function starts the WebMidi.enable race and immediately tries to fill the dropdown. That's not what you want - you want to fill the dropdown when the race ends.

To resolve your problem, make MidiListener.enable take a callback function that gets executed when WebMidi.enable is done without errors. This will allow you to do something right when WebMidi.enable finishes.

You have various options: then is just a function, so you can just use (.then ..). If the thenable is a Promise object, promesa https://cljdoc.org/d/funcool/promesa/5.1.0/doc/user-guide has a nice interop story.

It's also pretty simple to add some macro syntax sugar around promises, as I've done here: https://gist.github.com/beders/06eeb1d8f49de715c6bd2b84f634cff6

why is requestMIDIAccess working locally but not remote?

Asked 2020-Apr-13 at 21:30

Playing around with this javascript library https://www.w3.org/TR/webmidi/#introduction I got some basic functionality working and I was happily able to send midi notes to my syntheseizer and hear it working!..

However, when I wanted to try out the exact same javascript code, but hosted remotely, I got this error:

navigator.requestMIDIAccess() is only available in a secure context, which means your remote host must serve your resources via HTTPS.

Resources served from localhost are considered to be in a secure context, whether delivered via HTTPS or HTTP.

Connect to your remote host using HTTPS instead of HTTP and that should resolve the problem.

QUESTION

The Web MIDI API is not supported by your browser - Google Chrome on Mac - when code is run locally

Asked 2020-Jan-12 at 02:41

Folks,

I am trying work on a simple Web MIDI app.

I already looked up and found out that Google Chrome is the only browser that supports this. So, I installed this but I still get this.

WebMidi could not be enabled Error: The Web MIDI API is not supported by your browser. at WebMidi.enable (webmidi.min.js:30) at script.js:430 (anonymous) @ script.js:432 WebMidi.enable @ webmidi.min.js:30 (anonymous) @ script.js:430 Promise.then (async) (anonymous) @ script.js:154

Mac - 10.15.2 Chrome - 79.0.3945.117

According to this link - https://www.midi.org/17-the-mma/99-web-midi , Chrome definitely has the support.

Important Note - If I were run the code directly on codepen, it works just fine. So the browser is working. But when I try to run locally, I get the error.

I've used web-midi with Chromium and Opera on 10.12.6, so I wouldn't say that Chrome is the only browser that has web-midi.

With Opera I think I had to enable experimental features:
