NGXLaunchpad

A small library for angular 8 to communicate with a Novation Launchpad.

This library uses the Launchpad WebMIDI library. Shoutout to LostInBrittany for his really nice work! Without his work, my work would be even harder ;) Don't forget to give him a star ♥.

Installation

• Install via npm:

npm install --save ngx-launchpad

Usage

Implement the NgxLaunchpadModule into your module like this:

import {NgxLaunchpadModule} from '../../../ngx-launchpad/src/lib/ngx-launchpad.module';

@NgModule({
  declarations: [MyComponent],
  imports: [
    BrowserModule,
    NgxLaunchpadModule // <-- include it in your app module
  ],
  bootstrap: [MyComponent]
})

and then, you can import the NgxLaunchpadService into every component like this:

constructor(private launchpadService: NgxLaunchpadService) {
}
