To create a basic widget, simply create a code note with type “JS frontend”. Add the #widget label in order for it to be loaded at startup.
const template = `<div id="my-widget"><button>Click Me!</button></div>`;
class MyWidget extends api.BasicWidget {
    get position() { return 1; }
    get parentWidget() { return "left-pane" }
    
    doRender() {
        this.$widget = $(template);
        return this.$widget;
    }
}
module.exports = new MyWidget();parentWidget() can be given the following values:
- left-pane- This renders the widget on the left side of the screen where the note tree lives.
- center-pane- This renders the widget in the center of the layout in the same location that notes and splits appear.
- note-detail-pane- This renders the widget with the note in the center pane. This means it can appear multiple times with splits.
- right-pane- This renders the widget to the right of any opened notes.
