issue (complexity): Consider extracting inline callbacks and nested logic into smaller helper functions to improve code organization and readability.
Extract inline callbacks and nested logic into smaller helper functions. For example, instead of writing the callbacks directly in the constructor of the drag-and-drop observer, extract the event handlers:
// Define helper to create drag-and-drop handlers
function createDragAndDropHandlers(referenceContainer) {
return {
onDragEnd: (e) => referenceContainer.dropTarget.dnd.onDragEnd(e),
onDragEnter: (e) => referenceContainer.dropTarget.dnd.onDragEnter(e),
onDragLeave: (e) => referenceContainer.dropTarget.dnd.onDragLeave(e),
onDrop: (e) => referenceContainer.dropTarget.dnd.onDrop(e),
onDragOver: (e) => referenceContainer.dropTarget.dnd.onDragOver(e)
};
}Then use it in your code:
const disposable = new CompositeDisposable(
observerDisposable,
new DragAndDropObserver(focusContainer, createDragAndDropHandlers(referenceContainer)),
panel.api.onDidVisibilityChange(() => visibilityChanged()),
panel.api.onDidDimensionsChange(() => {
if (panel.api.isVisible) { resize(); }
}),
panel.api.onDidLocationChange(() => correctLayerPosition())
);Similarly, for complex promise chains (for the popout window code), refactor nested logic into self-contained functions that handle specific responsibilities. For instance, you might extract the popout creation logic:
function handlePopoutWindow(_window, overlayRenderContainer, referenceGroup, options) {
const popoutContainer = _window.window.document.body; // or however you get it
// ... extracted and simplified initialization
popoutContainer.classList.add('dv-dockview');
popoutContainer.style.overflow = 'hidden';
// Append and configure DOM elements
return popoutContainer;
}
// Then call:
_window.open().then((popoutContainer) => {
if (_window.isDisposed || popoutContainer === null) {
// error handling
return false;
}
const container = handlePopoutWindow(_window, overlayRenderContainer, referenceGroup, options);
// rest of the logic...
});These steps help separate concerns and flatten deeply nested inline logic, making the code easier to read and maintain while preserving all functionality.

issue (code-quality): Use const or let instead of var. (avoid-using-var)
Explanation
`const` is preferred as it ensures you cannot reassign references (which can lead to buggy and confusing code). `let` may be used if you need to reassign references - it's preferred to `var` because it is block- rather than function-scoped.From the Airbnb JavaScript Style Guide
