What strategies are most effective in managing unexpected drag and drop events while working on a project?

Can you forgive my quirky question? I'm facing a problem with drag/drop events while working on an Electron project.

The issue goes like this:

  • During development (using Vue / Electron-builder, etc.), I run in "electron-builder:serve" mode. This mode respawns the application browser window whenever I make code changes. It's helpful because it saves time and prevents the compiler from re-compiling all my JavaScript for small changes.
  • However, it seems that there is a lingering DOM instance, causing double triggering of events when I try to "drop" a file onto my application window. The number of events triggered equals the number of times the application window has respawned.
  • This annoyance leads me to shut down the dev server and restart it so that only one event is handled.

I hope I've explained the problem clearly. There's no code involved; just a query about the setup. Ideally, I would like the application to handle a single drop event every time I respawn during development.

This doesn't seem like a production issue but rather a troublesome aspect of development.

Answer №1

I encountered a similar issue where keydown events were being duplicated in server mode. I was able to resolve this by utilizing lifecycle hooks:

For Vue 2:

mounted() {
    window.addEventListener('keydown', this.onKeyDown);
},
destroyed() { // or potentially beforeDestroy
    window.removeEventListener('keydown', this.onKeyDown);
}

For Vue 3 Composition API:

onMounted((): void => {
    window.addEventListener('keydown', onKeyDown);
});
onBeforeUnmount((): void => {
    window.removeEventListener('keydown', onKeyDown);
});

This solution may also be applicable to your code.
