First dev command results in an error

I just wanted to make myself a small demo of Plasmo, but I got this error when trying to run the command. Can it be because of some specific version requirements?...

Keeping Chrome dev tools open during development.

Hey guys, I built my Chrome extension a couple of years ago without Plasmo - and one of the biggest pains in the a** during development was having to constantly re-open Chrome's dev tools every time the extension was closed or reloaded. Is this something Plasmo can help with?

Is Svelte 5 supported?

I'm trying to use svelte 5 with plasmo but keep getting the error "No supported UI library found". I created the project using the svelte 4 template (plasmo init --with-svelte) and then modified the package.json and svelte config file to use the newer svelte 5. But didn't manage to make it work. Does plasmo not support Svelte 5 yet?...

Best way to send a message from popup to content and get a response in Plasmo?

Hi everyone, I'm working on a Plasmo extension and trying to send a message from the popup to the content script and receive a response back in the popup. I read that one approach is to use storage as an intermediary—where the content script updates the storage and the popup listens for changes. However, since storage has limitations, I'd like to explore other options. Would chrome.runtime.sendMessage or chrome.tabs.sendMessage be a better approach for direct communication? Or is there another recommended method in Plasmo for handling this?...
