cloning a plasmo repo and running it on a different device
Hello! really stupid question but how do i go about cloning my plasmo project onto a diff device?
i cloned it on my desktop, which is setup with node and everything, but i can't just npm i and go. is there some sort of npx command or something i need to run before hand? i tried running npx plasmo init but that didn't seem to work (same result as npm i) so I'm not sure what the reproduction steps are...

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?...

Scrape many pages with plasmo
Hello, i’m new to the framework and I feel a little bit overwhelmed. So I decided to ask the Plasmo people directly.
So my need is to scrape a few pages as the browser owner, extract a JSON and provide it as a download. Since the website is blocked by authentication shenanigans and that my use case rely on authenticated users to extract the data i’ve opted to run a web extension.
I’ve been able to use the
PlasmoCSConfig and PlasmoGetInlineAnchor to add a button on the website. That’s great. I’ve also been able to change the current url, upon click event. I’ve also read and explored a little bit around WORLD script injection....Mount UI content script on extension click
I feel incredibly silly not being able to work this out without weird workarounds, but what is the "native" way to inject ui into the main world / page you are seeing in Plasmo?
I'm new to the chrome extension game, and i could get a background script to inject ui on click, but i cant seem to figure out how to inject the ui on extension click with using the whole mount react component thing with anchors etc.
Any resources beyond just the docs.plasmo on how to mount the components?...
