[RFC] Content Script UI on click with activeTab permission only

[jeroenbernaerts]

How do you envision this feature/change to look/work like?

Instead of providing match URLs in PlasmoCSConfig, allow a UI (ex. react component) to be mounted when the extension icon is clicked, on thus activeTab permission is acquired; https://developer.chrome.com/docs/extensions/get-started/tutorial/scripts-activetab#active-tab

What is the purpose of this change/feature? Why?

By using the URL match approach, a warning is triggered when installing the extension (see example). It is encouraged to use activeTab permissions. The content script will always be injected on the matching URLs, some extensions might only need to inject scripts on (extension icon) click action.

(OPTIONAL) Example implementations

Option to leave matches key empty in CS(UI) (or not use PlasmoCSConfig at all)

export const config: PlasmoCSConfig = {
  matches: []
};

Trigger the UI injection from background service worker

chrome.action.onClicked.addListener(async (tab) => {
    // Any code before injection (check URL, ...)
    // Invoke UI injection of some Plasmo CSUI
}
