Actually to use ES6 modules, a server needs to be running . Otherwise we get CORS errors.
My question here, can we inject scripts which load other modules (<script src="abc.js" type="module> ") into QWebEnginePage without running any server??

Can I import other scripts in my .js files like @Import "abc" "abc.js"

Does QWebEnginePage start any server in the background?

INFO: In case of electron, node js manages 'require' statements without starting any server.
