Hi! Does somebody knows if there's possible to have React and Express in completely different folders? Lets say like this: - Project ---Frontend ---Backend And there's no package.json inside of project, just each folder has it's own package.json. What I want to know is if I can put concurently inside Backend code, then tell it to go an upper level, and then go inside Frontend folder to execute react commands?
