I have an app using React and Express so, following the advice of multiple different blog posts around the web, I’ve put the React stuff into its own subdirectory and given it its own package.json, where I add the following line:
(3001 being the port Express is listening on.)
With that line in there, instead of my app, I see a blank page except for the text “Invalid Host header”. I’m guessing that this is because the generic advice I’ve found online doesn’t work for the way Glitch projects are set up. Anyone know what I can change so my React code can access endpoints on my Express server?
