So, I am trying to do a GET fetch request, client-sided even though I should do it server-side, because of CORS, but I don't know yet how to do that. Anyway, the request was made to https://www.youtube.com/watch?v=blablabla but it seems that now, the page on which the request was made is rendering the HTML output of the YouTube video. I tried everything : - commenting out the request call - clearing Firefox' cache - opening the page on private tab - reloading the Vinxi dev server - removing node_modules and re-installing them Nothing worked so far, what ever I do, I still have the Youtube page rendering on my application... I don't know what to do to get back to the normal behaviour. Is there another kind of cache that I am missing ? If so, I really thought it would be gone when removing node_modules and clearing browser's cache... Any thought ?
