I’ve downloaded the category badge component, made some changes, zipped it (right click > compress on Mac) and then when I try to Install > from your device it tells me: An error occurred: Import Error: about.json does not exist, or is invalid. Are you sure this is a Discourse Theme? Even if I just…

I recommend that you Install the Discourse Theme CLI console app to help you build themes .

Using that creates a skeleton but has other issues: it’s 24MB compressed (so too big, discourse won’t accept it - node_modules alone is 119MB). I just want to make a quick edit to this theme - can’t I just download, make a change then upload it as a new component with the ‘from my device’ option?

Don’t create a zip file. Use the cli to push the edited theme back up. It’s what it’s for and makes it very easy to edit and see what you’re changes do.

An alternative you could explore is to create a new component with Overrides you want.

Le composant téléchargé s'installe bien, mais pas une fois modifié/recompressé.

Je vous recommande d’installer l’application de console Discourse Theme CLI pour vous aider à créer des thèmes.
