@raclim You missed some:
https://github.com/processing/p5.js-web-editor/blob/develop/client/modules/Preview/filesReducer.js
https://github.com/processing/p5.js-web-editor/blob/develop/server/scripts/examples-gg-latest.js

IMO it's crazy that we have the same constants in so many files. It makes this sort of maintenance a nightmare. I'd like to put in a PR to export/import this from some central location.

Thanks for pointing this out! These files were probably missed during the last few updates as well.

Agreed, I think narrowing the changes to one variable or location would be a great!
