Code
For both frontend/backend:
- keep code stupid (debugging is twice as hard as coding)
- names should be describing well what they are for and adhere to our glossary
- avoid magic constants, prefer to use constant variables instead
- avoid obviously inefficient code if more efficient solutions are available (please benchmark or ask in case of doubt)
- Make sure the correct encoding (UTF-8) and line break type (LF) is used. This is probably not an issue when working with Linux but in Windows the defaults seem to be UTF-16 and CRLF so be aware when using different operating systems.
For frontend:
- don't overuse useEffect (see You Might Not Need an Effect)
