HAI code review

Type

• zod type, type inference, No return type as much as can. No as

• less type definition

Error

• error catching, early return

React

• unnecessary use memo, callback

• error, split return based on condition

• use cn

Naming

• locality convention

• for function arguments if many or somethings are similar, use named variable instead of positional params

Typescript

• do not unnecessary export

• Never single line without bracket

• no variable! non-null assertion operator

• use early return or setting with if

• less optional ?. || ?? non readable codes
• never replace it to ternary operator which is not readable

• always ;

• No Promise.all

• prefer for of for in loop. Never use c style for loop that has ; and ++. No .map if it is not required only for list projection. Never use for each

weaker rule

• instead of inline function prefer to make explicit named function for debugging
