require-react-display-names

Requires displayName on exported memoized components and exported contexts.

Rule details Problem

The rule tracks calls to memo(...) and createContext(...) from the configured React environment.

It reports two cases:

• direct default exports such as export default memo(Component) or export default createContext(...)
• exported variables created from memo(...) or createContext(...) that never get a .displayName assignment

By default, environment is "roblox-ts". Switch to "standard" to use regular React package sources.

What counts as a display name assignment

The rule looks for SomeValue.displayName = .... It does not require the string to match the variable name, but that is the intended pattern.

Examples

Incorrect

export default memo(ButtonImpl);

export const UserContext = createContext(undefined);

Correct

const Button = memo(ButtonImpl);
Button.displayName = "Button";
export default Button;

const UserContext = createContext(undefined);
UserContext.displayName = "UserContext";
export { UserContext };

Options

Option	Type	Default
environment	"roblox-ts" | "standard"	"roblox-ts"
