Returns:

true to enable human readable names for components.

shouldMinimizePropKeys

@JsOverlay
public static boolean shouldMinimizePropKeys()

Return true if the prop keys should be minimized. This will significantly reduce the size of the compiled output but will make inspecting the props in DevTools difficult if not impossible.

Returns:

true to minimize prop keys.

shouldValidatePropValues

@JsOverlay
public static boolean shouldValidatePropValues()

Return true if the prop value should be validated when initially set or when changed.

Returns:

true to validate prop values.

shouldStoreDebugDataAsState

@JsOverlay
public static boolean shouldStoreDebugDataAsState()

Returns:

true if react state should be used to store debug data.

shouldCheckInvariants

@JsOverlay
public static boolean shouldCheckInvariants()

Return true if invariants will be checked.

Returns:

true if invariants will be checked.

shouldFreezeProps

@JsOverlay
public static boolean shouldFreezeProps()
