Called twice with react strict mode

[shadowvzs]

Hi, in strict mode it is called twice, which is an issue if we have an api call method or class instantiation

This is how React works - you can't instantiate anything that has side-effects with useConstant. Side effects belong to useEffect/event handlers (or to outside of your components)

@Andarist I thought it should be used for instantiating a store class too with useConstant but this isn't the case, useEffect is called after the component was mounted and not parallel

Yes, but again - this is how React works. useConstant is resolved in render, and render should always be pure.
