Throw error when props validation fails

[yazfield]

What problem does this feature solve?

Currently props validation only issues a warning in non production environment.

I was trying to create a component like react's error-boundary to handle invalid props and show fallback componentsusing errorCaptured but it is unfortunately not possible.

What does the proposed API look like?

something like a callback to be called when validating props

Vue.config.assertPropsHandler: Function;

prop validation is intentionally dev only to keep it out of production bundle. You can add a custom handling for errors to handle this: https://jsfiddle.net/7pawb8ou/. Note you could also throw the error during render if you use a wrapper component, allowing you to catch it in errorCaptured
