Error handling patterns


In some implementations where I draw a form for example on a page, I place a conditional on that form preventing it from being drawn if error specific prerequisites have not been meet. For example, in the try/catch block of ajax calls used to populate multi selects, I toggle a boolean if an exception occured.

I want to combine several shared multi selects into child components, how can I use Vue’s error handler to terminate the rendering, or should I use it to simply invert the original conditional to prevent offering a broken form?
