PropTypes for Preact

See original GitHub issue

Hi. I’ve realised PropTypes’s alike extensible type checker which produce nice-looking report object. Instead of PropTypes which print’s some output into console. And I want to add integration for preact. Is there any way to make it play together without patching preact itself?

It could be used like so:

const TypedProps = require('typed-props');

const userShape = TypedProps.shape({
    username: TypedProps.string.isRequired,
    age: TypedProps.number,
});

TypedProps.check({}, userShape); // -> returns array of issues: {path:string[], rule:string, params:{}}

Thanks for any advise.

P.S. Here it is.

Just an FYI: PropType checking will be possible in Preact X itself. That means that compat won’t be needed just for PropTypes anymore. Merged the PR for it yesterday 🎉

You can copy what we do there though, only enable it in dev, the check gets removed in a production build because of dead code elimination
