Discussion: propTypes.string.isNotEmpty

[billfienberg]

I was recently working on a component that had a button, and I wanted to make sure that consumers of the component passed a string for the button's aria-label. I am currently using propTypes.string.isRequired, but that is satisfied with an empty string (''). I checked the prop-types documentation, and was disappointed there was no propTypes.string.isNotEmpty.

I realize that an empty string is still a string, and that checking the value of the string is more validation than type-checking. I also realize that it is not difficult to write a custom propType, and that there are 3rd-party propType packages available.

Has this specific topic (propTypes.string.isNotEmpty) ever been publicly discussed as a candidate for prop-types? If so, will you please refer me to any documentation from those previous discussions?
