roadmap question: rtype builtins

I was thinking about taking a crack at this, but I’m not sure I understand what this bullet point is, exactly.

I assume this is pre-parser, and is for building predicates in JavaScript.

e.g.

import  { isAny, isArray, isBoolean, isFunction, isNumber, isObject, isString, isVoid } from 'rfx-builtins';
import  rfx from 'rfx';

const type = (param, otherParam, options) => (
  isString(param) &&
  isArray(otherParam) &&
  /* ... (Type checking optional and neatly separated!) */
);

export const myFunction = (param, otherParam, options) => {
  /* (Just business logic.) */
}

export const myInterface = rfx({
  type,
  fn: myFunction
});

Is this pretty much what you were expecting? The exported predicate names can’t literally be the same as the built-in names, so I just went with a conventional (to me) is... prefix.

Also, have you seen this type checking library? https://github.com/enricomarino/is Would it be appropriate to just extract the builtin-related functions from that (it’s also MIT licensed)?

Anyway, 👍 to not supporting IE <11. How about mentioninig it in the docs?

Closing because type check implementations are out of scope for rfx.

rfx is just a way to tag interfaces with type information. See rtype for actual type checking code.
