Build a Yup schema from a JSON Schema. Also supports custom/alternative schema models such as GraphQL type defs

import { Constraint } from './base';

function createRegExpConstraint(typer, map) {
  return new RegExpConstraint(typer, map);
}

  }

  }

    return new RegExp(value);
  }

  isRegExpLike(value) {
    return value instanceof RegExp || this.isStringType(value);
  }

  get explainConstraintValidMsg() {
    return `Must be either a RegExp or String`;
  }
}

export {
