Package Exports

proptypes

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (proptypes) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

proptypes

React's PropTypes, packaged up as a standalone module.

DISCLAIMER: This is literally copied from the React 0.14 codebase. If you're using PropTypes with React, it would be silly to reference this standalone version.

Usage

function check(props, propTypes) {
  for (let prop in propTypes) {
    if (propTypes.hasOwnProperty(prop)) {
      let err = propTypes[prop](props, prop, 'name', 'prop');
      if (err) {
        console.warn(err);
        return false;
      }
    }
  }
  return true;
}

let valid = check({
  a: 42,
  b: 'News'
}, {
  a: PropTypes.number,
  b: PropTypes.oneOf(['News', 'Photos'])
});

valid;  // true

Production build

Disabling

With webpack:

module.exports = {
  resolve: {
    alias: {
      proptypes: 'proptypes/disabled',
    }
  }
};

Removing the definitions with React

When you are using this package with React like API, you might want to save bandwidth by removing the definitions. You can use babel-plugin-transform-react-remove-prop-types for that use case, for instance:

// In
const Baz = (props) => (
  <div {...props} />
);

Baz.propTypes = {
  className: PropTypes.string
};

// Out
const Baz = (props) => (
  <div {...props} />
);
