    Validate Prop Types

    This package is a modified version of PropTypes.checkPropTypes(), the difference being that it returns errors as an object instead of issuing a console.error.

    ExampleComponent.js

    const PropTypes = require('prop-types')
    const ExampleComponent = () => 'hello'
     
    ExampleComponent.propTypes = {
      a: PropTypes.string.isRequired,
      b: PropTypes.number,
      c: PropTypes.object
    }

    ExampleComponent.test.js

    const assert = require('assert')
    const validatePropTypes = require('validate-prop-types')
    const ExampleComponent = require('./ExampleComponent')
     
    const data = {
      b: 'a string',
      c: 'another string'
    }
     
    assert.deepEqual(validatePropTypes(ExampleComponent.propTypes, data), {
      a: 'The prop `a` is marked as required in `Component`, but its value is `undefined`.',
      b: 'Invalid prop `b` of type `string` supplied to `Component`, expected `number`.',
      c: 'Invalid prop `c` of type `string` supplied to `Component`, expected `object`.'
    })
