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`.'
})
