prop-types-helper

Tired of writing propTypes on your React App? Try using propTypesHelper. it provides proptypes from the default values in the object.

some examples

import * as helper from 'proptypes-helper';
 
const types = {
  optional: {
    Array: [],
    Bool: true,
    Func: ()=>{},
    Number: 1,
    Object: {},
    String: '',
    Symbol: Symbol('desc'),
    Element: <div />
  },
  required: {
    Array2: [ 1 ],
    Number2: NaN,
  },
  external: {
    Instance: PropTypes.instanceOf(Message)
  }
}
 
function StatelessButton(props) {
...
}
StatelessButton.defaultProps = { ...helpers.defaultProps(types) };
StatelessButton.propTypes = { ...helpers.propTypes(types) };
// or
StatelessButton = helpers.attachTypes(StatelessButton, types);
 
class Button extends Compoment {
  static defaultProps = { ...helpers.defaultProps(types) }
  static propTypes = { ...helpers.propTypes(types) }
 
...
 
}

** if your linter barks at proptypes, try use spread ({...xxx}). It should be the same as StatelessButton.propTypes = helpers.propTypes(types);.

You can also easily toggle between optional and required since it use the same form.

when you want to see what are genereated

only in dev env, setDebug(true) will show console.log for keys and propTyes

coverage

setDebug will show the followings for the upper example

• Array: PropTypes.array
• Bool: PropTypes.bool
• Func: PropTypes.func
• Number: PropTypes.number
• Object: PropTypes.shape()
• String: PropTypes.string
• Symbol: PropTypes.symbol
• Element: PropTypes.element
• Array2: PropTypes.arrayOf(PropTypes.number).isRequired
• Number2: PropTypes.number.isRequired

If one of those is needed

• any
• customProp
• oneOf
• oneOfType
• node
• objectOf
• instanceOf
• object ; generated as shape
• array ; generated only for empyt array.

or precise proptypes, please write that in the external parameter.
