Extended Prop Types

Useful proptypes for React components. Developed for and tested on ClassDojo's web app.

Usage

Individual validators can be imported under /validators.

import keyedObject from "extended-proptypes/validators/keyedObject";

class MyComponent extends Component {

  static propTypes = {
    mySpecialObject: keyedObject(/keyregex/).isRequired,
  };
}

You can also import the whole module and call it on React.PropTypes, extending React's PropTypes with all included validators.

import {PropTypes} from "react";
import ExtendedPropTypes from "extended-proptypes";

// New options will now be available on React's `PropTypes` export.
ExtendedPropTypes(PropTypes);

class MyComponent extends Component {

  static propTypes = {
    myDate: PropTypes.date,
    mySatanicString: PropTypes.stringMatching(/^6+$/).isRequired,
    myArrayOrObject: PropTypes.collectionOf(PropTypes.bool),
  };
}

Finally, all validators are properties of the module.

import ExtendedPropTypes from "extended-proptypes";

class MyComponent extends Component {

  static propTypes = {
    myEmailAddress: ExtendedPropTypes.emailAddress.isRequired,
  };
}

• collectionOf(validator): An array or a plain object whose values match the provided validator.
• keyedObject(regex): An object whose keys match the provided regex.
• keyedObjectOf(regex, validator): An object whose keys match the provided regex and whose values match the provided validator.
• iterable: An iterable. Errors if enviroment does not support symbols.

General Primatives

• constant(val): The provided val, only.
• primative: a number, a string, or a boolean.
• stringMatching(regex): A string that matches the provided regex.

• date: A date object.
