Introduction

Fluent prop validation for Vue that won't land in your production code.

It uses process.env.NODE_ENV !== 'production' to detect production build. Use rollup-plugin-replace for rollup and DefinePlugin for webpack.

Usage

Installation

npm install --save @znck/prop-types

Examples

import PropTypes from '@znck/prop-types'; // ES6
var PropTypes = require('@znck/prop-types'); // ES5 with npm

// babel.config.js or .babelrc.js
...
  plugins: [
    '@znck/prop-types/replace'
  ]
...

Here is an example of using PropTypes with a Vue component, which also documents the different validators provided:

<script>
import PropTypes from 'prop-types';

export default {
  props: {
    // You can declare that a prop is a specific JS primitive. By default, these
    // are all optional.
    optionalArray: PropTypes.array,
    optionalBool: PropTypes.bool,
    optionalFunc: PropTypes.func,
    optionalNumber: PropTypes.number,
    optionalObject: PropTypes.object,
    optionalString: PropTypes.string,
    optionalSymbol: PropTypes.symbol,

    // You can also declare that a prop is an instance of a class. This uses
    // JS's instanceof operator.
    optionalMessage: PropTypes.instanceOf(Message),

    // You can ensure that your prop is limited to specific values by treating
    // it as an enum.
    optionalEnum: PropTypes.oneOf(['News', 'Photos']),

    // An object that could be one of many types
    optionalUnion: PropTypes.oneOfType([
      PropTypes.string,
      PropTypes.number,
      PropTypes.instanceOf(Message)
    ]),

    // An array of a certain type
    optionalArrayOf: PropTypes.arrayOf(PropTypes.number),

    // An object with property values of a certain type
    optionalObjectOf: PropTypes.objectOf(PropTypes.number),

    // An object taking on a particular shape
    optionalObjectWithShape: PropTypes.shape({
      color: PropTypes.string,
      fontSize: PropTypes.number
    }),

    // You can chain any of the above with `isRequired` to make sure a warning
    // is shown if the prop isn't provided.
    requiredFunc: PropTypes.func.isRequired,

    // A value of any data type
    requiredAny: PropTypes.any.isRequired,

    // You can also supply a custom validator.
    customArrayProp: PropTypes.string.validate(value => value === 'foo'),
  }
}
</script>
