What is airbnb-prop-types?
The airbnb-prop-types package provides a collection of React propType validators that can be used to ensure that components receive props of the correct type, shape, and value. It extends the basic propTypes provided by React with more specific and useful validators, making it easier to catch bugs and enforce consistent prop usage across a codebase.
What are airbnb-prop-types's main functionalities?
Primitive Type Validators
Allows for more specific type validation, such as ensuring a prop is a non-empty string.
import { string } from 'airbnb-prop-types';
Component.propTypes = {
name: string().isRequired,
};
Collection Validators
Enables validation of arrays, ensuring each item in the array matches the specified validator.
import { arrayOf } from 'airbnb-prop-types';
Component.propTypes = {
items: arrayOf(string()).isRequired,
};
Shape Validators
Allows for the validation of an object's shape, ensuring it matches a specific schema.
import { shape } from 'airbnb-prop-types';
Component.propTypes = {
user: shape({
id: number().isRequired,
name: string().isRequired,
}).isRequired,
};
Custom Validators
Provides the ability to create custom validators, such as forbidding extra props that are not explicitly specified.
import { forbidExtraProps } from 'airbnb-prop-types';
Component.propTypes = forbidExtraProps({
name: string().isRequired,
age: number(),
});
Other packages similar to airbnb-prop-types
prop-types
The original prop-types library used for React prop type validation. It offers basic type checking but lacks the more specific validators and features provided by airbnb-prop-types.
react-immutable-proptypes
A library offering propType validators specifically designed for Immutable.js data structures. While it serves a niche use case compared to airbnb-prop-types, it's invaluable for projects using Immutable.js.
yup
Yup is a JavaScript schema builder for value parsing and validation. Unlike airbnb-prop-types, which integrates directly with React prop types, Yup is more versatile and can be used outside of React for form validation and more.
