Validating Props
In this example, we are creating App component with all the props that we need. App.propTypes is used for props validation. If some of the props aren't using the correct type that we assigned, we will get a console warning. After we specify validation patterns, we will set App.defaultProps.
App.jsx
import React from 'react'; class App extends React.Component { render() { return ( <div> <h3>Array: {this.props.propArray}</h3> <h3>Bool: {this.props.propBool ? "True..." : "False..."}</h3> <h3>Func: {this.props.propFunc(3)}</h3> <h3>Number: {this.props.propNumber}</h3> <h3>String: {this.props.propString}</h3> <h3>Object: {this.props.propObject.objectName1}</h3> <h3>Object: {this.props.propObject.objectName2}</h3> <h3>Object: {this.props.propObject.objectName3}</h3> </div> ); } } App.propTypes = { propArray: React.PropTypes.array.isRequired, propBool: React.PropTypes.bool.isRequired, propFunc: React.PropTypes.func, propNumber: React.PropTypes.number, propString: React.PropTypes.string, propObject: React.PropTypes.object } App.defaultProps = { propArray: [1,2,3,4,5], propBool: true, propFunc: function(e){return e}, propNumber: 1, propString: "String value...", propObject: { objectName1:"objectValue1", objectName2: "objectValue2", objectName3: "objectValue3" } } export default App; |
