React Props in React Default props
Example
defaultProps allows you to set default, or fallback, values for your component props. defaultProps are useful when you call components from different views with fixed props, but in some views you need to pass different value.
Syntax
ES5
var MyClass = React.createClass({
getDefaultProps: function() {
return {
randomObject: {},
...
};
}
}
ES6
class MyClass extends React.Component {...}
MyClass.defaultProps = {
randomObject: {},
...
}
ES7
class MyClass extends React.Component {
static defaultProps = {
randomObject: {},
...
};
}
The result of getDefaultProps() or defaultProps will be cached and used to ensure that this.props.randomObject will have a value if it was not specified by the parent component.
