react native component did update code example
Example 1: prev props
componentDidUpdate(prevProps) {
// Utilisation classique (pensez bien à comparer les props) :
if (this.props.userID !== prevProps.userID) {
this.fetchData(this.props.userID);
}
}
Example 2: shouldcomponentupdate
shouldComponentUpdate(nextProps, nextState) {
return true;
}
Example 3: react lifecycle
constructor(props) {
super(props);
// Don't call this.setState() here!
this.state = { counter: 0 };
this.handleClick = this.handleClick.bind(this);
}
