Preact offers, in addition to the regular component API from React, the ability to access both props & state as function parameters to the render method. This lesson will cover an example of how to utilize this convenience along with how destructuring can make it even nicer to work with.
import {h, Component} from 'preact';
import User from './User';
export default class App extends Component {
constructor(props) {
super(props);
this.state = {
loading: true,
user: null
};
}
componentDidMount() {
fetch(this.props.config.urls.user)
.then(resp => resp.json())
.then(user => {
this.setState({
user,
loading: false
});
})
.catch(err => console.error(err));
}
// render(props, state) {
render({config}, {loading, user}) {
return (
<div class="app">
{loading
? <p>Fetching {config.urls.user}</p>
: <User image={user.avatar_url}
name={user.name} />
}
</div>
);
}
}
