How can i declarate componentDidMount without creating class extends react component? For example render() declarates with react-dom package, maybe is exist another package for componentDidMount?
class App extends Component {
constructor(){
// do something
}
componentDidMount(){
// js code must run after page loaded
}
render(){
return(
<div className="app">
</div>
);
}
}
export {App};
The same thing with component constructor()
const App = () => {
// constructor and componentDidMount does not work here
// js code must run after page loaded
return (
<div className="app">
</div>
);
};
export {App};
First of all, what you want to achieve is fully Meteor independent. It's a pure React problem that could exist with any backend. What you want to achieve can be done using the useEffect() hook for which you'll find the documentation right here:
https://reactjs.org/docs/hooks-reference.html#useeffect
Here is a great article explaining how to replace lifecycle methods with hooks:
https://dev.to/trentyang/replace-lifecycle-with-hooks-in-react-3d4n
In your case, for componentDidMount you'll have to do the following:
useEffect(() => {
// js code must run after page loaded
}, []);
In the final array you have to put dependency that will retrigger the hook if you need. To imitate a simple componentDidMount an empty array is generally the solution.
