I use componentWillReceiveProps for just about everything - I had thought it was a fundamental part of the Redux flow. i.e. Redux updates, new props flow through the hierarchy, I pick that up in componentWillReceiveProps and make changes based on new props.
Is this not correct?
- spicyj 9y agoLet's keep the discussion on that thread – I just responded there.
- brianvaughn 9y agoThe purpose of componentWillReceiveProps was to update state in response to props changes. (This is also the purpose of getDerivedStateFromProps.) What you're describing sounds more like you're updating something external (e.g. your Redux store). This isn't what the lifecycle is meant for, and you'd be better off using componentDidUpdate instead.
