Warning: componentWillReceiveProps has been renamed, and is not recommended for use.

Hello!
My browser keeps yelling this warning.

´´´
Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See https://fb.me/react-async-component-lifecycle-hooks for details.

• Move data fetching code or side effects to componentDidUpdate.
• If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at: https://fb.me/react-derived-state
• Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE_ name will work. To rename all deprecated lifecycles to their new names, you can run npx react-codemod rename-unsafe-lifecycles in your project source folder.

Please update the following components: ReflexElement

Can I help you update this or are you already working on it?

Yeah, haven't got time to migrate so far... All I did is a place older.

Feel free to contribute if you want to implement getDerivedStateFromProps.

Thanks

Okidoki,
I'll try to do that!

I forked and did some changes but, I really don't know how to use your Demo 😋
How to start a server after running npm run build-demo-dev ? (sry for my noobish questions)

[leefsmp]

just open index.html in the browser, no need a server but you could use any local http server of your choice if you prefer.

Closing that for now as using UNSAFE_componentWillReceiveProps should suppress the warning. Migrating ReflexContainer to use getDerivedStateFromProps is a lot of internal changes so postponing it until it becomes a real problem. ReflexElement has now been migrated in v 3.0.18.
