Move data fetching code or side effects to componentDidUpdate.

itrevex commented 4 years ago

Rename componentWillUpdate to UNSAFEcomponentWillUpdate 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.

Issue poping all the time that may need fixing
