Description

Replaces usages of componentWillUpdate with UNSAFE_componentWillUpdate.

This API has been renamed from componentWillUpdate to UNSAFE_componentWillUpdate. The old name has been deprecated. In a future major version of React, only the new name will work.

Examples

Before

import React from "react";
 
class MyComponent extends React.Component {
  componentWillUpdate() {
    // ...
  }
}

After

import React from "react";
 
class MyComponent extends React.Component {
  UNSAFE_componentWillUpdate() {
    // ...
  }
}
