react/no-misspelled-lifecycle-methods

Reports unambiguous spelling or casing mistakes in React class lifecycle methods, and whether the method is declared with the required staticness. It is enabled in recommended.

The rule recognizes a class only when its superclass is a statically proven import from react (Component or PureComponent). A class that merely uses the name React is not enough.

Incorrect

import React from 'react';

class Profile extends React.Component {
  componentDidMout() {}

  static componentDidMount() {}
}

Correct

import { Component } from 'react';

class Profile extends Component {
  componentDidMount() {}

  static getDerivedStateFromProps(props, state) {
    return state;
  }
}

This is a narrow rule for React class lifecycles. It does not inspect function components, object literals, custom base classes, or arbitrary identifiers.
