babel-plugin-flow-onlyupdateforkeys

A babel plugin to generate args of recompose.onlyUpdateForKeys from flow type. It is intended to be an alternative to recompose.onlyUpdateForPropTypes for flow type.

Example

In

// @flow
import React from 'react';
import { compose, onlyUpdateForKeys } from 'recompose';

export default compose(
  onlyUpdateForKeys(), // without args
)(function Foo(props: { foo: string, bar: number }) {
  const { foo, bar } = props;

  return (
    <div>{foo}-{bar}</div>
  );
});

Out

// @flow
import React from 'react';
import { compose, onlyUpdateForKeys } from 'recompose';

export default compose(
  onlyUpdateForKeys(['foo', 'bar']), // with args
)(function Foo(props: { foo: string, bar: number }) {
  const { foo, bar } = props;

  return (
    <div>{foo}-{bar}</div>
  );
});
