Package Exports

tree-changes-hook

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tree-changes-hook) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

tree-changes-hook

React hook that uses tree-changes to compare changes between two datasets.

Setup

npm install tree-changes-hook

Usage

import React from 'react';
import useTreeChanges from 'tree-changes-hook';

function App(props) {
  const { changed } = useTreeChanges(props);

  React.useEffect(() => {
    if (changed('hasData', true)) {
        sendAnalyticsEvent('load', 'MySuperPage');
      }
  });

  return <div>...</div>;
}

It's safe to run all the methods with a useEffect without dependencies but it works with them too.

API

Please refer to tree-changes README for detailed usage.
