What’s New in ExtReact 6.6.1

Support for React 16.5

ExtReact 6.6.1 supports React 16.5 with support for React dev tools profiler, updates to React DOM events, new scheduler and a number of bug fixes.

React’s virtual dom is known for efficiently rendering components and you can track the performance of the React apps with new React code and Chrome DevTools. You can use them to diagnose slow rendering parts of your application. In the development mode, you can visualize how components mount, update, and unmount, using the performance tools in supported browsers.

Support for Babel 7

ExtReact 6.6.1 supports Babel 7. Babel is a transpiler for JavaScript that is popular among developers for its ability to turn ES6 or ES7 into code that can run on your browsers and devices. Babel 7 is faster and comes with an upgrade tool, JavaScript configurations, configuration overrides, options for size minification, support for React’s JSX Fragments, and support for TypeScript. Update your ExtReact application with dependencies as below:

“dependencies”: {

“@sencha/ext-react”: “~6.6.1”,

“devDependencies”: {

“@babel/core”: “^7.0.0”,
“@sencha/ext-react-babel-plugin”: “~6.6.1”,
