You can install react-async from npm:

npm install --save react-async

Or if you're using Yarn:

yarn add react-async

This package requires react as a peer dependency. Please make sure to install that as well. If you want to use the useAsync hook, you'll need react@16.8.0 or later.

Transpiling for legacy browsers

This project targets the latest ECMAScript version. Our packages on npm do not contain ES5 code for legacy browsers. If you need to target a browser which does not support the latest version of ECMAScript, you'll have to handle transpilation yourself. Usually this will automatically be handled by the framework you use (CRA, Next.js, Gatsby), but sometimes you may need to tweak your Webpack settings to transpile react-async with Babel.

To transpile node_modules with Babel you need to use a babel.config.js, for more information see Babel's documentation.

In your webpack.config.js make sure that the rule for babel-loader:

  • doesn't exclude node_modules from matching via the exclude pattern;

  • excludes core-js as it shouldn't be transpiled;

  • is passed the configFile option pointing to the babel.config.js file.

  test: /\.(js|jsx)$/,
  exclude: /\/node_modules\/core-js\//,
  use: [{
    loader: 'babel-loader',
    options: {
      configFile: './babel.config.js',
      // Caching is recommended when transpiling node_modules to speed up consecutive builds
      cacheDirectory: true,
