| # Calypso Polyfills | |
| This package includes several configurations for required polyfills for Calypso, targeting two different environments: node, and browsers. | |
| ## Features | |
| `calypso-polyfills` ties into the Calypso build process, to ensure that only the required polyfills for each build target are needed. Through the use of Babel's `preset-env` and `browserslist` configurations, we strip out any polyfills that are supported for all browsers that are supported by that build target. | |
| See the root directory's `package.json` for the list of supported browsers for each build target. | |
| ## Usage | |
| In Node.js, simply require the package: | |
| ```js | |
| require( '@automattic/calypso-polyfills' ); | |
| ``` | |
| In a browser, a similar naked import will include the polyfills: | |
| ```js | |
| import '@automattic/calypso-polyfills'; | |
| ``` | |
