There are approaches to include polyfills in create-react-app,
-
Manual import from
core-js
:Create a file called (something like)
polyfills.js
and import it into rootindex.js
file. Runnpm install core-js
oryarn add core-js
and import your specific required features.import 'core-js/fn/array/find';import 'core-js/fn/array/includes';import 'core-js/fn/number/is-nan'; -
Using Polyfill service:
Use the polyfill.io CDN to retrieve custom, browser-specific polyfills by adding this line to
index.html
:<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=default,Array.prototype.includes"></script>In the above script we had to explicitly request the
Array.prototype.includes
feature as it is not included in the default feature set.
