Hi there!

First of all, thanks for all the amazing work that goes into maintaining create-react-app and react-scripts. We've seen a lot of success with teaching it at @upleveled.

Recently came across @​typescript-eslint/no-floating-promises (from tweets like https://mobile.twitter.com/flybayer/status/1469098848958222337) and it has problems with the code in reportWebVitals.js

This avoids the issue without changing the functionality

By the way, also happy to add a proper catch callback here, if it's so wished.

@raix raix added this to the 5.0.1 milestone Dec 21, 2021

.catch(() => {});

This seems like a good fix for this issue but if there is a real error with the import it will be swallowed. Can you catch and log any error that might happen instead?

Yep, for sure, I'll just use console.error then
