How to reduce bundle size?

[Parnswir]

Thanks to your awesome package, I could finally get all of my firebase-auth-related use-cases to work in Next. However, I noticed the bundle size (aka next build's "First Load JS shared by all") has doubled from ~64k to ~133k just by following the tutorial.

Is this common/expected? Can you point to any obvious mistakes one can make?

This package's built code is 10kb on the client side and 21kb on the server side, so that difference probably includes other dependencies. Can you analyze the bundles before/after to see what's added?

hmm, you're right. It looks like firebase-auth's auth.esm.js is the culprit. So I guess there's no way around the larger bundle with your library or without. Thanks for the quick answer!

It looks like there is hope on the horizon: firebase/firebase-js-sdk#4368
