Size Analysis for JS SDK

[rodolfoBee]

Problem Statement

Sentry recently released Size Analysis for mobile applications. Bundle sizes are also important for web applications(we have a history of requests regarding our own bundle size). Bringing the advantages of Size Analysis to the web ecosystem will benefit lots of Sentry users.

Solution Brainstorm

Implement the feature for frontend SDKs.

I think this would be a new feature we'd need to scope out carefully. As in:

• what's the value we provide (e.g can we do more than CodeCovs attempt with bundle size monitoring)
• can we provide the same actionability as mobile app size analysis
• especially with keeping in mind that most bundles are minified and we need source maps to reconstruct e.g. dependency usage
• etc

I don't think tracking this as an issue for now is the best way, so I'll convert this to a GH discussion. But I'd like to monitor it and see how many upvotes/reactions this receives. Furthermore, if anyone has concrete suggestions, please comment!
