chore: Add size limit reports on PRs for Cloudflare by JPeer264 · Pull Request #20055 · getsentry/sentry-javascript

JPeer264 · 2026-03-31T12:26:58Z

Cloudflare does have a free tier limit of 3mb: https://developers.cloudflare.com/workers/platform/limits/#worker-size

It would be too bad if we ship something for Cloudflare and by accident ship something which is super costly. For now our size is ~30kb and added a limit to 50kb.

looks like some other commits made it to this branch 🤔 😅

also, no objections to adding a size limit entry! Just to check: when you add the SDK to cloudflare workers (or other components): Does this roughly equate to the same size? Just wondering if we're missing any dependencies/node_modules data that might make the SDK's footprint larger in reality than the size check shows

Ok the auto rebase function from GitHub doesn't work as expected :D

~~Theoretically we are depending on @sentry/core and maybe in the future @sentry/node or @sentry/node-core. Wouldn't that be automatically added here?~~

There is indeed something missing. I'll try to add it

JPeer264 · 2026-04-07T14:10:35Z

Converting to draft, as for Cloudflare we have to use esbuild to show the actual numbers. Unfortunately size-limit only accepts one bundler at a time, which means that the others have to use esbuild as well.

I opened an issue to see if it would be possible to have two bundlers in one size-limit file
