Reproduce this snapshot
In this repository with its locked dependencies, run:
pnpm exec tsx src/lib/flavio-ops-measure.tsThe script measures each package separately without executing its exports. Compare versions before comparing sizes.
How to use this tool
Filter the snapshot and inspect versions. Measure your actual application imports before choosing a dependency.
When not to use it
Namespace all-exports snapshots are not real application bundles. Functional alternatives are suggestions, not equivalent drop-in replacements.
