perf(wrangler): remove execa by 43081j · Pull Request #12369 · cloudflare/workers-sdk

43081j · 2026-02-02T17:32:49Z

This removes execa and uses the much smaller, more modern tinyexec
instead.

Reasoning:

execa 640KB vs tinyexec 26KB
execa 23 packages vs tinyexec 1 package
tinyexec is widely adopted by most of the modern CLIs today (tsdown,
vite, vitest, storybook, etc.)

Part of #11854.

Tests
- Tests included/updated
- Automated tests not possible - manual testing has been completed as follows:
- Additional testing not necessary because:
Public documentation
- Cloudflare docs PR(s): N/A
- Documentation not necessary because: Internal code change only

Thanks, @43081j!

The windows CI job appears to keep hanging but also this needs another rebase.

43081j · 2026-02-03T22:41:46Z

Strange. When I'm next on a Windows machine I can try run them locally and see what happens if that helps

This removes `execa` and uses the much smaller, more modern `tinyexec` instead. Reasoning: - `execa` 640KB vs `tinyexec` 26KB - `execa` 23 packages vs `tinyexec` 1 package - `tinyexec` is widely adopted by most of the modern CLIs today (tsdown, vite, vitest, storybook, etc.) Part of cloudflare#11854.

Hi @43081j — we're doing some cleanup of stale draft PRs.

This PR has been quiet since 2026-02-13. Could you let us know within 14 days whether you're still planning to continue?

If yes: please leave a comment with a status update or push a rebase, and we'll keep it open.
If no: no need to reply — we'll close it after 14 days, and you can always reopen later if you pick it back up.

Thanks!

It looks like the change here is resulting in the test failures.
