Summary
Hi everyone,
I'm using Turborepo in a monorepo and exploring whether it's possible to reuse the build cache generated in CI during the CD (deployment) stage.
In my setup using GitHub Actions,
- CI runs when a pull request is opened against the
mainbranch. - CD runs when that pull request is merged into
main.
Since both workflows build from the same commit and same environment, I expected the remote cache uploaded in CI to be reused in CD.
I've tested this, and it seems to work for some packages — for example, a UI package built with plain TypeScript correctly hits the remote cache in CD.
However, Next.js packages consistently miss the cache, even though nothing changes between the two builds.
❓ Question
Has anyone successfully reused CI-generated remote cache in CD with Turborepo?
Would love to hear about setups where this works reliably — especially with Next.js apps.
Thanks!
