WalkthroughThe Hono, Next.js, and TanStack Start examples migrate to Prisma 8 contracts, typed ORM clients, Prisma Composer configuration, and branch-based Compute deployment. Documentation, package scripts, generated contracts, and template validation are updated. ChangesPrisma Compute Composer examples
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The templates now deploy through Composer and Prisma 8, but differing declaration-file imports may cause template-specific type-resolution failures, while the new verification test can leak generated files or pass against an unrelated listener. The PR is mergeable with explicit owner follow-up on these bounded issues. Sequence Diagram(s)sequenceDiagram

- Around line 7-9: Update the concurrency group expressions in
compute/hono/.github/workflows/prisma-deploy.yml lines 7-9 and
compute/nextjs/.github/workflows/prisma-deploy.yml lines 7-9 to use
github.event.ref for delete events and github.ref_name for push events, ensuring
deployment and teardown for the same branch share a concurrency group.
Apply the same fix in
`@compute/tanstack-start/.github/workflows/prisma-deploy.yml` around lines 7 - 9:
The same concurrency-key mismatch applies to the TanStack Start workflow.
In `@compute/README.md`:
- Around line 12-19: Update the deployment documentation in README.md to state
that the Console companion PR must be merged and deployed before users run the
example deployment workflows. Place this prerequisite before the workflow
instructions, without changing the existing Prisma or Composer version guidance.

Move the three templates from @prisma/composer@0.6.0-dev.20 /
@prisma/orm-postgres@8.0.0-rc.1 to the released, mutually pinned toolchain:
@prisma/composer and @prisma/composer-prisma-cloud 0.10.0,
@prisma/orm-postgres 8.0.0-rc.4, and the consolidated prisma CLI 8.0.0-rc.6
as a devDependency.
The rc.1 pin existed to keep the prisma-next bin, which orm-postgres dropped
after rc.1; every ORM and cloud script now runs the consolidated CLI's local
prisma bin instead. The prisma-next.config.ts files become prisma.config.ts
wrapped in definePrismaConfig, the shape the consolidated CLI discovers and
Composer 0.10.0 loads through orm-toolchain's config loader.
Add @prisma/composer-cli@0.10.0 as a devDependency: the templates shipped no
local prisma-composer bin, so prisma/cloud-deploy-action fell back to its own
npx default (composer-cli 0.7.0) and deploys ran a different Composer version
than the one the app depends on — and would silently change again whenever
the action's default moves.
Fix the Hono service to the directory build form. At 0.10.0 the single-file
node({ module, entry }) form copies exactly one file into the bundle and only
the directory form stages the traced runtime dependencies, so the tsc output
(entry plus sibling files plus node_modules) crashed on boot with the old
shape. Verified by assembling the bundle through
@prisma/composer/node/control and booting it: the server starts and serves
requests.
Re-emit the committed contracts with the rc.4 emitter and make the compute
test fail on stale contracts: every build re-emits, so a git diff after the
build catches a contract.prisma edit committed without re-emitting.

The compute test built the templates but never assembled a deploy bundle, so a build that Composer cannot turn into a bootable service still passed CI — exactly how the Hono single-file bundle defect got through: the framework build succeeded while the assembled bundle was missing its sibling files and crashed on boot. After each build, assemble the service through the same control assembler a deploy uses (resolved from the build adapter's extension), boot the bundle entry with node, and require an HTTP response on its port. Any status counts: without a database the app may answer 500, but a broken bundle exits or never answers. The script runs from the template root with the template's own tsx so every import resolves against the template's locked dependencies. Verified both directions: all three templates answer, and reverting Hono to the single-file form makes the check fail with 'exited before serving'.

In `@tests/compute.test.ts`:
- Around line 35-66: Wrap the assemble, child-process startup, and endpoint
polling flow in a try block, and move child termination plus removal of
.prisma-composer into a finally block so cleanup runs when control.assemble or
any later step throws. Use the existing child and bundle lifecycle in the test
without changing its polling behavior.
- Line 57: Update the bundle verification flow around the fetch calls at the
existing verification sites to allocate an unused port for each invocation, pass
that port to the assembled bundle, and fetch from the same dynamically allocated
port. Remove reliance on predictable ports such as 4310 + templateIndex so an
unrelated listener cannot satisfy the success check.
