feat(compute): use Composer and Prisma 8 in templates

[AmanVarshney01]

Purpose of change

Move the three Compute starter templates to Prisma 8 and Composer so one-click deployments provision their full stack from the repository.

What's changed and why

• Replace prisma.compute.json and classic Prisma ORM setup in Hono, Next.js, and TanStack Start with root Composer modules and Prisma 8 contracts.
• Declare Prisma Postgres, Compute, and the database dependency binding in each module.ts.
• Add .github/workflows/prisma-deploy.yml to every template with GitHub OIDC and prisma/cloud-deploy-action@v1 for deploy and teardown.
• Update dependencies and lockfiles to Prisma 8, @prisma/orm-postgres, and the Composer packages.
• Point each Composer service at the framework's real build output; the Hono paths were verified through a real isolated Composer deployment.
• Make the Compute source test install locked dependencies and build all three templates, so CI catches invalid service output paths before merge.

Testing notes / Before-after

• Before: the templates relied on Console database provisioning, injected DATABASE_URL, and the classic build-runner config.
• After: the copied repository's Composer workflow provisions Prisma Postgres and Compute, then binds the database to the service.
• npm test -- tests/compute.test.ts
• bun run build in compute/hono
• bun run build in compute/nextjs
• bun run build in compute/tanstack-start
• A real isolated Hono Composer deployment succeeded and its exact stage was destroyed afterward.

Rollout

• Companion Console PR: https://github.com/prisma/pdp-control-plane/pull/4928
• Merge and deploy the Console PR first. Then merge this PR immediately afterward.
• During the gap, the Console preflight rejects the old templates before creating a repository or project. There is no classic fallback.

Summary by CodeRabbit

• New Features

  • Added Prisma 8 Compute examples for Hono, Next.js, and TanStack Start.
  • Applications now provision PostgreSQL databases and services through Prisma Composer.
  • Added typed database contracts, schema update workflows, and sample seed data.
  • Added automated deployment and teardown for branch-based Prisma Cloud environments.

• Documentation

  • Updated setup and deployment guidance for contract emission, migrations, database initialization, and Composer.

• Tests

  • Enhanced template validation, dependency installation, builds, and deployment workflow checks.

Walkthrough

The Hono, Next.js, and TanStack Start Compute examples now use Prisma 8 contracts, typed ORM clients, Prisma Composer modules, Prisma Cloud services, and GitHub Actions deployment workflows. Legacy Prisma generation, migration, and Compute configuration files were removed.

Changes

Prisma Compute Composer migration

Layer / File(s)	Summary
Prisma contract definitions compute/*/src/prisma/contract.*, compute/*/src/prisma/composer.ts	Each example now defines a Prisma 8 contract and generated typed metadata for the Post and User models.
Typed database access and queries compute/*/src/prisma/db.ts, compute/*/src/prisma/seed.ts, compute/hono/src/index.ts, compute/nextjs/src/app/api/users/route.ts, compute/tanstack-start/src/routes/*	Database access uses cached getDb() clients and the fluent ORM API. Seed scripts upsert Alice and Marie with published posts.
Composer configuration and service wiring compute/*/module.ts, compute/*/service.ts, compute/*/prisma-*.ts, compute/*/package.json, compute/*/bunfig.toml	Composer provisions PostgreSQL and application services. Scripts and dependencies now use contract emission, Prisma Next commands, and Composer packages.
Deployment workflows and example instructions compute/*/.github/workflows/*, compute/*/README.md, compute/README.md	Documentation and workflows now describe Composer deployment, contract updates, branch deployment, and branch teardown.
Template installation and build validation tests/compute.test.ts	Template validation checks Composer files, contract tooling, deployment workflows, installation, and builds.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 081e1

The templates use inconsistent specifier forms for the same generated declaration file, so builds or type checking may depend on module-resolution settings that are not consistently defined. The PR is otherwise mergeable, but owners should resolve or explicitly accept this bounded correctness risk.

3-3: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Use one contract type import specifier form in all three templates. The three composer.ts files import the same generated declaration file with two different specifier forms. ./contract.d.js resolves under nodenext. ./contract.d resolves only under bundler or legacy Node resolution. Pick the form that matches each template's moduleResolution setting, and keep the templates consistent.

• compute/hono/src/prisma/composer.ts#L3-L3: confirm this template sets a moduleResolution value that resolves ./contract.d.js, or change the specifier to match the other two templates.
• compute/nextjs/src/prisma/composer.ts#L3-L3: confirm this template sets moduleResolution to bundler, or change the specifier to ./contract.d.js.
• compute/tanstack-start/src/prisma/composer.ts#L3-L3: confirm this template sets moduleResolution to bundler, or change the specifier to ./contract.d.js.

Inline comments:
In `@compute/hono/.github/workflows/prisma-deploy.yml`:
- 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.
