Runtime Bootstrap

After project generation, the following commands and prerequisites must work in order so that the application runs without ad-hoc auth or database setup.

The generator must produce a runnable development environment consisting of:

external Keycloak identity provider
backend API
frontend SPA
PostgreSQL database

Runtime bootstrap assumes the application was generated from domain/*.dsl plus optional non-duplicating overrides only. There is no separate DTO/API/UI DSL bootstrap step.

The generator must also produce the runtime artifacts required to bootstrap auth from zero, including a root-level Keycloak realm import artifact. The repository default example filename is toir-realm.json, but future generations must allow a project-specific equivalent.

Bootstrap Sequence

1. Prepare Keycloak

Before starting the application, ensure an external Keycloak server is reachable and import or verify the generated realm artifact:

root-level generated Keycloak realm import artifact
repository default example filename: toir-realm.json

The runtime instructions must require importing or verifying this realm before frontend/backend startup.

Keycloak bootstrap expectations:

realm import is self-contained
frontend client exists
backend audience client exists
realm roles exist
issued access tokens reliably contain sub, aud, and realm_access.roles

The generator must not rely on undeclared built-in client scopes magically existing after realm import.

2. Start the database

From the project root:

docker compose up -d

This starts the PostgreSQL container. The backend connects to it using DATABASE_URL from server/.env.

3. Backend setup and start

cd server
npm install
npx prisma generate
npx prisma migrate dev
npx prisma db seed
npm run start

npm install installs dependencies and runs postinstall if configured.
npx prisma generate ensures Prisma client is generated explicitly after install or schema changes.
npx prisma migrate dev creates/applies migrations.
npx prisma db seed inserts minimal development data.
npm run start starts the NestJS server.

Backend startup requirements:

required database and auth env vars must be present
startup must fail fast if required env vars are missing
CORS must support the SPA -> API bearer-token model
/health must remain public

4. Frontend setup and start

In a separate terminal, from the project root:

cd client
npm install
npm run dev

npm install installs frontend dependencies including keycloak-js.
npm run dev starts the Vite dev server.

Frontend startup requirements:

required Vite auth vars must be present
startup must fail fast if required auth vars are missing
Keycloak must initialize before the SPA is rendered
login must use redirect-based Keycloak authentication only

Success Criteria

After completing the bootstrap sequence:

Keycloak is reachable and the generated realm has been imported or verified.
Database container is running and Prisma can connect.
Backend responds on /health without auth.
Protected backend routes require a valid bearer token.
Frontend loads, redirects through Keycloak login when needed, and uses bearer auth for all API calls.

The generator is responsible for producing all artifacts and instructions needed for this sequence:

docker-compose.yml
schema
migrations
seed
backend/frontend env examples
health endpoint
auth infrastructure
root-level Keycloak realm import artifact

Docker scope must remain limited to PostgreSQL. Keycloak remains an external dependency in this repository.
