Vendix Monorepo Workspaces

Purpose

Use this skill for npm workspaces, dependency placement, app package boundaries, Docker build contexts, and CI/CD commands. Architecture ownership belongs to vendix-core.

Current Workspace Map

| Workspace | Path | Notes | | --- | --- | --- | | Backend | apps/backend | NestJS API with its own dependencies and Dockerfiles | | Frontend web | apps/frontend | Angular app with its own dependencies and Dockerfiles | | Mobile | apps/mobile | Expo/React Native app with its own dependencies | | Shared types | libs/shared-types | Local package consumed by apps, e.g. @vendix/shared-types |

Root package.json orchestrates scripts and workspaces. Production/runtime dependencies should normally live in the workspace that imports them. Root dependencies should be treated as exceptions and reviewed before adding more; the current repo already has at least one root runtime exception, so do not assume dependencies is empty.

Dependency Rules

• If code in one workspace imports a package, that workspace must declare the dependency.
• If frontend and backend both import the same package, install it in both workspaces.
• If mobile imports a package, install it in apps/mobile.
• Shared libraries should declare their own package metadata and avoid hidden app dependencies.
• Root should mainly contain orchestration scripts and shared dev tooling, unless an explicit repo-level exception is required and documented.
• Do not rely on hoisting as the reason a workspace can build.

Commands

# Install all workspaces from root
npm install

# Install in a specific workspace
npm install <package> -w apps/frontend
npm install <package> -w apps/backend
npm install <package> -w apps/mobile

# Run workspace scripts
npm run start -w apps/frontend
npm run start:dev -w apps/backend
npm run start -w apps/mobile

# Root orchestration scripts
npm run dev
npm run mobile:start
npm run mobile:ios
npm run mobile:android

Do not run production build commands unless the human explicitly requests production verification; use buildcheck-dev for normal development verification.

Docker Rules

• Docker build contexts for app containers should point at the workspace, not the repo root.
• Current dev containers use apps/backend/Dockerfile.dev and apps/frontend/Dockerfile.dev.
• Backend and frontend containers mount their workspace and isolate /app/node_modules.
• Mobile currently does not have a Dockerfile in this repo; treat mobile Dockerization as a knowledge gap unless added intentionally.

Current compose services include db, redis, backend, frontend, nginx, and docker-cleanup.

Docker Commands

# Start development services
docker compose up -d

# Rebuild services after Dockerfile/package changes
docker compose up --build -d

# Stop services
docker compose down

Prefer the root docker scripts already present in package.json when useful: docker:up, docker:rebuild, docker:down, docker:down-v.

Use buildcheck-dev for log-based verification after development changes.

CI/CD Rules

• Install dependencies from root with workspace-aware npm commands.
• Build or lint the specific workspace being validated.
• Keep Docker image builds scoped to the app workspace unless the Dockerfile explicitly requires repo context.
• Do not add root-level production dependencies to make CI pass; fix the workspace package instead.

Adding Or Removing Workspaces

When adding a workspace:

1. Place it under apps/ or libs/ so root workspaces detect it.
2. Give it its own package.json with accurate dependencies.
3. Add root scripts only when cross-team orchestration is useful.
4. Add or update app-specific skills if the workspace introduces new patterns.

When removing a workspace:

1. Remove root scripts that reference it.
2. Remove dependent workspace references and local file dependencies.
3. Run npm install from root to update the lockfile.

Verification

• Check the importing workspace declares each package it uses.
• Check root package.json did not gain unnecessary production dependencies.
• Check Docker contexts still match docker-compose.yml.
• Run ./skills/skill-sync/assets/sync.sh and ./skills/setup.sh --sync after skill metadata changes.
