nean-scaffold

name	nean-scaffold
description	Scaffold an Nx monorepo with NestJS API, Angular frontend, and shared libraries.
argument-hint	[app-name] [--github] [--public] [--org <org>] [--repo <n>] [--no-push]
allowed-tools	Bash, Write, Read, Glob, Grep

Purpose

Create a fully working NEAN repo (NestJS + Angular + Nx + TypeORM + PrimeNG) with tooling configured and runnable immediately.

Arguments

• app-name — Project folder name (default: "app")
• --github — Create GitHub repo and push (requires gh auth)
• --public — Make GitHub repo public (default: private)
• --org <n> — Create under org instead of personal account
• --repo <n> — Override repo name (default: app-name)
• --no-push — Create repo and commit but don't push

Template-first rule

Copy files from templates/ into the project. If a template doesn't exist, generate equivalent content.

Templates provide:

• Root configs (nx.json, tsconfig, eslint, prettier, CI)
• API utilities (exception filters, validation pipes, response helpers)
• Shared types structure
• Database module with TypeORM config
• Docker configuration
• CLAUDE.md for the new repo
• VS Code workspace settings and extension recommendations

Scaffold steps

1. Create Nx workspace from parent dir (creates subdirectory): npx create-nx-workspace@latest <app-name> --preset=apps --nxCloud=skip --interactive=false --skipGit --packageManager=npm 1a. Copy VS Code config from templates: .vscode/settings.json and .vscode/extensions.json
2. Install Nx plugins: npm install -D @nx/nest @nx/angular @nx/js
3. Add NestJS: npx nx g @nx/nest:application apps/api --e2eTestRunner=none

   The NestJS generator does NOT create jest config. Add API test infrastructure manually after generation (see step 3a). 3a. Add API test infrastructure (NestJS generator omits this):

   • apps/api/jest.config.cts — copy pattern from libs/shared/types/jest.config.cts, change displayName, adjust preset path to ../../jest.preset.js, add moduleNameMapper for all @<app-name>/* aliases
   • apps/api/.spec.swcrc — copy verbatim from libs/shared/types/.spec.swcrc (enables decorator metadata for NestJS DI)
   • apps/api/tsconfig.spec.json — standard Nx spec tsconfig with jest + node types, referencing tsconfig.app.json
   • apps/api/tsconfig.json — add { "path": "./tsconfig.spec.json" } to references array
4. Add Angular: NX_IGNORE_UNSUPPORTED_TS_SETUP=true npx nx g @nx/angular:application apps/web --style=scss --routing --e2eTestRunner=playwright --prefix=app

   Set NX_IGNORE_UNSUPPORTED_TS_SETUP=true before running Angular generators when Nx uses TypeScript project references.

5. Override Angular tsconfig: Set composite: false, declaration: false, declarationMap: false, isolatedModules: false in apps/web/tsconfig.json and add "dom" to lib. Angular's compiler is incompatible with TypeScript project references settings.
6. Add shared libraries from templates
7. Configure TypeORM and database module
8. Add PrimeNG 21+ and Tailwind CSS v4 to Angular:
   • Create apps/web/postcss.config.js with plugin

Quality gates (must pass before done)

npm install
npm run lint
npm run test
npm run build
npm run e2e

Teardown after E2E / smoke tests

If the dev server ran against a live database (TypeORM synchronize: true creates tables automatically), clean up afterward:

1. Stop the dev server — kill the nx serve process
2. Drop smoke-test tables — psql -U postgres -d <db> -c 'DROP TABLE IF EXISTS <table>;'
3. Verify clean state — psql -U postgres -d <db> -c '\dt' should show only pre-existing tables (e.g. migrations)
4. Confirm port is free — lsof -i :3000 should return nothing

This prevents leftover tables from interfering with future migration-based workflows.

GitHub setup (if --github)

• Requires gh auth status to succeed
• Creates repo: gh repo create <owner>/<repo> --<visibility> --source . --remote origin
• Commits and pushes unless --no-push

Post-scaffold: GitHub security (recommended)

After scaffolding, run these skills to complete GitHub security setup:

1. /github-hooks --platform nean — Install local Git hooks

   • Husky + lint-staged for pre-commit validation
   • Commit message enforcement (conventional commits)
   • Secret scanning (gitleaks)
   • Pre-push test runs

2. /github-secure (if --github was used) — Configure repo security via API

   • Branch protection rules
   • Dependabot alerts & security updates
   • Auto-merge enablement
   • (Note: .github/ config files are created during scaffold, not github-secure)

These are invoked automatically by /nean-kit.

Output

Summarize: structure created, commands available, what tooling is included, GitHub status if applicable, and remind to run github-hooks/github-secure if not using nean-kit.
