ln-700-project-bootstrap

Type: L1 Top Orchestrator Category: 7XX Project Bootstrap

Universal project bootstrapper with two modes: CREATE (generate production-ready project from scratch) or TRANSFORM (migrate existing prototype from any platform to production structure). Output: Clean Architecture, Docker, CI/CD, quality tooling.

---

Mode Selection

Aspect	CREATE	TRANSFORM
Input	Empty directory or target stack config	Existing project (Replit, StackBlitz, CodeSandbox, Glitch, custom)
Detection	No source files found	Source files + optional platform config detected
ln-820	SKIP (no deps to upgrade)	RUN (upgrade existing deps)
ln-720	SCAFFOLD + GENERATE	RESTRUCTURE + MIGRATE
ln-724	SKIP (no artifacts)	CONDITIONAL (if platform detected)
ln-730–780	RUN (same for both modes)	RUN (same for both modes)

---

Overview

Aspect	Details
Input	Empty directory (CREATE) or source project (TRANSFORM)
Output	Production-ready project with all infrastructure
Delegations	ln-820 (conditional) -> ln-720 -> ln-730 -> ln-740 -> ln-760 -> ln-770 -> ln-780

Phase 0: Technology Detection

Step 0.0: Mode Detection

Condition	Mode	Action
Empty directory (no source files)	CREATE	Ask user for target stack, project name, entities
Source files found	TRANSFORM	Auto-detect stack, scan for platform artifacts
Ambiguous (few files, unclear)	ASK	Present both options, let user choose

Step 0.1: CREATE Mode — User Input

Parameter	Required	Default	Example
Project name	Yes	—	MyApp
Target backend	Yes	—	.NET / Node.js / Python
Target frontend	Yes	—	React / Vue / Angular / Svelte
Database	Yes	—	PostgreSQL / MongoDB / MySQL
Main entities	No	User, Role (starter)	User, Product, Order

Step 0.2: Idempotency Pre-flight

If target directory contains existing files:

1. Detect existing structure (package.json, .csproj, etc.)
2. Warn user: "Target directory is not empty. Existing files may be overwritten."
3. Ask: Overwrite (replace all) / Merge (keep existing, add missing) / Abort

Step 0.3: Technology Detection (TRANSFORM mode) / Stack Config (CREATE mode)

Analyze project to detect tech stack before delegations.

Detection Rules

Frontend:
  React:
    - package.json contains "react"
    - Files: *.tsx, *.jsx with React imports
  Vue:
    - package.json contains "vue"
    - Files: *.vue
  Angular:
    - package.json contains "@angular/core"
    - Files: *.component.ts
  Svelte:
    - package.json contains "svelte"
    - Files: *.svelte

Backend:
  .NET:
    - *.csproj files exist
    - *.sln files exist
  Node.js:
    - package.json + (express|fastify|nest|koa)
    - tsconfig.json or jsconfig.json
  Python:
    - requirements.txt OR pyproject.toml OR setup.py
    - (fastapi|flask|django) in dependencies
  Go:
    - go.mod exists

Database:
  PostgreSQL:
    - DATABASE_URL contains "postgres"
    - docker-compose.yml contains "postgres"
  MongoDB:
    - MONGODB_URI in env
    - docker-compose.yml contains "mongo"
  MySQL:
    - DATABASE_URL contains "mysql"

ORM:
  Drizzle: drizzle.config.ts exists
  Prisma: prisma/schema.prisma exists
  EF Core: *.csproj references Microsoft.EntityFrameworkCore
  SQLAlchemy: "sqlalchemy" in requirements

Detection Output

Detected Stack:
  Frontend:
    Framework: React
    Version: 19.x
    Build Tool: Vite
    UI Library: shadcn/ui
    State: React Query

  Backend:
    Current: Node.js + Express
    Target: .NET 10 (user preference)
    ORM: Drizzle -> EF Core

  Database:
    Type: PostgreSQL
    Version: 17

  Structure:
    Type: Monolith (Prototype)
    Origin: replit | stackblitz | codesandbox | glitch | custom
    Target: Clean Architecture

Phase 1: Generate Transformation Plan

Based on detected stack, create detailed plan:

# Bootstrap Transformation Plan

## Source Analysis
- Frontend: React 19 + Vite + TypeScript
- Backend: Express + Drizzle (to be replaced with .NET)
- Database: PostgreSQL 17

## Transformations

### 1. Dependencies (ln-820)
- Upgrade React 18 -> 19
- Upgrade Vite 5 -> 6
- Add missing peer dependencies

### 2. Structure (ln-720)
- Move frontend to src/frontend/
- Create .NET backend: MyApp.Api, MyApp.Domain, etc.
- Migrate mock data from Drizzle to MockData classes

### 3. DevOps (ln-730)
- Create Dockerfile.frontend (multi-stage)
- Create Dockerfile.backend (.NET SDK)
- Create docker-compose.yml
- Create .github/workflows/ci.yml

### 4. Quality (ln-740)
- Configure ESLint (flat config)
- Add Prettier
- Setup Husky + lint-staged
- Create test infrastructure (Vitest, xUnit)

### 5. Security (ln-760)
- Scan for hardcoded secrets
- Run npm audit
- Create SECURITY.md

### 6. Crosscutting (ln-770)
- Configure Serilog logging
- Add GlobalExceptionMiddleware
- Configure CORS policy
- Add /health endpoints
- Enable Swagger

### 7. Verification (ln-780)
- Build all projects
- Run tests
- Start Docker containers
- Verify health checks

## Estimated Changes
- Files created: ~45
- Files modified: ~12
- Files deleted: ~8 (replaced backend)

---

Phase 2: User Confirmation

Present plan and ask for approval:

Bootstrap Plan Ready!

Summary:
- Frontend: React 19 (upgrade from 18)
- Backend: .NET 10 (replacing Node.js)
- Docker: Multi-container setup
- CI/CD: GitHub Actions
- Quality: ESLint, Prettier, Husky

Proceed with bootstrap? [Y/n]

If user declines, ask for modifications.

---

Phase 3: Execute Delegations

Sequential delegation to L2 coordinators:

Order	Skill	Purpose	CREATE mode	TRANSFORM mode	Depends On
1	ln-820	Upgrade dependencies	SKIP	RUN	—
2	ln-720	Structure (SCAFFOLD/RESTRUCTURE)	RUN (SCAFFOLD)	RUN (RESTRUCTURE)	ln-820
3	ln-730	Setup Docker/CI	RUN	RUN	ln-720
4	ln-740	Configure quality tools	RUN	RUN	ln-720
5	ln-760	Security scanning	RUN	RUN	ln-820
6	ln-770	Crosscutting concerns	RUN	RUN	ln-720
7	ln-780	Build and verify	RUN	RUN	All above

Delegation Protocol

For each L2 coordinator:

1. Prepare context:

   Stack:
     frontend: { framework, version, buildTool }
     backend: { framework, version }
     database: { type, version }
   
   Paths:
     root: /project
     frontend: /project/src/frontend
     backend: /project/src/MyApp.Api
   
   Options:
     skipTests: false
     allowFailures: false
   

2. Invoke skill: Pass context as input

3. Collect result:

   Status: success | partial | failed
   FilesCreated: [...]
   FilesModified: [...]
   Warnings: [...]
   Errors: [...]
   

4. Handle errors:

   • Log error details
   • Ask user: continue or abort?
   • If abort, rollback if possible

Phase 4: Generate Report

Bootstrap Completeness Assessment

Context: Final verification that bootstrap produced a working project, not just files.

#	Category	Check	Source
1	Structure	Clean Architecture layers present	ln-720 result
2	Dependencies	All packages installed, no version conflicts	ln-820 result
3	DevOps	Docker builds, CI pipeline valid	ln-730 result
4	Quality	Linters/formatters configured and pass	ln-740 result
5	Security	No hardcoded secrets, scanning configured	ln-760 result
6	Build	Project compiles/builds without errors	ln-780 result

Completeness Score = count of PASS / 6

• 6/6: Bootstrap complete
• 4-5/6: Bootstrap complete with warnings (list failing categories)
• <4/6: Bootstrap incomplete — list blocking issues for user action

Summary Report

Final summary after all delegations:

Bootstrap Complete!
