Tech Stack

Layer	Technology
Frontend	Angular 18, Angular Material, RxJS, Socket.IO Client
Backend	Node.js, TypeScript, Fastify, Socket.IO
Database	SQLite (via better-sqlite3)
Config	YAML software plugin definitions

Prerequisites

• Node.js 20+
• npm 10+

Getting Started

1. Backend Setup

cd backend
npm install
npm run dev

The API server starts at http://localhost:3001.

2. Frontend Setup

cd frontend
npm install
npm start

The Angular app starts at http://localhost:4200.

API Endpoints

Method	Endpoint	Description
GET	/api/health	Health check
GET	/api/catalog	List all installable software
GET	/api/catalog/platform/:os	Software filtered by platform
POST	/api/installations	Create installation session
GET	/api/installations/:id	Get installation status
POST	/api/installations/:id/start	Start installing
POST	/api/installations/:id/retry/:taskId	Retry a failed task
GET	/api/installations/:id/logs	Get task logs
POST	/api/licenses/validate	Validate software licenses

WebSocket Events

Event	Direction	Payload
join-installation	Client → Server	installationId
progress	Server → Client	{ taskId, softwareId, status, progress }
log	Server → Client	{ taskId, softwareId, message, progress }
installation-complete	Server → Client	{ installationId }

Code Flow

Installation Flow (Backend)

1. POST /api/installations
   → InstallationService.create()
   → Resolves dependency order (DAG)
   → Creates tasks in DB (status: pending)

2. POST /api/installations/:id/start
   → InstallationService.start()
   → Executes tasks sequentially
   → For each task:
     a. Update status → in-progress, emit via Socket.IO
     b. Execute platform install command
     c. Emit log events with progress
     d. Update status → completed/failed

3. WebSocket emits progress to all clients in the installation room

User Flow (Frontend)

1. /setup page loads
   → CatalogService.getAll() fetches software list
   → User selects platform + software

2. User clicks "Start Installation"
   → InstallationService.create() → gets installationId
   → Navigate to /progress/:installationId

3. Progress page mounts
   → WebSocketService.connect() + joinInstallation()
   → InstallationService.start() triggers backend
   → Real-time progress updates flow via Socket.IO
   → UI updates task cards live

4. Installation completes
   → 'installation-complete' event received
   → Summary shown

Adding New Software

Create a YAML file in backend/plugins/:

name: terraform
displayName: Terraform
category: Infrastructure
version: "1.7"
id: terraform
dependencies: []
platforms:
  macos:
    manager: brew
    command: "brew install terraform"
    verify: "terraform --version"
  linux:
    manager: apt
    command: "sudo apt-get install -y terraform"
    verify: "terraform --version"
  windows:
    manager: winget
    command: "winget install Hashicorp.Terraform"
    verify: "terraform --version"
license:
  type: open-source
  spdx: MPL-2.0

Development

# Run backend in watch mode
cd backend && npm run dev

# Run frontend dev server
cd frontend && npm start
