Angular-based user interface for the TMI application.

TMI (Threat Modeling Improved) is a server based threat modeling web application.

• TMI makes threat modeling easier and more accurate with real-time colloboration
• TMI makes threat modeling faster and less toilsome with agent-driven or agent-assisted threat model creation
• TMI uses your workflows - it fits into your existing security tool chains

• Full REST API - threat models and their associated data flow diagrams (DFDs) and threats are human- and machine-readable and editable
  • OpenAPI 3.0 specification
• Threats, threat models, diagrams and objects can be extended with arbitrary key-value metadata
• Real-time collaborative diagram editing
• Role-based access control (reader, writer, owner)
• OAuth authentication with configurable OAuth providers
• Supports multiple threat model frameworks (STRIDE, CIA, etc.)
• Supports integration with issue tracking systems
• Apache licensed for customizability
• LLM & agentic functionality will be a separate component under a different license

The associated back-end server, written in Go, is called TMI.

• Clone this repo and change to the repo root
• Download and install Node.js (latest LTS version recommended; I use 20.19.2)
• Download and Install pnpm

# Install dependencies
pnpm install

# Start application server
pnpm run dev

The application supports multiple environment configurations:

1. Default Configuration

   pnpm run dev  # Uses environment.ts file; this starts the app listening on port 4200

2. Environment-specific Configurations

   pnpm run dev:staging  # Uses environment.staging.ts file
   pnpm run dev:test     # Uses environment.test.ts file
   pnpm run dev:prod     # Uses environment.prod.ts file
   pnpm run dev:local    # Uses environment.local.ts file

3. Custom Configuration with Environment Variables

   # Set environment variables first
   export TMI_INTERFACE=0.0.0.0    # Listen on all interfaces
   export TMI_PORT=8080            # Custom port
   export TMI_SSL=true             # Enable HTTPS
   export TMI_SSL_KEY=./certs/key.pem    # Path to SSL key
   export TMI_SSL_CERT=./certs/cert.pem  # Path to SSL certificate
   
   # Run with custom configuration
   pnpm run dev:custom

Environment files are located in src/environments/. The application uses:

• environment.ts - Default environment
• environment.dev.ts - Development environment (when configured)
• environment.local.ts - Local development environment
• environment.prod.ts - Production environment
• environment.staging.ts - Staging environment
• environment.test.ts - Test environment
• environment.example.ts - Example with documentation

To create a custom environment:

1. Copy environment.example.ts to a new file (e.g., environment.custom.ts)
2. Configure values as needed - at a minimum you need to configure apiUrl to your development TMI server, typically http://localhost:8080
3. Update angular.json with a new configuration if needed

# Development build
pnpm run build

# Production build
pnpm run build:prod

All important commands for building, linting, testing, file validation, and a lot of utilities are exposed through pnpm scripts.

Get a list of pnpm scripts with pnpm run.
