This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is the Unraid API monorepo containing multiple packages that provide API functionality for Unraid servers. It uses pnpm workspaces with the following structure:

  • /api - Core NestJS API server with GraphQL
  • /web - Nuxt.js frontend application
  • /unraid-ui - Vue 3 component library
  • /plugin - Unraid plugin package (.plg)
  • /packages - Shared packages and API plugins

Essential Commands

Development

pnpm install              # Install all dependencies
pnpm dev                  # Run all dev servers concurrently
pnpm build                # Build all packages
pnpm build:watch          # Watch mode with local plugin build

Testing & Code Quality

pnpm test                 # Run all tests
pnpm lint                 # Run linting
pnpm lint:fix             # Fix linting issues
pnpm type-check           # TypeScript type checking

API Development

cd api && pnpm dev        # Run API server (http://localhost:3001)
cd api && pnpm test:watch # Run tests in watch mode
cd api && pnpm codegen    # Generate GraphQL types

Deployment

pnpm unraid:deploy <SERVER_IP>  # Deploy all to Unraid server

Developer Tools

unraid-api developer                       # Interactive prompt for tools
unraid-api developer --sandbox true        # Enable GraphQL sandbox
unraid-api developer --sandbox false       # Disable GraphQL sandbox
unraid-api developer --enable-modal        # Enable modal testing tool
unraid-api developer --disable-modal       # Disable modal testing tool

Architecture Notes

API Structure (NestJS)

  • Modules: auth, config, plugins, emhttp, monitoring
  • GraphQL API with Apollo Server at /graphql
  • Redux store for state management in src/store/
  • Plugin system for extending functionality
  • Entry points: src/index.ts (server), src/cli.ts (CLI)

Key Patterns

  • TypeScript imports use .js extensions (ESM compatibility)
  • NestJS dependency injection with decorators
  • GraphQL schema-first approach with code generation
  • API plugins follow specific structure (see api/docs/developer/api-plugins.md)

Authentication

  • API key authentication via headers
  • Cookie-based session management
  • Keys stored in /boot/config/plugins/unraid-api/

Development Workflow

  1. Work Intent required before starting development
  2. Fork from main branch
  3. Reference Work Intent in PR
  4. No direct pushes to main

Debug Mode

LOG_LEVEL=debug unraid-api start --debug

Enables GraphQL playground at http://tower.local/graphql

Coding Guidelines

General Rules

  • Never add comments unless they are needed for clarity of function
  • Never add comments for obvious things, and avoid commenting when starting and ending code blocks
  • Be CONCISE, keep replies shorter than a paragraph if at all possible

API Development Rules (api/**/*)

  • Use pnpm ONLY for package management
  • Always run scripts from api/package.json unless requested
  • Prefer adding new files to the NestJS repo located at api/src/unraid-api/ instead of the legacy code
  • Test suite is VITEST, do not use jest
  • Run tests with: pnpm --filter ./api test
  • Prefer to not mock simple dependencies

Web Development Rules (web/**/*)

  • Always run pnpm codegen for GraphQL code generation in the web directory
  • GraphQL queries must be placed in .query.ts files
  • GraphQL mutations must be placed in .mutation.ts files
  • All GraphQL under web/ must follow this naming convention

Testing Guidelines

General Testing Best Practices

  • Error Testing: Use .rejects.toThrow() without arguments to test that functions throw errors. Don't test exact error message strings unless the message format is specifically what you're testing
  • Focus on Behavior: Test what the code does, not implementation details like exact error message wording
  • Avoid Brittleness: Don't write tests that break when minor changes are made to error messages, log formats, or other non-essential details
  • Use Mocks Correctly: Mocks should be used as nouns, not verbs.

Vue Component Testing

  • This is a Nuxt.js app but we are testing with vitest outside of the Nuxt environment
  • Nuxt is currently set to auto import so some vue files may need compute or ref imported
  • Use pnpm when running terminal commands and stay within the web directory
  • Tests are located under web/__test__, run with pnpm test
  • Use mount from Vue Test Utils for component testing
  • Stub complex child components that aren't the focus of the test
  • Mock external dependencies and services
  • Test component behavior and output, not implementation details
  • Use createTestingPinia() for mocking stores in components
  • Find elements with semantic queries like find('button') rather than data-test IDs
  • Use await nextTick() for DOM updates
  • Always await async operations before making assertions

Store Testing with Pinia

  • Use createPinia() and setActivePinia when testing Store files
  • Only use createTestingPinia if you specifically need its testing features
  • Let stores initialize with their natural default state
  • Don't mock the store being tested
  • Ensure Vue reactivity imports are added to store files (computed, ref, watchEffect)
  • Place all mock declarations at the top level
  • Use factory functions for module mocks to avoid hoisting issues
  • Clear mocks between tests to ensure isolation

Development Memories

  • We are using tailwind v4 we do not need a tailwind config anymore
  • always search the internet for tailwind v4 documentation when making tailwind related style changes
