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

Project Overview

Spoolman is a self-hosted web service for managing 3D printer filament spools. It tracks inventory, monitors usage, and integrates with OctoPrint and Klipper/Moonraker.

Tech Stack:

• Backend: Python 3.9-3.12, FastAPI, SQLAlchemy 2.0 (async), Alembic
• Frontend: React 19, TypeScript, Vite, Ant Design, Refine framework
• Databases: SQLite (default), PostgreSQL, MySQL, CockroachDB

Common Commands

Python (PDM)

pdm install                    # Install all dependencies including dev
pdm sync --prod --no-editable  # Install production dependencies only
pdm run app                    # Run backend server (uvicorn)
pdm run itest                  # Run integration tests (all databases)
pdm run docs                   # Generate API documentation

Frontend

cd client
npm ci                         # Install dependencies
npm run dev                    # Development server with hot reload
npm run build                  # Production build
npm run tsc                    # Type check only

Linting/Formatting

black .                        # Format Python code
ruff check . --fix             # Lint and auto-fix Python
pre-commit run --all-files     # Run all pre-commit hooks

Integration Tests

Tests run in Docker containers against multiple database types:

python tests_integration/run.py sqlite          # Single database
python tests_integration/run.py sqlite postgres # Multiple databases
pdm run itest                                   # All databases

Run a single test:

pytest tests_integration/tests/spool/test_add.py::test_add_spool_remaining_weight -v

Database Migrations

1. Edit models in spoolman/database/models.py
2. Run the server to update local SQLite
3. pdm run alembic revision -m "description" --autogenerate
4. Review generated migration, format with Black/Ruff

Architecture

Backend (/spoolman/)

• main.py - FastAPI app entry, startup/shutdown, SPA mounting
• env.py - Environment variable parsing and configuration
• ws.py - WebSocket manager for real-time updates
• api/v1/ - REST endpoints and WebSocket handlers
  • router.py - Main router with WebSocket root endpoint
  • spool.py, filament.py, vendor.py - CRUD endpoints per resource
  • models.py - Pydantic response models
• database/ - SQLAlchemy models and async database operations
  • models.py - ORM definitions (Vendor, Filament, Spool, Setting, *Field)
  • database.py - Connection setup, backup logic, migrations

Frontend (/client/src/)

• App.tsx - Routing and Refine framework setup
• pages/ - Page components (spools/, filaments/, vendors/, settings/)
• components/dataProvider.ts - REST API integration
• components/liveProvider.ts - WebSocket live updates

Data Model

Vendor (1) ──→ (many) Filament (1) ──→ (many) Spool

All entities support custom fields via *Field tables (VendorField, FilamentField, SpoolField).

API Patterns

• REST: Standard CRUD at /api/v1/{resource}
• WebSocket: Real-time events at WS /api/v1/ or WS /api/v1/{resource}
• Query params: ?skip=0&limit=50&sort_by=name&sort_order=asc

Key Configuration

Environment variables (see .env.example):

• SPOOLMAN_DB_TYPE - Database type (sqlite/mysql/postgres/cockroachdb)
• SPOOLMAN_PORT - Server port (default: 7912)
• SPOOLMAN_DEBUG_MODE - Enables permissive CORS
• VITE_APIURL - Frontend API base URL (e.g., /api/v1)

Code Quality

• Line length: 120 characters
• Python target: 3.9
• Pre-commit hooks enforce Black formatting and Ruff linting
• Backend is fully async using SQLAlchemy AsyncSession

Issue #1 Complete - Inline Creation Modals

Added ability to create filament/vendor inline without leaving the page:

• client/src/components/vendorCreateModal.tsx - Quick vendor creation
• client/src/components/filamentCreateModal.tsx - Quick filament creation with nested vendor modal
• Modified spool create to add "Create Filament" in dropdown
• Modified filament create to add "Create Manufacturer" in dropdown
• Uses dropdownRender pattern (same as location select)
• Uses useInvalidate to refresh lists after creation

Issue #2 Complete - Smart Density Defaults

Auto-fill density based on material type:

• client/src/utils/materialDefaults.ts - Density lookup table with fuzzy matching
• Material field converted to AutoComplete (dropdown suggestions + free text)
• Fuzzy matching: "PLA Silk" → PLA (1.24 g/cm³)
• New filaments default to 1.75mm diameter and 1.24 g/cm³ (PLA)
• Applied to both full create page and FilamentCreateModal
• Edit page not affected (preserves user customizations)

Material densities in lookup:

PLA: 1.24, ABS: 1.04, PETG: 1.27, NYLON: 1.52, TPU: 1.21
PC: 1.3, WOOD: 1.28, CF: 1.3, PC/ABS: 1.19, HIPS: 1.03
PVA: 1.23, ASA: 1.05, PP: 0.9, POM: 1.4, PMMA: 1.18, FPE: 2.16

Issue #3 Complete - QR Code Sizing Fixes

See upstream issue: https://github.com/Donkie/Spoolman/issues/671

Changes:

• Removed fixed 50% max-width constraint (now uses fit-content by default)
• Added qrCodePadding setting (0-10mm, default 2mm)
• Added qrCodeMaxWidth setting (0-100%, 0 = auto)
• Added UI controls with slider + input number for both settings

Files modified:

• client/src/pages/printing/printing.tsx - Added settings to interface
• client/src/pages/printing/qrCodePrintingDialog.tsx - CSS and UI controls

Issue #4 Complete - Layout Max-Width

Changes:

• Added 1400px max-width container in SpoolmanLayout
• Added 800px max-width for forms via CSS override in overrides.css
• Content is centered on wide screens

Issue #5 Complete - Temperature Ranges

Store extruder and bed temperatures as min/max ranges:

• Added 4 new DB columns: settings_extruder_temp_min/max, settings_bed_temp_min/max
• Old single-value columns kept for backward compatibility (deprecated)
• Alembic migration copies existing values to both min and max
• Frontend uses Space.Compact with min/max input pairs
• Label template shows ranges: "ET: 190-220 °C"

Files:

• spoolman/database/models.py - New columns
• migrations/versions/2025_01_15_0200-*.py - Migration
• spoolman/api/v1/models.py, filament.py - API changes
• client/src/pages/filaments/create.tsx - Form updates
• client/src/pages/printing/spoolQrCodePrintingDialog.tsx - Template tags

Issue #6 Complete - Spool Adjustment History

Track history of all spool weight/length adjustments with timestamps and comments.

Backend:

• spoolman/database/models.py - Added SpoolAdjustment model with relationship to Spool
• migrations/versions/2025_01_15_0300-*.py - Migration for spool_adjustment table
• spoolman/api/v1/models.py - Added SpoolAdjustment Pydantic model
• spoolman/api/v1/spool.py - Added comment field to use/measure endpoints, GET /spool/{id}/adjustments endpoint
• spoolman/database/spool.py - Updated use_weight, use_length, measure functions to record adjustments

Frontend:

• client/src/pages/spools/model.tsx - Added ISpoolAdjustment interface
• client/src/pages/spools/show.tsx - Collapsible adjustment history table
• client/public/locales/en/common.json - Translation keys for history table

Issue #7 REMOVED - 3dfilamentprofiles Integration

Removed - 3dfilamentprofiles.com has Vercel bot protection blocking automated requests. Their GitHub repo only has sample data (~3 filaments). SpoolmanDB has 6,957+ filaments, so this was unnecessary.

Issue #10 Complete - Database Import/Export

Full backup/restore functionality for migrating between databases (PostgreSQL ↔ SQLite).

Backend (spoolman/api/v1/backup.py):

• GET /api/v1/backup/export - Downloads all data as single JSON file
• POST /api/v1/backup/import - Imports JSON with replace option
• Exports: vendors, filaments, spools, spool_adjustments, settings
• Handles ID remapping to maintain relationships
• Requires python-multipart package for file uploads

Frontend (client/src/pages/settings/generalSettings.tsx):

• "Backup & Restore" section in Settings page
• "Download Backup" button for export
• File upload with "Import (Merge)" or "Import (Replace All)" options
• Confirmation dialog for destructive replace operation

Migration workflow:

1. Export from PostgreSQL instance via Settings → Download Backup
2. Reconfigure container for SQLite
3. Import via Settings → Import (Replace All)

To run locally against the Unraid PostgreSQL database:

# Create virtualenv and install deps
python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[postgres]"

# Start backend (reads .env file)
source .venv/bin/activate
export $(grep -v '^#' .env | xargs)
uvicorn spoolman.main:app --host 0.0.0.0 --port 7912

# Start frontend (separate terminal)
cd client
VITE_APIURL=http://localhost:7912/api/v1 npm run dev

Access at http://localhost:5173

Issue #11 Complete - Theme Colors

Added theme color selector with 5 color options:

• client/src/contexts/color-mode/index.tsx - Theme color system with THEME_COLORS constant
• Colors: orange, teal, red, green, blue
• Persists in localStorage
• Settings page has color selector buttons

Issue #12 Complete - Clickable Dashboard Cards

Dashboard cards now link to their respective list pages:

• client/src/pages/home/index.tsx - Card body is clickable, links to list
• Only the + button stays independent (for create)

Issue #13 Complete - QR Code Size Setting

Added explicit QR code size control:

• client/src/pages/printing/printing.tsx - Added qrCodeSize to interface
• client/src/pages/printing/qrCodePrintingDialog.tsx - Slider for size in mm (0=auto)

Issue #15 Complete - Print Job Tracking / Slicer Integration

Track pending print jobs from slicer and manage filament deduction after prints complete.

Workflow:

1. Slicer post-processing script parses G-code for filament usage
2. Script creates pending print job in Spoolman via API
3. After print completes, user visits Print Queue UI
4. Complete: Deducts filament from spool, records adjustment history
5. Cancel: Flags spool for manual weigh-in (no automatic deduction)

Backend:

• spoolman/database/models.py - PrintJob model, needs_weighing field on Spool
• spoolman/database/print_job.py - CRUD operations for print jobs
• spoolman/api/v1/print_job.py - REST API endpoints
  • POST /print-job - Create pending job
  • POST /print-job/{id}/complete - Complete job, deduct filament
  • POST /print-job/{id}/cancel - Cancel job, flag spool for weighing
  • GET /print-job - List jobs with status filter
• migrations/versions/2025_01_15_0400-c3d4e5f6g7h8_add_print_jobs.py

Frontend:

• client/src/pages/print-queue/index.tsx - Print Queue UI page
• client/src/pages/spools/model.tsx - IPrintJob interface, needs_weighing on ISpool

Slicer Script:

• scripts/slicer_post_process.py - Elegoo/Orca Slicer post-processing script
• Parses G-code comments for filament usage (weight in grams)
• Creates pending print job via API
• Configure via env vars: SPOOLMAN_URL, SPOOLMAN_SPOOL_ID
• Or config file: ~/.config/spoolman/slicer.conf

Color Column in Spool List

Added optional color column to the spool list with filtering capability.

Backend:

• spoolman/database/filament.py - find_colors() function to get distinct color hex codes
• spoolman/api/v1/other.py - GET /api/v1/color endpoint to list all colors
• spoolman/api/v1/spool.py - Added filament.color_hex query parameter for filtering
• spoolman/database/spool.py - Filter implementation (supports comma-separated values)

Frontend:

• client/src/components/column.tsx - ColorFilterColumn component renders color swatches
• client/src/components/otherModels.tsx - useSpoolmanColors() hook to fetch colors
• client/src/pages/spools/list.tsx - Added color column (hidden by default)
• client/public/locales/en/common.json - Added "Color" translation key

Features:

• Color displayed as small swatch with hex tooltip
• Filter dropdown shows swatches with hex codes
• Multi-select filtering (can filter by multiple colors)
• Column hidden by default (enable via column selector)

Known Issues / TODO

Parse Temperature from Comments

Some filaments have temp info in comment field (e.g., "extrude 190-230 / bed 50-70") but not in the min/max fields. Could add a migration or button to parse and populate.

Filament Select Not Refreshing After Inline Creation

When creating a filament via the inline modal on spool create page, the select dropdown doesn't immediately show the new filament with its name (shows ID instead).

Issue #7 - 3dfilamentprofiles Integration REMOVED

The 3dfilamentprofiles.com website has Vercel bot protection that blocks automated requests. Their GitHub repo (jklewa/filament-profiles-data) only provides sample data (~3 filaments). Since SpoolmanDB already has 6,957+ filaments from major brands, the 3dfp integration was removed rather than maintaining dead code.

Future: Issue #9 - Hierarchical Locations

Add room/bin/shelf support for locations. See Gitea issue #9 for details.
