Da CLI Deviantart Sync

da-cli DeviantArt Sync Skill

Skill by ara.so — Devtools Skills collection.

Overview

da-cli is a zero-dependency Python CLI tool that syncs DeviantArt galleries to local folders. It uses OAuth 2.1 with PKCE for authentication, maintains a SQLite index for incremental syncs, and supports scheduled backups via launchd (macOS) or systemd (Linux). Key features:

• Zero runtime dependencies — pure Python 3.10+ stdlib
• Incremental sync — SQLite index tracks what's downloaded; re-runs cost one API call when nothing's new
• OAuth 2.1 PKCE — secure authentication with automatic token refresh
• Multiple sync modes — watch feed, specific artists, all watched users
• Scheduled automation — launchd/systemd integration for unattended syncs
• Search & browse — tags, topics, daily deviations, user profiles
• Secrets in Keychain — macOS Keychain integration for client secrets

Installation

Option A: pipx (recommended)

# Install with isolated environment
pipx install da-sync

# Verify installation
da --version

Option B: git clone (for development)

# Clone repository
git clone https://github.com/FZ2000/da-cli.git ~/Documents/da-cli
cd ~/Documents/da-cli

# Install shim (creates ~/.local/bin/da)
./install.sh

# Verify
da --version

Requirements: Python 3.10+ (uses argparse.BooleanOptionalAction and X | None syntax)

Initial Setup

1. Create DeviantArt OAuth App

# Navigate to DeviantArt developers portal
# https://www.deviantart.com/developers/
# Click "Register Your Application"
# Set these values:
#   - Application Type: Confidential
#   - Redirect URI Whitelist: https://localhost:8765/ (exact, with trailing slash)
# Save your client_id and client_secret

2. Configure da-cli

# Set client credentials (secret goes to Keychain on macOS)
da config set client_id YOUR_CLIENT_ID
da config set client_secret YOUR_CLIENT_SECRET

# Set download destination
da config set destination ~/Pictures/DA

# Optional: customize scope (defaults to browse+collection+user)
da config set scope "browse collection user"

# View current configuration
da config show

3. Authenticate

# Start OAuth flow (opens browser)
da auth

# Verify authentication
da whoami

# Check token status
da refresh

Core Commands

Authentication

# Initial login (browser-based PKCE flow)
da auth

Configuration Reference

Config File Locations

# Config file (settings)
~/.config/da-cli/config.json

# State file (tokens)
~/.local/state/da-cli/state.json

# Sync index (SQLite)
~/.local/state/da-cli/sync.db

# Logs
~/.local/state/da-cli/sync.log

Key Settings

{
  "client_id": "12345",
  "destination": "/Users/username/Pictures/DA",
  "scope": "browse collection user",
  "mature_content": true,
  "sleep_between_requests": 1.0,
  "max_retries": 3,
  "checkpoint_interval": 50,
  "default_limit": 24
}

Environment Variables

# Override config location
export DA_CLI_CONFIG_DIR=~/custom/config/path

# Override state location
export DA_CLI_STATE_DIR=~/custom/state/path

# Set client credentials (alternative to config file)
export DA_CLIENT_ID=your_client_id
export DA_CLIENT_SECRET=your_client_secret

# Set destination
export DA_DESTINATION=~/Pictures/DA

Common Patterns

Initial Full Sync of Watched Artists

# First, sync watch feed to discover artists
da sync feed --limit 500

# Then backfill each artist's full gallery
da sync watched

# Or do it individually
da sync artist artist1
da sync artist artist2

Sync with Rate Limiting

# Add random jitter to avoid detection
da sync feed --jitter 0.5

# Increase sleep between requests
da config set sleep_between_requests 2.0
da sync feed

# Limit total sync time
da sync feed --max-minutes 15

Filter Content

# Exclude mature content
da sync feed --no-mature

# Sync only mature content (edit directly)
# In sync flow, filter is applied to API params

Resume Interrupted Sync

# Sync automatically resumes from last checkpoint
# Checkpoint is saved every 50 deviations (configurable)
da sync feed

# View checkpoint
da index show | grep checkpoint

# Force fresh start (clear checkpoint)
da index rebuild

Troubleshooting

Redirect URI Mismatch

# Error: redirect_uri does not match
# Solution: Ensure OAuth app has EXACT redirect URI
# https://localhost:8765/ (with trailing slash)

# Verify in config
da config get redirect_uri
# Should show: https://localhost:8765/

Expired Refresh Token

# Tokens expire after 90 days
# Check token status
da diagnose

# Re-authenticate
da auth logout
da auth

Scheduled Job Not Running

# Check job status
da diagnose

# macOS: verify launchd
launchctl list | grep da-sync
launchctl start com.user.da-sync  # test immediately

# Linux: verify systemd
systemctl --user status da-sync.timer
systemctl --user status da-sync.service
journalctl --user -u da-sync.service

Permission Denied on macOS

# Grant Full Disk Access to Terminal/iTerm
# System Preferences → Privacy & Security → Full Disk Access
# Add Terminal.app or iTerm.app
# Restart Terminal

# Verify permissions
ls -la ~/.local/state/da-cli/

Missing Dependencies (dev)

# If running from git clone
cd ~/Documents/da-cli
make dev-setup  # installs dev dependencies (ruff, mypy, pytest)

Keychain Access Issues

# If Keychain denies access
# Run once to trigger permission prompt
da config set client_secret YOUR_SECRET

# If still blocked, manually allow in Keychain Access.app
# Find "da-cli" items and set access to "Always Allow"

Index Corruption

# Rebuild index from destination folder
da index rebuild

# Check index integrity
sqlite3 ~/.local/state/da-cli/sync.db "PRAGMA integrity_check;"

API Scope Reference

# browse: search, topics, daily deviations, public galleries
# collection: sync your own collections/favorites
# user: watch list, user profile

# Default (recommended)
da config set scope "browse collection user"

# Minimal (read-only search/browse)
da config set scope "browse"

# Full access (includes messaging, stash - not used by da-cli)
da config set scope "browse collection user message stash"

Best Practices

1. Use pipx for installation — keeps da-cli isolated from system Python
2. Store secrets in Keychain — never commit config.json with secrets
3. Enable jitter for large syncs — --jitter 0.4 randomizes request timing
4. Run da diagnose before troubleshooting — checks all common issues
5. Schedule syncs during off-hours — reduces API load and bandwidth usage
6. Use --via-feed for watched sync — works without user scope
7. Set checkpoint interval — da config set checkpoint_interval 100 for long syncs
8. Monitor logs — tail -f ~/.local/state/da-cli/sync.log

Security Notes

• Client secret: stored in macOS Keychain (service: da-cli, account: client_secret)
• Tokens: stored in ~/.local/state/da-cli/state.json with 0600 permissions
• PKCE mandatory: code_verifier generated per-auth, never leaves machine
• No telemetry: zero network calls except to DeviantArt API and image CDNs
• All HTTPS: API and image downloads are TLS-encrypted
• .gitignore included: secrets-bearing files cannot be accidentally committed
