🔧 Usage

Command Line Interface

The CLI provides the same familiar commands as the original buku:

# Bookmark management
buku add <url> [options]           # Add a new bookmark
buku list [options]                # List bookmarks with pagination
buku search <keywords> [options]   # Search bookmarks
buku delete <ids...> [options]     # Delete bookmarks by ID

# Tag operations
buku tags [options]                # List all tags with counts
buku tag-rename <old> <new>        # Rename tags globally

# Utilities
buku stats                         # Show database statistics
buku export <file> [options]       # Export bookmarks
buku import <file> [options]       # Import bookmarks

Example Workflows:

# Add a bookmark with automatic metadata fetching
buku add https://typescriptlang.org --tags "typescript,docs,programming"

# Search with multiple criteria
buku search "react" --tags frontend,javascript --deep

# Bulk operations
buku delete 1-10 15 20-25          # Delete ranges and individual bookmarks
buku list --tags programming --limit 50 --json > programming-bookmarks.json

REST API Server

Start the high-performance API server:

# Development mode with hot reload
bun run dev

# Production mode
bun run src/server/index.ts

# Custom configuration
PORT=8080 HOST=0.0.0.0 bun run src/server/index.ts

Key Endpoints:

GET    /api/bookmarks              # List bookmarks with pagination
POST   /api/bookmarks              # Create new bookmark
GET    /api/bookmarks/:id          # Get specific bookmark
PUT    /api/bookmarks/:id          # Update bookmark
DELETE /api/bookmarks/:id          # Delete bookmark
POST   /api/bookmarks/search       # Advanced search
GET    /api/tags                   # List all tags with usage counts
GET    /api/stats                  # Database statistics
POST   /api/bookmarks/:id/refresh  # Refresh bookmark metadata

API Example:

# Create a bookmark
curl -X POST http://localhost:5001/api/bookmarks \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "title": "Example Site",
    "tags": "example,demo",
    "desc": "A sample website"
  }'

# Search bookmarks
curl -X POST http://localhost:5001/api/bookmarks/search \
  -H "Content-Type: application/json" \
  -d '{
    "keywords": ["typescript"],
    "tags": ["programming"],
    "deep": true
  }'

Library Integration

Use buku-ts as a TypeScript/JavaScript library:

import { BukuDatabase, BookmarkRepository, BookmarkService } from './src/index.ts';

// Initialize the service
const database = new BukuDatabase({
  dbPath: './my-bookmarks.db'
});
const repository = new BookmarkRepository(database);
const service = new BookmarkService(repository);

// Add bookmarks programmatically
const bookmark = await service.addBookmark({
  url: 'https://example.com',
  title: 'Example Site',
  tags: 'web,demo,example',
  desc: 'A demonstration website'
}, true); // Enable metadata fetching

// Advanced search
const results = await service.searchBookmarks({
  keywords: ['javascript', 'typescript'],
  tags: ['programming', 'web'],
  deep: true,
  all: false  // Match ANY keyword (OR logic)
});

// Tag management
await service.addTagsToBookmark(bookmark.id, ['new-tag', 'updated']);
const tagStats = await service.getAllTags();

// Cleanup
database.close();

🏗️ Architecture

Buku TypeScript follows modern software architecture principles:

┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐
│   CLI Interface │    │   REST API      │    │   Library API   │
│   (Commander)   │    │   (Hono)        │    │   (TypeScript)  │
└─────────┬───────┘    └─────────┬───────┘    └─────────┬───────┘
          │                      │                      │
          └──────────────────────┼──────────────────────┘
                                 │
                    ┌─────────────▼───────────────┐
                    │      Service Layer          │
                    │   (Business Logic)          │
                    └─────────────┬───────────────┘
                                  │
                    ┌─────────────▼───────────────┐
                    │    Repository Layer         │
                    │   (Data Access)             │
                    └─────────────┬───────────────┘
                                  │
                    ┌─────────────▼───────────────┐
                    │     Database Layer          │
                    │   (SQLite + Bun)            │
                    └─────────────────────────────┘

Key Design Patterns:

• Repository Pattern: Clean separation between business logic and data access
• Service Layer: Centralized business rules and validation
• Dependency Injection: Loose coupling and easy testing
• Type-Driven Development: Zod schemas ensure runtime type safety

🧪 Testing

Comprehensive test suite with high coverage:

# Run all tests
bun test

# Run tests with coverage
bun test --coverage

# Run specific test file
bun test tests/bookmark.test.ts

# Watch mode for development
bun test --watch

Test Results:

✓ BookmarkService (10 tests)
✓ TagManager (10 tests)
✓ WebFetcher (5 tests)
✓ Database Operations (8 tests)

33 tests passing, 0 failing
Coverage: 95%+ across all modules

🔄 Migration from Python Buku

Zero-downtime migration - the TypeScript version uses the same database format:

1. Backup your data (recommended):

   cp ~/.local/share/buku/bookmarks.db ~/.local/share/buku/bookmarks.db.backup

2. Install buku-ts (as shown above)

3. Use immediately - all your bookmarks, tags, and metadata are preserved:

   buku list  # Shows all your existing bookmarks
   buku stats # Shows your current statistics

4. Optional: Set custom database path:

   export BUKU_DB_PATH=/path/to/your/bookmarks.db

Migration Benefits:

• ✅ 100% Data Compatibility - Same SQLite schema
• ✅ Preserved Relationships - All bookmark-tag associations maintained
• ✅ Enhanced Performance - Faster queries and operations
• ✅ Modern Features - REST API, better search, type safety
• ✅ Backward Compatibility - Can switch back to Python buku anytime

🔧 Development

Setup Development Environment

# Clone and setup
git clone https://github.com/your-username/buku-ts.git
cd buku-ts
bun install

# Install development tools
mise install  # Installs correct Bun and Node versions

# Install git hooks for code quality
bunx lefthook install

# Run in development mode
bun run dev    # CLI with hot reload
bun run dev:server  # API server with hot reload

Git Hooks

This project uses lefthook for automated code quality checks:

• Pre-commit: Runs lint-staged for optimized file processing and TypeScript type checking
• Commit-msg: Validates commit messages using commitlint with conventional commits format
• Pre-push: Runs full test suite, comprehensive linting, and build verification

The hooks automatically fix formatting issues and stage the fixes, ensuring consistent code quality.

Commit Message Format

This project follows Conventional Commits specification:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Allowed types:

• feat: New feature
• fix: Bug fix
• docs: Documentation changes
• style: Code style changes (formatting, etc.)
• refactor: Code refactoring
• perf: Performance improvements
• test: Test-related changes
• build: Build system changes
• ci: CI/CD changes
• chore: Maintenance tasks
• revert: Revert previous commits

Examples:

feat: add import API endpoints for bookmark management
fix: resolve SQLite connection timeout issues
docs: update API documentation with new endpoints
refactor: extract common validation logic to shared utilities
