@codervisor/devlog-core

Core functionality for the devlog system. This package provides the main DevlogManager class that handles creation, updating, querying, and management of development logs.

Features

• CRUD Operations: Create, read, update, and delete devlog entries
• Multiple Storage Backends: SQLite, PostgreSQL, MySQL, and Enterprise integrations
• Rich Context: Support for business context, technical context, and AI-enhanced metadata
• Filtering & Search: Query devlogs by status, type, priority, tags, and text search
• Notes & Progress Tracking: Add timestamped notes to track progress
• AI Context Management: Special handling for AI assistant context and insights
• Decision Tracking: Record important decisions with rationale
• Statistics: Get overview statistics of your devlog entries
• Status Workflow: Comprehensive status system for tracking work progression

Devlog Status System

Devlog entries use a well-defined status system to track work progression:

Open Statuses (Active Work):

• new - Work ready to start
• in-progress - Actively being developed
• blocked - Temporarily stopped due to dependencies
• in-review - Awaiting review/approval
• testing - Being validated through testing

Closed Statuses (Completed Work):

• done - Successfully completed
• cancelled - Abandoned/deprioritized

Typical Workflow: new → in-progress → in-review → testing → done

Installation

pnpm add @codervisor/devlog-core

Usage

import { DevlogManager } from '@codervisor/devlog-core';

// Initialize the manager
const devlog = new DevlogManager({
  workspaceRoot: '/path/to/your/project',
  // devlogDir: '/custom/path/.devlog' // optional custom directory
});

// Create a new devlog entry
const entry = await devlog.createDevlog({
  title: 'Implement user authentication',
  type: 'feature',
  description: 'Add JWT-based authentication system',
  priority: 'high',
  businessContext: 'Users need secure login to access protected features',
  technicalContext: 'Using JWT tokens with refresh mechanism',
  acceptanceCriteria: [
    'Users can register with email/password',
    'Users can login and receive JWT token',
    'Protected routes require valid token',
  ],
});

// Update the devlog
await devlog.updateDevlog({
  id: entry.id,
  status: 'in-progress',
  progress: 'Completed user registration endpoint',
});

// Add a note
await devlog.addNote(entry.id, {
  category: 'progress',
  content: 'Fixed validation issues with email format',
});

// List all devlogs
const allDevlogs = await devlog.listDevlogs();

// Filter devlogs
const inProgressTasks = await devlog.listDevlogs({
  status: ['in-progress'],
  type: ['feature', 'bugfix'],
});

// Search devlogs
const authDevlogs = await devlog.searchDevlogs('authentication');

// Get active context for AI assistants
const activeContext = await devlog.getActiveContext(5);

// Complete a devlog
await devlog.completeDevlog(entry.id, 'Authentication system implemented and tested');

API Reference

DevlogManager

Constructor

new DevlogManager(options?: DevlogManagerOptions)

Options:

• workspaceRoot?: string - Root directory of your project (defaults to process.cwd())
• devlogDir?: string - Custom directory for devlog storage (defaults to {workspaceRoot}/.devlog)

Methods

• createDevlog(request: CreateDevlogRequest): Promise<DevlogEntry>
• updateDevlog(request: UpdateDevlogRequest): Promise<DevlogEntry>
• getDevlog(id: string): Promise<DevlogEntry | null>
• listDevlogs(filters?: DevlogFilter): Promise<DevlogEntry[]>
• searchDevlogs(query: string): Promise<DevlogEntry[]>
• addNote(id: string, note: Omit<DevlogNote, "id" | "timestamp">): Promise<DevlogEntry>
• completeDevlog(id: string, summary?: string): Promise<DevlogEntry>
• deleteDevlog(id: string): Promise<void>
• getActiveContext(limit?: number): Promise<DevlogEntry[]>
• updateAIContext(args: AIContextUpdate): Promise<DevlogEntry>
• addDecision(args: DecisionArgs): Promise<DevlogEntry>
• getStats(): Promise<DevlogStats>

Storage

The core package supports multiple storage backends:

• SQLite: Default for local development, provides good performance and full-text search
• PostgreSQL: For production environments requiring multi-user access
• MySQL: Alternative database option for web applications
• Enterprise: Integration with external systems like Jira, Azure DevOps, etc.

Storage is configured through the DevlogManager constructor or environment variables.

Integration

This core package is designed to be used by:

• @codervisor/devlog-mcp - MCP server for AI assistants
• @codervisor/devlog-cli - Command-line interface
• @codervisor/devlog-web - Web interface for browsing devlogs
• Custom applications and scripts
