Epoch

Epoch is a modern, terminal-based task logger and time tracker built with TypeScript, React, and Ink. It features a three-pane layout designed for efficiency and keyboard-centric workflows, allowing you to manage nested tasks and track your time without ever leaving the terminal.

Features

• Three-Pane Layout: Seamlessly switch between Calendar, Tasks, and Timeline views.
• Calendar View: Navigate through months and days to visualize task distribution and select specific dates.
• Infinite Nesting: Break down complex projects with support for infinitely nested subtasks.
• Activity Timeline: Automatically logs every action (start, complete, delegate) with precise timestamps.
• Task States: Track tasks through 'todo', 'completed', 'delegated', and 'delayed' states.
• Extensible Themes: Comes with built-in dark and light themes (plus 20+ community themes like Catppuccin, Nord, Dracula).
• Local Persistence: Data is saved locally in JSON format for easy backup, portability, and privacy.
• Cross-Machine Sync: Export and import your data across machines using temporary cloud storage with secure 8-character codes.

Installation & Running

• e: Edit task title
• d: Delete task
• Space: Toggle completion status
• s: Start task (sets start time)
• D: Mark as delegated
• x: Mark as delayed/cancelled

• Enter: Expand/Collapse subtasks

Timeline Pane

• j / k: Scroll through activity history

Data Storage

Your data is stored locally in a human-readable JSON file. This allows for easy backups or manual editing if necessary.

• macOS: ~/Library/Application Support/epoch/data.json
• Linux: ~/.local/share/epoch/data.json (or $XDG_DATA_HOME)
• Windows: %APPDATA%\epoch\data.json

Cross-Machine Data Sharing

Epoch now supports exporting and importing your data across machines using a temporary cloud-based storage solution. This feature is perfect for syncing your tasks between your work laptop and home desktop, or sharing a snapshot with a colleague.

How It Works

The sharing functionality uses a dedicated server (see server/ directory) that:

• Temporarily stores your data in Redis (Upstash)
• Generates a secure 8-character code for each export
• Expires data after 5 minutes (TTL: 300 seconds)
• Hashes codes with bcrypt for security
• Rate limits requests (100 requests per 15 minutes)

Usage

Exporting Data

epoch export

This will:

1. Upload your current data to the server
2. Generate a unique 8-character code
3. Display the code and expiration time

Example output:

Data exported successfully!
---------------------------
Secret Key: aB3dE7fG
Expires: 1/4/2026, 7:45:30 PM
---------------------------

Run 'epoch import' on another machine and enter this key to sync your data.

Importing Data

epoch import

This will:

1. Prompt you to enter the 8-character code
2. Fetch the data from the server
3. Ask whether to replace or merge with existing data
4. Replace (r): Overwrites all local data
5. Merge (m): Combines remote data with local, preserving both

Example workflow:

$ epoch import
Enter your secret key: aB3dE7fG

Data found! Do you want to (r)eplace existing data or (m)erge with it? [r/m]: m
Data successfully merged.

Server Details

The export/import server is hosted at https://epoch-server.actuallyakshat.in and provides:

• Health check endpoint: GET /api/health
• Export endpoint: POST /api/data/export
• Import endpoint: POST /api/data/import

For development or self-hosting, see the server/ directory for complete setup instructions including:

• Express.js + TypeScript server
• Upstash Redis integration
• Docker deployment configuration
• Swagger API documentation

Note: Data is stored temporarily (5 minutes) for security and privacy. This is not a backup solution—it's designed for quick transfers between machines.

Tech Stack

• UI Framework: React + Ink
• Language: TypeScript
• State Management: React Context
• Date Handling: date-fns
• Persistence: File System (JSON)

Development & Code Quality

Testing

pnpm test          # Run tests
pnpm test:coverage # Run tests with coverage report

Code Formatting

Code is automatically formatted with Prettier on every commit.

pnpm format        # Format all files
pnpm format:check  # Check formatting without modifying files

Local SonarQube Analysis

This project uses SonarQube for local code quality analysis (runs in pre-commit hook).

To run SonarQube locally:

# Start SonarQube server (Docker)
docker run -d -p 9000:9000 --name sonarqube sonarqube

# Initialize server at http://localhost:9000 (admin/admin)
# Create a new project and generate a token

# Add token to environment
export SONAR_TOKEN=your_token_here

# Run analysis
pnpm sonar

Pre-commit Hook:

• Runs lint-staged to format staged files with Prettier
• Attempts to run SonarQube scanner (non-blocking if server unavailable)

Configuration: See sonar-project.properties
