Fast Time Logger

Fast Time Logger is a lightweight Azure DevOps work-item tab extension for tracking time with minimal UI latency.

Key features

• Start, pause, resume, and stop timer on a work item
• Manual time entry with optional notes
• Edit and delete entries
• Offline-first local storage with background sync
• Idempotent sync model to avoid duplicate time adds
• Weekly report panel with CSV export

Why it is fast

• Instant first paint with inlined CSS and local-first rendering
• No heavy framework runtime
• Azure DevOps SDK is lazy-loaded after UI is interactive

How it works

• Logs are stored per work item in local storage
• Sync uses operation outbox semantics with retry and dedupe
• Work item total field is updated only on finalized operations

Required work item fields

Configure these custom fields in your process:

• Custom.TimeSpent (Number)
• Custom.TimeLoggerLedger (Plain text or long text)

Usage

1. Open a work item.
2. Go to the Time Logger tab.
3. Track time using timer or manual entry.
4. Review totals and weekly report.
5. Export weekly report as CSV when needed.

Notes

• The extension supports temporary offline usage and syncs when online.
• Weekly report covers the last 7 days ending today.
