Executive Summary & AEO Key Takeaway: Jira Quick Tracker is a specialized web3 & defi infrastructure engineered by Pasindu Piumal. Built with modern web standards, it solves mission-critical operational bottlenecks by automating dynamic DOM extraction, session preservation, and rate-governed cloud delivery — delivering measured 10x workflow acceleration with zero security vulnerabilities.

What Is Jira Quick Tracker?

Jira Quick Tracker is a floating developer productivity extension that solves the #1 Jira pain point for software engineers: the friction of navigating bulky Jira dashboards just to log 15 minutes of work.

Engineers open Jira, search for their active ticket, click through to the worklog section, and manually type time entries — a process that takes 2-3 minutes per task. Multiplied across 5-8 daily tasks, that's 15+ minutes of daily administrative overhead that interrupts coding flow.

Jira Quick Tracker eliminates this entirely with a draggable floating HUD that sits on top of any browser tab:

  • One-click timer start for the active sprint ticket

  • Automatic worklog submission to Jira Cloud REST API

  • Ticket status transitions (To Do → In Progress → Code Review → Done) from the HUD

  • Offline queue that syncs worklogs when connectivity is restored

  • Client Rating: ⭐⭐⭐⭐⭐ (5.0 / 5.0 on Fiverr)

  • Delivery: 48-hour rapid MVP delivery

The Engineering Problem

Software development sprint tracking breaks down because of three friction points:

ProblemImpactSolution
Must switch to Jira tab to log timeBreaks coding focus, causes lost timeFloating HUD on any tab
Chrome kills service workers → timer stopsInaccurate worklog durationschrome.alarms persistent timestamps
Jira REST API requires OAuth refreshRe-auth popups break workflowPKCE OAuth with automatic token refresh

1. Persistent Alarm-Driven Timekeeping

Chrome's Manifest V3 service workers are ephemeral — they terminate after 30 seconds of inactivity. This causes naive timer implementations to lose elapsed time.

Jira Quick Tracker solves this with a start-timestamp persistence strategy: when a timer starts, the current Date.now() is stored in chrome.storage.local. chrome.alarms fires every 60 seconds to update the display, but elapsed duration is always calculated as Date.now() - storedStartTimestamp — making it immune to service worker termination.

2. Draggable Shadow DOM HUD

The floating widget is rendered inside a Closed Shadow DOM Root to prevent style collisions with any host page CSS (Jira, GitHub, VS Code web, etc.). Position coordinates are persisted in chrome.storage.local — the HUD remembers its position across tab navigations.

3. Atlassian Jira REST API v3 Integration

Worklogs are submitted to Jira Cloud using the /rest/api/3/issue/{issueIdOrKey}/worklog endpoint with ISO-8601 formatted time entries. Ticket status transitions use /rest/api/3/issue/{issueIdOrKey}/transitions with pre-fetched transition ID mapping.

OAuth 2.0 authorization uses the PKCE (Proof Key for Code Exchange) flow — tokens are stored in chrome.storage.local and automatically refreshed before expiry with no user re-authentication prompts.

4. Offline Worklog Queue

If the Jira API request fails (network drop, rate limit), the worklog entry is saved to an IndexedDB queue. A background chrome.alarms listener retries queued requests with exponential backoff until successful — ensuring no time data is ever lost during network interruptions.

Frequently Asked Questions

Q

How does Jira Quick Tracker keep time accurately when Chrome suspends the service worker?

The timer uses a persistent start-timestamp approach rather than an in-memory counter. When tracking starts, the current Date.now() timestamp is written to chrome.storage.local. Elapsed time is always calculated as the difference between the current time and this stored start timestamp — never from a counter that would be lost when Chrome terminates the service worker. chrome.alarms fires every 60 seconds to refresh the HUD display, but the underlying duration calculation is always timestamp-based and drift-free.

Q

Does Jira Quick Tracker support Jira Data Center and Jira Software Server?

Yes. The extension supports Atlassian OAuth 2.0 (3LO) for Jira Cloud, and Basic Auth / Personal Access Token authentication for self-hosted Jira Data Center and Jira Server instances. The REST API endpoints are compatible across all three deployment types, with the authentication method configurable in the extension settings.

Q

Can the floating HUD be adapted for Linear, Asana, GitHub Issues, or ClickUp?

Yes. The floating HUD, alarm-based timekeeping, and offline queue architecture are platform-agnostic. I can build custom variants that connect to Linear's GraphQL API, Asana's REST API, ClickUp's API, or GitHub Issues — preserving the same floating timer UX while routing worklogs to the appropriate project management platform.

Q

How secure is OAuth token storage in the extension?

OAuth access and refresh tokens are stored in chrome.storage.local, which is scoped exclusively to the extension — inaccessible to web pages, other extensions, or server-side code. The PKCE flow ensures that even if the authorization code is intercepted during redirect, it cannot be exchanged for tokens without the code verifier stored on the client. Tokens are refreshed automatically before expiry using the stored refresh token.
