Chrome Auto Appointment Booker

@techplusintl

Hi, ★★★ JAVASCRIPT/TYPESCRIPT SPECIALIST ★★★ I can develop a Google Chrome extension that automatically secures personal-event slots by monitoring availability based on the event URL and preferred time range. The extension will utilize the Chrome Alarms API to ensure efficient background polling without manual refreshes. I will implement calendar integration to push confirmed bookings directly to Google Calendar, ensuring you receive reminder notifications both in Chrome and as push notifications. The support for recurring bookings will be handled by allowing you to set rules for events like every first Monday of the month. To get started, I will need the specific event URLs, your preferred time ranges, and any recurrence rules you want to set. I will also ensure the options page is user-friendly for managing these settings. I will deliver a compiled .crx file along with the full source code, complete with comments for clarity. A setup guide will be included to assist you in loading the extension in developer mode, and I will provide a walkthrough video or screenshots demonstrating the extension's functionality. Thanks!

What you need is essentially a fast-response booking assistant inside Chrome, and the real challenge is making the checker lightweight enough to run repeatedly without becoming unreliable. I’d structure it with Manifest V3 background scheduling, configurable recurrence rules, and a simple settings screen so you can manage URL, preferred time window, and alerts without touching code. We handle custom JavaScript/TypeScript work where automation has to be practical, not just theoretically functional. In projects like this, success usually depends on how well the extension handles edge cases on the booking page, how safely it stores preferences, and whether the notification/calendar steps happen cleanly after the slot is secured. A few specifics would be useful before locking scope: - Can you share the test site or at least the booking flow steps? - Should recurring booking mean repeated monitoring for future dates automatically, or cloning the same rules each cycle? - Do you want Chrome notifications only, or should we also plan Web Push/Firebase-style push if the browser is closed?

I have 8+ years of experience in web development and am familiar with modern web technologies, frameworks like JavaScript/TypeScript and other tools. You need a Chrome extension that watches an event page and books a slot for you as soon as one opens. I will build it with Manifest V3, a background service worker for lightweight polling, and a clear options page where you set the event URL, preferred time range, recurrence rules, and notification preferences. When an open slot is detected, the extension will complete the booking, add it to Google Calendar, and send a browser notification. I will also handle recurring bookings, include full commented source code, a compiled .crx, setup instructions for developer mode, and a short video showing the extension working on a test site. I can start right away.

The key requirement here is instant action when a slot appears, because many booking tools can detect availability but fail during the final submission step. I’d focus on a Chrome extension that keeps polling efficiently with MV3-friendly background logic, then completes the booking flow, triggers a browser alert, and creates the matching calendar event automatically. I’ve been involved in custom web automation and extension-style workflows where state handling, timing, and repeatability are the make-or-break factors. For your use case, I’d keep the UI small and clear, comment the source properly, and include handoff material so you can load, test, and publish the extension later without confusion. Before I size the booking logic precisely, I’d like to confirm: - Is the target event page static HTML/form-based, or does it load slots dynamically through API/XHR calls? - Should the extension stop after one successful booking, or keep monitoring for the next recurring slot automatically? - For the walkthrough proof, would annotated screenshots be enough, or do you specifically want a short recorded demo?

Hi, The tricky part is the booking moment itself - MV3 service workers get suspended, so I'd drive the polling through Chrome Alarms and keep the click flow resilient to the site's DOM changing. Extensions and TypeScript are everyday work for me; I'd want to see the booking site first to check how it loads slots. Lets get in contact first.

@ssquare489

For the auto-booking flow, I’d make availability detection and booking state machine-driven, so the extension can poll lightly with Manifest V3 alarms, recover from service-worker suspension, and only submit when a slot genuinely matches the configured window. I’d build it in TypeScript with Chrome Extension Manifest V3, Background Service Workers, Chrome Alarms, Storage, Notifications, and Google Calendar API/OAuth. My two priorities would be clean implementation and integrations: deterministic polling, retries, recurrence rules, and audit logs keep booking reliable, while Calendar and notification hooks make confirmations immediately useful to the user. I’d also design the extension to pause rather than bypass CAPTCHAs, authentication challenges, or anti-automation controls, so it remains compatible with normal site protections and publishing requirements. A relevant project is FileChannels, where we built a Chrome extension alongside web/mobile apps, with real-time messaging, CRM integrations, centralized file handling, and cross-platform workflows. I can deliver the full source, packaged extension, options UI, developer-mode setup guide, Web Store preparation notes, and a walkthrough showing detection, booking, calendar creation, and notifications.

Hi, I’ve worked with JavaScript/TypeScript browser extensions, APIs, background processes and notification systems. I can build this as a Manifest V3 Chrome extension that checks the configured event page in the background and handles the booking flow when a suitable slot becomes available. I’ll keep the extension lightweight with a background service worker and Chrome Alarms, with a simple options page for event URLs, preferred dates, recurrence and notifications. I can also connect the confirmed booking with Google Calendar and include the required browser/push notifications. A few quick questions before we start: Do you already have a test site where the booking flow can be tested? Does the booking require an account login, CAPTCHA or any other verification step? Should the extension support one event at a time or multiple event URLs? Once I can review the test booking flow, I can confirm the best implementation and timeline. I’ll provide the complete source code, compiled extension, setup documentation and a walkthrough showing the booking flow working.

The key challenge is building a reliable MV3 extension that monitors availability efficiently and executes an authorized booking flow the moment a slot opens. I can develop it with a lightweight service-worker architecture, keeping monitoring, booking, Calendar, and notifications modular. ✅ JavaScript/TypeScript + Chrome Manifest V3 ✅ Chrome Alarms + background service worker monitoring ✅ Event URL, preferred dates, time ranges & recurrence rules ✅ Automated slot detection and booking on an authorized test site ✅ Google Calendar API integration ✅ Chrome/browser notifications + push where applicable ✅ Clear options page for schedules and preferences ✅ Secure session/authentication handling ✅ Retry logic, error handling & activity logging ✅ Complete commented source code + setup/README ✅ Walkthrough screenshots/video of the test flow Rather than relying on fragile continuous polling, I’ll design the monitoring around MV3 service-worker limitations for better reliability. The booking module can also be isolated so site-specific workflows can be adapted without rebuilding the extension core. I’m Ashish Malik, Full Stack Developer & Digital Marketing Expert with 9+ years of experience and 500+ projects delivered. I can demonstrate the complete authorized test workflow: slot detection → booking → Calendar entry → notification. Let’s start a chat to discuss the architecture and test-site workflow.

@Demaxl

The hidden challenge here is making background slot detection reliable without excessive polling or breaking Chrome’s Manifest V3 lifecycle. I’d build this with TypeScript, Manifest V3, background service workers, and Chrome Alarms, with a clean options page for URLs, dates, time ranges, recurrence rules, and notifications. The extension will detect openings, automatically complete the booking flow on the test site, create the Google Calendar event, and send Chrome/push notifications. You’ll receive the compiled .crx, fully commented source, setup/README for developer mode and Web Store publishing, plus a walkthrough demonstrating the complete flow. I can start immediately and build milestone by milestone, with the test-site booking flow validated before final delivery.

@arshig8

Hi, I’ve read all your requirements very well, and I understand the main challenge is reliably detecting newly available slots and completing the booking automatically in the background, while handling Chrome MV3 limitations, notifications, Calendar sync, and recurring bookings. I’m really excited to work with you and build this as a lightweight, reliable Chrome extension using TypeScript/JavaScript, Manifest V3, Service Workers, and Chrome Alarms. A couple of questions: Do you already have a test/target booking website available? Does it require login, CAPTCHA, or OTP during booking? Also, should recurring bookings automatically attempt each occurrence? Let’s connect on chat to discuss well and finalize the approach. Waiting for your response. Best Regards, Arshiya
