Node.js Express Error Capture: Request Context for Logistics Cost Tracking

A useful error record for a logistics agent must connect the failure to one shipment, one request, and the work already consumed by the agent loop. Capture request context and cumulative usage at the same boundary that records the stack trace. Otherwise, a rejected model call may be visible while the latency and token spend that preceded it disappear into aggregate charts. The implementation below uses Express, AsyncLocalStorage , and a small structured event sink; it keeps the transport repl...

Promotion - Canary Deployment

a small, yellow songbird. a small yellow bird that sings and is often kept as a pet. What is Canary Deployment ? Its a technique for rolling out new features or changes to a small traffic or instance before releasing the update to the entire system. A small percentage of traffic is then routed to the new deployment , while the majority of the traffic continues to be served by the original deployment. If the issues are detected during the canary deployment , it can be qu...

5 Node.js Email Deliverability Controls — Product Event Notifications Setup That Survives

TL;DR: Treat every contact-form notification as an auditable state machine, not a successful API call. Verify a DKIM-aligned sending domain, consult a regional suppression set before enqueueing, assign an idempotency key, and poll the delivery interface until each attempt reaches a terminal state. For a healthtech support router, that evidence is what separates "accepted" from "handled." The storage bill is driven less by the contact form itself than by retained delivery evidence: status snap...

How to read a Steam player count (and tell if a game is actually dying)

I spent 30 days watching one Steam game's player count every morning before anything else. Here's the method I ended up with, so you can read any game yourself instead of guessing. 1. Use two clocks. steamcharts lags the official Steam number by 1-3 hours. When they disagree hard, one is stale, and the Steam Community hub's live count settles which. 2. Read the trough, not the peak. The low point (roughly 03:00-07:30 UTC) is the floor: who's still there when it's 4am somewhere and nobo...

Google Hotels prices per booking site (and a 90-day price calendar) as JSON

Disclosure: I build the Apify Actor used in this post (TubeText Labs). Google Hotels shows, for every hotel, what each booking site charges for your dates – Booking.com, Expedia, Hotels.com, the hotel's own site and many smaller agencies. There is no public API for those prices (Google's Hotel Prices API is for partners sending prices in , not for reading them). Here's how to get them as JSON, plus a 90-day price calendar for a single hotel. 1. Every hotel in a city, with prices...
