Use when setting up a new project's production observability stack, reviewing incident response readiness, or investigating why errors are going undetected.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Integrate real-time error monitoring in production

Production errors are invisible without monitoring. Users rarely file detailed bug reports — they simply leave. Error monitoring gives you actionable stack traces, breadcrumbs, and user context within seconds of an issue occurring, cutting mean time to detect (MTTD) from days to minutes and dramatically reducing the cost of incidents.

## Quick Reference

- Install an error monitoring SDK (Sentry, Datadog, Bugsnag, etc.) early in the app entry point
- Capture unhandled exceptions, unhandled promise rejections, and React error boundaries
- Attach user context, release version, and environment to every event
- Configure alert thresholds and on-call routing so critical errors page the right team
- Capture failed network requests and production RUM signals such as Core Web Vitals

## Check

Check whether an error monitoring service is configured and capturing unhandled errors, promise rejections, React/framework-level errors, failed network requests, and production Core Web Vitals signals.

## Fix

How to install

The exact contents, by fingerprint
mdr add thedaviddias/front-end-checklist/error-monitoring@sha256:33ce52ea3ec12e6c

The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
