## What it is
badjs-report is a JavaScript library that captures frontend JS errors by overriding window.onerror and reports them to a backend endpoint, with sampling, deduplication, offline logs, and manual reporting APIs. It is a client-side error monitoring and log reporting tool for web pages.

## Use cases
- monitor javascript errors on a web page
- report frontend exceptions to a server
- capture uncaught errors via window.onerror
- collect offline browser logs for debugging
- sample and dedupe repeated frontend error reports
- track user-side js errors in production

## When to choose
- you need lightweight client-side JS error capture and reporting in a legacy browser environment
- you want offline log buffering and manual error reporting hooks
- you need a simple drop-in onerror-based reporter with sampling and repeat suppression

## When to avoid
- you need an actively maintained solution - the project has had no releases since 2018
- you need a full frontend monitoring platform with performance metrics and dashboards
- you use modern frameworks where Sentry or similar SDKs offer richer integrations
