## What it is
A Node.js library that monitors event loop lag and reports when the process is too busy to accept more work. It lets servers shed load early with a 503 response so they stay responsive under extreme traffic.

## Use cases
- keep a node server responsive under heavy load
- return 503 when the event loop is overloaded
- monitor event loop lag in node.js
- add load shedding middleware to express
- prevent a node process from falling over during traffic spikes

## When to choose
- you run a Node.js HTTP server that must degrade gracefully instead of timing out under overload
- you want a tiny, dependency-free way to detect event loop saturation

## When to avoid
- you need actively maintained software with recent releases and support
- you are not on Node.js or want load shedding handled by an external proxy or load balancer

## Facets
- artifact type: library
- maturity: maintenance
- function: middleware, monitoring, rate-limiting, http-server
- domain: backend, web-development, performance
- platform: -
- tags: event-loop-lag, load-shedding, overload-protection, express-middleware, nodejs, web-server
