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
