Usage
Standalone
The pressure monitor is a class that can be used anywhere:

const monitor = new PressureMonitor({
maxEventLoopUtilization: 0.8,
});
monitor.overloaded; // true | false
Express
The library also exports an express middleware that can be used to throw an Error when the pressure monitor reports overloaded:
import express from 'express';
import { handlePressure } from '@directus/pressure';
const app = express();
app.use(
handlePressure({
maxEventLoopUtilization: 0.8,
}),
);
