JSPM – event-loop-lag@1.0.0

Package Exports

event-loop-lag

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (event-loop-lag) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

#event-loop-lag

Measures Node.js event loop lag.

var interval = 1000; // how often to refresh our measurement
var lag = require('event-loop-lag')(interval);

console.log('event loop lag is %d', lag());

event-loop-lag(number)

event-loop-lag accepts a number of milliseconds representing how often to refresh the event loop lag measurement and returns a function you can call to receive the latest lag measurement.

app.use(function*(next){
  if ('/lag' == this.url)
    this.body = lag();
  else
    yield next;
})
