average-requests-per-minute

Quick-and-dirty avereage-reqs-per-min handler. I've based it on [Response time] (https://www.npmjs.com/package/response-time).

This module returns a middleware that counts requests per minute (or other interval). It triggers a handler every interval seconds.

Disclaimer: it's very simple, trivial, keeps things in memory, and does not verify all the parameters. It is not tested well (yet), so use at your own risk.

Installation

$ npm install average-requests-per-minute

API

averageRequestsPerMinute(options)

Create a middleware that takes up to three parameters parameter, handler, inverval and freq.

Options

The options object holds mandatory handler and optional count and freq params.

handle

Handler is a simple function called every inverval seconds with numRequests.

inverval

inverval param (default 60) in seconds represents interval to track.

Examples

express/connect

let express = require('express');
let reqsPerMin = require('average-requests-per-minute');

let app = express();

app.use(reqsPerMin({

  handler: num => console.log(`Last minute there were ${num} requests.`)
}));

app.get('/',(req, res) => res.send('hello, world!'));

Or with a different interval:

let middleware = require('average-requests-per-minute');

let app = express();

app.use(middleware({

  inverval: 600,
  handler: num => console.log(`There were ${num} requests in the last 10 minutes.`)
}));

app.use((req, res) => res.send('Hello world.'));

TODO

• add tests for everything
• verify params
