network-emulation-conditions

Settings for network emulation conditions (e.g Regular 3G, 2G, WiFi, DSL, GPRS and so on). Useful for anyone building web performance tooling.

Install

$ npm install --save network-emulation-conditions

Usage

const conditions = require('network-emulation-conditions');
 
console.log(conditions.REGULAR_3G);
//=>
{ title: 'Regular 3G',
  download: 96000,
  upload: 32000,
  latency: 100 }

These correlate to download throughput, upload throughput and network latency. REGULAR_3G for example is calculated as 750 * 1024 / 8 (750kbps download), 250 * 1024 / 8 (250kbps upload) and 100ms latency.

Available conditions

• GPRS
• REGULAR_2G
• GOOD_2G
• REGULAR_3G
• GOOD_3G
• REGULAR_4G
• DSL
• WIFI

These network emulation conditions match those used in the Chrome Developer Tools:
