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:
