throttleneck

A very basic NPM wrapper to call wondershaper from NPM scripts.

Overview

• Can be used to throttle outgoing/incoming egress of network adapters.

• Intended to be used with various network setups for local throttling and debugging/development purposes.

• For example, you could set up Internet Connection Sharing and then throttle the resulting wireless connection. This would enable bandwidth testing of devices connected to your local wireless connection.

Note : wondershaper is included as a git submodule see wondershaper README for more info

throttleneck quickstart

1. list available ethernet adapters

npm run ./node_modules/throttleneck/list-adapters

or use ifconfig

2. throttle egress - outgoing(upload) or incoming(download) or both

npm run ./node_modules/throttleneck/shape --KBPS_UP=500 --KBPS_DOWN=500

  }
