Get wifi state on real time (connected/disconnected) with wifi-state. While you are connected to a wireless network wifi-state will returns the current acces point information (essid, bssid, protocol, chanel, network interface, mode). Wifi-states will update access point information in real time each time you're connecting or disconnecting from a wireless access point. You can also fetch manually network information.

Install

$ npm install wifi-state --save

Usages

const wifiState = require('wifi-state')

wifiState.start() // start listening for network information

wifiState.on('connected', function(networkInfo) { // get live updates of network information
console.log(networkInfo)
/*
 { frequency: '5.18 ',
   protocol: 'IEEE 802.11',
   chanel: '36',
   bssid: 'FF:FF:FF:FF:FF:FF',
   essid: 'networkName',
   iface: 'wlp7s0',
   mode: 'Managed' }
*/
})

wifiState.on('disconnected', function(networkInfo) { // get live updates of network information
console.log(networkInfo)
// 'Not connected'
})

wifiState.stop() // Stop wifi-state listener, otherwise it will listening for new network informat[^0b91]ion for ever.

wifiState.networkInfo() // get manualy network information
 .then(networkInfo => console.log(networkInfo))
 .catch((err) => {console.log(err)})

• wifiState.on('XXXX', function() {}) needs wifiState.start() of having being declared.
• wifiState.networkInfo() works without wifiState.start().
• wifiState.networkInfo() return a promise.

Notes :

• This script only works on linux.
• This script requires iwevent to be installed (already installed on most linux distributions).
• This script only have been tested with one wireless card.

Changelog :

• wifiState.networkInfo() now returns a promise.
• Before failing, wifi-state will tries to get network information multiple times (e.g. if the connection to the access point takes a long time to be established).
