ipMonitor.on('change', (prevIp, newIp) => {
    console.log(`IP changed from ${prevIp} to ${newIp}`);
});
 
ipMonitor.on('error', (error) => {
    console.error(error);
});
 
ipMonitor.start();
 
 

with custom configuration

const IpMonitor = require('ip-monitor');
const ipMonitor = new IpMonitor({
    pollingInterval: 36000,
    verbose: true,
    externalIp: {
        timeout: 1000,
        getIP: 'parallel',
        services: ['http://ifconfig.co/x-real-ip', 'http://icanhazip.com/'],
        replace: true,
        verbose: true
    }
});
 
ipMonitor.on('change', (prevIp, newIp) => {
    console.log(`IP changed from ${prevIp} to ${newIp}`);
});
 
ipMonitor.on('error', (error) => {
    console.error(error);
});
 
ipMonitor.start();

Configuration

new IpMonitor([config]) accepts a configuration object with the following optional properties:

• pollingInterval: <Integer>: how often to poll for ip changes, default 1 day
• externalIp: <Object>: configuration passed directly to external-ip

Methods

• .start(): start watching
• .stop(): stop watching
• .poll(): poll for ip manually

Events

• change: fired when the external ip has changed. it will also fire the first time .start() or .poll() are invoked.
• error: typical error handling here
