About
This library is used to get the fastest server from the list of servers (IP’s or host names). Many times same services are running in different regions to serve clients better. And this library will try to ping the list of servers using ICMP (Internet Control Message Protocol). Based on response time it will find the fastest server which is mostly nearest server.
Installation
npm install fastest-server
Usage
const FastestServer = ; const fastest stats = await FastestServer // fastest - will have fastest host.// stats - will be more information about response time and respose type.// {// fastest: 'google.com',// stats: [// { host: '172.217.19.14', response: 'REPLY', timeElapsed: 9 },// { host: 'google.com', response: 'REPLY', timeElapsed: 2 }// ]// }
Methods Exposed
(static) FastestServer.get( hosts: Array< String >, [timeout: number]): Promise<{ fastest: string, stats: Array<{ host: string, response: string , timeElapsed: numer }>}>
const fastest stats = await FastestServer; console; // google.comconsole;// [// { host: '172.217.19.14', response: 'REPLY', timeElapsed: 9 },// { host: 'google.com', response: 'REPLY', timeElapsed: 2 }// ]
response
will be one of the value from array:['REPLY', 'NA', 'DESTINATION_UNREACHABLE', 'SOURCE_QUENCH', 'REDIRECT', 'UNKNOWN']
timeElapsed
will be in milliseconds (ms
