mirror-selector

Find fastest mirror to establish a TCP connection

Usage sample:

This lib find the fastest link to a server.

Classic usage:

You want to find the closest mirror to connect to it. See test file for a code sample that find the closest debian deb mirror server.

itinerant usage.

You have a database in your lan, that you can access with a VPN. But you do not want to use the VPN when your a connected to the same lan. Give thw VPN IP and the LAN IP to this API and use the fastest link to access the database.

code sample

My redis database can be access as localhost, local network, or VPN.

import getFastest from '.';

async code() {
    const server = await getFastest([
        {host: '127.0.0.1', port: 6379},
        {host: '192.168.1.4', port: 6379},
        {host: '10.0.10.4', port: 6379}\
    ], { timeout: 2000 });
    console.log('best link is: ', server);
}

This call will return me a localhost access if I'm on the server, a local access if I'm on the rigth network, a VPN access if I'm out of office, and off course will throw an Error if I have no access to my redis.
