It's kind of overlay for github.com/osztenkurden/csgogsi package - if you want to connect this package to socket.io server, this will make your life easier, for example - during creation of the HUD. Additionaly, it returnes all types of CSGOGSI package.

npm install csgogsi-socket

import { GSISocket } from 'csgogsi-socket';

const GSI = GSISocket('localhost:1337', 'update');

GSI.on('roundEnd', team => {
    console.log(`Team  ${team.name} win!`);
});
GSI.on('bombPlant', player => {
    console.log(`${player.name} planted the bomb`);
});

GSISocket() function takes two arguments - first, address of socket.io server, and second - name of the event that gives the raw CSGO GSI data.

It returns socket and CSOGSI object (and all interfaces from CSGOGSI), so all methods from github.com/osztenkurden/csgogsi documentation will apply.
