Allows easy conversion of SteamIDs from various formats

SteamID Interop

SteamID interop allows you to decode and encode SteamIDs to various formats, such as 32-bit, 64-bit and the new Steam3 format.

var SteamID = require('steamid-interop');

var id = SteamID.decode('STEAM_0:1:1');
console.log(id.toString('64')); // 76561197960265731
console.log(id.toString('32')); // STEAM_0:1:1
console.log(id.toString('steam3')); // [U:1:3]
console.log(id.toString()); // Defaults to 64-bit when no encoding method specified.
