如何使用分片管理器从ShardClientUtil访问shardArgs？

Question

I'm setting up a Bot using Discord.JS and want to pass the shardArgs option from the ShardingManager to the ShardClient . How do I access the option ( shardArgs ) from the ShardClientUtil ?

// ShardManager.js
const Discord = require('discord.js');

const Manager = new Discord.ShardingManager('./Main.js', {
     shardArgs: ["shard args to be passed through"]
});

Manager.spawn(1);

I've tried using .fetchClientValues() :

// Main.js
const Discord = require('discord.js');
const client = new Discord.Client();

client.shard.fetchClientValues('manager.shardArgs') 
   .then(results => {
    console.log(results);
   })
   .catch(console.error);

client.login("token");

I've tried many different things, I even checked the object in a debugger, but I was unable to find shardArgs so I'm not sure where I'm supposed to access it from.

I expect shardArgs to be "shard args to be passed through" , while at the moment I'm getting null .

The shardArgs are actually passed around a bit:

• First to Shard 's constructor
• Then to Shard#spawn
• Finally to child_process.fork (which will start the shard's process)

You can access your array in your shards via process.argv . (No need for IPC)

Mind that the first entry is the exeuctable (node) and the second is the file being executed (Main.js), the third and up entries are your array's.

As an example logging process.argv in your Main.js file might log:
['usr/bin/node', '/home/bot/Main.js', 'shard args to be passed through']
