## Usage

Implement the client using something like:

```ts
// bot.ts

import { CoreClient } from "vylbot-core";

const client = new CoreClient();
client.start();
```

### Writing Commands

The code below will reply to the user with 'PONG' when they type {PREFIX}ping

```ts
// Ping.ts

import { Command, ICommandContext } from "vylbot-core";

export default class Ping extends Command {
	constructor() {
		super();
		this._roles = [ "Moderator" ];
		this._category = "General";
	}
	
	public override execute(context: ICommandContext) {
		context.message.reply('PONG');
	}
}
```

* **roles**: An array containing what roles the user needs in order to run the command.
* **category**: The category the role is part of, useful for categorising commands together in a help command.

The `context` parameter contains the following:
* **name**: The command name
* **args**: An array of arguments supplied with the command
* **message**: The Discord Message object for the command message sent

### Writing Events

The code below will log to the console 'Member Joined: {USERNAME}' when a member joins a server the bot is in

```ts
// Moderation.ts

import { Event } from "vylbot-core";
import { GuildMember } from "discord.js";

export class Moderation extends Event {
	public override guildMemberAdd(member: GuildMember) {
		console.log(`Member Joined: ${member.tag}`);
	}
}
```

The following events are supported:
* channelCreate(channel: Channel)
* channelDelete(channel: Channel | PartialDMChannel)
* channelUpdate(oldChannel: Channel, newChannel: Channel)
* guildBanAdd(guild: Guild, user: User)
* guildBanRemove(guild: Guild, user: User)
