Base settings for the client

import { join } from 'path'
import { TwitchCommandClient, TwitchChatMessage } from 'twitch-core'

const client = new TwitchCommandClient({
  username: 'vs_code',
  oauth: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
  channels: ['archikoff', 'le_xot'],
  botOwners: ['vs_code']
})

client.on('connected', () => {})

client.on('join', channel => { })

client.on('error', err => { })

client.on('message', (msg: TwitchChatMessage) => { })

client.provider.set(
  join(__dirname, 'config/text-commands.json'),
  join(__dirname, 'config/commands.json')
)

client.registerTextCommands()

client.registerDefaultCommands()

client.registerCommandsIn(
  join(__dirname, '/commands')
)

client.connect()

Client extends of EventEmitter, so you can easily subscribe to his events.

You can register the bot's default commands (!commands, !help, etc.), using method registerDefaultCommands.

Method registerTextCommands allows loading text commands, using text-commands.json config.

Create folder called commands, that will contain all your commands.

Don't forget to call method registerCommandsIn, to register your own commands.

Creating a standard command

import { TwitchChatCommand, TwitchCommandClient, TwitchChatMessage, CommandOptions } from 'twitch-core'

class Example extends TwitchChatCommand {
  constructor(client: TwitchCommandClient, options: CommandOptions) {
    super(client, {
      name: 'example',
      userlevel: 'everyone',
      description: 'Example command',
      examples: [
        '!example',
        '!example <args>'
      ]
    })
  }

  async run(msg: TwitchChatMessage, args: string[]) {
    msg.reply(`Args -> ${args.join(' ')}`)
  }
}

export default Example

Command with named arguments

import { TwitchChatCommand, TwitchCommandClient, TwitchChatMessage, CommandOptions } from 'twitch-core'

interface CommandArgs {
  name: string
  age: number
  bool: boolean
}

class ExampleArgs extends TwitchChatCommand {
  constructor(client: TwitchCommandClient, options: CommandOptions) {
    super(client, {
      name: 'example-args',
      userlevel: 'everyone',
      description: 'Example of command with named arguments',
      examples: [
        '!example',
        '!example <args>'
      ],
      {
        name: 'name',
        type: String,
        defaultValue: 'Text string'
      },
      {
        name: 'age',
        type: Number,
        defaultValue: 22
      },
      {
        name: 'bool',
        type: Boolean,
        defaultValue: false
      }
    })
  }

  async run(msg: TwitchChatMessage, { name, age, bool }: CommandArgs) {
    msg.reply(`Args -> ${name} ${age} ${bool}`)
  }
}

export default ExampleArgs
