Usage (Deno)

You can import the package from https://deno.land/x/harmony/mod.ts (with latest version) or can add a version too, and raw GitHub URL (latest unpublished version) https://raw.githubusercontent.com/harmonyland/harmony/main/mod.ts too.

We also have a (fancy) custom registry for importing Harmony! It's at code.harmony.rocks, example import URL: https://code.harmony.rocks/v2.6.1.

Usage (Node.js)

You can install and use the NPM package published under @harmonyland/harmony.

Documentation

Documentation is available main branch or latest stable version (v2.6.1). You can also check out the guide.

Example

For a quick example, run this:

deno run --allow-net https://deno.land/x/harmony@v2.6.1/examples/ping.ts

And input your bot's token.

Here is a small example of how to use harmony,

import {
  Client,
  Message,
  GatewayIntents
} from 'https://deno.land/x/harmony@v2.6.1/mod.ts'

const client = new Client({
  intents: [
    'GUILDS',
    'DIRECT_MESSAGES',
    'GUILD_MESSAGES'
  ],
  // token: optionally specify, otherwise DISCORD_TOKEN from env is used
})

// Listen for event when client is ready (Identified through gateway / Resumed)
client.on('ready', () => {
  console.log(`Ready! User: ${client.user?.tag}`)
})

// Listen for event whenever a Message is sent
client.on('messageCreate', (msg: Message): void => {
  if (msg.content === '!ping') {
    msg.channel.send(`Pong! WS Ping: ${client.gateway.ping}`)
  }
})

// Connect to gateway
client.connect()

Or with CommandClient!

import {
  CommandClient,
  Command,
  CommandContext,
  GatewayIntents
} from 'https://deno.land/x/harmony@v2.6.1/mod.ts'

const client = new CommandClient({
  prefix: '!',
  intents: [
    'GUILDS',
    'DIRECT_MESSAGES',
    'GUILD_MESSAGES'
  ],
  // token: optionally specify, otherwise DISCORD_TOKEN from env is used
})

// Listen for event when client is ready (Identified through gateway / Resumed)
client.on('ready', () => {
  console.log(`Ready! User: ${client.user?.tag}`)
})

// Create a new Command
class PingCommand extends Command {
  name = 'ping'

  execute(ctx: CommandContext) {
    ctx.message.reply(`pong! Ping: ${ctx.client.gateway.ping}ms`)
  }
}

client.commands.add(PingCommand)

// Connect to gateway
client.connect()

Or with Decorators!

import {
  event,
  CommandClient,
  command,
  CommandContext,
  GatewayIntents
} from 'https://deno.land/x/harmony@v2.6.1/mod.ts'

class MyClient extends CommandClient {
  constructor() {
    super({
      prefix: ['!', '!!'],
      caseSensitive: false,
      intents: [
        'GUILDS',
        'DIRECT_MESSAGES',
        'GUILD_MESSAGES'
      ],
      // token: optionally specify, otherwise DISCORD_TOKEN from env is used
    })
  }

  @event()
  ready(): void {
    console.log(`Logged in as ${this.user?.tag}!`)
  }

  @command({ aliases: 'pong' })
  Ping(ctx: CommandContext): void {
    ctx.message.reply('Pong!')
  }
}

new MyClient().connect()
