grammY commands

This plugin provides a convenient way to define and manage commands for your grammY bot. It simplifies the process of setting up commands with scopes and localization.

Installation

npm i @grammyjs/commands

Usage

The main functionality of this plugin is to define your commands, localize them, and give them handlers for each scope, like so:

import { Bot } from "grammy";
import { CommandGroup } from "@grammyjs/commands";

const bot = new Bot("<telegram token>");

const myCommands = new CommandGroup();

myCommands.command("start", "Initializes bot configuration")
  .localize("pt", "start", "Inicializa as configurações do bot")
  .addToScope(
    { type: "all_private_chats" },
    (ctx) => ctx.reply(`Hello, ${ctx.chat.first_name}!`),
  )
  .addToScope(
    { type: "all_group_chats" },
    (ctx) => ctx.reply(`Hello, members of ${ctx.chat.title}!`),
  );

// Calls `setMyCommands`
await myCommands.setCommands(bot);

// Registers the command handlers
bot.use(myCommands);

bot.start();

It is very important that you call bot.use with your instance of the Commands class. Otherwise, the command handlers will not be registered, and your bot will not respond to those commands.

Context shortcuts

This plugin provides a shortcut for setting the commands for the current chat. To use it, you need to install the commands flavor and the plugin itself, like so:

import { Bot, Context } from "grammy";
import { CommandGroup, commands, CommandsFlavor } from "@grammyjs/commands";

type BotContext = CommandsFlavor;

const bot = new Bot<BotContext>("<telegram_token>");
bot.use(commands());

bot.on("message", async (ctx) => {
  const cmds = new CommandGroup();

  cmds.command("start", "Initializes bot configuration")
    .localize("pt", "start", "Inicializa as configurações do bot");

  await ctx.setMyCommands(cmds);

  return ctx.reply("Commands set!");
});

bot.start();
