GoGram

Light Weight, Fast, Elegant Telegram MTProto API framework in Golang for building Telegram clients and bots.

Status

⭐️ Gogram is a modern, elegant and concurrent MTProto API framework. It enables you to easily interact with the main Telegram API through a user account (custom client) or a bot identity (bot API alternative) using Go.

Setup

Please note that Gogram requires Go 1.18 or later.

go get -u github.com/ivanezko/gogram/telegram

Getting Started

package main

import "github.com/ivanezko/gogram/telegram"

func main() {
	client, err := telegram.NewClient(telegram.ClientConfig{
		AppID: 6, AppHash: "<app-hash>",
		// StringSession: "<string-session>",
	})

	if err != nil {
		log.Fatal(err)
	}

	client.LoginBot("<bot-token>") // or client.Login("<phone-number>") for user account, or client.AuthPrompt() for interactive login

	client.On(telegram.OnMessage, func(message *telegram.NewMessage) error { // client.AddMessageHandler
			message.Reply("Hello from Gogram!")
        	return nil
	}, 
        telegram.FilterPrivate) // waits for private messages only

	client.Idle() // block main goroutine until client is closed
}

Doing Stuff

Sending a Message

client.SendMessage("username", "Hello from Gogram!")

client.SendDice("username", "🎲")

client.On("message:/start", func(m *telegram.NewMessage) error {
    m.Reply("Hello from Gogram!") // m.Respond("...")
    return nil
})

Sending Media

client.SendMedia("username", "<file-name>", &telegram.MediaOptions{ // filename/inputmedia,...
    Caption: "Hello from Gogram!",
    TTL: int32((math.Pow(2, 31) - 1)), //  TTL For OneTimeMedia
})

client.SendAlbum("username", []string{"<file-name>", "<file-name>"}, &telegram.MediaOptions{ // Array of filenames/inputmedia,...
    Caption: "Hello from Gogram!",
})

// with progress
var pm *telegram.ProgressManager
client.SendMedia("username", "<file-name>", &telegram.MediaOptions{
    Progress: func(a,b int) {
        if pm == nil {
            pm = telegram.NewProgressManager(a, 3) // 3 is edit interval
        }

        if pm.ShouldEdit(b) {
            fmt.Println(pm.GetStats(b)) // client.EditMessage("<chat-id>", "<message-id>", pm.GetStats())
        }
    },
})

Inline Queries

client.On("inline:<pattern>", func(iq *telegram.InlineQuery) error { // client.AddInlineHandler
	builder := iq.Builder()
	builder.Article("<title>", "<description>", "<text>", &telegram.ArticleOptions{
			LinkPreview: true,
	})

	return nil
})

Callback Queries

client.On("callback:<pattern>", func(cb *telegram.CallbackQuery) error { // client.AddCallbackHandler
    cb.Answer("This is a callback response", &CallbackOptions{
		Alert: true,
	})
    return nil
})
