Library for telegram bots written in pure go
Fetch with
go get github.com/NicoNex/echotron/v3A very simple implementation:
package main
import (
"log"
"github.com/NicoNex/echotron/v3"
)
type bot struct {
chatID int64
echotron.API
}
const token = "YOUR TELEGRAM TOKEN"
func newBot(chatID int64) echotron.Bot {
return &bot{
chatID,
echotron.NewAPI(token),
}
}
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatID, nil)
}
}
func main() {
dsp := echotron.NewDispatcher(token, newBot)
log.Println(dsp.Poll())
}Also proof of concept with self destruction for low ram usage
package main
import (
"log"
"time"
"github.com/NicoNex/echotron/v3"
)
type bot struct {
chatID int64
echotron.API
}
const token = "YOUR TELEGRAM TOKEN"
var dsp echotron.Dispatcher
func newBot(chatID int64) echotron.Bot {
var bot = &bot{
chatID,
echotron.NewAPI(token),
}
go bot.selfDestruct(time.After(time.Hour))
return bot
}
func (b *bot) selfDestruct(timech <- chan time.Time) {
select {
case <-timech:
b.SendMessage("goodbye", b.chatID, nil)
dsp.DelSession(b.chatID)
}
}
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatId, nil)
}
}
func main() {
dsp := echotron.NewDispatcher(token, newBot)
log.Println(dsp.Poll())
}package main
import "github.com/NicoNex/echotron/v3"
type bot struct {
chatID int64
echotron.API
}
const token = "YOUR TELEGRAM TOKEN"
func newBot(chatID int64) echotron.Bot {
return &bot{

}
}
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatID, nil)
}
}
func main() {

dsp.ListenWebhook("https://example.com:443/my_bot_token")
}
