Installation

$ npm i nestjs-telegraf

Once the installation process is complete, we can import the TelegrafModule into the root AppModule:

import { Module } from '@nestjs/common';
import { TelegrafModule } from 'nestjs-telegraf';

@Module({
  imports: [
    TelegrafModule.forRoot({
      token: 'TELEGRAM_BOT_TOKEN',
    })
  ],
})
export class AppModule {}

Then add some decorators into the app.service.ts for handling Telegram bot API updates:

import { Injectable } from '@nestjs/common';
import {
  Start,
  Help,
  On,
  Hears,
  Context,
} from 'nestjs-telegraf';

@Injectable()
export class AppService {
  @Start()
  start(ctx: Context) {
    ctx.reply('Welcome');
  }

  @Help()
  help(ctx: Context) {
    ctx.reply('Send me a sticker');
  }

  @On('sticker')
  on(ctx: Context) {
    ctx.reply('👍');
  }

  @Hears('hi')
  hears(ctx: Context) {
    ctx.reply('Hey there');
  }
}
