Guide

You can read the guide on the official Nestgram website, on Medium website or here

Install Nestgram

You need to install nestgram at first. You can do this using yarn or npm

yarn add nestgram
// or
npm i nestgram

Create main file

Our next step is creating the main file, so let's create the main.ts file

import { NestGram } from 'nestgram';
import { AppModule } from './app/app.module';

async function bootstrap(): Promise<void> {
  const bot = new NestGram('TOKEN', AppModule);
  await bot.start();
}

bootstrap();

At first, we imported nestgram and our AppModule, later we will create it. In the next step, we created a bootstrap function, in which we set up and run the project. The NestGram class takes arguments:

Argument	Name	Required
1	Bot token. You can get it here	Required
2	App module	Required
3	Config IPollingConfig or IWebhookConfig	Optional
4	Run config	Optional

Create app.module.ts

Let's create the app.module.ts file. In it, we will describe all available controllers and services

import { Module } from 'nestgram';
import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  controllers: [AppController],
  services: [AppService],
})
export class AppModule {}

At first, we imported Module class from nestgram, AppController and AppService also, that we will create later. Then we described our controllers and services in @Module decorator

Create app.controller.ts

Let's create the app.controller.ts file. In it, we will describe updates, that we want to handle

import { OnCommand, Controller } from 'nestgram';
import { AppService } from './app.service';

@Controller()
export class AppController {
  constructor(private readonly appService?: AppService) {}

  @OnCommand('start')
  start(): string {
    return 'Hello, world!';
  }
}

We have created a controller where we describe an update when the user writes /start, and we handle it by sending a message Hello, world!

Create app.service.ts

Let's create the app.service.ts file. In it, we will describe methods with working with db, that we will call in controller

import { Service } from 'nestgram';

@Service()
export class AppService {}

We can describe methods in AppService class, and call it in controller by this.appService

Run project

To run the project, open a terminal in the project directory and type:

npm run dev

Or build and run production:

npm run build && npm run prod
