# Views

## What are views?

Views are reusable handlers. You can create a view and call it at any time. View can send messages using the **Answer class**. For example, you can create your bot's menu using views

## Create view

View is a simple function that has a name in format NameView. To create view, just export function

{% hint style="info" %}
View function takes argument: [Answer](/nestgram/nestgram-features/answer-class.md) class

View function must have a name in NameView format
{% endhint %}

{% code title="menu.view\.ts" %}

```typescript
export async function MenuView(answer: Answer): Promise<void> {
  await answer.send('Menu');
}
```

{% endcode %}

## Call view

At first, you need to use view, import it to `views` field in your **module file**

{% code title="app.module.ts" %}

```typescript
import { Answer, Module } from 'nestgram';
import { AppService } from './app.service';
import { AppController } from './app.controller';
import { MenuView } from './menu.view.ts';

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

{% endcode %}

Then you can call it using `.view` **answer method**

{% hint style="info" %}
.view answer method takes argument: view id, e.g. for MenuView class it will be 'menu'. If you try to enter a view with haven't id, you will get an error
{% endhint %}

{% code title="app.controller.ts" %}

```typescript
import { Answer, Controller, GetAnswer, OnCommand } from 'nestgram';
import { AppService } from './app.service';

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

  @OnCommand('start')
  async start(@GetAnswer() answer: Answer) {
    await answer.view('menu');
  }
}
```

{% endcode %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://degreetpro.gitbook.io/nestgram/nestgram-features/views.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
