## Description

[AsyncApi](https://www.asyncapi.com/) module for [Nest](https://github.com/nestjs/nest).

Generate [AsyncApi](https://www.asyncapi.com/) documentation (for event-based services, like websockets) in a similar

to [nestjs/swagger](https://github.com/nestjs/swagger) fashion.

### [Live Preview](https://flamewow.github.io/nestjs-asyncapi/live-preview)

[AsyncApi playground](https://playground.asyncapi.io/?load=https://raw.githubusercontent.com/asyncapi/asyncapi/v2.1.0/examples/simple.yml)

## Installation

full installation (with chromium)

```bash

$ npm i --save nestjs-asyncapi

```

nestjs-async api package doesn't require chromium (which is required by asyncapi lib), so u can skip chromium

installation by setting PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true environment variable.

```bash

$ PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true npm i --save nestjs-asyncapi

```

## Quick Start

Include AsyncApi initialization into your bootstrap function.

```typescript

async function bootstrap() {

    const app = await NestFactory.create(AppModule);

    const asyncApiOptions = new AsyncApiDocumentBuilder()

        .setTitle('Feline')

        .setDescription('Feline server description here')

        .setVersion('1.0')

        .setDefaultContentType('application/json')

        .addSecurity('user-password', {type: 'userPassword'})

        .addServer('feline-ws', {

            url: 'ws://localhost:3000',

            protocol: 'socket.io',

        })

        .build();

    const asyncapiDocument = await AsyncApiModule.createDocument(app, asyncApiOptions);

    await AsyncApiModule.setup(docRelPath, app, asyncapiDocument);

    // other bootstrap procedures here

    return app.listen(3000);

}

```

AsyncApi module explores `Controllers` & `WebSocketGateway` by default.

In most cases you won't need to add extra annotation,

but if you need to define asyncApi operations in a class that's not a controller or gateway use the `AsyncApi` class

decorator.

Mark pub/sub methods via `AsyncApiPub` or `AsyncApiSub` decorators


```typescript

class CreateFelineDto {

    @ApiProperty()

    demo: string;

}

@Controller()

class DemoController {

    @AsyncApiPub({

        channel: 'create/feline',

        message: {

            payload: CreateFelineDto

        },

    })

    async createFeline() {

        // logic here

    }

    @AsyncApiSub({

        channel: 'create/feline',

        message: {

            payload: CreateFelineDto

        },

    })

    async createFeline() {

        // logic here

    }

}

```
