npm package: @swagger-api/apidom-parser-adapter-asyncapi-yaml-3
Description: Parser adapter for parsing YAML documents into AsyncAPI 3.x.y namespace.
Author: Vladimir Gorej
Latest version: 1.10.1

# @swagger-api/apidom-parser-adapter-asyncapi-yaml-3

`@swagger-api/apidom-parser-adapter-asyncapi-yaml-3` is a parser adapter for following AsyncAPI specification versions defined in [YAML format](https://yaml.org/spec/1.2/spec.html):

- [AsyncAPI 3.0.0 specification](https://github.com/asyncapi/spec/blob/v3.0.0/spec/asyncapi.md)

Under the hood this adapter uses [@swagger-api/apidom-parser-adapter-yaml-1-2](https://github.com/swagger-api/apidom/tree/main/packages/apidom-parser-adapter-yaml-1-2)
to parse a source string into generic ApiDOM in [base ApiDOM namespace](https://github.com/swagger-api/apidom/tree/main/packages/apidom-core#base-namespace)

[//]: # (// TODO: The below link does not have content yet.)
which is then refracted with [AsyncApi 3.x.y Refractors](https://github.com/swagger-api/apidom/tree/main/packages/apidom-ns-asyncapi-3#refractors).

## Installation

After [prerequisites](https://github.com/swagger-api/apidom/blob/main/README.md#prerequisites) for installing this package are satisfied, you can install it
via [npm CLI](https://docs.npmjs.com/cli) by running the following command:

```sh
 $ npm install @swagger-api/@swagger-api/apidom-parser-adapter-asyncapi-yaml-3
```

## Parser adapter API

This parser adapter is fully compatible with parser adapter interface required by [@swagger-api/apidom-parser](https://github.com/swagger-api/apidom/tree/main/packages/apidom-parser#mounting-parser-adapters)
and implements all required properties.

### mediaTypes

Defines list of media types that this parser adapter recognizes.

```js
[
  'application/vnd.aai.asyncapi;version=3.0.0',
  'application/vnd.aai.asyncapi+yaml;version=3.0.0'
]
```

### detect

[Detection](https://github.com/swagger-api/apidom/blob/main/packages/apidom-parser-adapter-asyncapi-yaml-3/src/adapter.ts#L21) is based on a regular expression matching required AsyncApi 3.x.y specification symbols in YAML format.

### namespace

[//]: # (// TODO: Below link does not have content yet.)
This adapter exposes an instance of [AsyncApi 3.x.y ApiDOM namespace](https://github.com/swagger-api/apidom/tree/main/packages/apidom-ns-asyncapi-3#asyncapi-2xy-namespace).

### parse

`parse` function consumes various options as a second argument. Here is a list of these options:

Option | Type | Default | Description
--- | --- | --- | ---
<a name="specObj"></a>`specObj` | `Object` | [Specification Object](https://github.com/swagger-api/apidom/blob/main/packages/apidom-ns-asyncapi-3/src/refractor/specification.ts) | This specification object drives the YAML AST transformation to AsyncAPI 3.x ApiDOM namespace.
<a name="sourceMap"></a>`sourceMap` | `Boolean` | `false` | Indicate whether to generate source maps.
<a name="refractorOpts"></a>`refractorOpts` | `Object` | `{}` | Refractor options are [passed to refractors](https://github.com/swagger-api/apidom/tree/main/packages/apidom-ns-asyncapi-3#refractor-plugins) during refracting phase.

All unrecognized arbitrary options will be ignored.

## Usage

This parser adapter can be used directly or indirectly via [@swagger-api/apidom-parser](https://github.com/swagger-api/apidom/tree/main/packages/apidom-parser).

### Direct usage

During direct usage you don't need to provide `mediaType` as the `parse` function is already pre-bound
with [supported media types](#mediatypes).

```js
import { parse, detect } from '@swagger-api/apidom-parser-adapter-asyncapi-yaml-3';

// detecting
await detect('asyncapi: 3.0.0'); // => true
await detect('test'); // => false

// parsing
const parseResult = await parse('asyncapi: 3.0.0', { sourceMap: true });
```

### Indirect usage

You can omit the `mediaType` option here, but please read [Word on detect vs mediaTypes](https://github.com/swagger-api/apidom/tree/main/packages/apidom-parser#word-on-detect-vs-mediatypes) before you do so.

```js
import ApiDOMParser from '@swagger-api/apidom-parser';
import * as asyncApiYamlAdapter from '@swagger-api/apidom-parser-adapter-asyncapi-yaml-3';

const parser = new ApiDOMParser();

parser.use(asyncApiYamlAdapter);

const parseResult = await parser.parse('asyncapi: 3.0.0', { mediaType: asyncApiYamlAdapter.mediaTypes.latest('yaml') });
```
