x-webhooks generates only one entry in resulting JSON

[Aleksey Maltsev]

Describe the bug
I have more than one 'x-webhooks' entries in swagger files. After compilation only one webhook remains in resulting JSON.

To Reproduce

1. Create swagger file with 2 or more 'x-webhhoks' sections
2. Run compilation
3. Check the 'x-webhooks' section in result JSON - it contains only latest webhook information

Expected behavior
'x-webhooks' section contains all the webhooks from source YAMLs.

Desktop:

• MaOS 12.6
• Node 18.0.0
• swagger-jsdoc@6.2.5

Additional context

YAML example:

// wh-example.js

/**
 * Example 1
 *
 * @swagger
 * x-webhooks:
 *  newCat:
 *    post:
 *      description: Information about a new cat in the systems
 *      tags:
 *        - pet
 *      requestBody:
 *        content:
 *          application/json:
 *            schema:
 *              $ref: "#/components/schemas/Cat"
 *      responses:
 *        "200":
 *          description: Return a 200 status to indicate that the data was received successfully
 */

/**
 * Example 2
 *
 * @swagger
 * x-webhooks:
 *  newDog:
 *    post:
 *      description: Information about a new dog in the systems
 *      tags:
 *        - pet
 *      requestBody:
 *        content:
 *          application/json:
 *            schema:
 *              $ref: "#/components/schemas/Dog"
 *      responses:
 *        "200":
 *          description: Return a 200 status to indicate that the data was received successfully
 */

Executable code example:

// wh-compile.js
const swaggerJsDoc = require('swagger-jsdoc')

const result = swaggerJsDoc({
  swaggerDefinition: {
    info: {
      title: 'Example with extensions',
      version: '0.0.1'
    }
  },
  apis: ['./wh-example.js']
})

console.assert(result['x-webhooks'].newCat, 'Cat is here')
console.assert(result['x-webhooks'].newDog, 'Dog is here')
console.log(result['x-webhooks'])

Command:

node wh-compile

Current result:

Assertion failed: Cat is here
{
  newDog: {
    post: {
      description: 'Information about a new dog in the systems',
      tags: [Array],
      requestBody: [Object],
      responses: [Object]
    }
  }
}

Expected result:

{
  newCat: {
    post: {
      description: 'Information about a new cat in the systems',
      tags: [Array],
      requestBody: [Object],
      responses: [Object]
    }
  },
  newDog: {
    post: {
      description: 'Information about a new dog in the systems',
      tags: [Array],
      requestBody: [Object],
      responses: [Object]
    }
  }
}

Hints

Where the problem is:
specification.js

swaggerObject[property] = annotation[property];

How to fix it:

swaggerObject[property] = mergeDeep(
  swaggerObject[property],
  annotation[property]
)
