Hello,

joi-to-swagger will only create schemas, the definition for example of parameters is not in the scope of that library.
I also want to point out, that joi-to-swagger will create OpenAPI v3 compliant schemas. In your example, you use a parameter with in: 'body', which is not OpenAPI v3 but Swagger (v2).

For your question, to create the components tree you described I have written the following code:

const j2s = require('joi-to-swagger');
const joi = require('joi');

const pagination = joi.object({
	perPageRecords: joi.number().integer(),
	pageNo: joi.number().integer(),
}).meta({ className: 'pagination' });

const sort = joi.object({
	sorts: joi.array().items(joi.object({
		fieldName: joi.string(),
		direction: joi.string(),
	}).unknown()),
}).unknown().label('sort').meta({ className: 'sort' });

const components = { schemas: {} };

Object.assign(components.schemas, j2s(pagination, components).components.schemas);
Object.assign(components.schemas, j2s(sort, components).components.schemas);

console.log(JSON.stringify(components, null, 2));

resulting in

{
  "schemas": {
    "pagination": {
      "type": "object",
      "properties": {
        "perPageRecords": {
          "type": "integer"
        },
        "pageNo": {
          "type": "integer"
        }
      },
      "additionalProperties": false
    },
    "sort": {
      "type": "object",
      "properties": {
        "sorts": {
          "type": "array",
          "items": {
            "type": "object",
            "properties": {
              "fieldName": {
                "type": "string"
              },
              "direction": {
                "type": "string"
              }
            }
          }
        }
      },
      "title": "sort"
    }
  }
}
