@swagger-api/apidom-ns-workflows-1

@swagger-api/apidom-ns-workflows-1 contains ApiDOM namespace specific to Workflows 1.0.0 specification.

Installation

You can install this package via npm CLI by running the following command:

 $ npm install @swagger-api/apidom-ns-workflows-1

Workflows 1.0.0 namespace

Workflows 1.0.0 namespace consists of number of elements implemented on top of primitive ones.

import { createNamespace } from '@swagger-api/apidom-core';
import workflows1Namespace from '@swagger-api/apidom-ns-workflows-1';

const namespace = createNamespace(workflows1Namespace);

const objectElement = new namespace.elements.Object();
const workflowsElement = new namespace.elements.WorkflowsSpecification1();

When namespace instance is created in this way, it will extend the base namespace with the namespace provided as an argument.

Elements from the namespace can also be used directly by importing them.

import { WorkflowsSpecification1Element, InfoElement } from '@swagger-api/apidom-ns-workflows-1';

const infoElement = new InfoElement();
const workflowsElement = new WorkflowsSpecification1Element();

Predicates

This package exposes predicates for all higher order elements that are part of this namespace.

import { isWorkflowsSpecification1Element, WorkflowsSpecification1Element } from '@swagger-api/apidom-ns-workflows-1';

const workflowsElement = new WorkflowsSpecification1Element();

isWorkflowsSpecification1Element(workflowsElement); // => true

Traversal

Traversing ApiDOM in this namespace is possible by using visit function from apidom package. This package comes with its own keyMap and nodeTypeGetter. To learn more about these visit configuration options please refer to @swagger-api/apidom-ast documentation.

import { visit } from '@swagger-api/apidom-core';
import { WorkflowsSpecification1Element, keyMap, getNodeType } from '@swagger-api/apidom-ns-workflows-1';

const element = new WorkflowsSpecification1Element();

const visitor = {
  WorkflowsSpecification1Element(workflowsElement) {
    console.dir(workflowsElement);
  },
};

visit(element, visitor, { keyMap, nodeTypeGetter: getNodeType });

Refractors

Refractor is a special layer inside the namespace that can transform either JavaScript structures or generic ApiDOM structures into structures built from elements of this namespace.

Refracting JavaScript structures:

import { InfoElement } from '@swagger-api/apidom-ns-workflows-1';

const object = {
    title: 'my title',
    summary: 'my summary',
    description: 'my description',
    version: '0.1.0',
};

InfoElement.refract(object); // => InfoElement({ title, summary, description, version })

Refracting generic ApiDOM structures:

import { ObjectElement } from '@swagger-api/apidom-core';
import { InfoElement } from '@swagger-api/apidom-ns-workflows-1';

const objectElement = new ObjectElement({
    title: 'my title',
    summary: 'my summary',
    description: 'my description',
    version: '0.1.0',
});

InfoElement.refract(objectElement); // => InfoElement({ title = 'my title', summary = 'my summary', description = 'my description', version = '0.1.0' })

Refractor plugins

Refractors can accept plugins as a second argument of refract static method.

import { ObjectElement } from '@swagger-api/apidom-core';
import { InfoElement } from '@swagger-api/apidom-ns-workflows-1';

const objectElement = new ObjectElement({
    title: 'my title',
    summary: 'my summary',
    description: 'my description',
    version: '0.1.0',
});

const plugin = ({ predicates, namespace }) => ({
  name: 'plugin',
  pre() {
      console.dir('runs before traversal');
  },
  visitor: {
    InfoElement(infoElement) {
      infoElement.version = '2.0.0';
    },
  },
  post() {
      console.dir('runs after traversal');
  },
});

InfoElement.refract(objectElement, { plugins: [plugin] }); // => InfoElement({ title = 'my title', description = 'my description', version = '2.0.0' })

You can define as many plugins as needed to enhance the resulting namespaced ApiDOM structure. If multiple plugins with the same visitor method are defined, they run in parallel (just like in Babel).

Replace Empty Element plugin

This plugin is specific to YAML 1.2 format, which allows defining key-value pairs with empty key, empty value, or both. If the value is not provided in YAML format, this plugin compensates for this missing value with the most appropriate semantic element type.

import { parse } from '@swagger-api/apidom-parser-adapter-yaml-1-2';
import { refractorPluginReplaceEmptyElement, WorkflowsSpecification1Element } from '@swagger-api/apidom-ns-workflows-1';

const yamlDefinition = `
workflows: 1.0.0
info:
`;
const apiDOM = await parse(yamlDefinition);
const workflowsElement = WorkflowsSpecification1Element.refract(apiDOM.result, {
  plugins: [refractorPluginReplaceEmptyElement()],
});

// =>
// (WorkflowsSpecification1Element
//   (MemberElement
//     (StringElement)
//     (StringElement))
//   (MemberElement
//     (StringElement)
//     (InfoElement)))

// => without the plugin the result would be as follows:
// (WorkflowsSpecification1Element
//   (MemberElement
//     (StringElement)
//     (StringElement))
//   (MemberElement
//     (StringElement)
//     (StringElement)))
