Overview

This plugin will create an end-point that analyzes your Actionhero routes and provides JSON for swagger to consume.

For simplicity, a default index.html is provided under the ./public/swagger folder. Contents are directly from the pre-compiled swagger-ui package.

Below is an example of how an action can be defined:

const { Action, api } = require('actionhero')

module.exports = class MyAction extends Action {
  constructor () {
    super()
    this.name = 'myAction'
    this.description = 'A detailed description of my action.'
    this.responseSchemas = {
      // By default set this 200 property to provide a sample response in the form of a JSON schema
      // object.  Since schemas can get pretty bulky, consider requiring a file instead of having
      // everything in-line.  E.g. '200': require('myResponseSchema.js')
      //
      // It's also possible to automate schema generation with json-schema-generator with json-patch.
      '200': {
        description: 'Sample http 200 response',
        schema: {
          type: 'object',
          properties: {
            'marco': {
              type: 'string',
              example: 'polo'
            }
          }
        }
      }
    }
    this.inputs = {
      required: ['myParam'],
      // Each input parameter needs to be defined as a property, including input parameters for routes.
      myParam: {
        description: 'A detailed description of myParam',
        required: true,
        // Define this as an enum if you want to specify the list of possible values.
        enum: ['value1', 'value2', 'value3']
      }
    }
    // For post/put http requests, describing the body is set here in JSON schema form.
    this.modelSchema = {
      myParam: {
        type: 'string',
        example: 'value1'
      },
      otherData: {
        type: 'string',
        example: '-data1'
      }
    }
    // A tag will group/organize actions together
    this.tags = ['Examples']
  }

  async run (data) { }
}
  • You can access the http://127.0.0.1:8080/swagger and see your project's documentation:

alt tag

LIMITATIONS:

  • Using an API key with a file-multiform-upload doesn't work as expected

TODOs:

  • Make swagger html files optional or easily over-ridden
  • Include tests

Advanced Configuration

A ./config/swagger.js file will be created which will store your configuration.

exports.default = {
  swagger: (api) => {
    return {
      // Should be changed to hit www.yourserver.com.  If this is null, defaults to ip:port from
      // internal values or from hostOverride and portOverride.
      baseUrl: '127.0.0.1:8080',
      // Specify routes that don't need to be displayed
      ignoreRoutes: ['/swagger'],
      // Specify how routes are grouped
      routeTags: {
        'basics': ['showDocumentation', 'status']
      },
      // Generate documentation for simple actions specified by action-name
      documentSimpleRoutes: true,
      // Generate documentation for actions specified under config/routes.js
      documentConfigRoutes: true,
      // Set true if you want to organize actions by version
      groupByVersionTag: true,
      // For simple routes, groups all actions under a single category
      groupBySimpleActionTag: true,
      // In some cases where actionhero network topology needs to point elsewhere.  If null, uses
      // api.config.swagger.baseUrl
      hostOverride: null,
      // Same as above, if null uses the internal value set in config/server/web.js
      portOverride: null
    }
  }
}
