Apps

You can extend Aidbox with custom Apps. The app can define custom resources, custom endpoints, and subscribe to hooks or subscriptions. The app is a standalone service which will work with Aidbox to implement your specific app. App should be registered in Aidbox.

You define the App using Aidbox SDK for your language and should not reverse engineer internal API, because it can be subject to change.

App Resource

To define the App, we should provide the app manifest:

resourceType: App
id: myorg.myapp  # id of your application
apiVersion: 1    # App API version
type: app
endpoint:        # communication protocol between aidbox and app
   url: https://my.service.com:8888
   type: http-rpc         # type of protocol - http-rpc | ws-rpc 
   secret: <yoursercret>  # will be used to secure aidbox - app communication
entities: <Resource's Definitions, Profiles & Hooks>
operations: <Operation's Definitions>
subscriptions: <Subscriptions>

endpoint

In the endpoint section, you describe how Aidbox will communicate with your service.

Key	type	required	Options	default	description
type	string	true	http-rpc | ws-rpc	http-rpc	Protocol of communication
url	string	true			Url of service to communicate
secret	string				Secret key used for communication

entities

In the entities section of the App manifest, you can extend existing resources, define custom profiles, or hook into lifecycle:

entities:

Patient: # existing resource type
  attrs:
     # here we devine extension `race` for patient
     race: { extensionUrl: 'https://myapp/race', type: 'code' }
  hooks: # resource life cycle hooks
    before_create: # map of hooks <hook-id>: { config-map }
       notify_on_patient: { emails: ['[e-mail]'] }

As well as define custom resources:

entities:

User: # custom resource type
  attrs:
     email:    { type: 'email', isRequred: true }
     password: { type: 'password' }
     active:   { type: 'boolean' }
     patient:  { type: 'Reference', refers: ['Patient'] }
     settings:  
        attrs:
           theme: { type: 'string', enum: ['black', 'white'] }
  hooks:
     before_create:
        check_ldap: {}
     after_create:
        save_to_third_paty: {}
  profiles:
     user-uniq-email: 
       type: sql 
       query: SELECT true FROM "User" WHERE resource->>'email' == {{ .email }}
       message: Email is already taken

In the entities section, you define resources as a map <resourceType> : <resourceStructure> :

entities:
  Patient: <structure>
  User: <structure>
  Payment: <structure>

Resource structure is defined by keyword attrs{ <element-name>: <element-definition> ... }

entities:

User:
  attrs:
    email: <element-definition>
    password: <element-definition>
  profiles: <profiles-definition>
  hooks: <hooks-definition>

At the root of resource definition, you can also define hooks and profiles for this resource.

Element definition will be translated into Attribute Meta-Resource and have the following properties:

name	type	Description
type	code	Primitive or Complex Type name

operations

In the operation section, you define Custom REST operations as a map <operation-id>: <operation-definition> and access policy (which will be bound to this operation):

operations:

daily-patient-report:
  method: GET
  path: ['Patient', '$daily-report', { name: 'date'} ]
register-user:
  method: POST
  path: [ 'User', '$register' ]
  policies: 
     register-user: {  engine: allow }

resources

In the resources section, you can provide other meta-resources for Aidbox in the form {resourceType: {id: resource}}

resources:

# resource type
AccessPolicy:
   # resource id
   public-policy:
      # resource body
      engine: allow
      link:
        - {id: 'opname', resourceType: 'Operation'}

hooks

Aidbox will provide a set of hooks you can hook-in to customize its behavior:

subscriptions

In the subscription section, you can define subscriptions (a special type of hooks, which do not need a response). You can subscribe to specific life-cycle events of resources filtered by criteria or to changes in search queries.
