jsonapi-home

An implementation of an experimental JSON:API-Home specification, which is a combination of the JSONHome and json:api.

Using

To start lets mount the engine:

Rails.application.routes.draw do
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html

  mount JSONAPI::Home::Engine, at: "/"

  namespace :v1 do
    resources :accounts
  end

  root to: "pages#landing"
end

This will setup the basic set of home routes and with the following request:

* Preparing request to http://localhost:3000/v1/jsonapi-home-resources
* Using libcurl/7.54.0 SecureTransport zlib/1.2.8
* Enable automatic URL encoding
* Enable SSL validation
* Enable cookie sending with jar of 0 cookies
* Connection 68 seems to be dead!
* Closing connection 68
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 3000 (#69)

You'll get this payload:

{
  "data": [
    {
      "type": "jsonapi-home-resources",
      "id": "jsonapi-home-resources-v1-index",
      "attributes": {

        "verb": "GET",

        "mediatype": "application/vnd.api+json",
        "created-at": "2018-03-25T16:07:03.039-07:00",

      },
      "jsonapi": {
        "version": "1.0"
      }
    },
    {
      "type": "jsonapi-home-resources",
      "id": "jsonapi-home-resources-v1-show",
      "attributes": {
        "namespace": "jsonapi-home-resources",
        "version": "v1",
        "intent": "show",
        "description": "All discoverable HTTP JSON:API endpoints that this server knows about",
        "verb": "GET",
        "href": "/v1/jsonapi-home-resources/{id}",
        "mediatype": "application/vnd.api+json",
        "created-at": "2018-03-25T16:07:03.039-07:00",
        "updated-at": "2018-03-25T16:07:05.003-07:00"
      },
      "links": {
        "self": "/jsonapi-home-resources/jsonapi-home-resources-v1-show"
      },
      "jsonapi": {
        "version": "1.0"
      }
    }
  ],
  "jsonapi": {
    "version": "1.0"
  },
  "meta": {
    "endpoint": {
      "version": "1"
    }
  }
}

You'll notice that we only show our own home routes, we're self-referential! Now we've got to setup your other endpoints:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts"
    )

    def index
      # ...
    end

    def show
      # ...
    end

    def create
      # ...
    end

    def update
      # ...
    end

    def destroy
      # ...
    end
  end
end

Which results in this payload:

Because it's jsonapi.org you can use all the normal interfaces.

Custom URL Location

By default you will see resources have a root url of whatever returns from root_path.

If you need a different value you can do one of two things:

You can set up a HOME_LOCATION ENV variable which is a protocol+hostname[+suffix] combination where your endpoints exist:

HOME_LOCATION=https://origin.example.com

If you need an individual endpoint to have this value, try:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      location: "http://special.example.com"
    )
  end
end

Custom Description

If you want you can overwrite the description that comes with every endpoint to provide context:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      description: "The accounts resource is being removed on the 5th of march"
    )
  end
end

Deprecated

To provide a hint to clients you can also set the entire endpoint as deprecated:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      deprecated: true,
    )
  end
end

Or specific endpoints:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      deprecated: {
        index: true
      },
    )
  end
end

Documentation href

Every endpoint can link to the human documentation for that endpoint:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      documentation: "https://documentation.example.com"
    )
  end
end

json:api Version

Finally you can specify the specific version of JSON:API this endpoint uses:

module V1
  class AccountsController < V1::ApplicationController
    discoverable(
      version: "v1",
      namespace: "accounts",
      jsonapi_version: "1.1"
    )
  end
end

Of course, these are all just descriptive. jsonapi-home does not enforce these configurations.

Installing

Run this command:

$ bundle add jsonapi-home
