Boilerplate for remote skill

Authentication

Skill can authenticate incoming converse requests.

BY default - the skill will respond to any incoming converse request. By default it will not authenticate incoming converse requests to make sure that they are coming from a core that this skill is registered to. in order to enable such authentication, change the parameter AUTHENTICATE_REQUESTS to true in the '.env' configuration file

After enabling the authentication, all incoming calls to the skill will be authenticated using a key. The key is generated by the core when the skill is registered to the core, the key should be stored in the keys.txt file found in res/assets/keys.txt.

A key is also used in order to access the skill swagger page, in order to get access just add one of the keys in your key.txt file to the header (you can also create a new key).

Skill Version

If an skill is going to be published, it should start at 1.0.0, though it is not mandatory.

After this, changes should be handled as follows:

(PATCH) Bug fixes and other minor changes: Patch release, increment the last number, e.g. 1.0.1
(MINOR) New features which don't break existing features: Minor release, increment the middle number, e.g. 1.1.0
(MAJOR) Changes which break backwards compatibility: Major release, increment the first number, e.g. 2.0.0

See Semantic Versioning for more information.

API Reference

Method	API	Description
GET	/v1/api/manifest	Returns the skill manifest as a JSON object.
GET	/v1/api/nlu	Returns NLU metadata which is used by the interact core NLU engines.
GET	/v1/api/intents	Returns skill intents descriptors.
GET	/v1/api/healthCheck	Check the status (health) of the skill.
POST	/v1/api/converse	Get a response from user input or event.

NLU

The Natural Language Understanding includes data required by the Interact core to extract intents and entities.

Intents Descriptors

The intents file is optional metadata file which includes skill intent descriptors. The information in this file is applied by the core to extracted intent (after NLU extraction phase). The skill developer can use the intents descriptors to increase the accuracy of the skill and to control intent behavior.

{
  "<intent name>" :
  {
    "visibility" : "string",
    "entities" : [
      {
        "name" : "string",
        "required" : "boolean"
      }
    ]
  }
}

Parameter	Description	Type	Required
visibility	Can be use to hide or show intent to core	string	No

Running

Locally

To run skill locally you can use the following command

npm start

Note! Make sure the port is not used by any other skill / server as the skill will not start.

Docker

Prerequisites

Install Docker

Locally

Build the image

docker build -t skill-boileplate:local .

Create and run a container

docker run --name fun -p 3000:3000 -e PORT=3000 -it skill-boileplate:local

Bluemix

For more information how to build and run containers in Bluemix you can refer to Adding Docker images to your organization's private Bluemix images registry

Build your image and push it to your private Bluemix registry.

bx ic build -t registry.ng.bluemix.net/<namespace>/skill-boileplate:v1.0.0 .

Tip: Run bx ic namespace get to retrieve your namespace information.

Create a container from your image.

bx ic create --name skill-boileplate -p 3001:3001 -e PORT=3001 registry.ng.bluemix.net/<namespace>/skill-boileplate:v1.0.0

Note: Select port that will not conflict with other skill

If can be published as public skill, bind a public IP address to your container.

bx ic bind <ip address> <container ID>

Tip: You can see your public IP addresses by running bx ic ips. To request a new one, run bx ic ip request.

How To Manually Test Skill

The skill (locally or hosted) can be tested directly with the skill converse REST API. Use the following json block in the skill swagger page.

{
  "id": "001",
  "text": "hello world",
  "retext": "hello world",
  "version": "1.0",
  "language": "en-US",
  "attributes": {
    "intent": "hello-world"
  },
  "context": {
    "user": {
      "id": "user-001"
    },
    "application": {
      "id": "app-001",
      "attributes": {
      }
    },
    "session": {
      "new": true,
      "attributes": {
      },
      "version": "1.0"
    }
  }
}
