Build An Alexa Fact Skill

Setup w/ ASK CLI

About

This readme assumes you have your developer environment ready to go and that you have some familiarity with CLI (Command Line Interface) Tools, AWS, and the ASK Developer Portal. If not, click here for a more detailed walkthrough.

Pre-requisites

Installation

  1. Make sure you are running the latest version of the CLI

    $ npm update -g ask-cli

  2. Clone the repository.

    $ git clone https://github.com/alexa/skill-sample-nodejs-fact/

  3. If it's your first time using it, initialize the ASK CLI by navigating into the repository and running npm command: ask init. Follow the prompts.

    $ cd skill-sample-nodejs-fact
$ ask init

  4. Install npm dependencies by navigating into the /lambda/custom directory and running the npm command: npm install

    $ cd lambda/custom
$ npm install

Deployment

ASK CLI will create the skill and the lambda function for you. The Lambda function will be created in us-east-1 (Northern Virginia) by default.

  1. Navigate to the project's root directory. you should see a file named 'skill.json' there.

  2. Deploy the skill and the lambda function in one step by running the following command:

    $ ask deploy

Testing

  1. To test, the skill needs to be enabled. The ask deploy commands enables the skill be default, however you can manually enable it using the ask api enable-skill command. docs.

    $ ask api enable-skill --skill-id amzn1.ask.skill.00000000-0000-0000-0000-000000000000

  2. Simulate verbal interaction with your skill through the command line (this might take a few moments) using the following example, using the locale of your choice (en-US, en-GB, en-IN, en-CA, en-AU):

     $ ask simulate -l en-GB -t "start space facts"

 ✓ Simulation created for simulation id: 4a7a9ed8-94b2-40c0-b3bd-fb63d9887fa7
◡ Waiting for simulation response{
  "status": "SUCCESSFUL",
  ...

  3. Once the "Test" switch is enabled, your skill can be tested on devices associated with the developer account as well. Speak to Alexa from any enabled device, from your browser at echosim.io, or through your Amazon Mobile App and say :

    Alexa, start space facts

Customization

  1. ./skill.json

    Change the skill name, example phrase, icons, testing instructions etc ...

    Remember than many information are locale-specific and must be changed for each locale (en-GB, en-US, etc.)

    See the Skill Manifest Documentation for more information.

  2. ./lambda/custom/index.js

    Modify messages, and facts from the source code to customize the skill.

  3. ./models/*.json

    Change the model definition to replace the invocation name and the sample phrase for each intent. Repeat the operation for each locale you are planning to support.

  4. Remember to re-deploy your skill and lambda function for your changes to take effect.
