Running the project

Pre-requisites

• Node.js
• Register for an AWS Account
• Register for an Amazon Developer Account
• Install and Setup ASK CLI

Installation

• Install the dependencies

$ 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

Local development

In order to develop locally and see your changes reflected instantly, you will need to create an SSH tunnel or expose somehow your local development server. There are several services that allow you to do this, for example ngrok or serveo.net.

Using servo.net

This is the easiest to setup

1. You need to have an SSH client installed, then simply run

$ ssh -R 80:localhost:3980 serveo.net
Forwarding HTTP traffic from [https://YOUR_URL]
Press g to start a GUI session and ctrl-c to quit.

2. Once you see the URL, copy it and go to your Skill console.

3. Open the Endpoint menu and select HTTPS

4. Under Default Region paste the previous URL you copied.

5. On the select box choose: My development endpoint is a sub-domain of a domain that has a wildcard certificate from a certificate authority.

6. You are done! Just run npm start to start the local server and begin testing the skill.

Using ngrok.io

1. Install ngrok

2. Run ngrok http 3980

3. Copy the URL and follow the same steps above from 3 to 6.

Developer tasks

Command	Description
clean	Deletes the dist folder
build	Builds the lambda function and exports it to the dist folder
deploy	Builds the lambda function and deploys EVERYTHING (skill, model, lambda)
deploy:lambda	Builds the lambda function and deploys it (just the lambda function)
deploy:local	Deploys the skill details for the local profile, which will update the HTTPS endpoint
start	Starts the local express server using nodemon for local development

To see the actual commands, check package.json.

Also check the ASK CLI Command Reference for more details on using the ASK CLI.

Testing

The project contains automated tests using jest.

$ npm run test

Taken from the official hello world project.

1. To test, you need to login to Alexa Developer Console, and enable the "Test" switch on your skill from the "Test" Tab.

2. Simulate verbal interaction with your skill through the command line (this might take a few moments) using the following example:

    $ ask simulate -l en-US -t "open greeter"
   
    ✓ 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 hello world
   

Customization

Taken from the official hello world project.

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 (e.g. en-US, en-GB, de-DE, etc.)

   See the Skill Manifest Documentation for more information.

2. ./lambda/custom/index.ts

   Modify messages, and data 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.

   $ ask deploy
