Deploy the Sample Code

To deploy the sample code, it must first be packaged and then uploaded to the AWS Lambda as the function code.

Package the Sample Code

  1. In your working directory, browse to the skill-sample-nodejs-smarthome-switch/lambda/smarthome directory.
  2. In that directory and from the command-line, run the following command to install the dependencies: npm install.
  3. Zip the contents of the skill-sample-nodejs-smarthome-switch/lambda/smarthome directory into a file named package.zip and save it to the working-smarthome folder. Make sure that the index.js file, alexa/ folder, and node_modules/ folder are at the root of the zip file. Do not include the full skill-sample-nodejs-smarthome-switch/lambda/smarthome path structure.

If you encounter any issues, refer to the AWS Documentation for Creating a Deployment Package (Node.js).

Upload the Sample Code

  1. Navigate to https://us-east-1.console.aws.amazon.com/lambda/home?region=us-east-1#/functions/skill-sample-nodejs-smarthome-switch?tab=graph and locate the Function code section.
  2. In the code entry type dropdown, select Upload a .ZIP file.
  3. Click the Upload button and browser to the working-smarthome directory or where you zipped the packaged code.
  4. Select the package.zip file to upload as the lambda function code.
  5. Click Save at the top right of the page. If successful, the environment of the Function code section will update replacing the previous contents.

Test the Lambda Function

After the sample code is uploaded to the Lambda function, you can test that it is properly working via the test events functionality of the AWS Lambda console. This is done by creating a Test Event that contains a sample directive message that the function code should handle and respond to.

Create a Discovery Test Event

  1. On the function page for skill-sample-nodejs-smarthome-switch, select the Select a test event.. dropdown from the top menu of the function and click Configure test events.
  2. In the dialog that opens, leave Create new test event selected and leave the default template.
  3. For the Event name enter: directiveDiscovery.
  4. Copy and paste the contents of https://raw.githubusercontent.com/alexa/alexa-smarthome/master/sample_messages/Discovery/Discovery.request.json into the text field at the bottom of the dialog replacing its contents.
  5. Click Create.

Run a Discovery Test Event

  1. With the directiveDiscovery Test Event created and selected in the dropdown, click the Test button.
  2. If everything was successful, an "Execution result: succeeded" message will be returned and clicking on the Details link of the result should show a response that looks like the following:

Any errors with the code or packaging and deployment of the code will be reflected in the result response. Not that on a successful response, the event namespace is Alexa.Discovery. This is because the code is responding to a test event that sends in a Discovery directive.
