ASK SDK Local Debug (Node.js)

About

ASK SDK Local Debug is a package which enables you to test your skill code locally against your skill invocations by routing requests to your developer machine. This enables you to verify changes quickly to skill code as you can test without needing to deploy skill code to Lambda.

NOTE: Feature is currently only available to customers in the NA region(https://developer.amazon.com/en-US/docs/alexa/custom-skills/develop-skills-in-multiple-languages.html#h2-multiple-endpoints).

Installation

npm install --save ask-sdk-model@^1.29.0
npm install --save-dev ask-sdk-local-debug

Configuration

USING Alexa SKills toolkit for VS code

The Alexa Skills Toolkit for Visual Studio offer integrated support for local debugging. To get started, please review our technical documentation on how to Test your local Alexa skill using VS Code.

NOTE: If you have existing an ASK CLI profile, you will need to sign in again using the latest version of ASK CLI (>=2.13). Once installed, simply re-run ask configure to re-authorize your profile for local debugging.

USING with other IDEs and Debuggers

• To instantiate a connection to the local debugging service, execute the following from your skill’s lambda directory:

node ./node_modules/ask-sdk-local-debug/dist/LocalDebuggerInvoker.js 
      --accessToken <ACCESS_TOKEN>
      --skillId <SKILL_ID>
      --skillEntryFile <FILE_NAME>
      --handlerName <HANDLER_NAME>
      --region <REGION> # Optional argument. Region defaults to NA.

1. ACCESS_TOKEN:
    1. Install ASK CLI v2
    2. npm install ask-cli@2 -g
    3. Generate the accessToken using ASK CLI
    4. ask util generate-lwa-tokens --scopes alexa::ask:skills:debug
    5. You will be directed to a Login with Amazon page. Sign in and retrieve your ACCESS_TOKEN from the terminal.
2. SKILL_ID: The ID of the skill you are trying to debug. Ensure that the developer account you used to login to obtain the access token has access to this skill.
3. FILE_NAME: The path to your skill code's main file (typically `index.js`). This file or module contains the skill's handler function.
4. HANDLER_NAME: The exported handler method (typically `handler`). For example, please see the [Hello world example](https://github.com/alexa/skill-sample-nodejs-hello-world/blob/master/lambda/custom/index.js#L159).
5. REGION: The region of the developer account. The accepted values are NA(North America), FE(Far East), EU(Europe). Defaults to NA. Instructions on finding out your region can be found [here](https://developer.amazon.com/en-US/docs/alexa/ask-toolkit/vs-code-testing-simulator.html#test).

3. Configure your preferred IDE or other debugging tool to attach to the above process or execute directly from your preferred IDE. For example, in VS Code, this would be included in the launch.json:

{
     "type": "node",
     "request": "launch",
     "name": "Skill Debug",
     "program": "<5. Program>",
     "args": [
          "--accessToken","<ACCESS_TOKEN>",
          "--skillId", "<SKILL_ID>",
          "--skillEntryFile", "<FILE_NAME>",
          "--handlerName" , "<HANDLER_NAME>",
          "--region", "<REGION>" # Optional argument. Region defaults to NA.
      ]
}

Things to note

• Local debugging is only available for a skill’s development stage.
• A connection remains active for **1 hour. **You will need to reinstantiate the connection after 1 hour.
• All Alexa requests for the skill will be routed to your development machine while the connection is active.
• Only one connection session may be active for a given skill ID and developer account.
