Build Alexa Skills in Go using AWS Lambda

How it works

See example/main.go

How to upload your code to AWS using Lambda

Build a binary that runs on Linux and zip it up into a deployment package.

$ GOOS=linux go build -o lambda_handler main.go
$ zip deployment.zip lambda_handler

Assuming you have already installed aws-cli:

NOTE:
function-name: name which handles the requests (in our example it is alexaDispatchIntentHandler)
handler: name of the binary file (here it is lambda_handler)
region: in order to run Alexa Skills with AWS Lambda you need to choose us-west-1, us-east-1 or eu-west-1

$ aws lambda create-function \
  --region eu-west-1 \
  --function-name alexaDispatchIntentHandler \
  --memory 128 \
  --role arn:aws:iam::<account-id>:role/<role> \
  --runtime go1.x \
  --zip-file fileb://deployment.zip \
  --handler lambda_handler

Verify if your function was uploaded:

1. Open your function you've uploaded
2. Add trigger "Alexa Skills Kit"
3. Add the Alexa Skill ID from Amazon Developer Console
4. Save your changes

Besides that, of course you need to add and configure the Alexa Skill in the Amazon Developer Console.
