Setup

1. Install Claudia.js

2. npm install

3. Create a DynamoDB table in AWS:

   aws dynamodb create-table --table-name RouteCounts \
     --attribute-definitions AttributeName=id,AttributeType=S \
     --key-schema AttributeName=id,KeyType=HASH \
     --provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1 \
     --region us-east-1 \
     --query TableDescription.TableArn --output text
   

4. Create a Lambda in AWS, using the start script:

   npm run start
   

5. Deploy the function code:

   claudia update
   

6. Claudia will print the API Gateway URL. Set an environment variable and curl a few routes:

   $ export BASE=https://waa2p41ame.execute-api.us-east-1.amazonaws.com/latest
   
   $ curl $BASE/foo
   {"id":"foo","count":1}
   
   $ curl $BASE/foo
   {"id":"foo","count":2}    
   
   $ curl $BASE/bar
   {"id":"bar","count":1}    

Cleanup

1. Delete the Lambda function and API Gateway resource:

   claudia destroy
   

2. Delete the Dynamo table:

   aws dynamodb delete-table --table-name RouteCounts --region us-east-1
