Serverless example

The Serverless Framework supports provided runtimes for AWS Lambda.

This example shows how to easily deploy a small ClojureScript webservice with the Lumo custom runtime.

Usage

Make sure you have AWS credentials adequate for deploying with Serverless (a root user will certainly do!), and simply issue the following:

$ npm install serverless # install the framework as a node module
$ npx serverless deploy # package and deploy to AWS

Serverless should do its magic and create a Lambda function and an API Gateway, and return an overview of the GET endpoint:

...
endpoints:
  GET - https://abc123.execute-api.eu-west-1.amazonaws.com/dev/hello
functions:
  hello: runtime-provided-test-dev-hello
...

Now, try doing a cURL against the url. You should get some EDN back:

$ curl https://abc123.execute-api.eu-west-1.amazonaws.com/dev/hello

{:hello "Hello from my-handler!", :input {:event {"resource" "/hello", "body" nil, ...

That's pretty much it!
