We need a way of invoking the scraper from our Elixir app for dwyl/who#86

Todo

• allow a single url variable
• return data as JSON

Note: Only working on the "happy path".

• deploy to lambda using https://github.com/dwyl/aws-lambda-deploy
  • Update https://github.com/dwyl/aws-lambda-deploy in the process 😬
