Feat: Deploy AWS Lambda Function with URL

[nelsonic]

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 😬

But I'm burning the candle at both ends working at 3am ... so calling it a day. 🛌

Basic lambda function is working:

Working! 🎉

Not sharing the URL just yet as want to avoid spam. But I'm optimistic this will work. 💭

[nelsonic]

This is already what I needed ...

Now I need to use it ... 💭
