An AWS lambda that generates PDF files from HTML using pdfkit and wkhtmltopdf.

This package will:

• Read context variables from the API payload.
• Render context varialbes with the vendor/templates/base.html.
• Pass the rendered HTML to wkhtmltopdf to generate the PDF
• Upload the PDF file to S3.
• Return a signed URL of the PDF and the key.

This package is not feature complete. It is intended to be the starting point for a PDF generator as the HTML template will need to be coded, the context variables handled and authentication added.

Chalice microframework is used to do the aws configuration heavylifting.
