PdfLambda is a simple AWS Lambda function that converts HTML to PDF using wkhtmltopdf.
Moreover, it's possible to use it for merging multiple PDFs into one.
Very simple and straight forward npx --package @sladg/pdf-lambda cli deploy. Pass --help in the end for all options and configuration.
In case you want to clean it up, use npx --package @sladg/pdf-lambda cli remove.
Command will output "Rest API URL" that you can use to make requests.
GET / - simple check to see options and configuration.
POST /pdf/merge-multiple - merge multiple PDFs into one
POST /pdf/convert-from-html - convert HTML to PDF
Make sure to set Accept: application/pdf in request headers.
Does not support var(--color) CSS properties due to wkhtmltopdf limitations.
Generally the CSS and HTML should be as simple as possible, it's not as powerful as Chrome or Firefox, but it's way faster and smaller, resulting in small & efficient solution.
