yes, I started with something very niche and specific, but my plan is to extend this into composing / generating the PDF from scratch.
What components would you need for your documents?
I am running on python and AWS Lambda. Works really smooth battle tested it with 100 pdf pages and 400 fields to be merged and the Pdf is generated within 2 seconds.
And I am currently using one of the lowest resource settings on AWS Lambda.
I am mostly using pikepdf and the a lot of secret sauce added ;)
Yes I still have problems with the activation mail. Need to fix this, currently rely on my own SMTP which is not a good idea. Should move to a service.
The main use case is that you have a document from a third party provider, e.g. bank, government office, etc. which needs to be pre-filled with your data.
My current (financial sector) and my previous employer (energy industry) use such a solution and the existing solutions are very complicated and also way to expensive, IMHO.
