rrule VS pdf-lib

Know the standards! I was making an app that lets you schedule repeatable tasks and had trouble implementing the logic to calculate the "second Tuesday of the month" reliably. Then I found RFC 5545 and rrule.js and it made it trivial.

So we decided to go with RRule, which as the lib itself says:

All best with your project

As I already have React-big-calendar, another option would be to show a customized version for the workdays where the events would be the classes. But in this case each subject would have recurring events and React-big-calendar does not support recurring events natively so I would have to get it done with some help (I have ready about rrule)

I didn't personally work on the time zone code, but I know we're leveraging the JS library date-fns for most of our date logic and RRule for recurrence logic.

Besides, there are rrule.js mentioned above, which cover the 2 requirements

writePdf: used for writing the final completed PDF after receiving the response from the Claude 3 Opus API, this uses the PDF-lib library to manipulate and modify the final file.

I'm facing that same pain point of programmatic PDF filling. I noodled around in the PDF format and learned it's a bit difficult to deal with fonts and formatting. But I think this client-side library works well enough, as a start: https://pdf-lib.js.org/#:~:text=a%20single%20document.-,Fill...

I've also heard of one paid API that I forgot but seemed to work well, and this related service https://www.jotform.com/, and I also considered porting some server-side libraries to WASM. One day I'll collect all the libraries and findings in a blog post.

Are you looking to programmatically fill any PDF form by detecting the fields? Or are you filling one known PDF template?

Thanks! For PDF form filling, I use the APIs that pdf-lib [0] exposes. That includes text fields, checkboxes, radio buttons, dropdowns and options lists. Give it a try and let me know if you find a type of form field that's missing.

I do not know if some plugin exists, but maybe you have to take a look at https://pdf-lib.js.org/

PDFmake or pdf-lib would be the way to go in my opinion.

Sure! You can build your own PDF editor with a combination of PDF.js and PDF-lib

I stand on the shoulders of giants, namely PDF-lib, PDF-js and React-beautiful-DND – everything else is pretty much custom code.

How one can use a library such as PDF-Lib (npm, website) that:
