Slow build time when exceeding 20 fields in form

[gv-sothebys-ivar]

Hi,

I'm using Re-Formality version 4.0.0.-beta-17 and noticed when exceeding more than 20 fields the build times goes up exponentially. In my project I need up to 50 fields and for that case it just doesn't even build.

I created a fresh project to test this, I only have one file implementing a simple form hook and added 20 fields to input, output and validate. I then added one field at a time to see the build time of the test project was growing and this was the result when reaching 25 fields:

Any idea why this is happening? I have used formality from earlier versions from you guys and I haven't had any problem with large forms before 🤔

I have added the test project as a zip so you can test this out for yourself re-formality-test.zip

Hi @gv-sothebys-ivar, thanks for the report. The earlier version was implemented without involving code generation, and the current one is a ppx.

That's unfortunate, but I won't be able to invest in this issue right now. Mainly due to being busy with relocation and the uncertainty of the future of PPXs in ReScript.

Let's review this in a couple of months.

We've also had to skip this library due to the PPX taking too long to do code gen.
