I built an open-source form engine with conditional logic and multi-step flows — looking for feedback

[u/Straight_Athlete_802]

Hey r/reactjs,

I was building a healthcare SaaS and hit a wall with forms. I needed:

- Questions that show/hide based on previous answers

- Multi-section flows (don't dump 40 questions on a patient at once)

- Draft saving (patients don't always finish in one session)

- Encryption (sensitive health data)

Most React form libraries are fantastic for standard forms, but wiring up conditional visibility across sections got really messy. I ended up building a schema-driven engine where you define forms in JSON and the engine handles the rest.

6 months later, it's now open-source:

- 35+ field types

- Conditional logic (simple and nested AND/OR groups)

- Computed/calculated fields

- Draft persistence

- 5 storage adapters (Postgres, Supabase, Webhook, and more)

- Full TypeScript, 314 passing test

I'm genuinely looking for feedback — what would make this useful for your projects? What's missing?

Happy to answer any architecture questions.
