Json Schema with Form

[gam-phon]

Hello,

Since you build the form and render it as well. How about there is one API for build Form or API based on Json Schema, so validation could be on client and server as well and validation will be declarative. Also there will be an API documentation for your API or Form.

Checkout fastify

Schema based: even if it is not mandatory we recommend to use JSON Schema to validate your routes and serialize your outputs, internally Fastify compiles the schema in a highly performant function.

This react-jsonschema-form takes json schema and render it as form, maybe use this as base line.

There will be automatic documentation, validation in client and server, and declarative way to creating forms, based on standard

Also in Python

https://pydantic-docs.helpmanual.io/ with https://fastapi.tiangolo.com/ is a great example.

Standards-based: Based on (and fully compatible with) the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema.
