rjsf-formulasComputed fields for RJSF

Embed formula-driven computed fields directly in your JSON schema. Works with any expression language.

Schema-driven

Mark fields as computed directly in your JSON schema using a custom key. No extra configuration needed.

Bring your own expression language. Supply an evaluator function — synchronous or async — and rjsf-formulas handles the rest.

Async evaluators are fully supported, with debouncing, loading state tracking, and stale-result suppression built in.
