createResolver

createResolver(fields, fieldOverrides?): Resolver<FieldValues>

Defined in: packages/forms/src/resolver.ts:81

Create a react-hook-form resolver that validates form values against introspected FieldDefinition rules.

Checks required fields, string length constraints, numeric range constraints, regex patterns, and any custom validate functions from FieldConfig overrides. Schema-derived rules (from introspectTable) and custom rules (from v) are both enforced.

Parameters

fields

FieldDefinition[]

The FieldDefinition array to validate against (from introspectTable).

fieldOverrides?

Partial<Record<string, FieldConfig>>

Optional per-field FieldConfig overrides, including custom validate functions.

Returns

Resolver<FieldValues>

A react-hook-form Resolver that validates form values and returns errors.

Example

import { introspectTable, createResolver } from "@cfast/forms";
import { posts } from "./schema";
import { useForm } from "react-hook-form";

const fields = introspectTable(posts);
const resolver = createResolver(fields, {
  title: { validate: (v) => (v === "test" ? "No test titles" : undefined) },
});
const form = useForm({ resolver });
