@lesto/forms

Schema-driven forms on @lesto/ui — one spec renders the form and validates the submission.

Part of Lesto, the batteries-included, agent-native fullstack framework.

bun add @lesto/forms

import { createFormRegistry, renderForm, validateSubmission, type FormSpec } from "@lesto/forms";

const spec: FormSpec = {
  action: "/signup",
  fields: [
    { name: "email", type: "email", required: true },
    { name: "age", type: "number" },
  ],
};

const tree = renderForm(spec);                              // a @lesto/ui node tree
const { valid, errors } = validateSubmission(spec, body);  // built-in validator → per-field errors

Ships its own form components — it uses @lesto/ui's engine and types (not shadcn/zod), and the built-in validator returns per-field errors you render inline on a 422.
