Enabling VINEJS schema validation

@vinejs/vine is a schema validation library with synchronous rules and an async validation API.

@vinejs/vine is not included in the package, so you have to install it manually.

npm install --save @vinejs/vine

Define the VineJS schema

import { Vine } from '@vinejs/vine';

const vine = new Vine();

const $schema = vine.object({
  email: vine.string().email(),
  age: vine.number().min(18),
  user: vine.object({
    zip: vine.string().minLength(5),
  }),
});

Define a plugins object

VINEJS requires the package prop (a Vine instance) together with the previously defined schema. The schema is compiled by the driver.

import vinejs from 'mobx-formkit/lib/validators/VINEJS';

const plugins = {
  vinejs: vinejs({
    package: vine, // Vine instance
    schema: $schema,
  })
};

Create the form passing the plugins object

new Form({ ... }, { plugins });

Async (promise-based) validation

VineJS validate() is async-by-design at the API level — even for synchronous rules. The driver consumes the mobx-formkit async contract (setValidationAsyncData + promises), so always await validation:

await form.validate();
await form.submit();

Errors are matched per-path from VineJS error.messages (dot-notation paths like user.zip), so nested field errors land on the correct field automatically.

Note: VINEJS supports the extend callback ({ validator, form }). For custom rules use VineJS .rule() / .refine() on the schema directly.
