mobx-react-hook-form

Simple react-hook-form wrapper for MobX.

Usage

import { reaction } from "mobx";
import { observer } from "mobx-react-lite";
import { Form } from "mobx-react-hook-form";

const form = new Form({
  resolver: valibotResolver(
    v.object({
      username: v.string('This field is required')
    })
  ),
  onSubmit: ({ username }) => {
    console.info("nick username", username);
  },
  onSubmitFailed: () => {
    //
  },
  onReset: () => {
    //
  }
})


const YourView = observer(() => {
  return (
    <form onSubmit={form.submit} onReset={form.reset}>
      <Controller control={form.control} name={'username'} render={...} />
    </form>
  )
})

API

This library uses createFormControl.
So API is almost identical with result of createFormControl function call.

Differences:

• reset method renamed to resetForm

Additional API

changeField(name, value, opts)

The same as setValue, but will trigger validation if form was submitted
Also you can pass undefined as value to remove value
It should work the same as field.onChange from react-hook-form's Controller

Example:

// Update a single field
changeField("name", "value");

/** form submitted **/

changeField("name", "value"); // will call setValue('name', 'value', { shouldValidate: true })

changeField("name", undefined); // removes value

submit()

This method is needed to pass into <form /> as onSubmit prop, or you can call this method if you want to submit form

Example:

const form = new Form();

const Component = () => {
  return (
    <form onSubmit={form.submit} onReset={form.reset}>
      ...
    </form>
  );
};

reset()

This method is needed to pass into <form /> as onReset prop, or you can call this method if you want to reset form

Example:

const form = new Form();

const Component = () => {
  return (
    <form onSubmit={form.submit} onReset={form.reset}>
      ...
    </form>
  );
};
