    Automagically manage React forms state and automatic validation with MobX

    Quick Start

    npm install --save mobx-react-form

    Choose and Setup a Validation Plugin

    See Validation Plugins & Modes and Supported Validation Packages for more info.

    Below we are creating a plugins object using the validatorjs package to enable DVR functionalities (Declarative Validation Rules).

    import validatorjs from 'validatorjs';
    const plugins = { dvr: validatorjs };

    Define the Form Fields

    Define the fields as a collection with a rules property for the validation.

    const fields = [{
      name: 'email',
      label: 'Email',
      placeholder: 'Insert Email',
      rules: 'required|email|string|between:5,25',
    }, {
      name: 'password',
      label: 'Password',
      placeholder: 'Insert Password',
      rules: 'required|string|between:5,25',
    }, {
      name: 'passwordConfirm',
      label: 'Password Confirmation',
      placeholder: 'Confirm Password',
      rules: 'required|string|same:password',

    You can also define fields as an object.

    Define the Validation Hooks

    const hooks = {
      onSuccess(form) {
        alert('Form is valid! Send the request here.');
        // get field values
        console.log('Form Values!', form.values());
      onError(form) {
        alert('Form has errors!');
        // get all form errors
        console.log('All form errors', form.errors());

    Initialize the Form

    Simply pass the fields, plugins and hooks objects to the constructor

    import MobxReactForm from 'mobx-react-form';
    const form = new MobxReactForm({ fields }, { plugins, hooks });

    Pass the form to a react component

    The package provide some built-in and ready to use Event Handlers:

    onSubmit(e), onClear(e), onReset(e) & more...

    import React from 'react';
    import { observer } from 'mobx-react';
    export default observer(({ form }) => (
      <form onSubmit={form.onSubmit}>
        <label htmlFor={form.$('username').id}>
        <input {...form.$('username').bind()} />
        {/* ... other inputs ... */}
        <button type="submit" onClick={form.onSubmit}>Submit</button>
        <button type="button" onClick={form.onClear}>Clear</button>
        <button type="button" onClick={form.onReset}>Reset</button>

    Other Field Props are available. See the docs for more details.
