Features


Quick Start

Edit form-quickstart

npm install --save mobx-react-form

Choose and Setup a Validation Plugin

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

import dvr from 'mobx-react-form/lib/validators/DVR';
import validatorjs from 'validatorjs';

const plugins = {
  dvr: dvr({
    package: validatorjs
  })
};

See Validation Plugins for more info on supported packages.

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',
  type: 'password',
}, {
  name: 'passwordConfirm',
  label: 'Password Confirmation',
  placeholder: 'Confirm Password',
  rules: 'required|string|same:password',
  type: 'password',
}];

See Fields Definitions and all available Field Props on the docs.

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());
  }
}

See more on the docs about the Validation Hooks and the Event Hooks

Initialize the Form

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

import MobxReactForm from 'mobx-react-form';

const myForm = new MobxReactForm({ fields }, { plugins, hooks });

Learn more on the docs about the Form Instance and the Form Options

Pass the myForm 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(({ myForm }) => (
  <form onSubmit={myForm.onSubmit}>
    <label htmlFor={myForm.$('email').id}>
      {myForm.$('email').label}
    </label>
    <input {...myForm.$('email').bind()} />
    <p>{myForm.$('email').error}</p>

    {/* ... other inputs ... */}

    <button type="submit" onClick={myForm.onSubmit}>Submit</button>
    <button type="button" onClick={myForm.onClear}>Clear</button>
    <button type="button" onClick={myForm.onReset}>Reset</button>

    <p>{myForm.error}</p>
  </form>
));
