npm install --save mobx-react-form
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 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.
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
Simply pass the fields
, plugins
and hooks
objects to the constructor
import MobxReactForm from 'mobx-react-form';
const myForm = new MobxReactForm({ fields }, { plugins, hooks });

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>
));
