## Quick Start
[](https://codesandbox.io/s/nrrZgG8y4)
```bash
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).
```javascript
import dvr from 'mobx-react-form/lib/validators/DVR';
import validatorjs from 'validatorjs';
const plugins = {
dvr: dvr({
package: validatorjs
})
};
```
> See [Validation Plugins](https://foxhound87.github.io/mobx-react-form/docs/validation/plugins.html) for more info on supported packages.
#### Define the Form Fields
Define the `fields` as a collection with a `rules` property for the validation.
```javascript
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](https://foxhound87.github.io/mobx-react-form/docs/fields/) and all available [Field Props](https://foxhound87.github.io/mobx-react-form/docs/api-reference/fields-properties.html) on the docs.
#### Define the Validation Hooks
```javascript
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](https://foxhound87.github.io/mobx-react-form/docs/events/validation-hooks.html) and the [Event Hooks](https://foxhound87.github.io/mobx-react-form/docs/events/event-hooks.html)
#### Initialize the Form
Simply pass the `fields`, `plugins` and `hooks` objects to the constructor
```javascript
import MobxReactForm from 'mobx-react-form';
const myForm = new MobxReactForm({ fields }, { plugins, hooks });
```
> Learn more on the docs about the [Form Instance](https://foxhound87.github.io/mobx-react-form/docs/form/) and the [Form Options](https://foxhound87.github.io/mobx-react-form/docs/form/form-options.html)
#### 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...](https://foxhound87.github.io/mobx-react-form/docs/events/event-handlers.html)
```javascript
import React from 'react';
import { observer } from 'mobx-react';
export default observer(({ myForm }) => (
));
```
