Automagically manage React forms state and automatic validation with MobX
npm install --save mobx-react-formSee 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 fields as a collection with a rules property for the validation.
const fields = [{
name: 'email',
label: 'Email',
rules: 'required|email|string|between:5,25',
}, {
name: 'password',
label: 'Password',
rules: 'required|string|between:5,25',
}];You can also define
fieldsas anobject.
import MobxReactForm from 'mobx-react-form';
class MyForm extends MobxReactForm {
onSuccess(form) {
alert('Form is valid! Send the request here.');
// get field values
console.log('Form Values!', form.values());
}
onError(form) {
// get all form errors
console.log('All form errors', form.errors());
// invalidate the form with a custom error message
form.invalidate('This is a generic error message!');
}
}The Events Handler can be decoupled from the class as well.
Simply pass the fields and plugins objects to the constructor
export default new MyForm({ fields, plugins });The package provide those built-in and ready to use Event Handlers:
onSubmit(e), onSuccess(e), onError(e).
import React from 'react';
import { observer } from 'mobx-react';
const FormComponent = ({ form, events }) => (
<form onSubmit={form.onSubmit}>
<input
type="text"
name={form.$('username').name}
value={form.$('username').value}
placeholder={form.$('username').label}
onChange={form.$('username').sync}
/>
<p>{form.$('username').error}</p>
...
<button type="submit" onClick={form.onSubmit}>Submit</button>
<button type="button" onClick={form.onClear}>Clear</button>
<button type="button" onClick={form.onReset}>Reset</button>
<p>{form.error}</p>
</form>
);
export default observer(FormComponent);If you want to contribute to the development, do not hesitate to fork the repo and send pull requests.
