angular2-formly is an Angular 2 module which has a Components to help customize and render JavaScript/JSON configured forms. The formly-form Component and the FormlyConfig service are very powerful and bring unmatched maintainability to your application's forms.

This is still a serious WIP.

Include the FormlyForm in the directives attribute of you Component and put this in your template

<formly-form [model]="user" [fields]="userFields">
    <button type="submit" class="btn btn-default" (click)="submit(user)">Button</button>
</formly-form>

and in your TypeScript file define the the model and fields attrnbutes

this.userFields = [{
  className: 'row',
  fieldGroup: [{
      className: 'col-xs-6',
      key: 'email',
      type: 'input',
      templateOptions: {
          type: 'email',
          label: 'Email address',
          placeholder: 'Enter email'
      },
      validation: Validators.compose([Validators.required, ValidationService.emailValidator])
  }, {
      className: 'col-xs-6',
      key: 'password',
      type: 'input',
      templateOptions: {
          type: 'password',
          label: 'Password',
          placeholder: 'Password',
          pattern: ''
      },
      validation: Validators.compose([Validators.required, Validators.maxLength(10), Validators.minLength(2)])
  }]
}];

this.user = {
  email: 'email@gmail.com',
  checked: false
};
            

Quick Start

• install ng2-formly

  npm install ng2-formly --save

• add the script to the HTML file

<!-- index.html -->
<script src="node_modules/ng2-formly/bundles/ng2-formly.min.js"></script>

• and to your component add

import {Component} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';
import {FormlyForm, FormlyConfig, FormlyMessages, TemplateDirectives, FormlyProviders} from 'ng2-formly/ng2-formly'

@Component({
    selector: 'hello-app',
    template: `
        <h1>Hello, {{name}}!</h1>
        Say hello to: <input [value]="name" (input)="name = $event.target.value">
        <formly-form [model]="user" [fields]="userFields"></formly-form>
    `,
    directives: [FormlyForm],
    providers: [FormlyConfig, FormlyMessages]
})
export class HelloApp {
    name: string = 'World';
    user = {};
    userFields;
    constructor(fc: FormlyConfig) {
        ['input', 'checkbox'].forEach((field) => {
            fc.setType({
                name: field,
                component: TemplateDirectives[field]
            })
        });
        
        this.userFields = [{
            key: 'nameOfPerson',
            type: 'input',
            templateOptions: {}
        }]
    }
}

bootstrap(HelloApp, [FormlyProviders]);

From there, it's just JavaScript. Allowing for DRY, maintainable, reusable forms.
