      key: 'email',
      type: 'input',

  npm install ng2-formly --save

• add the script to the HTML file (if necessary)

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

• and to your component add

import {Component} from '@angular/core';
import {bootstrap} from '@angular/platform/browser';
import {FormlyForm, FormlyConfig, FormlyMessages, TemplateDirectives, FormlyProviders} from '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.
