< form class = " formly " role = " form " novalidate [ formGroup ]= " form " ( ngSubmit )= " submit(user) " >
< formly-form [ model ]= " user " [ fields ]= " userFields " >
< button type = " submit " class = " btn btn-default " > Button </ button >
</ formly-form >
</ form >
and in your TypeScript file define the the model and fields attributes
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 : ' 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
} ;
npm install ng2-formly --save
add the script to the HTML file (if necessary)
< 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.
