A small library that adds validation with decorators and build angular forms 🅰📝

## Demo

Try out our [demo on Stackblitz](https://ngx-forms-builder-example.stackblitz.io)!

## Install

```bash

npm install ngx-forms-builder --save

```

  

## Setup

You'll need to add `NgxFormsBuilderModule` to your application module. So that, the builder service will be accessible in your application.

```typescript

@NgModule({

  declarations: [

    YourAppComponent

  ],

  imports: [

    NgxFormsBuilderModule.forRoot(),

    ...

  ],

  providers: [],

  bootstrap: [YourAppComponent]

})

export class YourAppComponent {}

```

## Usage

```typescript

import { Required, Email, Pattern, Min, Max, CustomValidator } from 'ngx-forms-builder';

export class Person {

  @Required()

  firstName: string;

  @Required()

  lastName: string;

  @Email()

  @Required()

  email: string;

  @Pattern(/^[.,_A-zÀ-ú0-9]*((-|\s)*[.,_A-zÀ-ú0-9])*$/)

  address: string;

  @Min(1)

  @Max(100)

  age: number;

  @Exclude()

  secretPassword: string;

  @CustomValidator(identificationValidator)

  documentNumber: string;

  constructor(firstName: string, lastName: string, email: string, age: number, address: string, secretPassword: string) {

    this.firstName = firstName;

    this.lastName = lastName;

    this.email = email;

    this.age = age;

    this.address = address;

    this.secretPassword = secretPassword;

  }

}

/*-------------------------------------------------------------*/

import { Component, OnInit } from '@angular/core';

import { FormGroup } from '@angular/forms';

import { ModelFormBuilder } from 'ngx-forms-builder';

import { Person } from './person';

import { MatSnackBar } from '@angular/material/snack-bar';

@Component({

  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css']

})

export class AppComponent implements OnInit {

  formGroup: FormGroup;

  constructor(private fb: ModelFormBuilder, private snackBar: MatSnackBar) { }

  ngOnInit() {

    const model = new Person('Raymond', 'Coplin', '[email protected]', 23, 'Wall Street, New York', '');

    this.formGroup = this.fb.build(model);

  }

  onSubmit() {

    this.snackBar.open(`${this.formGroup.get('firstName').value} ${this.formGroup.get('lastName').value}`, 'Saved', {

      duration: 2000,

    });

  }

}
