Nomad Form

Very simple form generator written with Angular 12, for Bootstrap 5.

Don't re-invent the wheel, Just re-align It

Project Principles

• A clean & beautiful interface
• Highly configurable and customizable
• Responsive web app accessible from any device on the network

What you can do ?

• Build any kind of form element components. Not just traditional inputs, but anything you want and get that validation for free
• Add validation rules and use them with simple syntax
• Use handlers for different states of your form. Ex. "onSubmit", "onError", "onValid" etc.
• Pass external errors to the form to invalidate elements
• You can dynamically add form elements to your form and they will register/unregister to the form

Installation

First you need to install the npm module:

$ npm install @ngx-nomad-form

This will install all dependencies required for use the package.

Usage

1. Import the NgxNomadFormModule:

Finally, you can use ngx-nomad-form in your Angular project. You have to import NgxNomadFormModule.forRoot() in the root NgModule of your application.

The forRoot static method is a convention that provides and configures services at the same time. Make sure you only call this method in the root module of your application, most of the time called AppModule. This method allows you to configure the NgxNomadFormModule.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NgxNomadFormModule } from '@ngx-nomad-form';

@NgModule({
    imports: [
        BrowserModule,
        NgxNomadFormModule.forRoot()
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

SharedModule

If you use a SharedModule that you import in multiple other feature modules, you can export the NgxNomadFormModule to make sure you don't have to import it in every module.

@NgModule({
    exports: [
        CommonModule,
        NgxNomadFormModule
    ]
})
export class SharedModule { }

Note: Never call a forRoot static method in the SharedModule. You might end up with different instances of the service in your injector tree. But you can use forChild if necessary.

2. Create your form

import { Component } from '@angular/core';
import { FieldConfig } from 'ngx-nomad-form';

@Component({
    selector: 'app-root',
    template: `
      <nf-form [fields]="fields" [formConfig]="formConfig" (callBack)="callBack($event)" (onChange)="change($event)"></nf-form>
    `
})

export class AppComponent {
    
  //Form
  formConfig: FormConfig = {
    name: 'loginForm',
    enctype: 'text/plain',
  };

  //My fields
  fields: FieldConfig[] = [{
    type: 'input',
    label: 'Username',
    inputType: 'text',
    name: 'name',
    readonly: false,
    validations: [{
      name: 'required',
      validator: Validators.required,
      message: 'Name Required'
    }, {
      name: 'pattern',
      validator: Validators.pattern('^[a-zA-Z]+$'),
      message: 'Accept only text'
    }]
  },  {
    type: 'button',
    color: 'danger',
    label: 'Save'
  }];

  ...

  // On Submit
  callBack(value: any){
    console.log(value);
  }

  // Detect change
  change(value: any){
    console.log(value);
  }
}
