Introduce

• Reactive-Form was built on Angular Reactive Form
• Reactive-Form helps us to build a form with many types of fields faster

Install

• Step 1: Download package form npm

yarn add @reflaunt/reactive-form

or

npm install @reflaunt/reactive-form

• Step2: Import module (app.module.ts)

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AngularReactiveFormModule, UPLOAD_DIRECTIVE_HEADERS, UPLOAD_DIRECTIVE_API_URL, TINYMCE_CONFIG } from '@reflaunt/reactive-form';

@NgModule({
  declarations: [AppComponent],
  imports: [...ReactiveFormsModule, AngularReactiveFormModule],
  providers: [
    {
      provide: UPLOAD_DIRECTIVE_HEADERS,
      useValue: {
        Authorization: `Bearer ${token}`
      }
    },
    {
      provide: UPLOAD_DIRECTIVE_API_URL,
      useValue: 'http://api.reflaunt.local'
    },
    {
      provide: TINYMCE_CONFIG,
      useValue: {
        apiUpload: '/api/v1/upload',
        paramName: 'files',
        resultTransformer: result => result.data[0].full_path
      }
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

• Step 3: Import style & script (angular.json)

...
 "styles": [
    ...
    "node_modules/primeng/resources/themes/nova-light/theme.css",
    "node_modules/primeng/resources/primeng.min.css",
    "node_modules/primeicons/primeicons.css",
    "node_modules/select2/dist/css/select2.min.css",
    ...
  ],
  "scripts": [
    "node_modules/jquery/dist/jquery.js",
    "node_modules/select2/dist/js/select2.min.js",
    ...
  ],
...

Use

• Declare an array of selections (app.component.ts)

import { InputBase, TextBox } from '@reflaunt/reactive-form';
...
public inputs: any;
ngOnInit() {
    let inputs: InputBase<any>[] = [
      new TextBox({
        key: 'textbox',
        label: 'TextBox',
        classes: ['col-12'],
        group_classes: ['col-12'],
        group: 1
      })
    ];
    this.inputs = inputs;
  }
...

• Show Reactive Form (app.component.html)

...
<reactive-form [(inputs)]="inputs" [onSubmit]="onSubmit" [onChangeReactive]="onChange" [keysChange]="keysChange" [scrollOnErrror]="true" submitText="Save">
</reactive-form>
...

• Use Reset Form Button (app.component.html)

...
<reactive-form ... [isReset]="true">
  ...
</reactive-form>
...

• Use CustomSubmit & CustomButton (app.component.html)

...
<reactive-form ... [customSubmit]="customSubmit" customeSubmitText="ok" [customButton]="customButton" customButtonText="ok1">
  ...
</reactive-form>
...

• Get form value (app.component.ts)

...
onSubmit(form) {
  if (form.valid) {
    console.log('data', form.value);
  }
}

onChange(form) {
  if (form.valid) {
    console.log('data', form.value);
  }
}

customSubmit = form => {
  this.onSubmit(form);
}

customButton = () => {
}
...

Update&fill

• use support.UpdateInputsValue(inputs, optionsData) to update options for Dropdown, Radio, ListCheckBox, Select2

• use supportUpdateFormValue(input, valuesData) to fill data for inputs controll

• Full Example (app.component.ts):

...
keysChange = ['textbox'];

    dropdown: [
      { label: 'Ha Noi', value: 1 },

Validation

Default Validation

https://angular.io/api/forms/Validators

• Use & Example:

...
...
 new TextBox({
        ...
        validators: [
          {
            validator: Validators.required,
            message: 'This field is required'
          },
          {
            validator: Validators.pattern('[a-zA-Z0-9.-_]{1,}@[a-zA-Z.-]{2,}[.]{1}[a-zA-Z]{2,}'),
            message: 'This field must be a email address'
          },
          {
            validator: Validators.minLength(6),
            message: 'Minimmum alowed charactes are 6'
          },
          {
            validator: Validators.maxLength(20),
            message: 'Maximmum alowed charactes are 20'
          }
        ],
        ...
      }),
...

Custom Validation

https://angular.io/guide/form-validation#custom-validators

Reactive-Form provide us some default validator

• isEqualValidator('input-key')
• isDifferentValidator('input-key')
• isExistValidator('apiUrl', 'your-message') - 'apiUrl' must return { exist: true } if item exist

...
import { DefaultValidators } from 'angular-reactive-form';
...
 new TextBox({
        ...
        validators: [
          {
            validator: DefaultValidators.isEqualValidator('input-key'),
            message: 'This field not match with input-key '
          },
          {
            validator: DefaultValidators.isDifferentValidator('input-key'),
            message: 'This field must diffrent with input-key'
          }
        ],
        asyncValidators: [DefaultValidators.isExistValidator(apiUrl, yourMessage)]
        ...
      }),
...

If you want create a custom validator:

• Step 1: Create new file (example.validators.ts)

...
  import { AbstractControl, ValidationErrors, AsyncValidatorFn } from '@angular/forms';

  export function isEqualValidator(matchValue: any) {
    return (control: AbstractControl): ValidationErrors | null => {
      const value = control.value;
      if (value) {
        const compareValue = control.root.get(matchValue).value;
        if (value !== compareValue) {
          return { notEqual: { valid: false, value: control.value } };
        }
      }
      return null;
    };
  }

  export function isExistValidator(url, message): AsyncValidatorFn {
    return (control: AbstractControl): Promise<ValidationErrors | null> | Observable<ValidationErrors | null> => {
      /* Your code */
      return new Promise(async (resolve, reject) => {
        if (value) {
          /* Your code => result */
          if (result.exist === true) {
            resolve({ isExist: { valid: false, value: control.value, message: message } });
          }
          resolve(null);
        }
        resolve(null);
      });
    };
  }
...

• Step 2: Use (app.component.ts)

...
import { isEqualValidator, isExistValidator } from './validators/example';
...
 new TextBox({
        ...
        validators: [
          {
            validator: isEqualValidator('input-key'),
