• Usage
• Customize at component level
  • Basic fields
  • FieldArray

Getting started

Run npm install @asp-devteam/crud-dialog to install the package in your project.

Be aware that this package requires some peer dependencies to be installed:

• "@angular/common"
• "@angular/cdk"
• "@angular/core"
• "@angular/material"
• "@angular/flex-layout" project

Usage

Next import the CrudDialogModule into your application.

import { CrudDialogModule } from "@asp-devteam/crud-dialog";

@NgModule({
  declarations: [AppComponent],
  imports: [CrudDialogModule],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

If you intend to use the CRUD library in multiple places accross your app, its recommended that you create a separate NgModule that imports and then exports all of your shared modules.

import { CrudDialogModule } from "@asp-devteam/crud-dialog";

@NgModule({
  declarations: [],
  imports: [CrudDialogModule],
  exports: [CrudDialogModule],
})
export class SharedModule {}

Customize at component level

<asp-crud-dialog
  ...
  [submitButton]="'Yes'"
  [cancelButton]="'No'"
></asp-crud-dialog>

Basic fields

import {
  LabelField,
  AutoCompleteField,
  InputField,
  FieldArray,
} from "projects/crud-dialog-library/src/public-api";

fields = new FieldArray();

this.fields.push(
  new AutoCompleteField(
    'user',
    'ID',
    this.users,
    null,
    270,
    {
      validators: [Validators.required],
      customErrors: [
        {
          key:'required',
          message: 'Field is required'
        },
      ]
    },
    true
  ),
  new InputField(
    'first_name',
    'First Name',
    null,
    250,
    null,
    true
  )
);

Next, insert the `` selector in your template.

<asp-crud-dialog [fields]="fields"></asp-crud-dialog>

Can get all the formControl options shown below.

this.fields[0].elems.getFormControl.valueChanges.subscribe((selectedValue) => {
  // change values of inputs based on one selected
  this.fields[1].elems.getFormControl.setValue("test");
  // disable field example
  this.fields[1].elems.enableField();
});

Declare a save function.

public save(form): void {
    this.someService.save(form).subscribe(response => {
      console.log(response);
    });
  }

And add it to your template.

<asp-crud-dialog (save)="save($event)"></asp-crud-dialog>

Change value buttons by default his 'Submit' and 'Cancel'.

<asp-crud-dialog [submitButton]="'Yes'" [cancelButton]="'No'"></asp-crud-dialog>

FieldArray

The FieldArray class not only provides the Array API but also some additional helper methods. These are: -get(name) -> Returns the field which name matches the given name;

Additionaly, to avoid collisions, the field array will throw an error if there are two fields with the same name.
