Implement a custom UI component using remote module

Level: intermediate

Example

Add a custom UI component to the record page of the custom Requests section. Implement the custom UI component using a remote module created in Angular framework.

1. Create an Angular project to develop a custom UI component using remote module

Create an Angular project to develop a custom UI component using a *.zip archive of an Angular project that contains the template of a remote module.

To create an Angular project using a *.zip archive:

Download and unpack the *.zip archive.
Open the project in Microsoft Visual Studio Code.
Change the <%projectName%> macro of the Angular project name to sdk_remote_module_package in every project file.
Change the <%vendorPrefix%> prefix macro to usr in every project file.
Install the npm modules. To do this, run the npm i command at the command line terminal of Microsoft Visual Studio Code. The installation might take some time.
Update the @creatio-devkit/common library version. To do this, run the npm update @creatio-devkit/common command at the command line terminal of Microsoft Visual Studio Code.

As a result, Microsoft Visual Studio Code will create an Angular project to develop a custom UI component using remote module.

2. Create a custom UI component using remote module

Create an Angular component in the project. To do this, run the ng g c view-elements/input --view-encapsulation=ShadowDom command at the command line terminal of Microsoft Visual Studio Code.

As a result, Microsoft Visual Studio Code will add the InputComponent component files to the src/app/view-elements/input project directory.

Specify that the InputComponent component is a view element.

Open the input.component.ts file.
Flag the component using the CrtViewElement decorator.
Import the required functionality from the libraries to the component.
Save the file.

input.component.ts file
/* Import the required functionality from the libraries. */
import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { CrtViewElement } from '@creatio-devkit/common';

@Component({
  selector: 'usr-input',
  templateUrl: './input.component.html',
  styleUrls: ['./input.component.scss'],
  encapsulation: ViewEncapsulation.ShadowDom
})

/* Add the CrtViewElement decorator to the InputComponent component. */
@CrtViewElement({
  selector: 'usr-input',
  type: 'usr.Input'
})

export class InputComponent implements OnInit {
  constructor() { }

  ngOnInit(): void {
  }
}

Open the app.module.ts file.
Add the InputComponent view element to the CrtModule decorator.
Register the InputComponent view element as a component, i. e., Angular Element, in the ngDoBootstrap() method of the AppModule root module.
Save the file.

app.module.ts file
/* Import the required functionality from the libraries. */
import { DoBootstrap, Injector, NgModule, ProviderToken } from '@angular/core';
import { createCustomElement } from '@angular/elements';
import { BrowserModule } from '@angular/platform-browser';
import { bootstrapCrtModule, CrtModule } from '@creatio-devkit/common';
import { InputComponent } from './view-elements/input/input.component';

@CrtModule({
  /* Specify that InputComponent is a view element. */
  viewElements: [InputComponent]
})
@NgModule({
  declarations: [
    InputComponent
  ],
  imports: [BrowserModule],
  providers: [],
})
export class AppModule implements DoBootstrap {
  constructor(private _injector: Injector) {}

  ngDoBootstrap(): void {
    /* Register InputComponent as an Angular Element. */
    const element = createCustomElement(InputComponent, {
      injector: this._injector,
    });
    customElements.define('usr-input', element);
    
    /* Bootstrap CrtModule definitions. */
    bootstrapCrtModule('create_view_element_from_scratch', AppModule, {
      resolveDependency: (token) => this._injector.get(<ProviderToken<unknown>>token)
    });
  }
}

Build the project. To do this, run the npm run build command at the command line terminal of Microsoft Visual Studio Code.

As a result, Microsoft Visual Studio Code will add the build to the dist directory of the Angular project. The build will have the sdk_remote_module_package name.

3. Add the custom UI component implemented using remote module to the Freedom UI page

Use the Records & business processes template to create a custom Requests app. To do this, follow the instruction in the user documentation: Manage apps.
Set up Creatio for file system development. To do this, follow the instruction in a separate article: External IDEs.
Download the packages to the file system using the Creatio IDE. On the Creatio IDE toolbar, select Download packages to the file system in the File system development mode action group.
Create a Files/src/js directory in the file system’s UsrRequests package directory.
Copy the build from the dist project directory to the Files/src/js directory. The path to the project build is as follows: Files/src/js/sdk_remote_module_package.
Compile the configuration. To do this, follow the instruction in a separate article: Operations in Creatio IDE.
Open the Requests app page workspace and go to the Requests form page page.
Click the button in the action panel of the Freedom UI Designer. After you save the page settings, Creatio opens the source code of the Freedom UI page.

Add the configuration object of the custom component to the viewConfigDiff schema section.

viewConfigDiff schema section
viewConfigDiff: /**SCHEMA_VIEW_CONFIG_DIFF*/[
    ...,
    {
        "operation": "insert",
        "name": "UsrInput",
        "values": {
            "layoutConfig": {
                "column": 1,
                "row": 2,
                "colSpan": 1,
                "rowSpan": 1
            },
            /* The property that defines the element type. */
            "type": "usr.Input",
        },
        "parentName": "SideAreaProfileContainer",
        "propertyName": "items",
        "index": 1
    }
]/**SCHEMA_VIEW_CONFIG_DIFF*/,

Click Save on the client Module Designer’s toolbar.

Outcome of the example

To view the outcome of the example:

Open the Requests app page and click Run app.
Click New on the Requests app toolbar.

As a result, Creatio will display the custom UI component on the request page. The custom UI component is implemented using a remote module created in Angular framework.

You can proceed to implement the business logic. For example, you can implement validation or a custom converter.
