Example

Add a Custom input component to the custom request page. The component must be an input and include a validator that checks whether the Custom input component added to the custom request page is filled out. The name and value of the input on the page must match the Name field. Add the Custom input component to the library of the Freedom UI Designer. Use the image provided below.

Implement the component using a remote module created in the Angular framework.

Example implementation in Creatio 8.3.4 and later

1. Create an Angular project

To create an Angular project, follow the instructions: Create an Angular project.

For this example:

<%projectName%> macro is set to "sdk_custom_component."
<%vendorPrefix%> macro is set to "usr."

As a result, an Angular project to develop a custom UI component using a remote module will be added.

2. Install npm packages

To install npm packages, follow the instructions: Install npm packages.

As a result, required npm packages are installed.

3. Create a custom Freedom UI component

Ensure the project includes the "AGENTS.md" file. Instructions: Create a custom Freedom UI component (step 1).
Run the ng g c features/runtime/view-elements/input --view-encapsulation=ShadowDom command in the Visual Studio Code terminal to create an Angular component in the project. This adds the InputComponent files to the "src/app/features/runtime/view-elements/input" project directory.

Define the component constants.

Go to the "app/features/runtime/view-elements/input" directory.
Create the "input.constants.ts" file.
Open the "input.constants.ts" file.
Export the following constants that define:
- the view element type
- the view element selector
- the component icon
Save the file.

"input.constants.ts" file
/* The type of the view element.*/
export const INPUT_ELEMENT_TYPE = 'usr.Input';

/* The selector of the view element. */
export const INPUT_ELEMENT_SELECTOR = 'usr-input';

/* Define the component icon as an inline SVG. */
export const INPUT_ELEMENT_ICON =

Define the runtime feature ID.
1. Open the "src/app/features/runtime/runtime-feature.ids.ts" file.
2. Export the constant that defines the runtime feature ID.
3. Save the file.
"runtime-feature.ids.ts" file
```
/* The ID of the runtime feature. */
export const RUNTIME_FEATURE_ID = 'sdk_custom_component-runtime';
```

Specify that the InputComponent is a view element.

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

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

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

/* Register the component as a Freedom UI view element. */
@CrtViewElement({
  selector: INPUT_ELEMENT_SELECTOR,
  type: INPUT_ELEMENT_TYPE,
})

export class InputComponent {

}

Register the InputComponent view element in the runtime feature.

The template already contains the runtime feature activation and bootstrapCrtModule() call. Extend the existing files to register the custom component.

Open the "runtime-feature.module.ts" file.

Add the InputComponent view element to the @CrtModule decorator and Angular module declarations.

"runtime-feature.module.ts" file
/* Import the required functionality from the libraries. */
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { 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: [CommonModule],
})
export class RuntimeFeatureModule {}

Open the "runtime.feature-definition.ts" file.

Define the InputComponent in the discovery.viewElements section.

"runtime.feature-definition.ts" file
/* Import the required functionality from the libraries. */
import type { RemoteFeatureDefinition } from '@creatio-devkit/common';
import { RUNTIME_FEATURE_ID } from './runtime-feature.ids';
import { INPUT_ELEMENT_TYPE } from './view-elements/input/input.constants';

/**
 * Root definition for the runtime feature.
 *
 * Describes the view elements this remote package contributes at runtime
 * and provides the entry points used to load designer metadata and
 * activate the feature.
 */
export const runtimeFeatureDefinition = {
  id: RUNTIME_FEATURE_ID,
  discovery: {
    viewElements: [
      { type: INPUT_ELEMENT_TYPE },
    ],
  },
  loadDesignerDefinitions: (context) =>
    import('./runtime.designer-definitions').then((m) =>
      m.loadRuntimeDesignerDefinitions(context)),
  activate: () =>
    import('./runtime.feature-activation').then((m) => m.activateRuntimeFeature()),
} satisfies RemoteFeatureDefinition;

Open the "runtime.feature-activation.ts" file.

Define the InputComponent view element as an Angular Element. Learn more: Angular elements overview (official vendor documentation).

"runtime.feature-activation.ts" file
/* Import the required functionality from the libraries. */
import { Injector, ProviderToken, Type } from '@angular/core';
import { createCustomElement } from '@angular/elements';
import { bootstrapCrtModule } from '@creatio-devkit/common';

import {
  ensureFeatureModuleRef
} from '../../remote-app-context';

import { RuntimeFeatureModule } from './runtime-feature.module';
import { InputComponent } from './view-elements/input/input.component';
import { INPUT_ELEMENT_SELECTOR } from './view-elements/input/input.constants';
import { REMOTE_ENTRY_NAME } from '../../remote-entry.ids';

function defineCustomElement(
  selector: string,
  component: Type<unknown>,
  injector: Injector): void {
  if (!customElements.get(selector)) {
    customElements.define(selector, createCustomElement(component, { injector }));
  }
}

/* Initialize the runtime feature module and boot the Creatio runtime integration. */
export async function activateRuntimeFeature(): Promise<void> {
  const moduleRef = await ensureFeatureModuleRef(RuntimeFeatureModule);
  const injector = moduleRef.injector;

  defineCustomElement(INPUT_ELEMENT_SELECTOR, InputComponent, injector);

  bootstrapCrtModule(REMOTE_ENTRY_NAME, RuntimeFeatureModule, {
    resolveDependency: (token) =>
      injector.get(token as ProviderToken<unknown>),
  });
}

Save the files.

4. Implement the business logic of the custom Freedom UI component

Implement an input in the component.
1. Open the "input.component.ts" file.
2. Add the value property to the InputComponent component class. The property manages the input value.
3. Flag the value property using the @Input and @CrtInput decorators.
4. Add the label property to the InputComponent component class. The property manages the input name.
5. Flag the label property using the @Input and @CrtInput decorators.
6. Import the required functionality from the libraries into the file.
7. Save the file.
"input.component.ts" file
```
/* Import the required functionality from the libraries. */
import { Component, Input } from '@angular/core';
import { CrtInput, CrtViewElement } from '@creatio-devkit/common';

export class InputComponent {

  /* Add decorators to the value property. */
  @Input()
  @CrtInput()
  /* The input value. */
  public value: string = '';

  /* Add decorators to the label property. */
  @Input()
  @CrtInput()
  /* The input name. */
  public label!: string;

}
```

Track changes of input values.

Open the "input.component.ts" file.
Add the EventEmitter<string>() event to the InputComponent component class. The event tracks input value changes.
Flag the EventEmitter<string>() using the @Output and @CrtOutput decorators.
Import the required functionality from the libraries into the file.
Save the file.

"input.component.ts" file
/* Import the required functionality from the libraries. */
import { Output, EventEmitter } from '@angular/core';
import { CrtOutput } from '@creatio-devkit/common';

export class InputComponent {

  /* Add decorators to the EventEmitter<string>() event. */
  @Output()
  @CrtOutput()
  /* Track input value changes. */
  public valueChange = new EventEmitter<string>();

}

Add the validity flag of the bound attribute to the component.
1. Open the "input.component.ts" file.
2. Add the valueValidationInfo property to the InputComponent component class. The property displays information that the bound attribute is invalid.
3. Flag the valueValidationInfo property using the @Input and @CrtValidationInput decorators.
4. Import the required functionality from the libraries into the file.
5. Save the file.
"input.component.ts" file
```
/* Import the required functionality from the libraries. */
import { Component, Input } from '@angular/core';
import { CrtValidationInfo, CrtValidationInput } from '@creatio-devkit/common';

export class InputComponent {

  @Input()
  @CrtValidationInput()
  /* Display information that the input value is invalid. */
  public valueValidationInfo!: CrtValidationInfo;
}
```

Add the markup of the component to the "input.component.html" file.

"input.component.html" file
<div class="wrapper">
  <label class="label">{{label}}</label>
  <input
    #input
    class="input"
    [class.invalid]="
    valueValidationInfo &&
    !valueValidationInfo.valid && valueValidationInfo.touched
    "
    type="text"
    [value]="value"
    (keyup)="valueChange.emit(input.value)"
  />
</div>

Add the styles of the component to the "input.component.scss" file.

"input.component.scss" file
.wrapper {
  display: flex;
  flex-direction: row;
  gap: 10px;
  padding: 10px;
  align-items: center;
  .input.invalid {
    background-color: #FDD8CF;
  }
}

5. Add the custom Freedom UI component to the Freedom UI Designer

Set up the component layout.

Open the "runtime.designer-definitions.ts" file.
Import the required functionality from the libraries into the file.
Add the metadata of the custom component to the viewElements collection returned by the loadRuntimeDesignerDefinitions() function.
Specify the same public type that you registered in the "runtime.feature-definition.ts" file.
Set up the toolbarConfig property that manages the element layout in the library of the Freedom UI Designer.
Specify the INPUT_ELEMENT_ICON constant in the toolbarConfig.icon property.
Specify the default property values of the component in the defaultPropertyValues property.
Save the file.

"runtime.designer-definitions.ts" file
/* Import the required functionality from the libraries. */
import type {
  RemoteDesignerDefinitionsLoadContext,
  RemoteFeatureDesignerDefinitions,
} from '@creatio-devkit/common';
import { INPUT_ELEMENT_ICON, INPUT_ELEMENT_TYPE } from './view-elements/input/input.constants';

export async function loadRuntimeDesignerDefinitions(
  context: RemoteDesignerDefinitionsLoadContext
): Promise<RemoteFeatureDesignerDefinitions> {
  return {
    viewElements: [
      {
        type: INPUT_ELEMENT_TYPE,
        toolbarConfig: {
          caption: 'Custom input',
          icon: INPUT_ELEMENT_ICON,
        },
        defaultPropertyValues: {
          label: 'Request name',
        },
      },
    ],
  };
}

Run the npm run build command in the Visual Studio Code terminal to build the project.

As a result, the build will be added to the "dist" directory of the Angular project. The build will have the "sdk_custom_component" name.

6. Add the custom Freedom UI component to the Freedom UI page

Create an app based on the "Records & business processes" template. Instructions: Create an app manually (user documentation).

For this example, create a Requests app.
Repeat step 2 of the add the custom Freedom UI component to the Freedom UI page instructions to upload packages to Creatio using the Clio utility.
Open the Requests app in the Application Designer.
Open the Requests form page.
Drag the Custom input component to the canvas.
Click → Source code to open the source code of the Freedom UI page.

Bind an attribute to the page element.

Go to the viewConfigDiff schema section → Input_va390j1 element.
Bind the $UsrName attribute to the value property.

viewConfigDiff schema section
viewConfigDiff: /**SCHEMA_VIEW_CONFIG_DIFF*/[
    {
        "operation": "insert",
        "name": "Input_va390j1",
        "values": {
            "type": "usr.Input",
            "label": "Request name",
            /* The property that defines the input value. Bound to the
            UsrName attribute. */
            "value": "$UsrName",
        }
    }
]/**SCHEMA_VIEW_CONFIG_DIFF*/,

Click Save.

As a result, the Custom input component will be added to the request page.

View the result

Open the Requests section.
Create a request that has an arbitrary name. For example, "Vacation."
Clear the custom input.

As a result, Creatio will display the Custom input component in the request profile of the request page. The name and value of the input on the page match the Name field. If the input is empty, Creatio applies validation. The component is implemented using a remote module created in the Angular framework.

Run the ng g c view-elements/input --view-encapsulation=ShadowDom command in the Visual Studio Code terminal to create an Angular component in the project. This adds the InputComponent files to the "src/app/view-elements/input" project directory.

Specify that the InputComponent is a view element.

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

"input.component.ts" file
/* Import the required functionality from the libraries. */
import { Component, 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
})

/* Register the component as a Freedom UI view element. */
@CrtViewElement({
  selector: 'usr-input',
  type: 'usr.Input'
})

export class InputComponent {

}

Register the InputComponent view element as a component.

Open the "app.module.ts" file.
Add the InputComponent view element to the @CrtModule decorator.
Register the InputComponent view element as an Angular Element in the ngDoBootstrap() method of the AppModule root module. Learn more: Angular elements overview (official vendor documentation).
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('sdk_custom_component', AppModule, {
      resolveDependency: (token) =>
        this._injector.get(<ProviderToken<unknown>>token)
    });
  }
}

4. Implement the business logic of the custom Freedom UI component

Implement an input in the component.
1. Open the "input.component.ts" file.
2. Add the value property to the InputComponent component class. The property manages the input value.
3. Flag the value property using the @Input and @CrtInput decorators.
4. Add the label property to the InputComponent component class. The property manages the input name.
5. Flag the label property using the @Input and @CrtInput decorators.
6. Import the required functionality from the libraries into the file.
7. Save the file.
"input.component.ts" file
```
/* Import the required functionality from the libraries. */
import { Component, Input } from '@angular/core';
import { CrtInput, CrtViewElement } from '@creatio-devkit/common';

export class InputComponent {

  /* Add decorators to the value property. */
  @Input()
  @CrtInput()
  /* The input value. */
  public value: string = '';

  /* Add decorators to the label property. */
  @Input()
  @CrtInput()
  /* The input name. */
  public label!: string;

}
```

Track changes of input values.

Open the "input.component.ts" file.
Add the EventEmitter<string>() event to the InputComponent component class. The event tracks input value changes.
Flag the EventEmitter<string>() using the @Output and @CrtOutput decorators.
Import the required functionality from the libraries into the file.
Save the file.

"input.component.ts" file
/* Import the required functionality from the libraries. */
import { Component, EventEmitter, Input, Output } from '@angular/core';
import { CrtInput, CrtOutput, CrtViewElement } from '@creatio-devkit/common';

export class InputComponent {
  /* Add decorators to the EventEmitter<string>() event. */
  @Output()
  @CrtOutput()
  /* Track input value changes. */
  public valueChange = new EventEmitter<string>();
}

Add the validity flag of the bound attribute to the component.
1. Open the "input.component.ts" file.
2. Add the valueValidationInfo property to the InputComponent component class. The property displays information that the bound attribute is invalid.
3. Flag the valueValidationInfo property using the @Input and @CrtValidationInput decorators.
4. Import the required functionality from the libraries into the file.
5. Save the file.
"input.component.ts" file
```
/* Import the required functionality from the libraries. */
import { Component, Input } from '@angular/core';
import { CrtValidationInfo, CrtValidationInput } from '@creatio-devkit/common';

export class InputComponent {

  @Input()
  @CrtValidationInput()
  /* Display information that the input value is invalid. */
  public valueValidationInfo!: CrtValidationInfo;
}
```

Add the markup of the component to the "input.component.html" file.

"input.component.html" file
<div class="wrapper">
  <label class="label">{{label}}</label>
  <input
    #input
    class="input"
    [class.invalid]="
    valueValidationInfo &&
    !valueValidationInfo.valid && valueValidationInfo.touched
    "
    type="text"
    [value]="value"
    (keyup)="valueChange.emit(input.value)"
  />
</div>

Add the styles of the component to the "input.component.scss" file.

"input.component.scss" file
.wrapper {
  display: flex;
  flex-direction: row;
  gap: 10px;
  padding: 10px;
  align-items: center;
  .input.invalid {
    background-color: #FDD8CF;
  }
}

5. Add the custom Freedom UI component to the Freedom UI Designer

Set up the component layout.
1. Open the "input.component.ts" file.
2. Flag the component using the @CrtInterfaceDesignerItem decorator that has the toolbarConfig property. The property manages the element layout in the library of the Freedom UI Designer.
3. Import the required functionality from the libraries into the file.
4. Upload the following image that is displayed in the library of the Freedom UI Designer to the "input" directory.
5. Run the npm i raw-loader --save-dev command in the Visual Studio Code terminal to transfer the icon in the string format.
6. Set up the toolbarConfig property that manages the element layout in the library of the Freedom UI Designer.
7. Specify the path to the image in the toolbarConfig.icon property.
8. Specify the default property values of the component in the toolbarConfig.defaultPropertyValues property.
9. Save the file.
"input.component.ts" file
```
/* Import the required functionality from the libraries. */
import { CrtInterfaceDesignerItem } from '@creatio-devkit/common';

/* Add the CrtInterfaceDesignerItem decorator to the InputComponent component. */
@CrtInterfaceDesignerItem({
  /* Manage the element layout in the library of the Freedom UI Designer. */
  toolbarConfig: {
    caption: 'Custom input',
    name: 'Custom input',
    /* The path to the component image. */
    icon: require('!!raw-loader?{esModule:false}!./input.svg'),
    defaultPropertyValues: {
      label: 'Request name'
    }
  }
})
```
Run the npm run build command in the Visual Studio Code terminal to build the project.

As a result, the build will be added to the "dist" directory of the Angular project. The build will have the "sdk_custom_component" name.

6. Add the custom Freedom UI component to the Freedom UI page

Create an app based on the "Records & business processes" template. Instructions: Create an app manually (user documentation).

For this example, create a Requests app.
Repeat step 2 of the add the custom Freedom UI component to the Freedom UI page instructions to upload packages to Creatio using the Clio utility.
Open the Requests app in the Application Designer.
Open the Requests form page.
Drag the Custom input component to the canvas.
Click → Source code to open the source code of the Freedom UI page.

Bind an attribute to the page element.

Go to the viewConfigDiff schema section → Input_va390j1 element → values configuration object.
Bind the $UsrName attribute to the value property.

viewConfigDiff schema section
viewConfigDiff: /**SCHEMA_VIEW_CONFIG_DIFF*/[
    {
        "operation": "insert",
        "name": "Input_h2fdvpq",
        "values": {
            "type": "usr.Input",
            "label": "Request name",
            /* The property that defines the input value. Bound to the
            UsrName attribute. */
            "value": "$UsrName",
        }
    }
]/**SCHEMA_VIEW_CONFIG_DIFF*/,

Click Save.

As a result, the Custom input component will be added to the request page.

View the result

Open the Requests section.
Create a request that has an arbitrary name. For example, "Vacation."
Clear the custom input.
