Module types

Base modules

Creatio implements the following base modules:

  • ext-base. Implements the ExtJs framework functionality.
  • terrasoft in the Terrasoft namespace. Implements access to system operations, core variables, etc.
  • sandbox. Implements a mechanism that exchanges messages among modules.
Example that accesses the ext-base, terrasoft, and sandbox modules
/* Define a module and retrieve links to dependency modules. */
define("ExampleModule", ["ext-base", "terrasoft", "sandbox"],
/* "Ext" is the link to the object that provides access to the ExtJS framework.
"Terrasoft" is the link to the object that provides access to system variables, core variables, etc.
"sandbox" is the link to the object required to exchange messages among modules. */
function (Ext, Terrasoft, sandbox) {

Most client modules use base modules. You do not have to specify base modules in dependencies. After you create a module object, the Ext, Terrasoft, and sandbox objects become available as the this.Ext, this.Terrasoft, and this.sandrenderbox object properties.

Client modules

Client module types

  • non-visual module
  • visual module
  • replacing module

View the client module hierarchy below.

Non-visual module

The purpose of a non-visual module is to implement Creatio functionality that is usually not related to binding data and displaying data in the UI. For example, business rule modules (the BusinessRuleModule schema in the NUI package) and utility modules that implement service functions are non-visual modules.

To implement a non-visual module, follow the instructions in a separate article: Client module.

Visual module

Visual modules are modules that implement view models (ViewModel) in Creatio based on the MVVM pattern. Learn more about the MVVM pattern in Wikipedia.

The purpose of a visual module is to encapsulate data visualized in the UI controls and the methods of working with data. For example, section, detail, and page modules are visual modules.

To implement a visual module, follow the instructions in a separate article: Client module.

Replacing module

The purpose of a replacing module is to extend the base module’s functionality. Modules that replace base functionality modules do not support inheritance in its traditional sense. You cannot use the resources of the replaced module in the replacing module. Instead, recreate resources in the replacing schema.

To implement a replacing module, follow the instructions in a separate article: Client module.

Client module methods

Creatio lets you implement the following methods in client modules:

  • init(). Implements the logic executed as part of loading the module. The client core calls this method first automatically when loading the module. The init() method usually subscribes to events of other modules and initializes the module values.
  • render(renderTo). Implements the module visualization logic. The client core calls this method automatically when loading the module. To ensure data is displayed correctly, the mechanism that binds the view (View) and view model (ViewModel) must be triggered before data visualization. As such, this mechanism is usually initiated in the render() method. by calling the bind() method in the view object. If the module is loaded into a container, Creatio passes the link to that container to the render() method as an argument. The render() method is required for visual modules.

Utility modules

Although module is an isolated software unit, it can use the functionality of other modules. To do this, import the needed module as a dependency. Use a factory function argument to access an instance of a dependency module.

During development, you can group auxiliary and service general-purpose methods into separate utility modules. Import the utility module into a module to use the functionality.

Work with resources

Resources are additional schema properties. Add resources to the client module schema in the properties area of the Module Designer (the button).

Creatio lets you use the following resources:

  • localizable strings (the Localizable strings property)
  • images (the Images property)

The [ClientModuleName]Resources module contains the resources that the Creatio core generates for each client module automatically.

To access the resource module from the client module, import the resource module into the client module as a dependency.
