Creating applications

Pega Community logo

Note: The following content, referenced from Pega Community, is included here to help you better achieve the module learning objectives.

Start developing your projects conveniently and intuitively by building your application on an application template. When you create an application on a template, you save time because you reuse key elements of an existing application, such as case types or data types.

You can choose a default application template that Pega Platform provides or reuse one of your existing applications as a template. For example, you can create an application to review mortgage requests, and then supply the application with necessary case types, data types, and other elements. Then, you can build an application to review loan requests by using the application to review mortgage requests as a template. As a result, all assets from the application to review mortgage requests are automatically available in the new application to review loan requests.
Before you begin: For relevant training materials, see a Creating Pega Platform applications module on Pega Academy.
  1. Navigate to the New Application wizard:
    • To build an application in App Studio, in the header of App Studio, click the name of your application, and then click New Application, as shown in the following figure:

    • To build an application in Dev Studio, in the header of Dev Studio, click the name of your application, and then click New Application.
  2. In the header of Dev Studio, click the name of the application, and then click New Application.
  3. Choose a type of application to create:
    • To build an application that joins traditional UI authoring with a unique Theme Cosmos run-time experience, click Build from scratch, and then click Theme Cosmos.

      With a Theme Cosmos authoring experience you can save time by implementing a vast selection of auto-generated functionalities. You can also focus on low-code tools and solutions as Theme Cosmos is primarily designed for App Studio. For more information, see Theme Cosmos.

    • To build an application that uses Cosmos React UI authoring and run-time experience, and is also client-side rendered, click Build from scratch, and then select Cosmos React.

      Cosmos React is an innovative way of designing applications that currently supports a limited range of case management functionalities. For more information, see Cosmos React.

    • To build your application on a custom application template, hover over the application name, click Continue, and then click Build with application template name.

      For more information, see the implementation guide for your application.

    • To search for an application template, click Search all types.
  4. If you build your application on a custom template, and you want to reuse resources from the application, such as case types or data types, import the resources to your new application:
    1. In the Select case types section, select the check box next to each relevant case type.
    2. Click Continue.
    3. In the Select data types section, select the check box next to each relevant data type.
    4. Click Continue.
  5. In the Name your application field, enter a unique name for your application.
  6. Optional: To configure a custom class structure or organization, click Advanced configuration.
    For more information about the settings that you can change, see Configuring advanced settings for new applications.
  7. Click Create application.
  8. Optional: To develop your application more quickly, in the Optionally, add users section, create a team:
    1. In the text field, press the Down arrow key, and then select a user name or an email address.
      If you enter an email address that is new in the system, the system creates a new user.
    2. Control which type of access the user has to your application by selecting a role in the list.
    3. Click Add.

      Caution: If an email account error occurs when you add a user, take note of the user ID and generated password, because the user may not receive these credentials in an email.

  9. Click Go to app.
