Overview

DAB interface

Digital App Builder interface consists of the following in the Left navigation panel:

  • Workbench - displays or hides the page details
  • Data - helps you to add a dataset by connecting to an existing data source or create a data source for a microservice using OpenAPI doc.
  • Watson - consists of Image Recognition and Chatbot (Watson Assistant) components for configuring an existing instance or create a new instance.
  • Engagement - You can increase your user engagement with the app by adding Push notifications services
  • Console: displays the console to see the activities and code for each component.
  • Settings: displays the App details, Server info, Plugins, and Repair Project (like Rebuilding dependencies, Rebuilding platforms, Resetting IBM Cloud credentials).

Workbench

Workbench helps you to design the pages. Workbench consists of three work areas:

Workbench

  1. Pages/Controls: This area displays the name of the pages created by default. Use + sign to create a new page. On clicking Controls icon, displays controls that helps in adding functionality to a page in an app. You can drag and drop the controls from the respective Controls pallette to a page’s canvas. Each control has a set of properties and actions.

    Following is the list of controls provided available:

    • Basic: You can drag-and-drop these basic controls (Button, Heading, Image, and Label) to the canvas and configure the properties and actions.

      Pages / Congrols

      • Button - Buttons has a property to label. In the Action tab you can specify the page to navigate to on click of the Button.
      • Heading Text - Helps you to add a heading text for the application such as Page Title.
      • Image - Helps you upload a local image or provide a url of an image.
      • Label - Helps you to add static text to your page body.
    • Databound - helps you to connect with a data set and operate on the entities in the data set. Databound consists of two components: List and Connected Labels

      Databound controls

      • List - Create a new page and drag and drop the List component. Add the List Title, Choose the list type to work on, Add content to work on, and select the dataset to use.
    • Login - Login consists of the Login Form control. Drag and drop the login form to the page.

      The Login Form control helps you to create a login page for your application to connect the user to the Mobile Foundation server. Mobile Foundation server provides a security framework to authenticate users and provide that security context to access the data sets. For more information read here.

      Login Form

      To enable Login Form, perform the following steps:

      1. Make the following changes on Mobile Foundation Server
        • Deploy a security check adapter which would take username and password as input. You can use the sample adapter from here.
        • In the mfpconsole, go to app’s security tab and under Mandatory Application Scope, add the above created security definition as scope element.
      2. Make the following configuration in your Application using the Builder.
        • Add Login Form control to a page in the canvas.
        • In Properties tab, provide the Security check name and the page to navigate On Login Success.
        • Run the app.
    • AI - AI controls allows you to add Watson AI capabilities to your app.

      • Watson Chat - This control provides a complete chat interface that can be powered with Watson Assistant service on IBM Cloud.

        Watson Assistant

        • In the properties section select the configured Watson Assistant service and select the Workspace you want to connect to. To define and train a Chat conversation see Chatbot under Watson.
      • Watson Visual Recognition - This control provides an ability to take a picture and have Watson Visual recognition service identify it for you.

        Watson Visual Recognition

        • In the properties section select the configured Visual Recognition service and the classification model. To define and train using your own images see Image recognition under Watson.
  2. Canvas section - This area consists of the Current Channel selected, Current Page name, Design/Code Toggle, and Canvas.

    • Channel icon - This displays the current channel selected. You can add additional channels by selecting the required channels in the Platforms section under Settings > App > App details.
    • Current Page Name - Displays the canvas page name. When switched between pages, the current page name gets updated to the selected page.
    • Design / Code - This option brings the Code editor view to edit the code and enable to view the design back and debug any errors. In the canvas, switch from Design to Code, to view the code of the specific file in the project editor. Switching the Design to Code will display the following popup screen:

      Design - Code Toggle alert

      WARNING - When you click Create, an editable version of your application is created locally. Any changes made in the editable version will not be reflected in the original app and vice versa. This will display the project explorer with all the project files for the application.

    • Canvas - At the centre of this section is the canvas which displays either the design or the code. You can drag-and-drop the controls and create the app.
  3. Properties/Actions tab - At the right-hand side is the properties and action tab. When a control is placed in the canvas, you can edit and modify the properties of the control and connect a control with a related action to perform.

Data

Creating a Data set for a micro service involves the following steps. After creating the data set, you can connect the data bound controls in your app.

Creating a new data set

  1. From the landing page of the Digital App Builder, open any existing App or create one.
  2. Click Data on the left hand panel.

    Data

  3. Click Add new data set. This displays the Add a data set window.

    Add new data set

  4. Create a data set. You can either create from an existing source (default) or create a data source for a microservice using an OpenAPI doc.
    • Create from existing data source (default) - This will populate the dropdown with all the Data sources (adapters) from the configured Mobile Foundation server instance.
    • Create Data source for a microservice using OpenAPI doc - This option lets you create a Data Source from an Open API specification document (Swagger json/yml) file, and a Data Set from it.

Create a Data set from an existing Data Source

  1. Select the Datasource for which you want to create the Dataset.
  2. This will populate the available entities in the Data Source. Select the entity to be created.
  3. Give a name to the dataset and click the Add button. This will add the dataset and you will be able to see the Attributes and Actions associated with that dataset.

    New dataset with attributes

  4. You can Hide some of the attributes and Actions based on what you want to do with the data set.
  5. You can also edit the Display Labels for the attributes
  6. You can also Test any of the GET Actions by providing the required attributes and clicking on the Run this action which is part of the Action. Remember for this to work you should have specified the Confidential client name and password in the Settings tab.

Create a Data source for a Microservice using a swagger file

  1. Select the json/yml file for which you want to create a datasource for and click Generate.
  2. This will generate an Adapter, which is a configuration artifact on the MF server that you can re-use and deploy it to the Mobile Foundation server instance.
  3. Select the entity for which you want to define the data source for.
  4. Give a name to the dataset and click on Add button.
  5. This will add the Dataset and you will be able to see the Attributes and Actions associated with that dataset.

You can now bind this data set to any of the data bound controls.

Watson

The Digital App Builder provides an ability to configure the app to connect to the various Watson services provisioned on IBM Cloud.

Chatbot

Chatbots are powered by Watson Assistant service on IBM Cloud. Create a Watson Assistant instance on IBM Cloud. For more information, see here.

Once configured you can create a new Workspace. The workspace is a set of conversations that make up a chatbot. After creating a Workspace, start creating the dialogs. Provide a set of questions for a intent and a set of answers for that intent. Watson Assistant uses Natural Language Understand to interpret the intent based on the sample questions you provided. It can then try to interpret the question that a user asks in various styles and map it to the intent.

To enable a chatbot in your app, perform the following steps:

  1. Click Watson and then click Chatbot. This displays the Work with Watson Assistant screen.
