Update your SAP Web IDE MTA applications to use the HTML5 Application Repository

SAP recently released a new SAP Cloud Platform Portal and HTML5 Repository Service that  provide a rich set of new capabilities for development of Enterprise Full stack Applications with SAP Fiori experience for SAP Cloud Application on Cloud Foundry.

The new services are fully integrated into Multi-Target Application (MTA) and provide multiple new capabilities:

  • Integrated FLP Design Time Content Development with a Visual Editor
  • High speed content serving from HTML5 repository in runtime
  • New Portal Service providing End User Settings and Personalization for Launchpad and HTML5/Fiori Applications
  • Development of multiple HTML5/Fiori Applications including routes within one MTA
  • and more

New MTA Projects created in SAP Web IDE are already making use of these new capabilities.

In this guide we want to explain how to update an existing Multi-Target Application (MTA) to use the new HTML5 application repository and Portal Service on the SAP Cloud Platform Cloud Foundry environment.

We will use SAP Web IDE Full-Stack to create a new MTA Project and then we will take the required parts from the new project and add them to the old project.

Create an MTA project and add an HTML5 module

  1. In SAP Web IDE Full-Stack, right-click on the workspace and create a new Project from Template.

 

2. Select Multi-Target Application and click Next.

3. Enter a name for your project

4. Select the Use HTML5 Application Repository This is mandatory because the

SAP Fiori  launchpad solution stores static resources in the HTML5 repository.

  1. Click Finish.

A project was created in your SAP Web IDE workspace.

  1. Add an SAPUI5 module.
  •      Right-click on your newly created project and select HTML5 Module.

 

 

  • Select SAPUI5 Application and click

  • Provide the module name and namespace, click Next and then Finish. The SAPUI5 module is now added to your project.

Manual changes required to make use of HTML5 application repository and FLP Service in your project

As you now have a new project that uses the HTML5 application repository, you can compare it with the existing project to understand the differences and in order to make the needed adjustments in your project.

Add the new appRouter and ui_Deployer modules to your project

The appRouter and ui_Deployer modules are hidden in the project tree. To make them visible, click on the eye icon above your workspace.

The appRouter module is responsible for the interaction with applications, services, and resources during runtime.

The ui_Deployer module is responsible for uploading the HTMl5 module content to the HTML5 Application Repository.

 

  1. Copy the appRouter module and paste it in your project. In the new project, right-click on the appRouter folder, select Edit and then Copy.

 

2. Paste the copied folder under your original project’s root folder.

3. Copy the ui_Deployer module and paste it in your project the same way you copied the AppRouter.

4. Open the modules file located in the .che folder of your original project.

5. Add the names of the newly added modules.

 

  1. The project contains an yaml file. It is a descriptor of the project and its resources. Let’s update it to contain the changes we’ve made in the previous steps.
  • Open the yaml file in the new project, copy the deploy_mode parameter and add it to the mta.yaml of your original project.
  1. Add the appRouter and ui_Deployer modules to the yaml under the modules section.
  • Open the mta.yaml file in the new project, copy the appRouter and ui_Deployer sections, and add them to the yaml of the original project.

 

  • Add the required dependencies for the appRouter (UAA, Portal Service, Backend Destination, HTML5 Repo runtime, etc).
  1. Add all the HTML5 modules in your project under the ui_deployer build-parameters section to connect the UI modules to the ui_deployer.
  2. Open the xs-app.json file in each of your HTML modules and add the HTML5 Application Repository routing configuration

 

The HTML5 Application Repository consists of two service plans, the app-host which is responsible for the deployment of HTML5 applications to the repository, and the app-runtime which consumes HTML5 applications from the HTML5 application repository.

 

11. Copy the app-runtime and app-host section under the resources section and paste it

in the yaml file of the original application

12. Now you can build your application. From the context menu of your project select Build

  1. Expand the folder with your project name under the mta_archives folder to find the MTAR file (Multi target application archive) that was created in the build process
  2. From the context menu of the mtar file select Deploy and Deploy to SAP Cloud Platform

 

 

15. The deployment process deploys the app-router application. In order to launch

your application, you should construct the app URL in the following format:

           https://<app-router URL>/<application name>/index.html

 

The app router URL can be copied from the console after deployment or from the deployed      application in the cockpit

The application name is the app.id in manifest.json without the dots

 

16. If the deployment fails, go to the marketplace in your cockpit, click on the

            HTML5 Application Repository service and verify that you have 2 service plans

(app-runtime and app-host)

If you don’t have the app-host service plan you should ask your administrator to assign some quota of app-host service plan to your global account (in MB) and entitle your sub account in the cockpit entitlements to use part of this quota.

  • Hi Elizabeth,

    I am getting using a custom UI5 application in between and add portal module and I when I am trying to build the same I am getting an error saying “Invalid mta.yaml. Make sure that the required module or resource dt_<<ProjectName>>_appRouter is defined.”

    In this scenario which folder should copy & paste as per your above.

    Looking forward to hear from you.

    Regards,

  • Hi Elizabeth Gutt,

    two more questions:

    • How do I specify environment variables for the router (like XS_APP_LOG_LEVEL or REQUEST_TRACE) in such an mta.yml utilizing the HTML5 Repo?
    • Can I specify in the mta.yml utilizing the HTML5 Repo to reuse an existing destination service rather than creating a new one (we have a quota of 1 for destination service…)?

    Regards,

    Wolfgang
