# Create an Entando Platform Capability

An Entando Platform Capability, or EPC, is a packaged capability in the form of a bundle that adds functionality to the platform with additional UX controls. An EPC simplifies the addition of menu options, an API management page, or WCMS integration like Strapi, all from the App Builder. This tutorial demonstrates how to build a simple EPC from a React micro frontend bundle.

# Prerequisites

  • A working instance of Entando
  • An existing React MFE

# Create a Simple EPC

Working with the React MFE Tutorial, the following steps convert the React bundle into an EPC by modifying the bundle descriptor and customizing the public path to serve static assets.

# Configure the Bundle Descriptor

Edit the bundle descriptor entando.json in the root bundle directory.

  1. Change the type to app-builder:
  "type": "app-builder" 
  1. Remove the titles attribute

  2. Add the fields in the code snippet below:

"slot": "content",
"paths": ["/YOUR-MFE-NAME"],
"nav": [
    {
        "label": {
          "en": "YOUR EPC LABEL IN ENGLISH",
          "it": "YOUR EPC LABEL IN ITALIAN"
        },
        "target": "internal", 
        "url": "/YOUR-MFE-NAME"
    }
],    
  • type: Use app-builder for an EPC
  • slot: Placement of the EPC on a page
  • paths: The URL path to the EPC in the App Builder. An external URL can be entered
  • nav: The visible label for the navigation item in the App Builder Menu

For more details on attributes, see the Bundle Details page.

Note: To continue with the same name as the React bundle, update the version number in the bundle descriptor entando.json. Otherwise, change the bundle name to avoid name conflicts in your Local Hub.

# Optional: Configure the Custom Element Paths

If you have static assets such as images or PDFs in your MFE, modify the public-path.js file in the microfrontends/YOUR-MFE-NAME/src/custom-elements directory.

  1. Retrieve the bundle ID using your information for the fields in all-caps:

    ent ecr get-bundle-id https://registry.hub.docker.com/YOUR-DOCKER-ORGANIZATION/YOUR-BUNDLE-NAME
    

    YOUR-BUNDLE-ID will be an 8-digit string of numbers and letters.

  2. Determine the bundle and widget codes. The CODE is simply the name followed by a dash and YOUR-BUNDLE-ID.

    YOUR-BUNDLE-CODE: YOUR-BUNDLE-NAME-YOUR-BUNDLE-ID
    YOUR-WIDGET-CODE: YOUR-WIDGET-NAME-YOUR-BUNDLE-ID

    e.g. With a bundle named bundleOne, a widget named mfeTwo, and bundle ID of 4986eb9c: YOUR-BUNDLE-CODE: bundleOne-4986eb9c
    YOUR-WIDGET-CODE: mfeTwo-4986eb9c

  3. Using your CODEs, replace the contents of public-path.js with the following:

if (process.env.NODE_ENV === 'production') {
    let publicpath = '/entando-de-app/cmsresources/bundles/YOUR-BUNDLE-CODE/widgets/YOUR-WIDGET-CODE/'
    // eslint-disable-next-line no-undef
    __webpack_public_path__ = publicpath || './';
}

e.g. for the example from Step 2:
publicpath = '/entando-de-app/cmsresources/bundles/bundleOne-4986eb9c/widgets/mfeTwo-4986eb9c/'

# Build and Install the EPC

  1. From the bundle root directory, build and deploy the bundle:
ent bundle pack
ent bundle publish
ent bundle deploy
  1. Log in to your App Builder.

    • Go to Hub from the left menu
    • Click on the Deployed button for your EPC and choose Install
  2. To see the new EPC:

    • Go to EPC from the left menu and choose Uncategorized
    • Click on your EPC label
      You should see the spinning React logo inside the App Builder.

Congratulations!

You now have an EPC running on Entando!
