Sharing Assets Between Portals

If you are devloping an application that contains multiple Portals, the Portals library supports the ability to share asset files between them. This is helpful to reduce the size of your overall app if those Portals use assets that are the same such as large media files or font files.

Register Shared Assets​

Create a directory in the src/main/assets directory to hold shared assets for your Portals. In this example we will name this directory "shared". Therefore, the full path of the shared asset directory where we will place the shared resources is src/main/assets/shared.

Next, when creating the Portal register an AssetMap for the shared asset directory. The first property is a name for your shared assets registration, followed by a virtual path the web content will use. The last property is the name of the directory we created for the shared assets, "shared".

PortalManager.newPortal("myportal")
    .addAssetMap(AssetMap("myshared","/shared/assets","shared"))
    .create()

When this Portal loads, the shared asset information will be passed to the web content as part of the Portal's InitialContext object.

Using Registered Assets​

Refer to the page in the Web docs to learn how to use your registered shared assets in your web content.
