Early Adopter's guide to Umbraco v14 [Trees] - Repositories

Once we have our data out in to a datasource, we can add it to our repository pattern and we are soooo nearly there !

Code for these posts is avalible in our TimeDashboard Repository FrontEnd (typescript) & Backend (c#)

Tree Repository.

Again to save on so much code, we are extending an umbraco UmbTreeRepositoryBase class.

This class takes our item/entity models. which is why we set them up first.

export class TimeTreeRepository extends 
    UmbTreeRepositoryBase<TimeTreeItemModel, TimeTreeRootModel>
    implements UmbApi

in our constructore we pass our datasource, and a refernce to the store context.

    constructor(host: UmbControllerHost) {
        super(host, TimeTreeServerDataSource, TIME_TREE_STORE_CONTEXT);
    }

The all we have to do is prodivde a requestTreeRoot method to return our tree route model

    async requestTreeRoot() {

        const data: TimeTreeRootModel = {
            unique: null,
            entityType: TIME_TREE_ROOT_ITEM_TYPE,
            name: 'time',
            hasChildren: true,
            isFolder: true,
        };

        return { data };

    }
