To do this it takes in a `TUniversalView` type parameter (the external data interface), and a list of one or more "Model Descriptors" which can identify whether the DataStoreRuntime matches that model (similar to `refreshRoot` in the base branch), as well as how to initialize a new DataObject with that model. Each Model Descriptor yields a model that fits into `TUniversalView`. The simplest way to specify `TUniversalView` is to just union all the individual model types. (The example below makes a different choice) ### Updating DataObject and TreeDataObject This PR also illustrates updating DataObject and TreeDataObject to use MigrationDataObject. We could deprecate those if we get MigrationDataObject to a place we like, and existing subclasses of DataObject could switch to MigrationDataObject directly. Then they'd be ready if/when a migration is needed. Maybe we simply put the new capabilities on PureDataObject instead of introducing a new class. ### Example See `demo.ts`. The Model Descriptor for the classic "root SharedDirectory" DataObject checks for a channel with ID "root" that's a SharedDirectory, whereas the Descriptor for the "root SharedTree" DataObject checks for "root-tree" channel that's a SharedTree. The `TUniversalView` here is this abstraction, taken from the prototype component code: ```typescript readonly getArbitraryKey: (key: string) => string | boolean | undefined; readonly setArbitraryKey: (key: string, value: string | boolean) => void; readonly deleteArbitraryKey: (key: string) => void; readonly getRoot: () => { isDirectory: true, root: ISharedDirectory } | { isDirectory: false, root: ITree, }; ``` ## Reviewer Guidance There are plenty of todos and some gaps. Some listed below. Any and all feedback is welcome, but focusing on higher-level is more helpful in the short term. ### Gaps / open questions - We need something like an "evacuateModel" function on ModelDescriptor to clean up unreferenced channels after migration - API / experience around how you'd roll out a new ModelDescriptor and stage the migration is not fleshed out. - Reminder this is targeting a WIP feature branch, so the rest of the migration flow is PoC quality as well Thanks for taking a look! --- .../api-report/aqueduct.legacy.beta.api.md | 84 ++++++- packages/framework/aqueduct/package.json | 9 +- .../delayLoadChannelFactory.ts | 4 +- .../dataObjectFactory.ts | 55 +++-- .../migrationDataObjectFactory.ts | 198 ++++++++++------ .../treeDataObjectFactory.ts | 53 +++-- .../aqueduct/src/data-objects/dataObject.ts | 112 +++++---- .../aqueduct/src/data-objects/index.ts | 4 +- .../src/data-objects/migrationDataObject.ts | 183 +++++++++------ .../src/data-objects/treeDataObject.ts | 93 +++++--- packages/framework/aqueduct/src/demo.ts | 222 ++++++++++++++++++ packages/framework/aqueduct/src/index.ts | 5 + .../validateAqueductPrevious.generated.ts | 2 + 13 files changed, 752 insertions(+), 272 deletions(-) create mode 100644 packages/framework/aqueduct/src/demo.ts diff --git a/packages/framework/aqueduct/api-report/aqueduct.legacy.beta.api.md b/packages/framework/aqueduct/api-report/aqueduct.legacy.beta.api.md index d9d9860aa992..062020869bd5 100644 --- a/packages/framework/aqueduct/api-report/aqueduct.legacy.beta.api.md +++ b/packages/framework/aqueduct/api-report/aqueduct.legacy.beta.api.md @@ -71,14 +71,16 @@ export interface CreateDataObjectProps extends PureDataObject { - protected getUninitializedErrorString(item: string): string;
