class
A key value store that is transferred from the application on the server side to the application on the client side.
class TransferState { get<T>(key: StateKey<T>, defaultValue: T): T set<T>(key: StateKey<T>, value: T): void remove<T>(key: StateKey<T>): void hasKey<T>(key: StateKey<T>) onSerialize<T>(key: StateKey<T>, callback: () => T): void toJson(): string }
TransferState
will be available as an injectable token. To use it import ServerTransferStateModule
on the server and BrowserTransferStateModule
on the client.
The values in the store are serialized/deserialized using JSON.stringify/JSON.parse. So only boolean, number, string, null and non-class objects will be serialized and deserialized in a non-lossy manner.
