TransferState
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
}Description
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 deserialzied in a non-lossy manner.
