  • This is where we store active WebSockets.

    Declaration

    Swift

    var websocketStorage: WebSocketStorage { get set }
    Show on GitHub

  • This is the datatype that gets stored in UserCacheStorage. Vapor’s Services API uses this. Making this a class instead of a struct. This prevents internal modifications (e.g. adding/removing a value from the dicts) from causing the entire app.storage getting copied, in the case where app.storage is a value type composed of other value types. The custom setter for app.storage is not thread-safe. So, this is a workaround for app.storage having a non-thread-safe setter.
