MessagePack Format

This page has moved to docs.servicestack.net/messagepack-format

---

Message Pack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON but it's faster and smaller.

If you ever wished to use JSON for convenience (e.g. storing an image with metadata) but could not for technical reasons (encoding, size, speed...), MessagePack offers a great replacement. Despite the name it ends up being a much better "Binary JSON" than BSON is, as it's much faster, smaller and doesn't require the foreign types like "ObjectId", "UUID" that BSON has.

MsgPack is a great addition to your ServiceStack's web services as it has similar performance to Protocol Buffers (.NET's fastest binary serializer) but is also schema-less like JSON so already works with your Un-Attributed, Clean POCOs - no code-changes required. (as opposed to Protobuf format which requires decorating every serializable property with [DataMember(Order=N)]).

Installing via NuGet

Message Pack is easily installed with the ServiceStack.MsgPack NuGet package:

Install-Package ServiceStack.MsgPack

After the NuGet Package is added to your Project, enable the MsgPack format with:

Plugins.Add(new MsgPackFormat());

The NuGet plugin also includes the MsgPackServiceClient client below so you can easily call it from any C# Client.

Client Usage

Just like the rest of ServiceStack C# Clients, MsgPackServiceClient is interchangeable with the other clients that equally supports all your ServiceStack's services including the New API Design, e.g:

varclient=newMsgPackServiceClient(BaseUri);List<Todo>all=client.Get(newTodos());// Count = 0vartodo=client.Post(newTodo{Content="New TODO",Order=1});// todo.Id = 1all=client.Get(newTodos());// Count = 1todo.Content="Updated TODO";todo=client.Put(todo);// todo.Content = Updated TODOclient.Delete(newTodos(todo.Id));all=client.Get(newTodos());

More examples of using MsgPackServiceClient can be found in the New APIs Integration Test Suite.
