Chrome "REST Console" plugin tool

REST Console @ Chrome Store

REST Console is an HTTP Request Visualizer and Constructor tool, helps developers build, debug and test RESTful APIs.

JSV Format

Included as data serialization option with ServiceStack,
"JSV" is a optimized for speed and simplicity.

JSV Format:
"JSV Text Format (JSON + CSV)
Type Serializer uses a hybrid CSV-style escaping + JavaScript-like text-based format that is optimized for both size and speed"

C#: new MyClass { A=1, B=2, C=3, D=4 }
JSV: {A:1,B:2,C:3,D:4}

JSV is white-space significant, which means normal string values can be serialized without quotes, e.g:

C#: new MyClass { Foo="Bar", Greet="Hello World!"} is serialized as
JSV: {Foo:Bar,Greet:Hello World!}

CSV escaping
Any string with any of the following characters: []{}," is escaped using CSV-style escaping where the value is wrapped in double quotes, e.g:

C#: new MyClass { Name = "Me, Junior" }
JSV: {Name:"Me, Junior"}

C#: new MyClass { Size = "2\" x 1\"" }
JSV: {Size:"2"" x 1"""}

So why bother? The answer is: performance.
When both ends of communication (i.e. client & server)
support more optimal format, it makes sense to use it.
