This code currently requires at least version 1.1 of Go, but we encourage the use of the latest stable release. Go is still young and improving rapidly, new releases provide performance improvements and fixes. Information on installation, including pre-built binaries, is available at http://golang.org/doc/install. Stable branches of operating system packagers provided by your OS vendor may not be sufficient.

Run go version to see the version of Go which you have installed.

Run go build inside the directory to build.

Run go test ./... to run the unit regression tests.

A successful build run produces no messages and creates an executable called gnatsd in this directory. You can invoke that binary, with no options and no configuration file, to start a server with acceptable standalone defaults (no authentication, no clustering).

Run go help for more guidance, and visit http://golang.org/ for tutorials, presentations, references and more.

There are several client language bindings for NATS.

• Go
• Java
• Java - Spring
• Node.js
• Ruby
