livedev is a development proxy server for golang that allows live reloading.
It supports multiple server configuration.

If no match is found the request is routed the default server.

Compatible with: go version go1.0.2+

• Cross-platform
• Unobstructive. No code change required
• Simple json configuration file
• Multiple server support
• Automated build service.
• Dependency change detection

go get -u github.com/qrtz/livedev

livedev is controlled by a json configuration file:

• port: (int, default:"80") proxy port
• GOROOT: (string, optional)
• GOPATH: (string, optional)
• server: ([]Server) A list of Server object with the following options:
  • GOROOT: (string, optional) Server specific GOROOT for compiling with different go version
  • GOPATH: ([]string, optional) Server specific GOPATH.
  • host: (string) server hostname (must be unique)
  • port: (int, optional) server port
    When omitted, the server must accept addr=<hostname:port> argument.
  • workspace: (string, optional) The project root. It will be added to the build process GOPATH
    If omitted, an atempt will be made to guess it from target
  • target: (string, optional) Build target. The file that contains the main function.
    if target is not in the GOPATH, livedev will attempt to add it by guessing the workspace from the filename.
    When target is ommited, the build step is skipped.
  • resources: (optional) A list of resources such as template files. Any change to these files will cause the server to restart.
    • ignore: (string, optional) filename pattern to ignore.
    • paths: ([]string) A list of files or directories to monitor
  • bin: (string, optional) server executable file. When absent, it default to /tmp/livedev[hostname]
  • builder: ([]string, optional) To use a builder other than the go build tool. The first element is the command and the rest its arguments
  • startup: ([]string, optional) server startup argument list
  • default: (bool, optinal) Specifies the default server.
    Defaults to the first server in the list
  • startupTimeout: (int, default=5) Specifies the time (in seconds) limit to wait for the server to complete the startup operation.

        }
    ]
}

$ livedev -c config.json

Assuming you used the above configuration and added example.com to your host file, point your browser to http://example.com
livedev will start your app, compiling it if necessary and forward the request to it on the configured port.

You can have multiple app running with different hostname. Just add another entry in the server list.
