Adding simple Go server

[tehbilly]

Adding a very simple go server to the list. Primarily because when I went to test this out I could just run it via node without changing the listen port in server/index.js. Plus, I'm not really a node guy!

From the server directory you can run the following to have exactly what you have with the node version:

$ go run index.go

However, I'd recommend just building the binary and running that.

$go build && ./server -h
Usage of ./server:
  -listen="0.0.0.0:80": Where the server listens for connections. [interface]:port
  -scripts="./modules/shell_files": Location of shell scripts used to gather stats.
  -static="../": Location of static files.

Can use command line args to specify location of scripts/modules, listen address, and path for static files.

Thanks. I know nothing about Go but have added your instructions to the README.

I'll be happy to elaborate a little more if you'd like. When I get back to my computer, so I can do it properly.

Seems like a good fit for this project as go can build a statically linked binary, so zero dependencies needed on the box it's running on.

Alright, so, as promised I'm elaborating! Go is a language that compiles down to statically linked executables, and the stdlib includes some very useful packages for creating servers. In this case, it seems like a perfect fit as you're trying to create a simple and low-overhead application that does one thing and does it well.

With zero optimizations, compiling a 32-bit version of the index.go file I submitted creates a 4.8MB executable that consumes about 3.3MiB of RAM on my home server. A couple of extra flags brings that down to a 3.3MB file that consumes 3.2MiB of RAM. Pretty much as easy peasy as you can get for a completely standalone server that can serve up your entire application.

Throw in a few init scripts to help manage it as a service and you've got a completely self-contained service that will run on literally any linux machine with nothing else to install.

Great feature ! Thank @tehbilly

Hi.

I'm getting this error from last version and your sample command line:

./server -listen="0.0.0.0:80" -scripts="./modules/shell_files" -static="../"
flag provided but not defined: -scripts
Usage of ./server:
  -listen string
        Where the server listens for connections. [interface]:port (default "0.0.0.0:80")
  -static string
        Location of static files. (default "../")

It looks like that's no longer needed, try running it without that flag and it should work.
