srvdir server the current directory via HTTP.
Example of use:
% ls
index.html
post.html
style.css
% srvdir -http=:8080
This will serve the files index.html, post.html and style.css in the port 8080, so you can point your browser to the url http://localhost:8080/post.html and see the post.html file contents.
It's similar to Python's SimpleHTTPServer, but faster.
To install srvdir from source, you'll need the latest Go and configured (see https://golang.org/doc/install) installed, and run from terminal:
% go get github.com/fsouza/srvdir
Make sure $(go env GOPATH)/bin is in your path.
