spark

Emergency web server

For those occasions when your webserver is down and you want to display a quick maintainance note. Or just want to quickly demo a static site. Or whatever :)

It can take a directory, a file or directly the body string.

❯ spark -h

$ spark message.html
$ spark "<h1>Out of order</h1><p>Working on it...</p>"

go get github.com/rif/spark

crossbuild

Just run ./crossbuild.sh (needs go 1.5 or later). It also compresses the binaries with upx, comment those lines if you don't need compression.
