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. The -proxy flag can be useful when used as a development server.
❯ spark -h
Usage of spark:
-address="0.0.0.0": Listening address

-status=200: Returned HTTP status code
-path="/": URL path
-deny="": Sensitive directory or file patterns to be denied when serving directory (comma separated)

$ spark message.html
$ spark "<h1>Out of order</h1><p>Working on it...</p>"
$ spark static_site/
$ spark -port 80 -sslPort 443 "<h1>Ooops!</h1>"
$ spark -deny ".git*,LICENSE" ~/go/rif/spark
$ spark -proxy "/api=>http://localhost:9090/api" .
To quickly generate a ssl certificate run:
go run $GOROOT/src/crypto/tls/generate_cert.go --host="localhost"
