# go - minimalistic uri shortener

## install dependencies

    npm install

  apparently you can also

    npm install hiredis

  for more awesome.

## run service

    HOSTN=go PORT=80 node .

  if you omit `HOSTN`, then relative shortened uris will be generated.
  if you omit `PORT`, then it's `1337`.

## add uri

    curl -F uri=https://mywaytoolonguri http://go

  this will give you a shortened uri.

## resolve uri

    curl -L http://go/1

## clear database

    redis-cli keys 'go:*' | xargs redis-cli del

  if you have changed `redisPrefix`, then use that instead of `go:`.

## use systemd

  run

    make install

  to install the systemd service and configuration files.
  this will fail if the files are already installed and modified.

  configure `HOSTN` and `PORT` in `/etc/conf.d/go.env` and the user
  and/or group in `/etc/systemd/system/go.service`.

  and finally start the service with

    systemctl start go

  this can fail you haven't configured or useradd the user,
  or if you haven't changed the port and the user isn't allowed to
  listen to fancy ports like `80`.
