filewatcher

A simple file watcher mainly used with remote configuration

Overview

Allows you to watch a certain configuration file for changes. An event (file:change) is emitted on change that returns the file content and allows you to act on those changes. This is a great tool to use for configuration changes read in one docker container and listened to in another via a shared volume.
