To create your own plugin, see Write a Plugin.
Plugins can be installed in the directory where Haraka was installed (where depends on your OS platform and whether you specified -g) or the Haraka install directory (haraka -i this_path). This example installs my-great-plugin in the Haraka install directory:
cd /etc/haraka
npm install haraka-plugin-my-great-plugin
NPM then installs the plugin and its dependencies in a node_modules directory within the Haraka install directory.
