Visual editor

The visual editor in mediawiki relies on the parsoid extension, which brings node.js to mediawiki. To install the visual editor extension in a webfaction account, you need to first have node installed and working. You can do this by using the installer in your webfaction panel and associating a path with the app for a domain.

You'll want to set/update your $NODE_PATH and $PATH environment variables to locate the installed node modules, and to find the node and npm binaries

export NODE_PATH="$HOME/webapps/node/lib/node_modules:$NODE_PATH"
echo 'export NODE_PATH="$HOME/webapps/node/lib/node_modules:$NODE_PATH"' >> $HOME/.bashrc
which npm
export PATH="$HOME/webapps/node/bin:$PATH"
echo 'export PATH="/$HOME/webapps/node/bin:$PATH"' >> $HOME/.bashrc

Once node (and npm) is available, you of course need to get the parsoid and visual_editor extensions. A quick npm install in the parsoid directory sets up all the node machinery
