Configuring MediaWiki to use NodeJS and Parsoid

Note: This post references an old version of NodeJS. You can install the latest version of NodeJS and self compile it. to do so, for full details just follow this post.

First you need to download NodesJS, download from

http://nodejs.org/dist/v0.10.20/node-v0.10.20-sunos-x64.tar.gz

Extract to /opt/node and add node to the path

export PATH=/opt/node/bin:$PATH

To get GNU make to work with

export PATH=/usr/gnu/bin:$PATH

Install git and g++ (included in gcc-45

pkg install git gcc-45

Install the extra modules

/wiki/Parsoid/js/api

cp localsettings.js.example localsettings.js

Modify the Parsoid file

parsoidConfig.setInterwiki( 'localhost', 'http://devtech101.com/api.php' );

Start the nodes demon

node api/server.js

Now configure the MediaWiki by modifying the LocalSettings.php

    //Allow read only access

    $wgGroupPermissions['*']['read'] = true;

    ########################################################
    // New visual editor AND Parsoid
    ########################################################

    require_once("$IP/extensions/VisualEditor/VisualEditor.php");

    // OPTIONAL: Enable VisualEditor in other namespaces
    // By default, VE is only enabled in NS_MAIN
    //$wgVisualEditorNamespaces[] = NS_PROJECT;

    // Enable by default for everybody
    $wgDefaultUserOptions['visualeditor-enable'] = 1;

    // Don't allow users to disable it
    $wgHiddenPrefs[] = 'visualeditor-enable';

    // OPTIONAL: Enable VisualEditor's experimental code features
    //$wgVisualEditorEnableExperimentalCode = true;

    $wgVisualEditorParsoidURL = 'http://localhost:8000';
    $wgVisualEditorParsoidPrefix = 'localhost';

Create a startup script, like the below.
cat /etc/init.d/parsoid

#!/bin/bash

# /etc/init.d/parsoid

description="Start Parsoid extension for MediaWiki"

# Some things that run always
export VCAP_APP_PORT="8000"
export NODE_PATH="/wiki/Parsoid/js/node_modules"


# Carry out specific functions when asked to by the system
case "$1" in
  start)
    cd "/wiki/Parsoid/js"
    /opt/node/bin/node /wiki/Parsoid/js/api/server.js >> nohup.out 2>&1 &
    ;;
  restart)
    echo "Stopping Parsoid..."
    echo "pkill -9 node, could do more here..."
    pkill -9 node
    ;;
  'reload'|'force-reload')
    echo "Could fail..."
    cd "/wiki/Parsoid/js"
    /opt/node/bin/node /wiki/Parsoid/js/api/server.js >> nohup.out 2>&1 &
    ;;  
  stop)
    echo "Stopping Parsoid..."
    pkill -9 node
    ;;
  *)
    echo "Usage: $0 {start|stop|restart|reload|force-reload}"
    exit 1
    ;;
esac
