Parsoid/JS/Setup

Before you begin
If you are using Parsoid in conjunction with VisualEditor, note that they are developed in parallel and upgrades to one often require a corresponding upgrade to the other. If in doubt, please check the Extension:VisualEditor page and follow its setup instructions first.

Of course, Parsoid can be used stand-alone (to convert wikitext to HTML DOM and vice-versa) and if you don't need VisualEditor, you can ignore the above.

Ubuntu / Debian on amd64
These packages work on amd64 and with current distros: Ubuntu 14+ and Debian testing, unstable or wheezy (stable) with backports enabled. See the manual installation instructions below if your distribution is older & doesn't have nodejs >= 0.8 available.

Import the repository gpg key: gpg --keyserver keys.gnupg.net --recv-keys 6BF6E273 gpg -a --export 6BF6E273 | sudo apt-key add - Add the parsoid repository to your  file deb [arch=amd64] http://parsoid.wmflabs.org:8080/deb wmf-production main

To install, sudo apt-get update && sudo apt-get install parsoid

Notes: The configuration for the deb lives in  and   (the equivalent of  ). The default port used is 8142. The log file is, and is automatically rotated.
 * We currently only provide packages for amd64. You'll get 404s when using another architecture, such as i386. The repository location will eventually change to an official WMF repository once that is set up.
 * If you are on an older distribution and nodejs >= 0.8 is not available, see the Nodejs installation section below.

Vagrant
If you are using the MediaWiki-Vagrant virtual machine, the  role sets up a working Parsoid.

Windows Setup
Parsoid has a nested dependency on a Node.js module called Contextify (parsoid → html5 → jsdom → contextify). Furthermore, Contextify itself has dependencies on external tools: Python and the "Visual C++" compiler.

Install prerequisite software
Before you can install Parsoid on Windows you will need to install the following software packages:


 * 1) Install Git for Windows (pick Run Git from the Windows command prompt) http://git-scm.com/download/win
 * 2) Install Visual C++ 2010 Express (you can uncheck the SQL part) http://www.visualstudio.com/downloads/download-visual-studio-vs Visual C++ with service pack is a rather large download, with several hundred MB.
 * 3) Install Python27 (not Python33) http://www.python.org/ You will need to add the Python directory to the System Variable PATH.  If you have a default installation of Python27, then go to Control Panel→System→Advanced system settings→Environment Variables...→PATH→Edit... and add ;c:\Python27 to the end of the current Variable value:.
 * 4) Install Node.js x86 edition http://nodejs.org/download/ As of August 2014 is still important for the compilation of Contextify to install the x86 edition of Node.js, even on x64 systems!

Install Contextify
After the installation of the software from above, you can install Contextify. For this, open a command prompt, enter the path of the Node.js installation (e.g. C:\Program Files (x86)\nodejs) and run: npm install contextify If you are using a x64 version of Node.js, you will get a error-message in red saying '"... MSB8007: The Platform for project 'validation.vcxproj' is invalid. Platform='x64'. ..."'. You need to install the x86 version of Node.js in that case.

If python is missing, you'll get an error-message as well.

You might also get the following error-message (or a similar error-message): Error: ENOENT, stat 'C:\Users\User Name\AppData\Roaming\npm' In that case you will need to browse to the 'Roaming' folder, and create an empty folder named 'npm' there. The path to the folder will depend on your Windows installation, and on your username!

Install Parsoid
If installing contextify succeeded you can do the following - these steps are the same as the installation of Parsoid on Linux: git clone https://gerrit.wikimedia.org/r/p/mediawiki/services/parsoid cd parsoid ..\npm install

When the installation is complete, configure parsoid and run: node api\server.js

To run parsoid in the backgroud, create a cmd file in the parsoid directory called parsoid.bat. Setup a scheduled task to run the task on startup. Alternatively several "run batch file as a service" commands exist on the internet. @echo off "%ProgramFiles(x86)%\nodejs\node.exe" api\server.js When using the cmd file as scheduled task it might be required to use the full path to the server.js file (e.g. C:\www\parsoid\api\server.js) instead of api\server.js.

Get the code
If you want to do an anonymous checkout:

Or if you plan to hack Parsoid, then please follow the Gerrit 'getting started' docs and use an authenticated checkout url instead, such as:

Nodejs
Install nodejs 0.8 or 0.10. When you are using Ubuntu and depending on OS version you will not end up with the most recent version of nodejs please read this first before you proceed:

On Ubuntu Server 12.04 LTS and Ubuntu Server 14.04 LTS instead do (to get v0.10.x) :

For other systems, see:
 * http://nodejs.org/download/
 * https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
 * (debian squeeze, wheezy) https://gist.github.com/x-Code-x/2562576

JS dependencies
Install the JS dependencies. Run this command in the Parsoid directory (/usr/lib/parsoid):

To find the Pasoid directory:

On Ubuntu Server 14.04 LTS run since running of node-gyp requires root access

Configuration
If you would like to point the Parsoid web service to your own wiki, go to the  directory and create a   file based on. Use  to point to the MediaWiki instance(s) you want to use like this:

Currently Parsoid supports public wikis, and private wikis using cookie forwarding. (See bug 67313 for some more hints on getting this working.)

You can then access pages of your wiki in Parsoid with the relative URL '/someuniqueid/page-title/'

Run the server
You should be able to start the Parsoid web service from the parsoid directory using:

This will start the Parsoid HTTP service on port 8000. To test it, point your browser to http://localhost:8000/. If you configured the 'localhost' prefix correctly, you should be able to parse pages via http://localhost:8000/localhost/.

Two environment variables are available to control binding to a specific interface and/or port:

export INTERFACE=127.0.0.1 export PORT=8142 nodejs api/server.js

Starting the Parsoid service automatically
There are many ways to start services automatically, consult your server's operating system documentation.

On Ubuntu and other operating systems using Upstart, one approach is where /etc/init/parsoid.conf contains configuration similar to MediaWiki-Vagrant's :

On recent versions of Fedora and other operating systems using systemd, use a parsoid.service unit file similar to the following template (modify the file paths as appropriate): The optional  directive above can specify the path to a file similar to the following template:

See bug 53723 for packaging plans that should make the general installation easier.
