ShareLaTeX

ShareLaTeX is a web based collaborative LaTeX editor. There are two versions of it, the online version that anyone can sign up to at www.sharelatex.com, and this open source version which allows anyone to run a local installation of ShareLaTeX.

This repository pulls together all of the different services in ShareLaTeX's service orientied architecture (SOA).

Installation

First, check out a local copy of this repository:

$ git clone git@github.com:sharelatex/sharelatex.git
$ cd sharelatex

Next install all the Node modules and ShareLaTeX services:

$ npm install
$ grunt install

When that has finished, run ShareLaTeX with

$ grunt run

ShareLaTeX should now be running at http://localhost:3000.

Dependencies

You need:

• Node.js 0.10 or greater
• Grunt command line tools (Run npm install -g grunt-cli to install them)
• A local instance of Redis and Mongodb running on their standard ports.

Other repositories

ShareLaTeX consists of many separate services, each with their own Node.js process and source code repository. These are all downloaded when you run npm install and they are run when you run grunt run.

The different services are:

web-sharelatex

The front facing web server that serves all the HTML pages, CSS and javascript to the client. Also contains a lot of logic around creating and editing projects, and account management.

document-updater-sharelatex

Process updates that come in from the editor when users modify documents. Ensures that the updates are applied in the right order, and that only one operation is modifying the document at a time. Also caches the documents in redis for very fast but persistent modifications.
