Key Features
Overleaf is an open-source online real-time collaborative LaTeX editor. We run a hosted version at www.overleaf.com, but you can also run your own local version, and contribute to the development of Overleaf.
Keeping up to date
Sign up to the mailing list to get updates on Overleaf Releases and development
Installation
We have detailed installation instructions in our wiki:
Upgrading
If you are upgrading from a previous version of Overleaf, please see the Release Notes section on the Wiki for all of the versions between your current version and the version you are upgrading to.
Other repositories
This repository does not contain any code. It acts a wrapper and toolkit for managing the many different Overleaf services. These each run as their own Node.js process and have their own GitHub repository.
| Service | Description |
|---|---|
| web | 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 | Processes 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. |
| CLSI | The Common LaTeX Service Interface (CLSI) which provides an API for compiling LaTeX documents. |
| docstore | An API for performing CRUD (Create, Read, Update and Delete) operations on text files stored in Overleaf. |
| real-time | The websocket process clients connect to. |
| filestore | An API for performing CRUD (Create, Read, Update and Delete) operations on binary files (like images) stored in Overleaf. |
| track-changes | An API for compressing and storing the updates applied to a document, and then rendering a diff of the changes between any two time points. |
| chat | The backend API for storing and fetching chat messages. |
| spelling | An API for running server-side spelling checking on Overleaf documents. |
Overleaf Docker Image
This repo contains two dockerfiles, Dockerfile-base, which builds the
sharelatex/sharelatex-base image, and Dockerfile which builds the
sharelatex/sharelatex (or "community") image.
The Base image generally contains the basic dependencies like wget and
aspell, plus texlive. We split this out because it's a pretty heavy set of
dependencies, and it's nice to not have to rebuild all of that every time.
The sharelatex/sharelatex image extends the base image and adds the actual Overleaf code
and services.
Use make build-base and make build-community to build these images.
We use the Phusion base-image
(which is extended by our base image) to provide us with a VM-like container
in which to run the Overleaf services. Baseimage uses the runit service
manager to manage services, and we add our init-scripts from the ./runit
folder.
Contributing
Please see the CONTRIBUTING file for information on contributing to the development of Overleaf. See our wiki for information on setting up a development environment and how to recompile and run Overleaf after modifications.
