Asymptote Web Application

This application is designed to provide a convenient way for Asymptote language users to create vector graphics remotely without any local installation.

Installation

Pre-Application Install

First install Node.js.

Application Installation

1. We recommend running this application as a non-privileged user "asymptote" on a virtual machine.

2. Disable logins:

   passwd -d asymptote

3. Install the latest version of Asymptote on the system.

4. Starting as a user belonging to the asymptote group, install the node modules and application dependencies:

   cd ~asymptote
   git clone https://github.com/vectorgraphics/asymptote-server
   cd asymptote-server
   su
   su asymptote
   make
   exit
   exit

5. We recommend running the bash script

   pruneClients 1800

   as a cronjob at regular intervals to clean up disconnected sessions; the argument specifies the number of seconds after the last ping at which the client is considered disconnected and its workspace is deleted. By default, pings are sent from active clients to the server every 600 seconds.

Running the Application

There are two modes for running this application:

1. Running the full application: To run the full application run the following commands

   cd ~asymptote/asymptote-server
       sudo make run

   Root priviledges are dropped once the application is listening on port 80. The application can then be accessed on

   http://localhost:80

2. Running only the front-end part of the application: This mode is mainly used for development of the GUI to test the CSS and Javascript code. No communication can be made to the server in this mode. To launch the application in this mode on a localhost service:

   cd ~asymptote/asymptote-server
   make frontend
