Moodle 2.3, 2.4
Released: Tuesday, May 6, 2014, 10:26 PM


This is a module, which integrates etherpad-lite in Moodle 2.3 - 2.4


  • Add / View / Delete Pads
  • Users have the same name & writing color in all pads
  • Moodle Import / Export support
  • optional guest allowance
  • It supports etherpad-lite servers, which can only be accessed through the API (access only through Moodle)
  • It can check the HTTPS certificate of the ep-lite server for full security (man in the middle attacks)


You need an etherpad-lite server, which is running on at least the same 2nd-level-domain as your moodle server.

On the github page you'll find all information you need, to install the server:

We recommend to use the etherpad-lite version 1.2.7

It's also recommended to use the latest stable release of nodejs (

we are using nodejs 0.6.12, installed over apt-get for our productive server. But we test new ep-lite versions always with this node version, before updating productive

When you want, that the server is only accessible via Moodle, then i recommend to install ep_remove_embed over the ep-lite admin interface. This removes the embed link.
To access the admin area, uncomment the user section in settings.json

Working ep-lite installation

  • Ubuntu 12.04
  • apt-get nodejs, npm, git, nginx, abiword, make, g++
  • etherpad-lite from git (v1.2.7)
  • ep-lite settings.json:
    • "requireSession":true
    • "editOnly":true
    • "abiword": "/usr/bin/abiword"
  • ep-lite plugin: ep_remove_embed via admin interface
  • upstart script
  • logrotate
  • nginx as reverse proxy with https


  1. Copy this repository to the moodle subfolder: mod/etherpadlite

  2. open your admin/index.php page and follow the instructions


  1. Server Url from your etherpadlite server Make sure, that your moodle server can access this URL
  2. ApiKey: this is stored in the file: APIKEY.txt on your etherpadlite server
  3. Padname: this is optional and maybe just for debugging the databse
  4. Cookie Domain: Enter the domain as described
  5. Session elapse time: How long should one session be valid?
  6. Https Redirect: This redirects moodle to https, so that the user feels secure
    (later this should be used to delete sessions on the etherpadlite server)
  7. Verify HTTPS cert: This lets curl check, if the https cert of the etherpadlite server is valid, to prevent man in the middle attacks
  8. Guests allowed to write?: As described

tested with Moodle 2.3-2.4
