Plugins

Etherpad is very customizable through plugins.

Available Plugins

For a list of available plugins, see the plugins site.

Plugin Installation

You can install plugins from the admin web interface (e.g., http://127.0.0.1:9001/admin/plugins).

Alternatively, you can install plugins from the command line:

cd /path/to/etherpad-lite
pnpm run plugins i ep_${plugin_name}

Also see the plugin wiki article.

Suggested Plugins

Run the following command in your Etherpad folder to get all of the features visible in the above demo gif:

pnpm run plugins i \
  ep_align \
  ep_comments_page \
  ep_embedded_hyperlinks2 \
  ep_font_color \
  ep_headings2 \
  ep_markdown \
  ep_webrtc

For user authentication, you are encouraged to run an OpenID Connect identity provider (OP) and install the following plugins:

• ep_openid_connect to authenticate against your OP.
• ep_guest to create a "guest" account that has limited access (e.g., read-only access).
• ep_user_displayname to automatically populate each user's displayed name from your OP.
• ep_stable_authorid so that each user's chosen color, display name, comment ownership, etc. is strongly linked to their account.

Upgrade Etherpad

Run the following command in your Etherpad folder to upgrade

1. Stop any running Etherpad (manual, systemd ...)
2. Get present version

git -P tag --contains

3. List versions available

git -P tag --list "v*" --merged

4. Select the version

git checkout v2.2.5
git switch -c v2.2.5

5. Upgrade Etherpad

./bin/run.sh

6. Stop with [CTRL-C]
7. Restart your Etherpad service

Next Steps

Tweak the settings

You can modify the settings in settings.json. If you need to handle multiple settings files, you can pass the path to a settings file to bin/run.sh using the -s|--settings option: this allows you to run multiple Etherpad instances from the same installation. Similarly, --credentials can be used to give a settings override file, --apikey to give a different APIKEY.txt file and --sessionkey to give a non-default SESSIONKEY.txt. Each configuration parameter can also be set via an environment variable, using the syntax "${ENV_VAR}" or "${ENV_VAR:default_value}". For details, refer to settings.json.template. Once you have access to your /admin section, settings can be modified through the web browser.

If you are planning to use Etherpad in a production environment, you should use a dedicated database such as mysql, since the dirtyDB database driver is only for testing and/or development purposes.

Secure your installation

If you have enabled authentication in users section in settings.json, it is a good security practice to store hashes instead of plain text passwords in that file. This is especially advised if you are running a production installation.

Please install ep_hash_auth plugin and configure it. If you prefer, ep_hash_auth also gives you the option of storing the users in a custom directory in the file system, without having to edit settings.json and restart Etherpad each time.

Customize the style with skin variants

Development

Things you should know

You can debug Etherpad using bin/debugRun.sh.

You can run Etherpad quickly launching bin/fastRun.sh. It's convenient for developers and advanced users. Be aware that it will skip the dependencies update, so remember to run bin/installDeps.sh after installing a new dependency or upgrading version.

Contributing

Read our Developer Guidelines

HTTP API

Etherpad is designed to be easily embeddable and provides a HTTP API that allows your web application to manage pads, users and groups. It is recommended to use the available client implementations in order to interact with this API.

OpenAPI (previously swagger) definitions for the API are exposed under /api/openapi.json.

jQuery plugin

There is a jQuery plugin that helps you to embed Pads into your website.

Plugin Framework

Etherpad offers a plugin framework, allowing you to easily add your own features. By default your Etherpad is extremely light-weight and it's up to you to customize your experience. Once you have Etherpad installed you should visit the plugin page and take control.

Translations / Localizations (i18n / l10n)
