Adding plugins (DEB/RPM packages)

A number of plugins exist for use with OpenProject. Most plugins that are maintained by us are shipping with OpenProject, however there are several plugins contributed by the community.

Previously, using them in a packaged installation was not possible without losing your changes on every upgrade. With the following steps, you can now use third party plugins.

Add a custom Gemfile

If you have a plugin you wish to add to your packaged OpenProject installation, create a separate Gemfile with the Gem dependencies, such as the following:

group :opf_plugins do
  gem 'openproject-emoji', git: 'https://github.com/tessi/openproject-emoji.git', :branch => 'op-5-stable'
end

The group :opf_plugins is generally recommended, but only required for plugins with custom frontend code that is picked up by webpack and output into their respective bundles.

We suggest to store the Gemfile under /etc/openproject/Gemfile.custom, but the choice is up to you, just make sure the openproject user is able to read it.

Propagate the Gemfile to the package

You have to tell your installation to use the custom gemfile via a config setting:

openproject config:set CUSTOM_PLUGIN_GEMFILE=/etc/openproject/Gemfile.custom

If your plugin links into the Angular frontend, you will need to set the following environment variable to ensure it gets recompiled. Please note that NPM dependencies will be installed during the installation, and the angular CLI compilation will take place which will delay the configuration process by a few minutes.

openproject config:set RECOMPILE_ANGULAR_ASSETS="true"

Re-run the installer

To re-bundle the application including the new plugins, as well as running migrations and precompiling their assets, simply re-run the installer while using the same configuration as before.

openproject configure

Using configure will take your previous decisions in the installer and simply re-apply them, which is an idempotent operation. It will detect the Gemfile config option being set and re-bundle the application with the additional plugins.
