The ownCloud Contacts app provides a feature-rich web interface for managing CardDAV contacts in ownCloud Server. It is the frontend for the server-integrated CardDAV backend, replacing the original contacts app. Users can create, edit, and organize contacts, manage address books, and share contacts with other users.
Contacts is an app for ownCloud Server (Classic). It uses the CardDAV backend built into ownCloud Server core. The app is available on Docker Hub as part of the ownCloud Server image.
Follow the steps below to build and install the Contacts app.
The app can be built using the provided Makefile:
makeThis requires: make, which, tar, curl, npm.
Extract the build artifact in the apps/ folder of your ownCloud Server installation, then enable the app.
make testThis runs both PHP unit tests and JavaScript tests.
