Overview

Nextcloud Server is a self-hosted cloud platform for storing and synchronizing files, contacts, calendars and more on a server you choose. It lets you keep your data under your own control instead of relying on a third-party cloud, and gives others controlled access to the files and folders you want to share or work on together. The server can be extended with hundreds of apps, such as Calendar, Contacts, Mail and video chat, available in the Nextcloud App Store. It includes encryption options and two-factor authentication, and it can be installed on your own hardware, run from a ready-to-use appliance, or hosted by a service provider. Nextcloud Server is released under the AGPL-3.0 license. It suits individuals, families and organizations that want a private, self-hosted alternative to commercial file-sharing and collaboration services.

Development setup 👩‍💻

  1. 🚀 Set up your local development environment
  2. 🐛 Pick a good first issue
  3. 👩‍🔧 Create a branch and make your changes. Remember to sign off your commits using git commit -sm "Your commit message"
  4. ⬆ Create a pull request and @mention the people from the issue to review
  5. 👍 Fix things that come up during a review
  6. 🎉 Wait for it to get merged!

Third-party components are handled as git submodules which have to be initialized first. So aside from the regular git checkout invoking git submodule update --init or a similar command is needed, for details see Git documentation.

Several apps that are included by default in regular releases such as First run wizard or Activity are missing in master and have to be installed manually by cloning them into the apps subfolder.

Otherwise, git checkouts can be handled the same as release archives, by using the stable* branches. Note they should never be used on production systems.

Testing your code

We use multiple test frameworks for specific areas of the code:

  • PHPUnit for PHP unit tests
  • Behat for PHP integration tests
  • Vitest for Javascript / Typescript unit tests
  • Playwright for end-to-end tests

For our end-to-end tests using Playwright you can refer to our documentation on how to debug errors and to contribute new test cases.

Tools we use 🛠

Helpful bots at GitHub :robot:
  • Comment on a pull request with /update-3rdparty to update the 3rd party submodule. It will update to the last commit of the 3rd party branch named like the PR target.
