Project Description

Nextcloud is an open source system for file sync & sharing, calendar, contacts etc. Very similar to what Dropbox or Google Suite are used for. It consists of a server component with apps for Files, Contacts, Calendar, Mail etc., a desktop client, and mobile apps for Android and iOS.


If you are interested in this project and have any project-specific questions, you can use our #nextcloud-dev IRC channel

Project's Requirements

The server part is mainly programmed in PHP, Javascript, HTML and CSS. The Android app is Java and the iOS app in Objective-C. There are a lot of different aspects to work on in Nextcloud so there’s something fitting for everyone. In general, basic experience with the technologies is already enough to get involved. The more the better, but the community will be happy to help. :) We use Git for all version control, discussions and work is done on Github, and English is the main language.

Server apps are already easy to contribute to with basic HTML+CSS skills. We use SCSS but it’s very easy to get into if you know CSS.
For tests we use PHPUnit for PHP and Karma+Jasmine for Javascript.
The separate apps/plugins are built with different technologies on the Javascript side. We are currently experimenting with moving to Vue.js but currently there are still various frameworks used. See more information in parentheses for each app:

The mobile apps:

And other parts like:

The best place to start is our IRC channel #nextcloud-dev: – our community of contributors hangs out there and will be able to help you with any questions.

To set up your local development environment, there’s documentation for Linux/Ubuntu, Windows (you need to set up a VM with Ubuntu) and macOS

And then to get started with contributing, go through the »good first issues« linked below. Best decide on one of the apps and focus on that. There’s also specific IRC channels for the apps, like #nextcloud-mail, #nextcloud-contacts, #nextcloud-talk and #nextcloud-mobile. :)

Tasks And Features

We use the "good first issue" tag so you can find small bugs and enhancements to start out with :)

Here are some examples you could tackle:
- Mail app: Ctrl-S for triggering draft save
- Mail app: Print stylesheet
- Mail app: »Retry« button on error views
- Talk app: Notify user when talking while being muted
- Good First Issues for the Android app:

Of course anything that you are missing or see as an issue and would like to work on! Either pick something from the issue tracker or propose something yourself. :)
