This app is supposed to work on the two latest Nextcloud versions.

Install latest release

You can download and install the latest release from the Nextcloud app store

Install from git

If you want to run the latest development version from git source, you need to clone the repo to your apps folder:

git clone
cd deck
make install-deps
make build

Please make sure you have installed the following dependencies: make, which, tar, npm, curl, composer

Install the nightly builds

Instead of setting everything up manually, you can just download the nightly build instead. These builds are updated every 24 hours, and are pre-configured with all the needed dependencies.

Performance limitations

Deck is not yet ready for intensive usage. A lot of database queries are generated when the number of boards, cards and attachments is high. For example, a user having access to 13 boards, with each board having on average 100 cards, and each card having on average 5 attachments, would generate 6500 database queries when doing the file related queries which would increase the page loading time significantly.

Improvements on Nextcloud server and Deck itself will improve the situation.


Nextcloud environment

You need to setup a development environment of the current nextcloud version. You can also alternatively install & run the nextcloud docker container. After the finished installation, you can clone the deck project directly in the /[nextcloud-docker-dev-dir]/workspace/server/apps/ folder.


Nothing to prepare, just dig into the code.


This requires at least Node 16 and npm 7 to be installed.

Deck requires running a make build-js to install npm dependencies and build the JavaScript code using webpack. While developing you can also use make watch to rebuild everytime the code changes.

Hot reloading

Enable debug mode in your config.php 'debug' => true,

Without SSL:

npx webpack-dev-server --config \
    --public localhost:3000 \
    --output-public-path 'http://localhost:3000/js/'

With SSL:

npx webpack-dev-server --config --https \
    --cert ~/repos/nextcloud/nc-dev/data/ssl/nextcloud.local.crt \
    --key ~/repos/nextcloud/nc-dev/data/ssl/nextcloud.local.key \
    --public nextcloud.local:3000 \
    --output-public-path 'https://nextcloud.local:3000/js/'

Running tests

You can use the provided Makefile to run all tests by using:

make test
