This tool was written for handling restricted access during the COVID-19 pandemic and to support the booking of working spaces per location for clients.
It supports:
- different resources, e.g. locations, floors, each with their own possible capacity numbers
- different time slots per resource
- display of a configurable date range
- booking limits per user
- a rolling opening for new bookings (which is the current date + a configurable value from configuration)
This tool might not work for you out-of-the-box!
Due to the tight schedule, we were not able to turn it into a full-featured and polished shiny end product. Especially the authentication system is tailored to serve the needs of our institution. The underlying framework - Laravel - makes it pretty easy though to roll your own authentication or even go with the built-in solution. See "Authentication" for details.
Also, some things in the JavaScript part are a bit cumbersome and there should be some more cleanup in files and code structure.

- PHP 7.2
- Database
- npm
- the will and time to adjust some things ;)
Entry point for the application is public/index.php. Your webserver config should point to this location.
In order to use the introduced locations in version 1.1, you have to add your
- locations
- resources
- time slots
via administration and then run php artisan platzbuchung:upgrade from the application root path.
First you install the application by running: composer install.
You will then need to add an .env file with your configuration. A boilerplate config file is provided as .env.example. Just do a simple cp .env.example .env and tweak it to your needs.

After setting everything up, do this:
php artisan key:generate
php artisan jwt:secret
php artisan migrate
npm install
npm run prod
We query an external webservice for authentication via TLS-secured CURL. Due to GDPR we only save the user data that is absolutely needed for running the application in the application database. Custom authentication drivers are
- app/Auth/AlmaUserProvider.php
- app/Auth/PaiaUserProvider.php (contributed by Tobias Zeumer)
Chances are big that you'll use another road here. Laravel framework provides a convenient way for adding custom-tailored authentication which is described here.
Even Shibboleth authentication is possible. We've already done it successfully in the past and in another project with this library.
You could also use the built-in authentication system with local database tables as the main source. This even provides scaffolding so you should be ready to go in no time.
- In .env, set
AUTH_METHODto 'eloquent' - You will need to put back the password field to the users table (which we removed). Just create a new migration:
This creates a new file inside database/migrations directory, where you put the following:
php artisan make:migration add_password_to_users[...] public function up() { Schema::table('users', function (Blueprint $table) { $table->string('password'); }); } [...] public function down() { Schema::table('users', function (Blueprint $table) { $table->dropColumn('password'); }); } - Check out the documentation for scaffolding
The frontend is written in Vue2, a reactive JavaScript framework which interacts via API methods with the Laravel backend.
- The entry point for development is resources/js/app.js
- After compilation you have one target file: public/js/app.js
The styles are written in SASS, a CSS pre-processor.
- The entry point for development is resources/sass/app.scss
- After compilation you have one target file: public/css/app.css
Fire up the following command:
npm run [dev/prod]
The dev option compiles the files to rather verbose target versions. The prod option generates minified target versions for better performance.
For convenient development you can also use npm run watch which detects changes on the source files and compiles it on-the-fly.
Your logo should go to public/images. We use a SVG version for better scaling. After placing your logo file you have to reference it in the .envfile with the APP_LOGOoption.
All texts are defined in in form of a PHP array.
- German: resources/lang/de/app.php
- English: resources/lang/en/app.php.
But: There is currently no switcher in the frontend. You can switch the language app-wide in
config/app.php with the config option lang.
Since the frontend also relies on these you have to run the following after making adjustments to the texts:
php artisan vue-i18n:generate
npm run prod
There are 2 screens prepared for usage on dedicated screens:
- <YOUR_APPLICATION_URL>/checkin/<LOCATION_UID>
- <YOUR_APPLICATION_URL>/checkout/<LOCATION_UID>
In our institution they run in 2 workstations with kiosk browser installed and a hand scanner attached which scans the barcode of the library card. Of course, The screens can also be used on a regular helpdesk computer in a browser, operated by a staff member.
The check-in validates if there is a currently valid booking present. The check-out validates if there was an check-in before.
There is an administration panel available for configured users. For now, you have to alter the
database user record and set the is_admin column value to true. The admin area is then available via <APP_DOMAIN>/#/admin/locations.
In a future release, it will be included in the navigation for configured users.
The booking system relies on
- Location(s)
- Resources within each location
- Time slots within each resource for each day
This allows for granular access control. You start with the locations and then progress to resources and time slots.
You can date-constraint time slots to support successive extension of opening times.
You can also specify closings: Single dates or date ranges are possible.
There are several logs to consult:
- Application log: storage/logs/laravel.log
- Authentication log: storage/logs/auth.log
- Booking log: storage/logs/booking.log
- Checkin/Checkout log: storage/log/checkin.log
In case of a COVID-19 infected client or a zombie apocalypse, this is the command to run:
php artisan platzbuchung:user-report <LOCATION_UID> <DATE>
In our case, it assembles a separated list of checked-in users for a given location UID (e.g. 'zb', see administration) and a given date from the application database which is then sent to another server for enrichment with other personal data (which we don't store due to privacy reasons). Check out app/Console/Commands/GenerateUserReport.php for adjustments.
php artisan platzbuchung:daily-stats <LOCATION_UID> <DATE>
Uses the internal scheduler. Uses the given location UID (e.g. 'zb', see administration) and the given date or, if omitted, the current date. Sends a mail to the configured recipient(s), see above. Best used with a cron job like this:
* * * * * cd /your/application/directory && php artisan schedule:run >> /dev/null 2>&1
The command frequency can be configured here: app/Console/Kernel.php.
If you have your location(s) and the accompaning resource(s) ready you can add time slots in batch mode. Pretty conveniet for larger edit and much faster than going through the admin GUI.
php artisan platzbuchung:add-timeslots
You'll interactively get asked several questions to add your time slots as you need them.
php artisan platzbuchung:cleanup-userdata
Uses the internal scheduler. Vacuums the database and deletes
- bookings with deletion date older than 30 days
- users with last login older than 30 days
Best used with a cron job like this:
* * * * * cd /your/application/directory && php artisan schedule:run >> /dev/null 2>&1
The command frequency can be configured here: app/Console/Kernel.php.
- Auto delete of checkins an booking data after x weeks
- Webpack optimizations for smaller frontend asset files
- Docker version
