travelynx - Railway Travel Logger
travelynx allows checking into and out of individual trains, thus providing a log of your railway journeys annotated with real-time delays and service messages. At the moment, it only supports german railways and trains which are exposed by the Deutsche Bahn IRIS Interface.
- perl >= 5.20
- carton or cpanminus
travelynx depends on a set of Perl modules which are documented in
After installing the dependencies mentioned above, you can use carton or
cpanminus to install Perl depenencies locally.
In the project root directory (where
cpanfile resides), run either
cpanm --installdeps .
PERL5LIB=.../local/lib/perl5 before executing any travelynx
commands (see configs in the examples directory) or wrap them with
carton exec, e.g.
carton exec hypnotoad index.pl
First, you need to set up a PostgreSQL database so that travelynx can store user accounts and journeys. It must be at least version 9.4 and must use a UTF-8 locale. The following steps describe setup on a Debian 9 system; setup on other distributions should be similar.
- Write down a strong random password
- Create a postgres user for travelynx:
sudo -u postgres createuser -P travelynx(enter password when prompted)
- Create the database:
sudo -u postgres createdb -O travelynx travelynx
examples/travelynx.confto the application root directory (the one in which
index.plresides) and edit it. Make sure to configure db, cache, mail, and secrets.
- Initialize the database:
carton exec perl index.pl database migrateor
PERL5LIB=local/lib/perl5 perl index.pl database migrate
Your server also needs to be able to send mail. Set up your MTA of choice and make sure that the sendmail binary can be used for outgoing mails. Mail reception on the server is not required.
Finally, configure the web service:
- Set up a travelynx service using the service supervisor of your choice
examples/travelynx.servicefor a systemd unit file)
- Configure your web server to reverse-provy requests to the travelynx
examples/nginx-sitefor an nginx config.
- Install a
timeout 5m perl index.pl work -m productioncronjob. It is used to update realtime data and perform automatic checkout and should run every three minutes or so, see
You can now start the travelynx service, navigate to the website and register your first account. There is no admin account, all management is performed via cron or (in non-standard cases) on the command line.
It is recommended to run travelynx directly from the git repository. When updating, the workflow depends on whether schema updates need to be applied or not.
git pull chmod -R a+rX . # only needed if travelynx is running under a different user if perl index.pl database has-current-schema; then systemctl reload travelynx else systemctl stop travelynx perl index.pl database migrate systemctl start travelynx fi
Note that this is subject to change -- the application may perform schema
updates automatically in the future. If you used carton for installation,
carton exec perl ... in the snippet above; if you used cpanm, export
For the sake of this manual, we will assume your travelynx instance is running
travelynx journey logging is based on checkin and checkout actions: You check into a train when boarding it, select a destination, and are automatically checked out when you arrive. Real-time data is saved on both occasions and continuously updated while in transit, providing an accurate overview of both scheduled and actual journey times.
You can check into a train up to 30 minutes before its scheduled departure and up to two hours after its actual departure (including delays).
First, you need to select the station you want to check in from.
travelynx.de or click/tap on the travelynx text in the navigation
bar. You will see a list of the five stations closest to your current location
(as reported by your browser). Select the station you're at or enter its
name or DS100 code manually.
As soon as you select a train, you will be checked in and travelynx will switch to the journey / checkout view. If you already know where you're headed, you should click/tap on the destination station in the station list now. You can change the destination by selecting a new one anytime.
You are automatically checked out a few minutes after arrival at your destination. If the train has already arrived when you select a destination and its arrival was less than two hours ago, you are checked out immediately. If it's more than two hours, you need to perform a manual checkout (without arrival data) using the link at the bottom of the checkin menu's station list.
The test scripts assume that travelynx.conf contains a valid database connection. They will create a test-specific schema, perform all operations in it, and then drop the schema. As such, the database specified in the config is not affected.
Nevertheless, bugs may happen. Do NOT run tests on your production database. Please use a separate development database instead.
Run the tests by executing
prove -v for debug output and
DBI_TRACE=SQL prove -v to monitor SQL queries.
