Tiny webapp that takes your location and shows you the three closest cars that need refuelling (so you can earn bonus minutes). This works for DriveNow, Car2Go and Multicity.
Also shown are the nearest tank stations (or electro charging stations) where the car can be refilled.
Unfortunately since the applink options for DriveNow aren't clear or obvious, the reserve link will only open the DriveNow app but doesn't link directly to the car.
Car2Go has far better deeplinks, making reservation far simpler. Unfortunately you only get 10 bonus minutes, so it's actually hardly worth the effort (at least in Berlin).
You'll need a google api key for the maps and the drive now api key that is the same for everyone.
For the google api key, you'll need to enable the maps api and the directions api.
Since this app uses various services of google, you'll need to enable the following services for the API token/key:
- Google Maps Time Zone API
- Google Maps Javascript API
- Google Maps Directions API
Otherwise app won't work!
All cities for DriveNow, Car2Go and Multicity are supported. The exact city is determined by your location, so this will work even if you're in the middle of nowhere!
Since there isn't an "official" API from DriveNow, this code will fail if
- DriveNow decides to block the requests coming from the backend server (which they already do for servers located in Amazon Europe).
- DriveNow decides to change their API, i.e. make it more restrictive.
So this might fail without warning.
They have a very good description, including applinks (aka deeplinks).
Car2Go does not accept third parties any longer. So to obtain their key, a similar approach as free2move is required: persistence.
Since DriveNow did indeed shutdown their API (or rather made it far more difficult to access it), we now use Free2Moves' API (which is also, unfortunately, liable to change at any moment).
For this, the CARJUMP_SECRET environment variable has to be set. To
obtain this key, a certain amount of persistence is required.
You will need to obtain API keys for all the above services, else locally the application will not work. See docker-compose.yaml to see what is required.
Then install Docker and then do the following:
docker-compose build
docker-compose up
Then you can access the application:
open -a Firefox http://localhost:3001
If you want to setup a SSL certificate (which is a good idea), then you can use let's encrypt to get a free ssl certificate.
Follow this guide to find out what needs to be done.
To provide the correct response, you'll need to setup two (or more) environment variables at heroku. These are:
ACME_KEY[domain]=xxx
ACME_TOKEN[domain]=yyy
where domain can be anything as long as they match and KEY
is the response for the TOKEN. Example using the data found
in the guide:
ACME_KEY[ONE]=ya6k1edW38z-your-value-here
ACME_TOKEN[ONE]=ya6k1ed-SOME-LONG-URL
You might need multiple key/token pairs, one for which domain that you need a certificate for. For example, tankmeister.de and www.tankmeister.de are two different domains, hence two key/token pairs.
