This service fetches the latest OV-fiets data and makes it available via a REST API.
It pulls data from OpenOV, but with a few perks over directly using http://fiets.openov.nl/locaties.json:
- Is hosted over HTTPS
- Automatically removes outdated entries
- Half its size because it only hosts info needed for overviews + a detail link
- Data is delivered as a simple array, instead of a map with IDs
Also, OpenOV isn’t thrilled about heavy traffic on their JSON (they provide open data, not hosting). They’d rather you use the ZeroMQ service bus and host it yourself, which is exactly what this project does.
This is designed to be hosted as easlily as possible, while reducing hosting costs to zero when possible. That's why Google Cloud is chosen: services like AWS also have a free tier, but after a year you have to pay. This restriction doesn't apply for Google Cloud. No guarantees, but hosting this should cost below €0,50 each month
Hosting is really easy: after setting up Google Cloud, you only need to do a terraform apply and a completely working backend will be deployed.
For this, I've created the project OvFietsUptimeChecker. This regularly checks both that the call is up, as well as that the data is up-to-date.
This backend is used by cristan/OvFietsBeschikbaarheidApp.
Happy hosting!
