- Deployed at https://tfl.iapps365.com/.
- Uses tfl.gov.uk public APIs to bootstrap and provide status updates.
- Developed as a hobby project in a handful of hours to explore the TFL APIs.
- Go backend with ~zero external dependencies.
- Web front end. Pure HTML and CSS. No javascript.
- Responsive UI thanks to Bootstrap v5.0
- Built as a docker image using Buildpacks. See Makefile.
- Build using
make build. - Binary pushed to Dockerhub.
- Binary size: 38MB. All resources including HTML & CSS bundled into the binary using
go:embed. See main.go. - Deploy as you would any stateless container.
- Line APIs
- Vehicle APIs
- For exact APIs used look at tfl-api.go.
- TFL real-time updates are very good, but not great. Maybe they can be married with timetable data.
- There doesn't seem to be a straightforward way to track a journey.
- Vehicle tracking is the closest; but it's jumpy and flaky.
- If anyone has better ideas please drop me a note or submit a pull request.
