Cycling Up API

API for bicycle infrastructure dashboard, created for Brussels Mobility. The API fetches and processes raw data, as well as data fetched from Mobigis, and provides a way to access this data.

Specific routes, their paramters and return types can be found in the documentation, which is accessed by following the trivial route: /

Getting started

Installing and running locally

The API can be run in Python on your local operating system for develompent and debugging purposes.

Prerequisites are:

• python 3 https://www.python.org/download/releases/3.0/
• pipenv https://docs.pipenv.org/

Run the following commands from the cycling-up-backend directory:

$ pipenv install --dev && pipenv shell   # Install pipenv packages
$ cp .env.example .env                   # Add the .env file
$ python3 process/__init__.py            # Initialize required data
$ python3 app.py                         # Start the embedded Flask server

Now the API can be accessed at http://localhost:5000

Installing and running with Docker

You can build the application as a Docker image and run it:

• using the start.sh script

$ bash start.sh

• or manually

$ docker build --tag cycling-up-api .
$ docker run -it -p 5005:5000 --rm cycling-up-api

Now the API can be accessed at http://localhost:5005
