async_mvg_api 0.2.3

No project description provided

Unofficial MVG api

An async and sync wrapper for the MVG endpoints, with data validation over pydantic

Breaking Changes

between version 0.1.5 and 0.2.0 the api has changed a lot. The api is now split into versions. The old api is available under mvg_api.v1 and the new api is available under mvg_api.v2.

Features

• Sync and async support: You can use this wrapper to make API calls synchronously or asynchronously based on your needs. It provides flexibility and allows you to leverage the benefits of both approaches.

• Pydantic schema validation: The wrapper integrates with Pydantic, a powerful data validation and parsing library, to validate API responses against predefined schemas. This ensures that the received data conforms to the expected structure and types. For every API endpoint, there is a corresponding Pydantic schema that defines the expected structure of the response. If the response does not match the schema, an exception is raised. And you allways know what data you get.

Installation

Install it over pip or from source by cloning the repository and installing the dependencies with poetry.

pip install async-mvg-api

or

git clone https://github.com/Plutokekz/MVG-Api.git
cd MVG-Api
poetry install

Usage

With the endpoint changes from MVG the api is now split into versions. Currently, there are two versions available. The first version is the old api, which is still available and work, but I think in the future it may stop working and will be removed.

The second version is the new api, which is still in beta, should work until MVG changes there endpoints one again.

Example with the v2 api

Sync

from mvg_api.v2.mvg import SyncMVG
mvg = SyncMVG()
location = mvg.get_location("Hauptbahnhof")

Async

from mvg_api.v2.mvg import AsyncMVG
import asyncio
mvg = AsyncMVG()
location = asyncio.run(mvg.get_location("Hauptbahnhof"))

the location from sync and async should look somthing like this:

LocationList(
    locations=[
        Location(
            globalId='de:09162:6',
            type=<LocationType.STATION: 'STATION'>,
            latitude=48.14003,
            longitude=11.56107,
            divaId=6,
            place='München',
            name='Hauptbahnhof',
            hasZoomData=True,
            tariffZones='m',
            aliases='Hbf München main station central station Muenchen Munchen HU HO HUHO',
            transportTypes=[
                'UBAHN',
                'TRAM',
                'SBAHN'
                ],
            surroundingPlanLink='HU'
            ),
            ...
        ]
    )

Example with the v1 api

Sync

from mvg_api.v1.mvg import MVG
mvg = MVG()
location = mvg.get_location("Hauptbahnhof")

Async

from mvg_api.v1.mvg import AsyncMVG
import asyncio
mvg = AsyncMVG()
location = asyncio.run(mvg.get_location("Hauptbahnhof"))

the location from sync and async should look somthing like this:

LocationList(
    locations=[
        Location(
            globalId='de:09162:6',
            type=<LocationType.STATION: 'STATION'>,
            latitude=48.14003,
            longitude=11.56107,
            divaId=6,
            place='München',
            name='Hauptbahnhof',
            hasZoomData=True,
            tariffZones='m',
            aliases='Hbf München main station central station Muenchen Munchen HU HO HUHO',
            transportTypes=[
                'UBAHN',
                'TRAM',
                'SBAHN'
                ],
            surroundingPlanLink='HU'
            ),
            ...
        ]
    )
