Asynchronous client for the Open-Meteo API.

## About

Open-Meteo offers free weather forecast APIs for open-source developers and
non-commercial use. No API key is required. You can start using it immediately!

## Installation

```bash
pip install open-meteo
```

## Usage

```python
import asyncio

from open_meteo import OpenMeteo
from open_meteo.models import DailyParameters, HourlyParameters


async def main():
    """Show example on using the Open-Meteo API client."""
    async with OpenMeteo() as open_meteo:
        forecast = await open_meteo.forecast(
            latitude=52.27,
            longitude=6.87417,
            current_weather=True,
            daily=[
                DailyParameters.SUNRISE,
                DailyParameters.SUNSET,
            ],
            hourly=[
                HourlyParameters.TEMPERATURE_2M,
                HourlyParameters.RELATIVE_HUMIDITY_2M,
            ],
        )
        print(forecast)


if __name__ == "__main__":
    asyncio.run(main())
```

## Changelog & Releases

This repository keeps a change log using [GitHub's releases][releases]
functionality. The format of the log is based on
[Keep a Changelog][keepchangelog].

Releases are based on [Semantic Versioning][semver], and use the format
of `MAJOR.MINOR.PATCH`. In a nutshell, the version will be incremented
based on the following:

- `MAJOR`: Incompatible or major changes.
- `MINOR`: Backwards-compatible new features and enhancements.
- `PATCH`: Backwards-compatible bugfixes and package updates.

## Contributing

This is an active open-source project. We are always open to people who want to
use the code or contribute to it.

We've set up a separate document for our
[contribution guidelines](CONTRIBUTING.md).

Thank you for being involved! :heart_eyes:

## Setting up development environment

This Python project is fully managed using the [Poetry][poetry] dependency
manager. But also relies on the use of NodeJS for certain checks during
development.

You need at least:

- Python 3.11+
- [Poetry][poetry-install]
- NodeJS 20+ (including NPM)

To install all packages, including all development requirements:

```bash
npm install
poetry install
```

As this repository uses the [pre-commit][pre-commit] framework, all changes
are linted and tested with each commit. You can run all checks and tests
manually, using the following command:

```bash
poetry run pre-commit run --all-files
```

To run just the Python tests:

```bash
poetry run pytest
```
