react-forecast-query

A simple higher order component capable of injecting weather information from open weather api into a component

Example of use

<div>
    <input value={state.value} onInput={e => this.setState({ value: (e.target as HTMLInputElement).value })} />
    <button onClick={() => this.setState(prevState => ({ apiKey: prevState.value }))}>Test component</button>
    {state.apiKey && (
        <WeatherDisplay 
            apiKey={state.apiKey}
            label="Cloudy weather measurements"
            query={['clouds', 'cloudy']}
            by="hour"
            loadingComponent={() => <div>Loading...</div>}
            setup={forecast => forecast
                .at(today, fourDaysFromNow)
                .around(50.08804, 14.42076)
                .units('metric')
                .language('cz')}
        />
    )}
</div>

Example of how to define injected component

import React, { FunctionComponent } from "react";
import { InjectedForecastResults } from "react-forecast-query";
import weatherEnhancer from "react-forecast-query";

export interface WeatherDisplayProps {
    label: string;
}

const WeatherDisplay: FunctionComponent<WeatherDisplayProps & InjectedForecastResults> = props => (
    <section>
        <label>{props.label}</label>
        <ul>
            {props.data.clouds?.map(clouds => (
                <li>
                    {clouds.date.toDateString()} {clouds.date.toTimeString()} - {clouds.value}
                </li>
            ))}
        </ul>
        <ul>
            {props.data.cloudy?.map(weather => (
                <li>
                    <img src={props.forecast.icon(weather.icon)} />
                    <div>
                        {weather.description}
                    </div>
                </li>
            ))}
        </ul>
    </section>
);

export default weatherEnhancer(WeatherDisplay);

Use of the component

Use setup props to add location, units, language and dates, then define a string list of information you want to receive.

List of information is derived from ".list()" function in forecast-query.

"By" parameter refers to how descriptive the list should be ("hour" delivers hourly weather updates, "day" daily ones).

"loadingComponent" will display whatever component you want when the api is loading information.

        return <div>Error!</div>
    }}
    geo // Try and get geolocation
    updateGeo={1} // Updates every minute
    setup={forecast => forecast
        .at(today, fourDaysFromNow)
        .units('metric') // No location setup needed
        .language('cz')}
