Maptoolkit Maps JS

This example adds the current temperature data as a fill layer to a Maptoolkit map using the Weather API vector tile source. The color ramp maps temperatures from blue (cold) to red (hot).

const API_KEY = 'YOUR_API_KEY';

    const map = new maptoolkit.Map({
        container: 'map',
        apiKey: API_KEY,
        style: `https://styles.maptoolkit.net/maptoolkit/maptoolkit.summer.json?api_key=${API_KEY}`,
        center: [13.0, 47.5],
        zoom: 5,
        attributionControl: { compact: false }
    });

    map.addControl(new maptoolkit.NavigationControl(), 'top-right');

    map.on('load', () => {
        map.addSource('weather', {
            type: 'vector',
            url: `https://weather.maptoolkit.net/vector/icon.0.json?api_key=${API_KEY}`,
        });

        const firstSymbolId = (map.getStyle().layers.find((l) => l.type === 'symbol') || {}).id;

        map.addLayer({
            id: 'weather-temperature',
            type: 'fill',
            source: 'weather',
            'source-layer': 'temperature',
            paint: {
                'fill-color': [
                    'interpolate', ['linear'], ['get', 'degree'],
                    -20, '#313695',
                    0,   '#74add1',
                    10,  '#fee090',
                    20,  '#f46d43',
                    35,  '#a50026'
                ],
                'fill-opacity': 0.6,
            },
        }, firstSymbolId);
    });

Use the prompt below with any LLM to get the same result. Make sure the Maptoolkit MCP server is connected first — check out AI Integration & MCP to get started.

Use the Maptoolkit Connector. Create a map centered on Austria and add the current temperature as a color-coded fill layer from the Weather API.
