Mapbox (HTML)

Create Mapbox GL JS maps that load data from UDF HTTP endpoints.

You'll first generate a signed UDF URL and render it on an HTML map. You can then use the HTML map in a low-code app like Retool or render it as an iframe in an app such as Notion.

1. Generate a signed URL for a UDF​

First, create a UDF and generate an HTTP endpoint.

2. Create a Mapbox HTML map​

Create an .html file following this template. This code creates a mapbox map, adds a source, and then a layer that renders data from that source. Supported layer types are:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Add a vector tile source</title>
<meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no">

    const map = new mapboxgl.Map({
        container: 'map',
        // Choose from Mapbox's core styles, or make your own style with Mapbox Studio
        style: 'mapbox://styles/mapbox/dark-v10',
        zoom: 13,
        center: [-122.447303, 37.753574]
    });

    // Optionally, pass parameters to the tile source
    const model = {
        theme: 'building'
    }

    map.on('load', () => {
        map.addSource('fused-vector-source', {
            'type': 'vector',
            'tiles': [ // Vector Tile URL that returns mvt (https://docs.mapbox.com/data/tilesets/guides/vector-tiles-standards/)

        map.addLayer(
            {
                'id': 'fused-vector-layer', // Layer ID
                'type': 'line',
                'source': 'fused-vector-source', // ID of the tile source created above
                'source-layer': 'udf', // Important! The source-layer name is 'udf' for all Fused vector tiles
                'layout': {
                    'line-cap': 'round',
                    'line-join': 'round'

                    'line-width': 2
                }
            }
        );
    })

Vector Tile layers​

Use the following snippet to create a vector layer. The layer in the sample map comes from Overture Buildings UDF.

info

When rendering mvt data types, Mapbox may clip features that exceed the bounds of the tile. A workaround is for the UDF to clip the output at the bbox bounds or to only return features within the bbox. See Discord thread for more information.

<script>
    map.addSource('fused-vector-source', {
        'type': 'vector',
        'tiles': [ // Vector Tile URL that returns mvt (https://docs.mapbox.com/data/tilesets/guides/vector-tiles-standards/)
            `https://www.fused.io/server/v1/realtime-shared/55ffe996fc2bd635cde3beda7e2632005e228798a1ef333297240b86af7d12a4/run/tiles/{z}/{x}/{y}?dtype_out_vector=mvt&type=${model.theme}`
        ],
        'minzoom': 6,
        'maxzoom': 14
    });
    map.addLayer(
        {
            'id': 'fused-vector-layer', // Layer ID
            'type': 'line',
            'source': 'fused-vector-source', // ID of the tile source created above
            'source-layer': 'udf', // Important! The source-layer name is 'udf' for Fused vector tiles
            'layout': {
                'line-cap': 'round',
                'line-join': 'round'
            },
            'paint': {
                'line-opacity': 0.6,
                'line-color': 'rgb(53, 175, 109)',
                'line-width': 2
            }
        }
    );
</script>

Raster Tile layers​

Use the following snippet to create a raster layer. The layer in the sample map comes from the Solar Irradiance UDF.

<script>
    map.addSource('fused-irradiation-source', {
        'type': 'raster',
        'tiles': [ // Raster Tile URL that returns png
            'https://www.fused.io/server/v1/realtime-shared/af0bc71e64075233b731f316988b323ac28658059db9e87388393fe187752501/run/tiles/{z}/{x}/{y}?dtype_out_raster=png'
        ],
        'tileSize': 256,
        'minzoom': 10,
        'maxzoom': 18
    });
    map.addLayer(
        {
            'id': 'wms-test-layer',
            'type': 'raster',
            'source': 'fused-irradiation-source',
            'paint': {}
        },
        'building' // Place layer under labels, roads and buildings.
    );
</script>
