  • Do not throw when style contains an unsupported layer type
  • Fix rendering for zero text halo
  • Fix scaling of icon-offset
  • Allow computed values for text-tranform
  • Add support for text-ignore-placement and text-allow-overlap

12.1.1

  • Consider the icon-size layout property also for icons not provided by the stylesheet
  • Handle fractional layer minzoom and maxzoom properly when fetching source data

12.1.0

  • New 'updateMapboxSource()' utility function.
  • Accept Promise as return type for transformRequest()
  • Do not overwrite existing search param with access token

12.0.0

Backwards incompatible changes

  • The transformRequest hook is now called for every single Tiles request with the final url, instead of just once with the url template.
  • Generated OpenLayers Tile and VectorTile sources previously used the template urls obtained by source.getUrl() or source.getUrls(). Now they use a tileLoadFunction configured by ol-mapbox-style instead.
  • Generated OpenLayers Vector sources are now always configured with a loader by ol-mapbox-style. The getUrl() method will return the url without the transformRequest transform. When the url is templated ({bbox-...}), getUrl() will return undefined.

Other changes

  • The transformRequest hook now also accepts a url string as return value. When a Request is returned, it will be fully respected - not just the request's url.

  • Add getStyleForLayer() function for more efficient legend creation without recordStyleLayer(true)

10.4.0

Changes that require attention

Font handling and loading

ol-mapbox-style no longer defaults to loading Google fonts when a required font is not available. Instead, it respects the new metadata.ol:webfonts field in the Mapbox Style document. Example:

{
  "version": 8,
  "metadata": {
    "ol:webfonts": "https://mytileservergl.com/fonts/{font-family}/{fontweight}{-fontstyle}.css"
  }
  // ...
}

The supported template placeholders are

  • {font-family}: CSS font family converted to lowercase, blanks replaced with -, e.g. noto-sans
  • {Font+Family}: CSS font family in original case, blanks replaced with +, e.g. Noto+Sans
  • {fontweight}: CSS font weight (numeric), e.g. 400, 700
  • {fontstyle}: CSS font style, e.g. normal, italic
  • {-fontstyle}: CSS font style other than normal, e.g. -italic or empty string for normal

In addition to providing fonts along with the style, this can be used to retrieve fonts from a CDN (e.g. @fontsource) or Google fonts. If this metadata field is not set to the style, the following default template will be used:

https://cdn.jsdelivr.net/npm/@fontsource/{font-family}/{fontweight}{-fontstyle}.css

To retain the current behavior (i.e. use Google Fonts), the template URL will have to be

https://fonts.googleapis.com/css?family={Font+Family}:{fontweight}{fontstyle}

Other changes

  • Fix a potential tile cache issue
  • Fix problem caused by getUid function missing in the full build
  • Make updateMapboxStyle() work with objects that are not a reference to the original one
  • Add support for the tms tile scheme for raster and vector layers
  • Add support for the terrarium encoding for raster-dem sources
  • Fix an issue where the icon-offset layout property modifies the underlying Mapbox Style object
  • Set the correct input projection for geojson sources when the projection option is used

10.3.4

  • Fix addMapboxLayer - updateMapboxLayer - removeMapboxLayer sequence

10.3.3

  • Fix updateMapboxLayer() and function/filter cache handling

10.3.2

  • Export removeMapboxLayer

10.3.1

  • Fix initial visibility of vector and geojson source layers

10.3.0

  • Add support for symbol-placement: "line-center"

10.2.0

  • Add support for the "id" expression

10.1.0

  • New removeMapboxLayer() function
  • Substantial fixes to the addMapboxLayer() function
  • Manage OpenLayers layer visibility based on the visibility of its Mapbox layers

10.0.0

Breaking changes

BBOX templates for geojson sources

Previously, the {bbox-epsg-3857} and {bbox-epsg-[custom projection srs code]} template replacement included the projection's SRS identifier, e.g. 1234,4567,4321,7654,EPSG:9876. Now, the template replacement just includes the bounding box. This means that e.g. WFS source URLs need to be changed in the Mapbox style.

If you previously had a source definition like

{
  "type": "geojson",
  "data": "https://ahocevar.com/geoserver/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=osm:water_areas&outputFormat=application/json&srsname=EPSG:4326&bbox={bbox-epsg-3857}"
}

you have to change it to

{
  "type": "geojson",
  "data": "https://ahocevar.com/geoserver/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=osm:water_areas&outputFormat=application/json&srsname=EPSG:4326&bbox={bbox-epsg-3857},EPSG:3857"
}

The reason for this breaking change is compatibility with OCG API Features and other services that do not accept the SRS identifier as additional BBOX parameter.

  • Simplified 3-argument signature of applyStyle(). The longer signatures continue to work, but are deprecated.

9.1.0

  • apply() can now also apply to an ol/layer/Group.
  • Backgrounds are no longer applied using OpenLayers's setBackground(), but with a prerender function for the first layer

9.0.0

Breaking changes

  • ol-mapbox-style now requires OpenLayers 7
  • icon-offset has been fixed. If you previously worked around the x-value moving left instead of right with increasing offset, you have to remove this workaround now.

Other changes

  • Added support for text-justify

8.2.1

  • Updated dependencies
  • CI changes

8.2.0

  • More secure regular expression for property templates; simplified template handling
  • Avoid unnecessary TileJSON fetches
  • New SpriteImage type for the transformRequest option

8.1.2

  • Add require field to package.json's exports to avoid ESLint complaints

8.1.1

  • Add main field to package.json to avoid ESLint complaints (was meant to go into 8.1.0 already)

8.1.0

  • Add support for icon-ignore-placement and icon-allow-overlap
  • Add main field to package.json to avoid ESLint complaints

8.0.8

  • Fix relative source url handling for GeoJSON sources
  • Fix website examples

8.0.7

  • Use rollup instead of webpack for creating bundles

8.0.6

  • Remove webfont-matcher dependency. Instead, load Google fonts only when they are not available already.
  • Normalize Arial font name to make sure it can be detected.
  • Use sans-serif as fallback font.

8.0.5

  • Do not advertise the dist/olms.js cjs bundle in package.json, because its imports from ol are not cjs compliant. This should resolve problems with old bundlers that pick the cjs bundle instead of the ejs bundle.

8.0.4

  • Add Accept: application/json header to requests for jsons. This avoids e.g. problems with Esri servers returning HTML instead of JSON
  • Reduce build size by stripping more fields from the style spec json.

8.0.3

  • Fix applyStyle() regression that broke the function when no sourceOrLayer was provided

8.0.2

  • Fix display of optional arguments in API docs
  • Fix layer stack regression when layers from one source are spread across multiple OpenLayers layers

8.0.1

  • Display API docs correctly on npmjs.com

8.0.0

Breaking changes

  • The package now provides two separate bundles for umd and ejs. dist/olms.js is the umd bundle, dist/index.js the ejs bundle. No other JavaScript files are provided in the dist/ folder any more.
  • Imports from the dist/ folder are no longer supported. They need to be replaced with imports from the package, e.g. import {stylefunction} from "ol-mapbox-style" instead of import stylefunction from "ol-mapbox-style/dist/stylefunction".
  • The apply() function has been replaced with an alias of the default export. This means that apply() now returns a Promise<Map> instead of a Map.
  • The auto-generated types are now stricter, because they reference OpenLayers types correctly, instead of using any.

Other changes

  • apply(), applyStyle() and applyBackground() now take an options argument, which can contain a transformRequest option. With that function, urls and requests for styles, sprites, tiles and data can be modified. This can be useful e.g. to fix relative urls or to add credentials.
  • Another available option is accessToken. In combination with the new support for mapbox:// urls, it has become much easier to use maps and styles from Mapbox.
  • Finally, a set of resolutions can be configured in the options. This makes it much easier to work with layers or maps in projections other than Web Mercator.
  • The applyStyle() function has become more powerful and can now create and populate the source of the provided layer.
  • feature-state is now supported. The new functions setFeatureState() and getFeatureState() can be used to set and get the feature state.
  • The build size is now at least 80 kB smaller because of pre-processing of the style specification from the @mapbox/mapbox-gl-style-spec package. The umd bundle no longer contains the OpenLayers code that has been there by accident for a few releases, which had unnecessarily increased the build size by almost 400 kB.
  • The API docs are now generated with typedoc instead of documentation.js

Breaking changes

Module paths

ol-mapbox-style now ships with transpiled modules in the dist/ folder, and sources in the src/ folder. Previously, all modules were provided in the root directory.

When upgrading, the import paths need to be checked. For example,

import stylefunction from 'ol-mapbox-style/stylefunction';

needs to be changed to

import stylefunction from 'ol-mapbox-style/dist/stylefunction';

  • Fix background opacity
  • Respect minzoom from TileJSON sources, avoiding underzooming which can lead to loading thousands of tiles

4.0.0

Breaking changes

Zoom handling

The way how we handle zoom, minzoom and maxzoom throughout the library has been reworked:

  • When ol-mapbox-style creates an ol/View instance, it will be configured with the zoom level range that mapbox-gl uses. When updating from previous versions, you will notice that the zoom levels of the OpenLayers view will now match those in the Mapbox Style object. Previously OpenLayers zoom levels were higher by 1.
  • When a Mapbox Style object is configured with a zoom, the zoom level will now be interpreted like in mapbox-gl, i.e. you will be zoomed in one level deeper than before the update.
  • minzoom and maxzoom on a Mapbox Style layer were previously determined by the tile size of the underlying source. For raster sources with a tile size of 256, this means that minzoom and maxzoom are zoomed in one level deeper than before the update. For sources with a tile size of 512, nothing changes.
  • minzoom and maxzoom on a Mapbox Style source now influence the ol/tilegrid/TileGrid that ol-mapbox-style creates for a source in a different way. The resolutions will always match mapbox-gl default zoom levels.
  • minzoom and maxzoom on Mapbox Style layers no longer influences whether the ol/layer/Layer instance is set visible at a certain resolution. Instead, the layer's maxResolution and minResolution are set.

Switch to the ol package

With version 2.x, ol-mapbox-style switched to the ol npm package for the OpenLayers dependency. Users of dist/olms.js will not notice this change. Applications that have been using the openlayers npm package should be migrated to the ol package too.

If switching to ol is not yet desired, it is still possible to use ol-mapbox-style with the openlayers package, with the help of standalonify. You have to require OpenLayers as global.ol = require('openlayers');. To build the bundle, use a command like the following:

$ node_modules/.bin/browserify -g [ babelify --plugins [ transform-es2015-modules-commonjs ] ]  -p [ standalonify --name null --deps [ null --ol/style/style ol.style.Style --ol/style/fill ol.style.Fill --ol/style/stroke ol.style.Stroke --ol/style/circle ol.style.Circle --ol/style/icon ol.style.Icon --ol/style/text ol.style.Text ] ] example/index.js > example/bundle.js

getStyleFunction moved to separate mapbox-to-ol-style package

For applications that do not need sprites and web fonts for their styles, a separate mapbox-to-ol-style package with focus on small build size and minimal dependencies has been created. ol-mapbox-style depends on that package.

If you have previously been using the getStyleFunction function, you now have to import it from mapbox-to-ol-style. If you have not used anything else from ol-mapbox-style, you can uninstall it.

Google fonts no longer need to be included in the html

ol-mapbox-style now automatically loads web fonts from Google. So in most cases, it is no longer necessary to scan the Mapbox Style for fonts and include them manually in the html of the application.
