Shot][product-screenshot]](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/styles-feature.html)\n\n\nVector Tiles Google Maps is a JavaScript library to render vector tiles in Google Maps.\n\nThe library provides funcionality to enable cache, filter features, apply styles, onclick event, mouse hover, and show/hide layers.\n\nFurther work would be to load [Mapxbox GL Styles](https://docs.mapbox.com/mapbox-gl-js/style-spec/) in Google Maps.\n\n### Built With\n\n* [Google Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/overview?)\n* [Mapbox vector tiles](https://github.com/mapbox/vector-tile-js)\n* [Protocol Buffers](https://github.com/protocolbuffers/protobuf)\n* JavaScript\n\n\n\u003c!-- DEMO EXAMPLES --\u003e\n## Examples\n\n* [Basic](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/basic.html) - Basic loading vector tiles with debug enabled.\n* [Cache](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/cache.html) - Cache enabled.\n* [Click](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/click.html) - Click to select one or multiple features.\n* [Hover](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/hover.html) - On mouse hover event.\n* [Preselected features](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/preselected-features.html) - Set features as selected before loading.\n* [Filter](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/filter.html) - Filter features by it properties.\n* [Layers](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/layers.html) - Add remove vector tiles layers.\n* [Styles](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/styles.html) - Change style dynamically.\n* [Styles feature](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/styles-feature.html) - Style based on feature properties.\n* [Style filter and layer](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/style-filter-layer.html) - Update the style, filter and visible layers simultaneously.\n* [Point, linestring and polygon](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/point-linestring-polygon.html) - Show all type of geometries.\n* [Custom draw](https://techjb.github.io/Vector-Tiles-Google-Maps/examples/custom-draw.html) - Custom draw function for each feature.\n\n\n\u003c!-- INSTALATION --\u003e\n## Installation\n\n1. Clone the repo\n   ```sh\n   git clone https://github.com/techjb/Vector-Tiles-Google-Maps.git\n   ```\n2. Install NPM packages\n   ```sh\n   npm install\n   ```\n3. Get your own API Key for the [Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/get-api-key) and replace it in all the provided examples\n   ```html\n   \u003cscript src=\"https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY\" defer\u003e\u003c/script\u003e\n   ```\n\n\n\u003c!-- USAGE EXAMPLES --\u003e\n## Usage\n\nCreate the `MVTSource` object and then insert it as a `overlayMapType`. \nProvide the vector tiles server url in the options object.\n\n\n```js\nvar options = {\n    url: \"http://your_vector_tiles_url/{z}/{x}/{y}.pbf\"\n};\n\nvar mvtSource = new MVTSource(map, options);\nmap.overlayMapTypes.insertAt(0, mvtSource);\n```\n\n### Recommendations\n\n* Insert the `MVTSource` after tiles have been loaded for the first time \nto avoid duplicate invocation to `GetTile()`. It is documented in [this issue tracker](https://issuetracker.google.com/issues/73335429).\n\n```js\n google.maps.event.addListenerOnce(map, 'tilesloaded', function () {\n    map.overlayMapTypes.insertAt(0, mvtSource);\n});\n```\n\n* If you need to set style based on feature property or trigger `onClick` or `onMouseHover` event, \nset the property `getIDForLayerFeature` option with the function that returns the unique id for each feature.\n\n```js\nvar options = {    \n    getIDForLayerFeature: function(feature) {\n        return feature.properties.id;\n    }\n};\n```\n\n* Enable cache for better performance and smooth flow.\n```js\nvar options = {    \n    cache: true\n};\n```\n\n* Set the `sourceMaxZoom` option to enable [overzoom](https://docs.mapbox.com/help/glossary/overzoom/).\n```js\nvar options = {    \n    sourceMaxZoom: 14\n};\n```\n\n\n\u003c!-- DOCUMENTATION --\u003e\n## Documentation\n\nSee [documentation](https://github.com/techjb/Vector-Tiles-Google-Maps/blob/master/DOCUMENTATION.md) for the contructor options and public methods.\n\n\u003c!-- ROADMAP --\u003e\n## Roadmap\n\nSee the [open issues](https://github.com/techjb/Vector-Tiles-Google-Maps/issues) for a list of proposed features (and known issues).\n\n\n\u003c!-- CONTRIBUTING --\u003e\n## Contributing\n\nContributions are what make the open source community such an amazing place to be learn, inspire, and create.
