+# ol-source-tile-debug
+
+A pseudo tile source, which does not fetch tiles from a server, but renders a grid outline for the tile grid/projection along with the coordinates for each tile.
+See examples/canvas-tiles for an example.
+
+<script setup>
+import TileDebugDemo from "@demos/TileDebugDemo.vue"
+import ProjectionRegisterDemo from "@demos/ProjectionRegisterDemo.vue"
+</script>
+
+<ClientOnly>
+<ProjectionRegisterDemo />
+<hr />
+<TileDebugDemo />
+</ClientOnly>

+## Usage
+
+::: code-group
+
+<<< ../../../../src/demos/TileDebugDemo.vue
+
+:::
+
+## Properties
+
+### Props from OpenLayers
+
+Properties are passed-trough from OpenLayers directly.
+Their types and default values can be checked-out [in the official OpenLayers docs](https://openlayers.org/en/latest/apidoc/module-ol_source_TileDebug-TileDebug.html).
+Only some properties deviate caused by reserved keywords from Vue / HTML.
+This deviating props are described in the section below.
+
+### Deviating Properties
+
+None.
+
+## Events
+
+You have access to all Events from the underlying source.
+Check out [the official OpenLayers docs](https://openlayers.org/en/latest/apidoc/module-ol_source_TileDebug-TileDebug.html) to see the available events tht will be fired.
+
+```html
+<ol-source-tile-debug @error="handleEvent" />
+```
+
+## Methods
+
+You have access to all Methods from the underlying source.
+Check out [the official OpenLayers docs](https://openlayers.org/en/latest/apidoc/module-ol_source_TileDebug-TileDebug.html) to see the available methods.
+
+To access the source, you can use a `ref()` as shown below:
+
+```vue
+<template>
+  <!-- ... -->
+  <ol-source-tile-debug ref="sourceRef" />
+  <!-- ... -->
+</template>
+
+<script setup lang="ts">
+import { ref, onMounted } from "vue";
+import type TileDebug from "ol/source/TileDebug";
+
+const sourceRef = ref<{ source: TileDebug }>(null);
+
+onMounted(() => {
+  const source: TileDebug = sourceRef.value?.source;
+  // call your method on `source`
+});
+</script>
+```
