Use when fetching remote data, managing HTTP requests, working with colors, handling events, debugging errors, or using utility functions like defined, clone, or buildModuleUrl.\"\n---\n# CesiumJS Core Utilities & Networking\n\nVersion baseline: CesiumJS v1.143+ (ES module imports, `defaultValue` removed in v1.134)\n\n## Breaking Change: defaultValue Removed (v1.134)\n\n```js\n// WRONG (removed in v1.134)\nconst name = defaultValue(options.name, \"default\");\nconst opts = defaultValue(options, defaultValue.EMPTY_OBJECT);\n\n// CORRECT (v1.134+)\nimport { Frozen } from \"cesium\";\nconst name = options.name ?? \"default\";\nconst opts = options ?? Frozen.EMPTY_OBJECT;\n```\n\n`Frozen.EMPTY_OBJECT` is `Object.freeze({})` and `Frozen.EMPTY_ARRAY` is `Object.freeze([])`. Use them as safe defaults for options objects and array parameters.\n\n## Resource: HTTP Requests and Data Fetching\n\n`Resource` is the unified class for all HTTP operations. It wraps URL construction, query parameters, headers, proxying, and retry logic.\n\n### Fetching Data\n\n```js\nimport { Resource } from \"cesium\";\n\n// Static shorthand: accepts a URL string or options object\nconst jsonData = await Resource.fetchJson({ url: \"https://api.example.com/data.json\" });\n\n// Instance-based: construct once, reuse for multiple fetches\nconst resource = new Resource({\n url: \"https://api.example.com/features\",\n queryParameters: { format: \"json\", limit: \"100\" },\n headers: { \"Authorization\": \"Bearer my-token\" },\n});\nconst features = await resource.fetchJson();\nconst text = await resource.fetchText(); // string\nconst buffer = await resource.fetchArrayBuffer(); // ArrayBuffer\nconst blob = await resource.fetchBlob(); // Blob\nconst image = await resource.fetchImage(); // HTMLImageElement or ImageBitmap\n```\n\n### Derived Resources and Template Values\n\n```js\nimport { Resource } from \"cesium\";\n\nconst api = new Resource({\n url: \"https://tiles.example.com/{version}/tiles/{z}/{x}/{y}.png\",\n templateValues: { version: \"v2\" },\n headers: { \"X-Api-Key\": \"abc123\" },\n});\n\n// getDerivedResource inherits headers, proxy, and retry settings\nconst tile = api.getDerivedResource({\n templateValues: { z: \"10\", x: \"512\", y: \"384\" },\n});\nconst tileImage = await tile.fetchImage();\n\n// Modify query parameters on an existing resource\nresource.setQueryParameters({ access_token: \"new-token\" });\nresource.appendQueryParameters({ extra: \"param\" });\n```\n\n### Retry and Proxy\n\n```js\nimport { Resource, DefaultProxy } from \"cesium\";\n\n// Retry on specific HTTP status codes\nconst resource = new Resource({\n url: \"https://api.example.com/unstable\",\n retryAttempts: 3,\n retryCallback: (resource, error) => {\n if (error.statusCode === 429) {\n return new Promise((resolve) => setTimeout(() => resolve(true), 2000));\n }\n return false;\n },\n});\n\n// DefaultProxy appends the target URL as a query parameter\nconst proxied = new Resource({\n url: \"https://external-server.com/data.json\",\n proxy: new DefaultProxy(\"/proxy/\"),\n});\n// Request goes to: /proxy/?https%3A%2F%2Fexternal-server.com%2Fdata.json\n```\n\n### POST and PUT\n\n```js\nimport { Resource } from \"cesium\";\n\nconst resource = new Resource({ url: \"https://api.example.com/upload\" });\nconst result = await resource.post(JSON.stringify({ name: \"test\" }), {\n headers: { \"Content-Type\": \"application/json\" },\n});\n// resource.put() works the same way\n```\n\n## Color\n\nRGBA components as floats [0.0, 1.0]. Over 140 named constants as frozen static properties (e.g., `Color.RED`, `Color.CORNFLOWERBLUE`, `Color.TRANSPARENT`).\n\n### Creating Colors\n\n```js\nimport { Color } from \"cesium\";\n\nconst red = Color.RED; // frozen constant\nconst custom = new Color(0.2, 0.6, 0.8, 1.0); // float constructor\nconst blue = Color.fromCssColorString(\"#3498db\"); // hex string\nconst semiRed = Color.fromCssColorString(\"rgba(255,0,0,0.5)\"); // CSS rgba()\nconst coral = Color.fromBytes(255, 127, 80, 255); // 0-255 bytes\nconst hsl = Color.fromHsl(0.58, 0.8, 0.5, 1.0); // hue/sat/light\nconst bright = Color.fromRandom({ // constrained random\n minimumRed: 0.75, minimumGreen: 0.75, minimumBlue: 0.75, alpha: 1.0,\n});\n```\n\n### Manipulation and Conversion\n\n```js\nimport { Color } from \"cesium\";\n\nconst base = Color.fromCssColorString(\"#3498db\");\nconst translucent = base.withAlpha(0.5); // new Color with alpha\nconst lighter = base.brighten(0.3, new Color()); // requires result param\nconst darker = base.darken(0.3, new Color());\nconst css = base.toCssColorString(); // \"rgb(52,152,219)\"\nconst hex = base.toCssHexString(); // \"#3498db\"\nconst bytes = base.toBytes(); // [52, 152, 219, 255]\nconst equal = Color.RED.equals(new Color(1.0, 0.0, 0.0, 1.0)); // true\n```\n\n## Event System\n\n`Event` is the publish-subscribe mechanism used throughout CesiumJS. Classes expose Event properties like `Viewer.selectedEntityChanged` and `Cesium3DTileset.tileLoad`.\n\n### Basic Usage\n\n```js\nimport { Event } from \"cesium\";\n\nconst onDataReceived = new Event();\n\n// addEventListener returns a removal function\nconst removeListener = onDataReceived.addEventListener((data) => {\n console.log(\"Received:\", data);\n});\n\nonDataReceived.raiseEvent({ id: 1, value: \"test\" }); // invoke all listeners\nremoveListener(); // unsubscribe\n```\n\n### EventHelper for Batch Cleanup\n\n```js\nimport { EventHelper } from \"cesium\";\n\nconst helper = new EventHelper();\nhelper.add(viewer.selectedEntityChanged, (entity) => {\n console.log(\"Selected:\", entity?.name);\n});\nhelper.add(viewer.clock.onTick, (clock) => { /* per-frame logic */ });\nhelper.add(viewer.scene.globe.tileLoadProgressEvent, (queueLength) => {\n console.log(\"Tiles loading:\", queueLength);\n});\n\n// Remove all listeners at once (e.g., in a destroy method)\nhelper.removeAll();\n```\n\n## RequestScheduler Configuration\n\n`RequestScheduler` is a singleton that manages concurrent request limits. `Request` objects represent individual HTTP requests with priority and throttling (primarily internal).\n\n```js\nimport { RequestScheduler } from \"cesium\";\n\nRequestScheduler.maximumRequests = 64; // global max (default: 50)\nRequestScheduler.maximumRequestsPerServer = 12; // per-server max (default: 18)\n\n// Override for known HTTP/2 servers\nRequestScheduler.requestsByServer = {\n \"api.cesium.com:443\": 32,\n \"assets.cesium.com:443\": 32,\n};\n```\n\n## Error Handling\n\n- **DeveloperError** -- bug in calling code (invalid args). Thrown only in debug builds; fix the code, do not catch.\n- **RuntimeError** -- runtime failure (network, shader compile). Catch in production.\n\n```js\nimport { RuntimeError, formatError, Cesium3DTileset } from \"cesium\";\n\ntry {\n const tileset = await Cesium3DTileset.fromUrl(\"https://example.com/tileset.json\");\n viewer.scene.primitives.add(tileset);\n} catch (error) {\n if (error instanceof RuntimeError) {\n console.error(\"Failed to load tileset:\", error.message);\n } else {\n console.error(formatError(error)); // extracts name, message, stack\n }\n}\n```\n\n## Helper Functions\n\n### defined, clone, combine\n\n```js\nimport { defined, clone, combine } from \"cesium\";\n\n// defined: returns true if value is neither null nor undefined\nif (defined(entity.billboard)) {\n entity.billboard.scale = 2.0;\n}\n\n// clone: shallow by default, pass true for deep\nconst obj = clone({ a: 1, nested: { b: 2 } }, true);\n\n// combine: merge objects, first arg's keys take precedence\nconst merged = combine({ size: 20 }, { size: 10, color: \"red\" });\n// { size: 20, color: \"red\" }\n```\n\n### createGuid, buildModuleUrl\n\n```js\nimport { createGuid, buildModuleUrl } from \"cesium\";\n\nconst id = createGuid(); // \"xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx\"\n\n// Resolve paths relative to Cesium installation\nconst iconUrl = buildModuleUrl(\"Assets/Textures/maki/marker.png\");\n```\n\n### URL Utilities\n\n```js\nimport { objectToQuery, queryToObject, getExtensionFromUri, getBaseUri } from \"cesium\";\n\nconst qs = objectToQuery({ key1: \"value 1\", key2: [\"x\", \"y\"] });\n// \"key1=value%201&key2=x&key2=y\"\n\nconst parsed = queryToObject(\"key1=value%201&key2=x&key2=y\");\n// { key1: \"value 1\", key2: [\"x\", \"y\"] }\n\ngetExtensionFromUri(\"https://example.com/model.glb?v=2\"); // \"glb\"\ngetBaseUri(\"https://example.com/data/model.glb\"); // \"https://example.com/data/\"\n```\n\n### destroyObject\n\nReplaces all methods on an object with functions that throw `DeveloperError`, and sets `isDestroyed()` to return `true`. Standard cleanup pattern for objects holding native resources.\n\n```js\nimport { destroyObject } from \"cesium\";\n\nclass MyWidget {\n constructor(viewer) {\n this._handler = new Cesium.ScreenSpaceEventHandler(viewer.canvas);\n }\n isDestroyed() { return false; }\n destroy() {\n this._handler.destroy();\n return destroyObject(this);\n }\n}\n```\n\n## AssociativeArray\n\nO(1) key lookup with a live `values` array for allocation-free iteration in render loops.\n\n```js\nimport { AssociativeArray } from \"cesium\";\n\nconst items = new AssociativeArray();\nitems.set(\"building-1\", { height: 50 });\nitems.set(\"building-2\", { height: 80 });\n\nitems.get(\"building-1\"); // { height: 50 }\nitems.contains(\"building-1\"); // true\n\n// Iterate without per-frame allocations\nconst values = items.values;\nfor (let i = 0; i < values.length; i++) { /* process values[i] */ }\n\nitems.remove(\"building-1\");\nitems.removeAll();\n```\n\n## PinBuilder\n\nGenerates map pin canvas elements with colors, text, maki icons, or custom images.\n\n```js\nimport { PinBuilder, Color, Cartesian3, VerticalOrigin } from \"cesium\";\n\nconst pin = new PinBuilder();\nconst redPin = pin.fromColor(Color.RED, 48); // solid color\nconst textPin = pin.fromText(\"A\", Color.BLUE, 48); // text label\nconst iconPin = await pin.fromMakiIconId(\"hospital\", Color.GREEN, 48); // maki icon\nconst urlPin = await pin.fromUrl(\"/icons/custom.png\", Color.YELLOW, 48);\n\nviewer.entities.add({\n position: Cartesian3.fromDegrees(-75.17, 39.95),\n billboard: {\n image: pin.fromText(\"1\", Color.ROYALBLUE, 48),\n verticalOrigin: VerticalOrigin.BOTTOM,\n },\n});\n```\n\n## DistanceDisplayCondition\n\nControls entity/billboard/label visibility based on camera distance.\n\n```js\nimport { DistanceDisplayCondition, Cartesian3, Color } from \"cesium\";\n\nviewer.entities.add({\n position: Cartesian3.fromDegrees(-75.17, 39.95),\n billboard: {\n image: \"/icons/marker.png\",\n distanceDisplayCondition: new DistanceDisplayCondition(100.0, 50000.0),\n },\n});\n```\n\n## Feature Detection and Fullscreen\n\n```js\nimport { FeatureDetection, Fullscreen } from \"cesium\";\n\nif (FeatureDetection.supportsWebAssembly()) { /* WASM workers OK */ }\nif (FeatureDetection.supportsTypedArrays()) { /* TypedArrays OK */ }\n\nif (Fullscreen.supportsFullscreen()) {\n Fullscreen.requestFullscreen(viewer.container);\n}\n```\n\n## TaskProcessor\n\nWraps Web Workers for background computation. Worker is created lazily on first `scheduleTask`.\n\n```js\nimport { TaskProcessor, defined } from \"cesium\";\n\nconst processor = new TaskProcessor(\"myWorkerModule\");\nconst promise = processor.scheduleTask({ data: largeArray, op: \"simplify\" });\n\nif (!defined(promise)) {\n // Too many active tasks; retry next frame\n} else {\n const result = await promise;\n}\nprocessor.destroy(); // release worker when done\n```\n\n## TrustedServers\n\nCredentials (cookies, auth headers) are sent only to registered servers.\n\n```js\nimport { TrustedServers } from \"cesium\";\n\nTrustedServers.add(\"secure-tiles.example.com\", 443);\nTrustedServers.contains(\"https://secure-tiles.example.com/tileset.json\"); // true\nTrustedServers.remove(\"secure-tiles.example.com\", 443);\n```\n\n## Performance Tips\n\n1. **Reuse Resource instances** -- `getDerivedResource` inherits proxy, headers, and retry conf","tagline":"CesiumJS core utilities and networking - Resource, Color, Event, Request, RequestScheduler, error handling, helper functions, feature detection.
