Production-ready integration patterns for Mapbox GL JS across React, Vue, Svelte, Angular, and vanilla JavaScript. \n \n Covers framework-specific lifecycle management (useEffect/useRef in React, mounted/unmounted in Vue, onMount/onDestroy in Svelte, ngOnInit/ngOnDestroy in Angular) with proper cleanup to prevent memory leaks \n Includes Web Components pattern for framework-agnostic reusable map elements and cross-framework compatibility \n Provides token management via environment variables, Se

Visual snapshot testing for web renderer components using vitest fixtures. \n \n Create test fixtures in packages/web-renderer/src/test/fixtures that define a React component, dimensions, frame rate, and duration \n Register fixtures in packages/web-renderer/src/test/Root.tsx to enable preview functionality \n Write test cases that render stills using renderStillOnWeb() and validate output with testImage() snapshot comparison \n Run tests with bunx vitest src/test/video.test.tsx and update docum

CloudBase document database Web SDK for querying, creating, updating, and deleting data in web applications. \n \n Supports CRUD operations, complex queries with operators (gt, gte, lt, lte, eq, neq, in, nin), and method chaining for filtering, sorting, and field selection \n Includes pagination via skip/limit, aggregation pipelines, geolocation queries, and real-time data synchronization with watch() listeners \n Requires SDK initialization with environment ID and authentication before database

Web service architecture with async handlers, type-safe extractors, and middleware composition. \n \n Enforces async-first design to prevent blocking request handlers; use spawn_blocking for CPU-intensive work \n Manages shared application state via Arc<T> and Arc<RwLock<T>> to ensure thread safety across concurrent requests \n Provides extractor pattern for request parsing and validation (e.g., State(db) , Json(payload) ) with unified error responses via IntoResponse \n Supports

Performance optimization patterns for Mapbox GL JS applications, prioritized by user impact. \n \n Eliminate initialization waterfalls by loading map data in parallel with map initialization, and set precise viewport to avoid redundant tile fetches \n Use symbol layers for 100+ markers (GPU-accelerated) and clustering for 10,000+ features; avoid HTML markers at scale \n Choose GeoJSON for datasets under 5 MB, vector tiles for 20+ MB; implement viewport-based loading to reduce bandwidth \n Always

AI text generation and streaming for browser applications via CloudBase SDK. \n \n Supports two providers: Hunyuan (recommended: hunyuan-2.0-instruct-20251111 ) and DeepSeek (recommended: deepseek-v3.2 ) \n Two core methods: generateText() for non-streaming responses and streamText() for incremental text chunks with async iteration \n Requires @cloudbase/js-sdk initialization with anonymous authentication and publishable API key from CloudBase console \n Not suitable for Node.js backends, WeChat

Web frontend authentication with multiple login methods and complete user management for CloudBase. \n \n Supports 8 login methods: phone/email OTP, password, anonymous, OAuth (Google/WeChat), custom ticket, and anonymous account upgrade \n Includes full user management: sign out, profile updates, password changes, identity linking/unlinking, and account deletion \n Built-in auth state listeners and session management with access token retrieval for API calls \n Compatible with @cloudbase/js-sdk

Expert guidance for building scalable web scrapers and crawlers using Scrapy with best practices for spider development, data extraction, and pipeline management. \n \n Covers spider architecture, CSS/XPath data extraction, Item Pipelines, and middleware development for request/response handling \n Includes strategies for rate limiting, User-Agent rotation, proxy management, and handling JavaScript-rendered content with Scrapy-Splash or Scrapy-Playwright \n Provides error handling patterns, perf
