“caching”
Dependency Caching for npm, pip, Go Modules, and Cargo
Two layers of build caching for language dependencies: lockfile-first COPY ordering plus BuildKit cache mounts, with Dockerfiles for npm, pip, Go, and Cargo.
Caching for Agentic RAG: Index Refresh and Query Caching
Agentic RAG loops re-retrieve constantly. Layer query caching, response caching, and index refresh policies to cut latency and LLM bills without serving stale answers.
GraphQL in Flutter: Queries, Caching, and Subscriptions with graphql_flutter
A practical guide to GraphQL in Flutter with graphql_flutter: client setup with links and caching, Query and Mutation widgets, optimistic updates, WebSocket subscriptions, hooks, and code generation.
Caching Tool Results to Shorten Agent Trajectories
Agent trajectories grow expensive fast because every tool call costs a model round trip. Learn what is safely cacheable, how to key the cache, where to place it in a LangGraph graph, and how to measure the wins.
Flutter Image Loading and Caching: From Image.network to CachedNetworkImage
How Flutter caches images in memory, how FadeInImage and precacheImage smooth the loading experience, and when to reach for disk caching with cached_network_image.
Speeding Up Generative UI with Async A2UI Caching
LLM startup latency kills generative UI. Learn how to pre-generate A2UI messages on the backend, cache them, and render instant GenUI in Flutter on app launch.
Web Performance: Caching Strategies and CDNs
Practical caching strategies and CDN setup for web apps — HTTP cache headers, cache invalidation, service workers, and CDN configuration for global delivery.
Offline-First PWA Patterns That Users Love
Cache-first, network-first, stale-while-revalidate — the service worker strategies that make PWAs work without a network, plus app shell, background sync, and offline UX.
Semantic Caching to Reduce Latency and Spend
Users ask the same question a hundred different ways. Semantic caching serves cached answers for similar queries — cutting LLM spend by up to 86% and latency from seconds to milliseconds.
Prompt Caching Strategies to Cut LLM API Costs
Cached input tokens are ~90% cheaper than fresh ones. Learn implicit vs explicit caching, TTL design, and how to structure prompts so your cache hits.
Optimizing Agent Performance: Context Caching with Gemini in the Google ADK
Learn how to leverage context caching in the Google Agent Development Kit (ADK) with Gemini 2.0+ models to significantly reduce latency and costs for token-heavy agent interactions.
