Work with the Upstash Redis JavaScript/TypeScript SDK for serverless Redis operations. Use for caching, session storage, rate limiting, leaderboards, full-text search (querying, filtering, aggregating with @upstash/redis search extension), and all Redis data structures. Supports automatic serialization/deserialization of JavaScript types. Search also available via @upstash/search-redis and @upstash/search-ioredis adapters for TCP clients.
The same skill content is published under more than one repo. The install counts are split across them; any of these commands works.
This directory contains comprehensive guides for using the @upstash/redis SDK. These skill files are designed to help developers and AI assistants understand and use the SDK effectively.
Set these in your .env file:
Redis data types with auto-serialization examples:
Complex operations and optimizations:
Common use cases and architectural patterns:
Optimization techniques and best practices:
Full-text search, filtering, and aggregation extension for Redis:
Migration guides from other libraries:
