## What it is
Keyv is a TypeScript key-value storage library providing a consistent interface across multiple backends via storage adapters (Redis, Postgres, MySQL, SQLite, MongoDB, Memcache, etcd, DynamoDB, Cloudflare KV, and in-memory). It supports TTL-based expiry, compression, serialization, and namespaces, making it suitable as a cache or persistent key-value store.

## Use cases
- add caching to a node.js app with redis or sqlite backend
- swap key-value storage backends without changing code
- store session data with ttl expiry
- cache api responses in express or fastify
- persist key-value data in cloudflare workers
- add cache support to my own npm module

## When to choose
- you need a unified key-value API across many storage backends
- you want TTL-based caching in Node.js or the browser
- you want to make your library's storage backend pluggable

## When to avoid
- you need complex queries, joins, or relational data
- you need a distributed cache with built-in eviction policies like a dedicated Redis deployment
- you are not in the JavaScript/TypeScript ecosystem

## Facets
- artifact type: library
- maturity: active
- function: caching, database, serialization, compression
- domain: databases, web-development, backend, developer-tools
- platform: bun, browser, cross-platform
- tags: key-value-store, storage-adapters, ttl, cache, redis, sqlite, monorepo, nodejs, typescript
