Small, focused packages for Node.js. Each one does one thing well. Many are distributed, backed by Redis or Postgres with leader election, clustering, and shared state built in. All ESM, zero or minimal dependencies, published under the @prsm scope on npm.

Package	Test	Version	Description
@prsm/ms			Parse and convert time strings to milliseconds
@prsm/ids			Short, obfuscated, collision-proof, reversible identifiers
@prsm/hash			Simple salted string hashing on top of node:crypto
@prsm/from			Fluent query builder for filtering, transforming, and aggregating arrays of objects
@prsm/fsm			Non-deterministic finite state machine with time-based ticks, persistence, and multiple active states
@prsm/lock			Distributed locking primitives for Redis - mutex and semaphore
@prsm/limit			Redis-backed distributed rate limiting with token bucket, sliding window, and leaky bucket algorithms
@prsm/cache			Distributed cache with stampede prevention, stale-while-revalidate, and tag invalidation
@prsm/trace			Distributed trace propagation with W3C TraceContext, AsyncLocalStorage, and framework adapters
@prsm/cron			Redis-backed distributed cron scheduler with leader election and cron expression support
@prsm/queue			Redis-backed distributed task queue with grouped concurrency, retries, and rate limiting
@prsm/cells			Reactive computation graph with distributed coordination via Redis
@prsm/workflow			Durable, inspectable workflow engine
@prsm/meter			Durable usage metering for billing and quotas, backed by postgres
@prsm/entitle			Plan-based entitlements and feature gating, resolved at runtime, backed by postgres
@prsm/auth			PostgreSQL-backed Express authentication: sessions, OAuth, roles, two-factor, and audited impersonation
@prsm/realtime			Distributed WebSocket framework with Redis-backed rooms, records, presence, channels, collections, and persistence
@prsm/log			Structured logging with child contexts
@prsm/devtools			Read-only Express middleware dashboard for observing @prsm infrastructure at runtime
@prsm/ai			Composable LLM inference with multi-provider support, tool execution, streaming, structured output, and approval workflows
@prsm/embed			Text embeddings with multi-provider support, batching, and cosine similarity
@prsm/imagegen			Image generation across OpenAI, xAI, and Google with normalized options and raw provider passthrough

This ecosystem is an experiment in AI-maintained open source. All packages are autonomously built, tested, and refined by AI with human oversight. Regular audits, thorough test coverage, continuous refinement - the emphasis is on high quality, rigorously tested, production-grade code.
