v2.6.2 fixes one bug, and it's an important one: on a machine without husky installed globally, npm install @devilsdev/rag-pipeline-utils failed. That covers most laptops and every CI runner. Every release from 2.2.1 to 2.6.1 is affected. Please upgrade:

npm install @devilsdev/rag-pipeline-utils@latest

v2.6 makes the library easier to adopt alongside what you already run and cheaper to run in production. checkAnswer grounds answers from LangChain, LlamaIndex, Mastra or the Vercel AI SDK. A new /testing entry runs pipelines offline in tests, and opt-in caching skips the model calls for repeated questions. The CLI's query command can now show how it got its answer, and both the package and the CLI load several times faster. The current version is 2.6.2: 2.6.1 published the updated README to npm, and 2.6.2 fixes npm install on machines without husky (see the 2.6.2 post).

v2.5.0 is a consolidation release. The CLI now does real work end to end, every pipeline stage can be cancelled, grounding metrics measure what they claim to, and modules that were simulations are now clearly separated in an /experimental entry point. Several of these changes alter scores and defaults, so please read the upgrade notes before you update.

RAG Pipeline Utils v2.4.0 is the most significant release yet — transforming the project from a basic RAG toolkit into the most comprehensive Node.js RAG framework available. This release ships 104 public exports, up from 22 in v2.3.1.

Choosing the right RAG framework impacts development speed, performance, and maintainability. This comprehensive comparison helps you decide between LangChain and RAG Pipeline Utils based on your specific needs.

How we transformed a slow, costly RAG system into a high-performance production service by optimizing every layer of the stack. This case study shares specific techniques, measurements, and code that reduced P95 latency from 2000ms to 800ms.

Production RAG systems handle sensitive data and require comprehensive security measures. This post shares hard-earned lessons from securing RAG deployments at scale, covering authentication, input validation, data privacy, and threat mitigation.

Optimizing RAG pipeline performance requires understanding bottlenecks across embedding generation, vector search, and LLM inference. This guide provides proven techniques for achieving production-grade performance at scale.

Custom embedders allow you to tailor vector representations to your specific domain, improving retrieval accuracy and reducing dependency on external APIs. This deep dive explores the architecture, implementation patterns, and optimization techniques for building production-ready custom embedders.

RAG Pipeline Utils v2.2.0 Enterprise Edition delivers production-ready infrastructure with advanced AI capabilities, comprehensive observability, and enterprise-grade security features. This release establishes the platform as a complete solution for mission-critical RAG deployments.
