Node.js itself is not single-threaded.
Node.js itself is not single-threaded.
Node.js developers often confuse the main single-threaded event loop with Node.js entirely.
When a Node.js app is running, it automatically creates 4 threads under the worker pool for blocking tasks.
So at any given time, there are at least five threads.
This worker pool is managed by Libuv.
The blocking tasks are mainly I/O-bound and CPU-intensive.
1. I/O bound
a. DNS: dns.lookup(), dns.lookupService()
b. File system except fs.FSWatcher()
2. CPU-int

Advanced RAG with guided generation
txtai is an all-in-one embeddings database for semantic search, LLM orchestration and language model workflows.
A standard RAG process typically runs a single vector search query and returns the closest matches. Those matches are then passed into a LLM prompt and used to limit the context and help ensure more factually correct answers are generated. This works well with most simple cases. More complex use cases, require a more advanced approach.
This article will demonstrate how constrained
