Big-friendly JSON. Asynchronous streaming functions for large JSON data sets.
An async stream which can be iterated over using a for-await-of loop.
A readable async stream which can be iterated over using a for-await-of loop.
Node.js Streams, a user-land copy of the stream library from Node.js
Automated stream rotation useful for log files
Check if something is a Node.js stream
Get a stream as a string, Buffer, ArrayBuffer or array
tar-stream is a streaming tar parser and generator and nothing else. It operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system.
destroy a stream if possible
Toggle the CLI cursor
Call a callback when a readable/writable/duplex stream has completed or failed.
A shim for the setImmediate efficient script yielding API
Get and validate the raw body of a readable stream.
A streaming way to send data to a Node.js Worker Thread
Pure Javascript JSON to CSV converter.
A stream that emits multiple other streams one after another.
Streaming data for JavaScript
A tiny, zero-dependency yet spec-compliant asynchronous iterator polyfill/ponyfill for ReadableStreams.
Merge multiple streams into a unified stream
An iteration of the Node.js core streams with a series of improvements
Returns the next buffer/object in a stream's readable queue
Standalone Ruby SDK for AI generation across OpenRouter and Replicate, ElevenLabs speech-to-text, with iterative tool loops and SSE streaming.
sequel_pg overwrites the inner loop of the Sequel postgres adapter row fetching code with a C version. The C version is significantly faster than the pure ruby version that Sequel uses by default. sequel_pg also offers optimized versions of some dataset methods, as well as adds support for using PostgreSQL streaming.
Unified C-extension gem for zstd, lz4, and brotli compression. One-shot, streaming, IO wrappers, dictionary support. Fiber-friendly: cooperates with Fiber::Scheduler (async, falcon) so CPU-heavy compression never blocks the event loop. Ships vendored sources — no system libraries required.

RubyPi is a minimal, composable AI agent harness for Ruby. Build production-ready LLM agents and AI agents with a unified provider interface across OpenAI, Anthropic Claude, and Google Gemini, plus first-class support for tool calling (function calling), streaming responses, automatic retries, provider fallback, context compaction, and a think-act-observe agent loop. Anti-framework design — small, idiomatic, and explicit. Ideal for building autonomous AI agents, ReAct agents, tool-using LLM agents, and chatbots in Ruby.
Scrapetor is a Ruby HTML parsing + scraping toolkit. The parser is a native C arena DOM with structural indexes built at parse time and NEON SIMD scanners in the SAX hot loop. A streaming extraction engine compiles the schema DSL into a single forward pass — no DOM materialised, one Ruby boundary crossing per document. On builds where libcurl is available, Scrapetor::Fetcher adds an HTTP/2-capable fetch layer with per-thread connection cache, shared DNS + TLS session pool, in-process gzip / deflate / brotli / zstd decoding, iconv charset transcoding, retry + exponential backoff, ETag / Last-Modified disk cache with bulk revalidation, per-host throttle, cookie jar, basic + bearer auth, proxy, and three bulk concurrency models (parallel_fetch / multi_fetch / streaming multi_each). Scrapetor::Session ties the cookie / auth / throttle / retry policies together. Also ships robots.txt + sitemap.xml parsers, a bounded-memory streaming HTML parser, and structured-data extractors (JSON-LD, OpenGraph, Schema.org, Microdata, RDFa, Twitter Cards). The Net::HTTP-based Scrapetor.fetch is preserved as the no-libcurl fallback.
