High-performance Node.js image processing powered by libvips, built for fast resizing and format conversion.
concurrently
Run multiple terminal commands in parallel, with color-coded output and cross-platform support.
Tokio
The async runtime powering most of Rust's networked, concurrent, and I/O-bound applications.
futures
The foundational Future, Stream, and Sink traits and combinators for zero-cost async Rust
Pillow
The friendly PIL fork that adds image processing capabilities to Python
RxJS
The standard library for composing asynchronous and event-based programs using observable sequences
qrcode
A zero-dependency-on-canvas QR code and 2D barcode generator for Node.js and the browser.
PDF.js
Mozilla's HTML5-based library for parsing and rendering PDF documents in the browser and Node.js.
p-limit
A tiny, battle-tested utility for running async functions with a strict concurrency limit.
file-type
Detect the file type of a buffer, stream, or file by reading its magic number.
async-trait
Type erasure for async fn in Rust traits, enabling async methods behind dyn dispatch.
html-to-image
Turns any DOM node into a PNG, JPEG, SVG, or canvas image entirely client-side, with no server or screenshot service required.
Gunicorn
A fast, lightweight pre-fork WSGI and ASGI HTTP server for running Python web apps in production on UNIX.
websockets
Build correct, fast WebSocket servers and clients in Python with asyncio, threading, or Sans-I/O APIs.
qrcode.react
A React component for generating QR codes as SVG or Canvas, with logo embedding and full styling control.
async-mutex
Mutex and semaphore primitives for synchronizing async workflows in JavaScript and TypeScript.
once_cell
Single-assignment cells and lazy statics for Rust, without macros or unsafe code
tokio-tungstenite
Asynchronous, Tokio-native WebSocket streams built on tungstenite
html2canvas
Render live DOM into canvas screenshots entirely in the browser, no server required
async
Higher-order async utility functions for callback, async/await, and promise-based control flow in Node.js and the browser.
svgo
A Node.js library and command-line tool that optimizes SVG files by removing redundant markup through a configurable plugin pipeline.
Tower
Modular, reusable Rust components for building async network clients and servers
pdf-parse
Pure TypeScript PDF parser for extracting text, images, tables, and metadata in Node.js and browsers.
rayon
Simple, guaranteed data-race-free work-stealing parallelism for Rust — turn sequential iterators parallel by changing one call.
