This package provides a way for building command-line interfaces in Node.js.

A cache object that deletes the least-recently-used items. Specify a max number of the most recently used items that you want to keep, and this cache will keep that many of the most recently accessed items.

The debug module exposes a function, which if called with a module name as argument provides a function that writes debug output to console.error under that module name. This output can be controlled in a more fine-grained manner by binding the DEBUG variable.

Color-convert is a color conversion library for JavaScript and node. It converts all ways between rgb, hsl, hsv, hwb, cmyk, ansi, ansi16, hex strings, and CSS keywords (will round to closest)

This package provides a way to match balanced string pairs.

Typescript definition (d.ts) files for Undici.

This module contains header-only C++ wrapper classes which simplify the use of the C based Node-API provided by Node.js when using C++. It provides a C++ object model and exception handling semantics with low overhead.

Node-API is an ABI stable C interface provided by Node.js for building native addons. It is intended to insulate native addons from changes in the underlying JavaScript engine and allow modules compiled for one version to run on later versions of Node.js without recompilation. The node-addon-api module, which is not part of Node.js, preserves the benefits of the Node-API as it consists only of inline code that depends only on the stable API provided by Node-API.

It is important to remember that other Node.js interfaces such as libuv (included in a project via #include <uv.h>) are not ABI-stable across Node.js major versions.

This package provides an async helper for Node.js that manages pending callbacks and signals completion when all have finished.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

Parsers are used to take raw binary data and transform them into usable messages. This package provides ByteLength, a parser that emits data as a buffer every time a specified number of bytes are received.

Extremely high performant utility for building tools that read the file system, minimizing filesystem and path string munging operations to the greatest degree possible..

Validate XML, Parse XML to JS Object, or Build XML from JS Object without C/C++ based libraries and no callback. * Validate XML data syntactically. Use detailed-xml-validator to verify business rules. * Parse XML to JS Objectand vice versa * Common JS, ESM, and browser compatible * Faster than any other pure JS implementation. It can handle big files (tested up to 100mb). XML Entities, HTML entities, and DOCTYPE entites are supported. Unpaired tags (Eg <br> in HTML), stop nodes (Eg <script> in HTML) are supported. It can also preserve Order of tags in JS object

Native Abstractions for Node.js (``NaN'') provides a header file filled with macros and utilities for making add-on development for Node.js easier across versions. The goal is to provide all logic necessary to develop native Node.js addons without having to inspect NODE_MODULE_VERSION.

Library which allows deeply merging two different objects.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

Parsers are used to take raw binary data and transform them into usable messages. This package provides InterByteTimeout, a parser that emits data if there is a pause between packets for the specified amount of time.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

Parsers are used to take raw binary data and transform them into usable messages. This package provides Delimiter, a parser that emits data each time a specified byte sequence is received.

This package provides a user-land implementation of Node-core's string_decoder, which serves to decode buffers to strings so that the decoded string does not contain incomplete multibyte sequences.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

This package provides the Binding class, which uses a native addon to talk to the underlying system. You never have to use Binding objects directly. There is also a MockBinding available (but not yet packaged for Guix) to assist with testing.

This package provides a simple PNG encoder/decoder for Node.js with no dependencies.

This package provides a pure JavaScript JPEG encoder and decoder for Node.js.

once is a Node.js module to call a function exactly one time. Subsequent calls will either return the cached previous value or throw an error if desired.

This package provides a CRC32 algorithm that works with binary data and fancy character sets, signed or unsigned data and has tests, for Node.

Isomorphic, functional type-checking for Javascript.

Node SerialPort is a modular suite of Node.js packages for accessing serial ports. The Guix package node-serialport provides the recommended high-level interface.

Parsers are used to take raw binary data and transform them into usable messages. This package provides CCTalk, which emits packets for the ccTalk protocol (an open standard for currency detectors) as they are received.

Acornjs is a Javascript parser with many options and an architecture supporting plugins.
