node-topojson is an extension of GeoJSON that encodes topology. Rather than representing geometries discretely, geometries in TopoJSON files are stitched together from shared line segments called *arcs*. TopoJSON eliminates redundancy, offering much more compact representations of geometry than with GeoJSON; typical TopoJSON files are 80% smaller than their GeoJSON equivalents. In addition, TopoJSON facilitates applications that use topology.

This library provides a means to interface with the OpenTherm Gateway over serial or network connections. It enables communication with boilers and thermostats for executing and receiving commands and status updates. Functions include setting control setpoints, managing hot water override options, and configuring GPIO pins. Through this library, one can obtain comprehensive status information from the connected devices, selecting specific data points like temperatures, pressure, and operational statuses. The library supports both reading and writing operations to control connected heating systems effectively.

Kokyu is a library designed to provide flexible scheduling and dispatching services.

This package provides interfaces for XML parsing based on Simple API for XML (SAX) 2.0, defined by David Megginson. This is an event-driven parsing approach.

The evaluation of a mathematical expression is a standard task required in many applications. It can be solved by either using a standard math expression parser such as muparser or by embedding a scripting language such as Lua. There are however some limitations: Although muparser is pretty fast it will only work with scalar values and although Lua is very flexible it does neither support binary operators for arrays nor complex numbers. So if you need a math expression parser with support for arrays, matrices and strings muparserx may be able to help you. It was originally based on the original muparser engine but has since evolved into a standalone project with a completely new parsing engine.

LuaSQLite 3 is a thin wrapper around the public domain SQLite3 database engine. The lsqlite3 module supports the creation and manipulation of SQLite3 databases. Most sqlite3 functions are called via an object-oriented interface to either database or SQL statement objects.
