serial-port-json-server - A serial port JSON websocket server for Windows, Mac, Linux, Raspberry Pi, or BeagleBone Black that lets you communicate with your serial port from a web application

  •    Go

A serial port JSON websocket & web server that runs from the command line on Windows, Mac, Linux, Raspberry Pi, or Beagle Bone that lets you communicate with your serial port from a web application. This enables web apps to be written that can communicate with your local serial device such as an Arduino, CNC controller, or any device that communicates over the serial port. Since version 1.82 you can now also program your Arduino by uploading a hex file. The app is written in Go. It has an embedded web server and websocket server. The server runs on the standard port of localhost:8989. You can connect to it locally with your browser to interact by visiting http://localhost:8989. The websocket is technically running at ws://localhost/ws. You can of course connect to your websocket from any other computer to bind in remotely. For example, just connect to ws:// if you are on a remote host where is your devices actual IP address.

Serial Port Terminal (SPTerm)


Serial Port Terminal (SPTerm) is used for basic communication using serial port (com). Sending bytes and ASCII from PC can be done using SPTerm. It is useful for micro controller projects for UART and simple transmission. Hex data can be sent out directly from text box in SPTerm

acme - :lock: acmetool, an automatic certificate acquisition tool for ACME (Let's Encrypt)

  •    Go

acmetool is an easy-to-use command line tool for automatically acquiring certificates from ACME servers (such as Let's Encrypt). Designed to flexibly integrate into your webserver setup to enable automatic verification. Unlike the official Let's Encrypt client, this doesn't modify your web server configuration.You can perform verifications using port 80 or 443 (if you don't yet have a server running on one of them); via webroot; by configuring your webserver to proxy requests for /.well-known/acme-challenge/ to a special port (402) which acmetool can listen on; or by configuring your webserver not to listen on port 80, and instead running acmetool's built in HTTPS redirector (and challenge responder) on port 80. This is useful if all you want to do with port 80 is redirect people to port 443.

sql.js - SQLite compiled to JavaScript through Emscripten

  •    Javascript

sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a javascript typed array. There is no C bindings or node-gyp compilation here, sql.js is a simple javascript file, that can be used like any traditional javascript library. If you are building a native application in javascript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to javascript.

ghostunnel - A simple SSL/TLS proxy with mutual authentication for securing non-TLS services

  •    Go

Ghostunnel is a simple TLS proxy with mutual authentication support for securing non-TLS backend applications.Ghostunnel supports two modes, client mode and server mode. Ghostunnel in server mode runs in front of a backend server and accepts TLS-secured connections, which are then proxied to the (insecure) backend. A backend can be a TCP domain/port or a UNIX domain socket. Ghostunnel in client mode accepts (insecure) connections through a TCP or UNIX domain socket and proxies them to a TLS-secured service. In other words, ghostunnel is a replacement for stunnel.

Null-modem emulator

  •    C

The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

seaport - semver service registry for clusters

  •    Javascript

Seaport stores (host,port) combos (and other metadata) for you so you won't need to spend so much effort keeping configuration files current as your architecture grows to span many processes on many machines. Just register your services with seaport and then query seaport to see where your services are running.In this example we'll register a service with seaport and then elsewhere connect to it.

Coolstorage - ORM library for .NET

VFSForGit - Virtual File System for Git: Enable Git at Enterprise Scale

  •    CSharp

VFS stands for Virtual File System. VFS for Git virtualizes the file system beneath your git repo so that git and all tools see what appears to be a normal repo, but VFS for Git only downloads objects as they are needed. VFS for Git also manages the files that git will consider, to ensure that git operations like status, checkout, etc., can be as quick as possible because they will only consider the files that the user has accessed, not all files in the repo. This project was formerly known as GVFS (Git Virtual File System). It is undergoing a rename to VFS for Git. While the rename is in progress, the code, protocol, built executables, and releases may still refer to the old GVFS name. See for the latest status of the rename effort.

primus - :zap: Primus, the creator god of the transformers & an abstraction layer for real-time to prevent module lock-in

  •    Javascript

Primus, the creator god of transformers but now also known as universal wrapper for real-time frameworks. There are a lot of real-time frameworks available for Node.js and they all have different opinions on how real-time should be done. Primus provides a common low level interface to communicate in real-time using various real-time frameworks.If you deploy your application behind a reverse proxy (Nginx, HAProxy, etc.) you might need to add WebSocket specific settings to its configuration files. If you intend to use WebSockets, please ensure that these settings have been added. There are some example configuration files available in the observing/balancerbattle repository.

pem - Create private keys and certificates with node.js

  •    Javascript

Here are some examples for creating an SSL key/cert on the fly, and running an HTTPS server on port 443. 443 is the standard HTTPS port, but requires root permissions on most systems. To get around this, you could use a higher port number, like 4300, and use https://localhost:4300 to access your server. Please have a look into the API documentation.
