Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

opcroak

An OPC-UA swiss-knife command-line tool.

Green application CodeFactor

Current version: 1.0.5

Lead Maintainer: Halim Qarroum

Table of contents

Install

npm install --global opcroak

Features

  • Ability to create an Expressify server agent able to connect, browse, query and subscribe OPC-UA server(s) over MQTT.
  • Recursive archiving of OPC-UA values using append-only output streams to dump notifications issued by variables.
  • Support of OPC-UA request(s) throttling and buffered write(s) to output stream(s).
  • Supports HTTP Proxy servers on the LAN to proxify MQTT connections.
  • Supports Windows, Linux and MacOS.

Description

This command-line application is a handy tool for developers or administrators wanting to perform the following actions on their OPC-UA server(s) :

  • Archive the data, in real-time, associated with the OPC-UA variables located in a given container. opcroak is able to recursively crawl the given container(s) and to monitor their associated variables. It can then push these data to Output streams.
  • Extract the list of variable node identifiers located into one or more container(s) located on one or many OPC-UA server(s). This list can then be used later on by a client application to subscribe to the referenced variables efficiently.
  • Provide an Expressify agent, connected to an MQTT server, allowing clients to interact with one or many OPC-UA server(s).

Usage

In this section, we are going to detail the different commands available by using opcroak as well as a guidance on how to use them with a configuration file.

Variable Archiving

This feature makes it possible to archive on an output stream the values associated with OPC-UA variables located in one or many OPC-UA containers on a remote OPC-UA server.
