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 🙏

Readme

Reach Protocol Web Client

This library is designed to facilitate communication with devices that implement the Reach Protocol, using a user-defined transport method (e.g. BLE). Currently-supported services are:

  • Parameter Repository (discover, read, write, notify)
  • Commands (discover, send)
  • Command-Line Interface (send, receive)
  • Files (discover, download, upload)
  • Time (read, write)
  • WiFi (discover, connect, disconnect)

Usage

Communication with a Reach-enabled device is achieved by creating a new DeviceAccess object, which provides methods for accessing state, reacting to events, and sending commands to the device. When creating a DeviceAccess object, a transport method must be provided that extends the NetworkAccess abstract class with implementations of the constructor and sendBytes method, along with calling the received method when bytes are received.

Changelog

  • 1.4.3
    • Bugfix to handling of headers with reported size over 255 bytes.
  • 1.4.2
    • Removed outdated "read after timestamp" configuration from readParameters.
    • Removed abstract connect method from NetworkAccess due to lack of utility in varied implementation contexts.
    • Removed connect method from DeviceAccess for above-stated reason.
    • Added optional configuration to pingString method for consistency.
    • Improved TSDoc documentation of DeviceAccess and NetworkAccess.
  • 1.4.1
    • Bugfix to WiFi service
    • Bugfix to classic header selection
  • 1.4.0
    • Implemented request state handling for file transfers, including substantial changes to the FileTransfer class.
    • Updated to Reach Protocol 0.2.3.
    • Transitioned to new header format, with use of "classic" headers configurable in DeviceAccess.
  • 1.3.1
    • Implemented request state handling for all categories except file transfers, including error responses. Core async functions now return upon a complete set of successful responses from the server, rather than upon the initial request being sent.
