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

js-aprs-fap npm Build Status Coverage Status

APRS is a registered trademark Bob Bruninga, WB4APR.

This is an APRS parser based on Ham::APRS::FAP rewritten in JavaScript. Therefore, much of what is listed here is directly copied from the original repository.

Goals - work in progress

  • Be lightweight
  • Parse all message types
  • Full code coverage with unit tests

Implemented features - parse

  • normal
  • mic-e and compressed location packets
  • NMEA location packets
  • objects
  • items
  • messages
  • telemetry
  • weather packets

Needs test cases to implement

  • DX
  • Capabilities

Additional Information

As of right now, this module's goal of functionality and behavior is to be similar to the original library. However, upon complete conversion, the code base and functionality will probably begin to diverge to better meet the JavaScript paradigm. Also optimizations will be made to try to imporove performance.

APRS features specifically NOT handled by this module:

  • special objects (area, signpost, etc)
  • network tunneling/third party packets
  • direction finding
  • station capability queries
  • status reports (partially)
  • user defined data formats

Optimizations Needed

  • Quit leaking arguments (modifying them), explicitly return the $rethash value. Any errors thrown, should also be done explicitly.

Unit Tests Needed

  • packet that causes a result code: srccall_noax25

May have issues

  • _wx_parse
    • comments/software - trimming may not be accurate
  • Uncompressed positions
    • Do lat/long need to be trimmed to 4 decimal places?

USAGE
