aprs-view-js

APRS is a registered trademark Bob Bruninga, WB4APR.

This is intended to be a fairly lightweight, cross platform, graphical APRS client. Currently, this is a read-only client. The only ability it has to send data is a login packet to the server. There are certain packets that cannot be handled by the client, which is a limitation of the js-aprs-fap library.

aprs-view-js is NOT intended to be run as a web server and would cause many issues and potential system vulnerabilities being run as such. There are plenty of amazing online APRS clients such as https://aprs.fi.

Features

• Ability to connect to either an aprsc or Jav-APRS-IS server.
• See raw data packets in output window.

  • BUGS/ENHANCEMENTS (B/E):
    • B - Clearing all markers currently doesn't work properly. Working with kefir/bacon may help mitigate this
    • B - Items/Objects may have multiple locations with the same callsign
    • E - Items/Objects may have multiple locations with the same value, this will result in only 1 showing up
    • E - Weather packets with no locations - if we know the location of the station already, update the id to get the latest when the icon is clicked?
    • B - Overlays are not allowing newer markers to cover them
    • E- APRSViewJS used Bacon/Kefir for filtering and packet types, can these be easily utilized to make packets easier to handle source/Vector.js
      • Is it possible to rewrite/extend VectorSource in openlayers to accept an observable array of features? https://github.com/openlayers/openlayers/blob/main/src/ol/
      • This could lead down a rabbit hole where the entire lib needs to be rewritten
      • Collection would likely need to be rewritten - https://github.com/openlayers/openlayers/blob/b7ccb68b02bd936373b1bd1d2f5ca445e1d286e0/src/ol/Collection.js
