APRSWeb connects to Direwolf (or any AGWPE-compatible server, in
theory) and rendered received APRS frames onto a map in your web
browser. 
Unlike other APRS software, APRSWeb's target is to render into a web browser. You can think of APRSWeb as a self-hosted version of https://aprs.fi, except it can run on hardware as modest as a Raspberry Pi.
It uses Twirp to serialize those frames into JSON or protobuf objects, so it also doubles as an HTTP API for your APRS frames.
You'll need git, golang protoc-gen-twirp, and protoc per the
Twirp guide.
Once you have everything installed, run make.
This will output aprsweb as an ARMv6 Linux binary, and
aprsweb-native as whatever architecture/OS you're compiling on now.
Set up Direwolf with a radio or an rtl_fm device. This exercise is left to the reader, but certainly can be run on a raspi co-locating this service.
Run ./aprsweb-native -p port -s server substituting port and server
for the port and server of your AGWPE server.
If you set the environment variable DEBUG=1 aprsweb will log every
packet with base64
Note that we use git rev-parse HEAD --short upon build so APRSWeb
versions are exposed in HTTP headers.
An example Kubernetes deployment is included at aprsweb.yml for
those with letencrypt and nginx-ingress running.
I pipe the TNC test CD to Direwolf to play back synthetic packets, such as:
$ cat ~/direwolf.dummy
ADEVICE - null
CHANNEL 0
$ ffmpeg -i ~/TNC_Test_Ver-1.1.00.wav -f s16le -acodec pcm_s16le -ac 1 pipe: | direwolf -t 0 -r44100 -c ~/direwolf.dummy -
- Provide an easier way to customize:
- Map starting position
- Map zoom
- HTML template
- Provide a map provider picker for off-net usage
- Provide a filter for:
- Displaying a specific station's checkins only
- Automatically refresh the map every minute or so
Use specific icons for different station checkins(In progress)- Provide a way to swap out map API keys
- Integrate twirp / pb generation into Makefile better
- APRS test cd has some issues with Mic-E data, leading to screwed up lat/lng (specifically AC6VV-9)
- Write better docs :)
