YoGoGPS

Overview

A simple web server that serves up GPSD SKY and TPV data via SSE (ServerSideEvents).

Screenshot

Environment variables

• GPSD_SERVER - The IP and port of the gpsd process. (default: localhost:2947)

Commands

The simple compile and run in one:

$ go run yogogps.go

Or compile and then run the binary:

$ go build yogogps.go
$ ./yogogps.go

Note: go install won't work unless you then run it from the current project directory due to the required template and static files.

Usage

Once running, navigate the running host's URL on port 8555 (e.g. http://localhost:8555) to view the gps information.

Prometheus-style Metrics

The /metrics endpoint provide some basic prometheus style metrics:

• yogogps_gps_satellites_count - number of satellites currently received
• yogogps_gps_lat - currently computed latitude
• yogogps_gps_lon - currently computer longitude
• yogogps_num_clients - number of actively attached (SSE) clients viewing/using the server

Run Tests

To run the tests:

$ go test
