Vehicle Tracking Client

This application consumes the Kafka events sent by the Vehicle Tracking application and offers the posibility to access them via an http API. A Javascript client perdiodically queries the API and displays the information using a chord diagram.

The Kafka consumer was written in Go using the kafka-go library.

The api web server was built with gorilla/mux router.

For the chord diagram the D3.js library was used.

Requirements

Usage

Download the repo:

$ git clone https://github.com/alxandru/client-vehicletracking.git
$ cd client-vehicletracking/

Build the project:

$ cd cmd/client-vehicletracking
$ go build

Run the application indicating the Kafka endpoint and the Kafka topic. They have to be the same as in Vehicle Tracking Application:

$ ./client-vehicletracking -kafkaendpoint=<Host:port> -topic=vehicletraffic

Once the consumer starts to read events from the vehicletraffic topic the application start to output what it reads:

Reading Message
Got message {"event":{"entry":"N", "exit":"SV-Exit", "id":11}}
Reading Message
Got message {"event":{"entry":"NV", "exit":"SE-Exit", "id":20}}
Reading Message
Got message {"event":{"entry":"SV", "exit":"N-Exit", "id":17}}
Reading Message
Got message {"event":{"entry":"N", "exit":"NE-Exit", "id":19}}
...
