Driver Client prototype

The JavaScript version is the initial prototype of the driver client. Currently it can be used to visualize a vehicle's trip and to track stop requests. However it has no connection to the bus' hardware.

The more recent Python version can be found here: https://github.com/STOP2/stop2-rpi

The project consists of two parts:

• back folder - Docker-module for providing data to frontend
• front folder - frontend JavaScript prototype

front

Code is in the src folder:

• Main.js - Entrypoint
• NetworkHandler.js - Connection to the MQTT broker, STOP2 and HSL APIs
• UI.js - User interface
• Geometry.js - Calculates the vehicle's position
• Trip.js - Trip object (contains the list of stops & other data)
• Logger.js - Error and debug logging logic

Development workflow

In the root of the front folder, run the following commands:

• npm install - Install dependencies
• webpack - Bundle all of the code and the dependencies into a single JavaScript file, dist/bundle.js. Remember to run this every time you edit the files

Usage

• Open index.html

back

Docker-container with mosquitto listening to ports 1883 (MQTT) and 9001 (websocket).

Usage

In the project directory:

docker build -t mosquitto -f back/Dockerfile .
docker run -p 1883:1883 -p 9001:9001 mosquitto

Tests can be run locally (inside Docker):

docker run -t -v `pwd`:/build mosquitto /build/tests/integration.sh
