User interface components for the GottaEat food delivery service application. The project consists of four distinct modules that depend upon on another to function properly.

##How To Run In order to run the demo you need to execute the following steps:

1. Update the Pulsar OAuth2 credentials file in ALL of the /src/main/resources/META-INF/application.properties files. Replace the value of the pulsar.oauth2.credentials-url property to point to your local OAuth2 credentials file that you downloaded from the SN Cloud.

2. Start the driver-location-service by changing into that module's subdirectory and running the following command:

   "mvn clean compile quarkus:dev"

   This will start the web service, and you can verify that it is running by visiting http://localhost:8080/index.html

3. Next, you should start the driver-simulator by changing into that module's subdirectory and running the following command:

   "mvn clean compile quarkus:dev"

   This will start generating synthetic driver location data. You can specify the number of drivers to simulate as well as the Latitude/Longitude of the starting centriod for the drivers.

   You can verify that this service is running by refreshing the http://localhost:8080/index.html page to confirm new records are showing up based on the timestamps.

4. You can then start the driver-tracker-websocket service that provides real-time updates of the driver position by changing into that module's subdirectory and running the following command:

   "mvn clean compile quarkus:dev"

   To track an individual driver you can visit http://localhost:8005/driver-tracker.html

   Or if you want to see all the drivers in a current geographical area, then you can visit http://localhost:8005/grid-tracker.html

5. Finally, you can start the driver-location-analytics-service by first changing into that module's subdirectory and running the following command:

   "mvn clean compile quarkus:dev"

   This will start the REST service that calculates the Grid used by the front service, which must be started separately by changing into the src/main/webapp subdirectory and running npm start to launch the UI.

   This should automatically open a web broswer pointing to http://localhost:3000 that shows an interactive map of the driver density by H3 grid.
