Delivery Simulator

This project is a delivery simulator that shows the driver's position on the map in real time. The test project was inspired by the Codelivery project created by the School of Net during the FullCycle Marathon.

Technologies

• NodeJs
• PostgreSql
• RabbitMQ
• Google Maps
• WebSocket(Socket.IO)
• Docker

Architecture

There are 3 services developed in NodeJs communicating through the queues using RabbitMQ

• Orders: It is the service where orders and drivers are stored in PostgreSql. When registering an order an event is sent to start the simulator service IMAGEM

• Simulator: Cycles through the latitude and longitude coordinates to simulate the delivery by sending the data to the map service. When delivery is finalized it sends an event to change the status of the Order

• Map: It is the service that is receiving the driver's position sent by the simulator using google maps displays a map showing the driver's real-time position

Google Maps API

You will need a Google Maps key. To get your key from this link.

https://developers.google.com/maps/documentation/javascript/get-api-key?hl=en

Then add your key to the file .env.production

RABBITMQ_HOST=rabbitmq
RABBITMQ_PORT=5672

How add destination

To add new destinations you need to use the Google Maps feature of Create a map. You can access this feature at this link

https://www.google.com/intl/pt-BR/maps/about/mymaps/

Within your map, assemble a route and then export it in KML format. Then just remove all content from the KML file and keep only the latitude and longitude coordinates

Start

Run this command

docker-compose up -d

Then just go to this URL http://localhost:8080
