dashboard/: Web app to manage the project
If you use PlatformIO, these libraries are already configured on the project.
For the dashboard we use Angular.js as a framework to develop it, as a requirements we don't need anything but a web server like apache or nginx. To change the address of the API within the dashboard you have to change a line in the services/MainService.js file.
app.service('MainService', ['$http', function ($http) {
var urlBase = 'http://apiaddress:8080';
...
We use a MVC schema to develop the app.
To draw charts we call the google charts library, with it we draw 2 different kinds of charts.
- Calendar charts:
- Line charts:
In our dashboard we can control the status of our mailbox (doors and letters) in real time, besides that we can see the temperature and humidity on the fly.
All communications is done via HTTP REST services. We have an REST service made in Python and Flask. Persistence is achived using MongoDB for storing events and Redis for hadling the state of the doors.
All infraestructure is based in Docker both in development and in production. Our production machine is a Ubuntu Server 16.04 hosted in Azure.
