Updating the web app
In this section, we will develop the code needed to display the data in real time inside the web app, as well as provide an interface, using which we can turn on/off the LED.
We will get started by adding a toggle switch component. We will use the ngx-ui-switch (https://github.com/webcat12345/ngx-ui-switch) for the same.
From inside the web-app-base folder, run the following command:
npm install ngx-ui-switch -save
We will use the ng2-charts https://valor-software.com/ng2-charts/ for plotting charts of our temperature and humidity values. We will install this module as well by running the following command:
npm install ng2-charts --save npm install chart.js --save
This will install the toggle switch and ng2-charts
