Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can now simply navigate to the IP address of the computer or Pi on which the application is running, followed by port 3000."

A block of code is set as follows:

var request = require('request');
var sensorLib = require('node-dht-sensor');

Any command-line input or output is written as follows:

sudo npm install express request

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "You can now just click on Stream to access the live stream from the camera."
