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: "Create the index.js file."

A block of code is set as follows:

// EddieBot webhooks

const express = require('express')
const bodyParser = require('body-parser')
const app = express()
app.set('port', (process.env.PORT || 5000))

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

npm init

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: "Click on the Get Started button at the bottom of the chat window."
