Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

import path from 'path'
const CURRENT_WORKING_DIR = process.cwd()
app.use('/dist', express.static(path.join(CURRENT_WORKING_DIR, 'dist')))

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

{
    "presets": [
      "env",
      "stage-2",
      "react"
    ],
    "plugins": [
      "react-hot-loader/babel"
    ]
}

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

npm install babel-preset-react --save-dev

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."

Warnings or important notes appear like this.

Tips and tricks appear like this.
