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 'isomorphic-fetch';

      (async () => {
          const res = await fetch(...); // already polyfilled
      })();

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

async getInitialProps({store}) {
  await store.dispatch({type: 'FOO', payload: 'foo'}); // this could be async
  return {custom: 'custom'}; 
}

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

 $ npm install isomorphic-fetch --save

Bold: Indicates a new term, an important word, or words that you see onscreen. 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."
