In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "To set the environment our node server runs in, we set an environment variable NODE_ENV
to the environment we want to run node in."
A block of code is set as follows:
<!DOCTYPE html> <html> <head> <title>{TITLE}</title> <link rel="stylesheet" href="/stylesheets/style.css" /> </head> <body> <header id="banner"> <h1>Awesome Chat</h1> </header> {CONTENT} <footer> Hope you enjoy your stay here </footer> </body> </html>
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
doctype 5 html block head title= title link(rel='stylesheet', href='/stylesheets/style.css') body header#banner h1 Awesome Chat block content footer Hope you enjoy your stay here
Any command-line input or output is written as follows:
$ express awesome-chat $ cd awesome-chat $ npm install
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Now you can enter your message in the message box in one of the browsers and click Send. You will see it appear on the message area of both the browsers."
