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: "This is using the net/http package's default HTTP client to request the index.html resource."

A block of code is set as follows:

POST /login HTTP/1.1
Host: myprotectedsite.com
Content-Type: application/x-www-form-urlencoded
Content-Length: 38

username=myuser&password=supersecretpw

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

go run main.go

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: "In this case, you will receive a status code of 500 Internal Server Error."
