Conventions used

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

Code in text: 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: "Keycloak supports the authorization_code grant type and the code and token response types."

A block of code is set as follows:

<Header>.<Payload>.<Signature>

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

{
  "access_token": "eyJhbGciOiJSUzI1NiIsI…",
  "expires_in": 299,
  "token_type": "bearer",
  "scope": "profile email",
  …
}

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

$ npm install
$ npm start

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: "Now click on Load OpenID Provider Configuration."
