Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You should see the same result, but without the test.js file stored on the disk." A block of code is set as follows:

@Injectable()
class Socket {
 constructor(private buffer: Buffer) {}
}

let injector = ReflectiveInjector.resolveAndCreate([
  provide(BUFFER_SIZE, { useValue: 42 }),
  Buffer,
  Socket
]);

injector.get(Socket);

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

let injector = ReflectiveInjector.resolveAndCreate([
  provide(BUFFER_SIZE, { useValue: 42 }),
  Buffer,
  Socket
]);

Each code snippet that is in the repository with the code from this book starts with a comment with its corresponding file location:

// ch5/ts/injector-basics/forward-ref.ts

@Injectable()
class Socket {
  constructor(private buffer: Buffer) {…}
}

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text surrounded by quotes, or like this: "When the markup is rendered onto the screen, all that the user will see is the label: Loading…."
