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: “One of the browser’s security guarantees is that an HttpOnly cookie will never be read out by a script.”

A block of code is set as follows:

const generalProxy = new Proxy(() => generalProxy, {
  get(target, name) {
    if (name === Symbol.toPrimitive) {
      return () => ({}).toString();
    } else {
      return generalProxy();
    }
  },
});

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

# Initialize a new Node.js project
npm init -y
# Add the http-server package to the dependencies
npm i http-server --save

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

npx pilet debug

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “As an example, when micro frontend 2 (MF2) from Figure 15.2 is loaded, it has to register Component B in the Component Registry.”
