Conventions used

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, database tale names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows:
"This tells npm that our package depends on the URL and express modules."

A block of code is set as follows:

router.get('/v1/item/:itemId', function(request, response, next) {
  console.log(request.url + ' : querying for ' + request.params.itemId);
  catalogV1.findItemById(request.params.itemId, response);
});

router.get('/v1/:categoryId', function(request, response, next) {
  console.log(request.url + ' : querying for ' + request.params.categoryId);
  catalogV1.findItemsByCategory(request.params.categoryId, response);
});

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

router.get('/v1/:categoryId', function(request, response, next) {
  console.log(request.url + ' : querying for ' + request.params.categoryId);
  catalogV1.findItemsByCategory(request.params.categoryId, response);
});

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

$ npm install -g express

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:

Warnings or important notes appear like this.
