It contains all the supporting project files necessary to work through the book from start to finish. 6 | ## About the Book 7 | This book targets developers who want to enrich their development skills by learning how 8 | to develop scalable, server-side, RESTful applications based on the Node.js platform. You 9 | also need to be aware of HTTP communication concepts and should have a working 10 | knowledge of the JavaScript language. Keep in mind that this is not a book that will teach 11 | you how to program in JavaScript. Knowledge of REST will be an added advantage but is 12 | definitely not a necessity. 13 | ## Instructions and Navigation 14 | All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02. 15 | 16 | 17 | 18 | The code will look like the following: 19 | ``` 20 | router.get('/v1/item/:itemId', function(request, response, next) { 21 | console.log(request.url + ' : querying for ' + request.params.itemId); 22 | catalogV1.findItemById(request.params.itemId, response); 23 | }); 24 | router.get('/v1/:categoryId', function(request, response, next) { 25 | console.log(request.url + ' : querying for ' + 26 | request.params.categoryId); 27 | catalogV1.findItemsByCategory(request.params.categoryId, response); 28 | }); 29 | ``` 30 | 31 | ## Related Products 32 | * [Mastering Node.js - Second Edition](https://www.packtpub.com/web-development/mastering-nodejs-second-edition?utm_source=github&utm_medium=repository&utm_campaign=9781785888960) 33 | 34 | * [Learning Node.js Development](https://www.packtpub.com/web-development/learning-nodejs-development?utm_source=github&utm_medium=repository&utm_campaign=9781788395540) 35 | ### Download a free PDF 36 | 37 | If you have already purchased a print or Kindle version of this book, you can get a DRM-free PDF version at no cost.
