Overview of this book

Node.js builds fast, scalable network applications while MongoDB is the perfect fit as a high-performance, open source NoSQL database solution. The combination of these two technologies offers high performance and scalability and helps in building fast, scalable network applications. Together they provide the power for manage any form of data as well as speed of delivery. This book will help you to get these two technologies working together to build web applications quickly and easily, with effortless deployment to the cloud. You will also learn about angular 4, which consumes pure JSON APOIs from a hapi server. The book begins by setting up your development environment, running you through the steps necessary to get the main application server up-and-running. Then you will see how to use Node.js to connect to a MongoDB database and perform data manipulations. From here on, the book will take you through integration with third-party tools to interact with web apps. You will see how to use controllers and view models to generate reusable code that will reduce development time. Toward the end, the book supplies tests to properly execute your code and take your skills to the next level with the most popular frameworks for developing web applications. By the end of the book, you will have a running web application developed with MongoDB, Node.js, and some of the most powerful and popular frameworks.

Preface

Iterating by adding an image removal capability


At this point, I think our application is pretty awesome, but there's something missing that's nagging me. During testing, I've been creating all kinds of new images and uploading them to the application, but it's starting to get a bit cluttered and messy. It dawned on me that the most obvious thing that's missing is the ability to delete an image!

In reality, I left out this feature on purpose so that we could use this opportunity to incorporate a completely new functionality that touches almost every area of the application. This seemingly simple addition is actually going to require the following changes:

  • Update routes.js to include a new route to handle Delete requests
  • Update controllers/image.js to include a new function for the route
  • This should not only remove the image from the database, but also delete the file and all related comments
  • Update the image.handlebars HTML template to include a Remove button
  • Update the public/js/scripts.js file...
