Advanced Express Web Application Development

Overview of this book

Building an Express application that is reliable, robust, maintainable, testable, and can scale beyond a single server requires a bit of extra thought and effort. Express applications that need to survive in a production environment will need to reach out to the Node ecosystem and beyond, for support.You will start by laying the foundations of your software development journey, as you drive-out features under test. You will move on quickly to expand on your existing knowledge, learning how to create a web API and a consuming client. You will then introduce a real-time element in your application.Following on from this, you will begin a process of incrementally improving your application as you tackle security, introduce SSL support, and how to handle security vulnerabilities. Next, the book will take you through the process of scaling and then decoupling your application. Finally, you will take a look at various ways you can improve your application's performance and reliability.

Feature: Delete a project


Let's add a delete button to our form for the feature Delete a project.

Let's make a change to ProjectView and add a new event to the events hash, called delete, which calls the delete method. We add a delete method, which destroys the model and removes ProjectView. We then call repository, removing RepositoryListView.

    events: {
      ...
      "click button.delete": "delete",
    },

    delete: function () {
      this.model.destroy();
      this.remove();
      this.repository({editMode:false});
    },

Let's make a change to ProjectListView and add a collection event handler to initialize. The event handler calls the remove method when an item is removed. The remove method grabs the model's attributes and searches the Projects collection, removing the item when finding it.

    initialize: function () {
      ...
      this.collection.on("remove", this.remove, this);
    },

    remove: function (removedModel) {
      var removed = removedModel.attributes;
