Handling Page Transitions on Single Page Web Apps

Real world application with a lot of pages (or "screens") have to deal with problem managing the pages' DOM and memory efficiently and at the same provide a nice smooth transition effect between pages. This is not a real problem when you do it in native apps since Android or iOS already handle the hard work for you, but when come to JavaScript, HTML, and CSS, running on mobile browsers, this is the real challenge.

There are 2 common approaches to solve this problem:

• Approach 1: Keep all the pages in the DOM tree, use CSS (for example display) to transit between pages.

Install Apache with Homebrew

Installing Apache

# Start by stopping the built-in Apache, if it's running, and prevent it from starting on boot.
# This is one of very few times you'll need to use sudo:
sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

# We need to tap homebrew-dupes because "homebrew-apache/httpd22" relies on "homebrew-dupes/zlib"

and install Apache 2.2 with the event MPM, and we'll use Homebrew's OpenSSL library

 * Example webpack.config.js for an AMD project (or AMD + CJS mixed project).
 * This file should be at the root of your project.
 *
 * This can then be used in combination with Karma as well
 * Just load this file and pass it to karma.webpack key
 * (see https://github.com/webpack/karma-webpack#alternative-usage)
 *
 * This example is a bit extreme. Typically in webpack, you don't need much
 * configuration if you have nicely behaving code and work with correctly
