#247 Offline Apps Part 1

With the release of Rails 4.0.0.rc1 it's time to try it out and report any bugs. Here I walk you through the steps to upgrade a Rails 3.2 application to Rails 4. (12 minutes)

Here I demonstrate how to perform bulk API operations though a single request using Rack middleware. This is great if you need to trigger multiple actions at once such as if the user goes offline. (18 minutes)

By default, Rails will render a static error file when an exception occurs in production. Here you will learn how to fully customize this behavior and render dynamic error pages. (11 minutes)

Rails commands, such as generators, migrations, and tests, have a tendency to be slow because they need to load the Rails app each time. Here I show three tools to make this faster: Zeus, Spring, and Commands. (8 minutes)

Learn how to add performance tests that automate benchmark and profile reports. Here I show how to find the bottlenecks to optimize a page. I also show how to compile Ruby with gcdata to get information about memory usage. (16 minutes)
