Drupal 8 is coming! But what decisions can you make now on your current or new Drupal 7 sites to make transitioning to Drupal 8 easier?




This page is based on David Reid's presentation DrupalCon Austin 2014: FUTURE-PROOF YOUR DRUPAL 7 SITE. Dave covers new features available in Drupal 8, and how you can use those new features now in Drupal 7. Dave Ried also did a similar presentation at DrupalCon Amsterdam 2014.

"This is a Vagrant profile for installing a fully functioning Drupal system that mirrors what people at Penn state use to jump start development of new and existing systems.

Why use this

This allows you to jump start development of a Drupal site using modules that the Penn State Drupal User’s Group recommends. While you won’t need everything included here, you will find that you end up using the same modules on almost all build outs. Nittany’s Vagrant server is a great place to learn both about how Drupal and Linux boxes are setup, but also to experiment and practice system administration in a setup similar to those services provided by the VMHosting group (or any other Virtual hosting cluster).

There are more modules then what’s provided here and we’ll be adding more recipes in the future but the intention of this script is to do the heavy lifting of getting a new site up and do so in a standardized manner.

Store & Sync Data Instantly
Build realtime mobile and web apps in minutes using client-side code and our powerful API. Save time. Delight your users.

"Jdrop provides a place to store JSON data in the cloud. The initial application is for storing performance data gathered from mobile devices. It's hard to analyze large amounts of information (HTTP waterfall charts, HTTP headers, document source, etc.) on a mobile device. Jdrop lets you gather this data on the mobile device but analyze it remotely on a larger screen."

"Show Slow is an open source tool that helps monitor various website performance metrics over time. It captures the results of YSlow, Page Speed, WebPageTest and dynaTrace AJAX rankings and graphs them, to help you understand how various changes to your site affect its performance."

"An Introduction to IndexedDB

IndexedDB offers a powerful way to store and retrieve data in the browser. As with server-side databases, IndexedDB allows us to generate keys, search data, or sort it by a particular field. In this article, we’ll dig into the IndexedDB API by building a to-do list manager. But first, let’s look at some of the concepts around databases and IndexedDB.
What is IndexedDB?
IndexedDB is an asynchronous, transactional, key-value object store. That’s a lot of concepts to introduce in one sentence, but I’ll try to explain them.
Asynchronous means that IndexedDB won’t block the user interface. Operations happen “soon” rather than immediately. This allows the user interface to respond to other input. To contrast: localStorage is synchronous. Operations are processed immediately, and nothing else will happen until the operation completes. Large reads and writes can slow your application significantly.

Transactional means that operations in IndexedDB are all-or-nothing. Should an operation fail for some reason, the database will revert to its previous state. You’ll never have a partially-written record with an IndexedDB database.

A key-value object store means that each record is an object, as opposed to a row. Traditional databases use a relational model. Data is organized by table, typically with relationships between the values of one table and the keys of another (Figure 1).

In a key-value object store, each record is a self-contained object. It may, but usually doesn’t have a relationship to records in another object store. Each record may even differ radically from other objects in the same store."

Trying to setup a website for selling online services with recurring billing cycles. No need to shipping feature. Wanted to use Commerce Kickstart, but after reading Bojan's comment on https://www.drupal.org/node/1732042 I see that it's better to start with clean Drupal Commerce install, but I am confused which modules I need to install. Here's a .make file that has Drupal, Commerce, Dependencies, and Commerce License:

This is a Vagrant configuration to provision LAMP stack with tools required for Dupal development.
What does it do?

Provisions full stack virtual machine and installs Drupal 7 and Drupal 8 using only 1 command - vagrant up .
Why?

Sometimes you just want to start working on a module or module-port and there is no sandboxed environment that allows you to just start. Download this and provision a virtual box - and you are ready to go!
