Why do I care about best practices?

The Chinese experience...

Developed multiple Drupal and Drupal Commerce sites

Managed the development of Commerce Kickstart v2

Managed the development of Commerce Guys Marketplace

Used those best practices on my own e-commerce website

Couple de Huit

What did I learn?

It’s easy to maintain a Drupal site

Small websites are built the same way as big websites

Making architectural changes is simple on a Drupal site

It's all about tools and techniques

TOOLS

Version control

Easily save and revert your work

Manage projects with multiple developers

Use Git

Great flexibility on branching and merging

Code review

Audit specific pieces of code

Track down problems that might arise

We use Github

Powerful *pull request* and *fork* workflow

Drush

Drupal without Drush is like life without mobile phones... you know you managed just fine but now you just can't imagine how

Drush

• Login MySQL database: drush sql cli
• Install the site from scratch: drush si
• Run cron: drush cron
• Run pending database updates: drush updatedb
• Revert/update features: drush fra
• Run migrations: drush mi
• ...

Development Modules

• Devel
• Drupal for firebug
• Coder
• XDebug

Automated testing

• Simpletest
• Behat/Mink
• Selenium

Preformance testing

• JMeter
• Apache Bench

Now what?

TECHNIQUES

Architectural plan

Think hard before clicking

Development environments

Everyone should be able to test in live conditions

Installation profile

Install from scratch at any time

Whaaaaat?

Your own profile

Need a starting point?

Configuration ==> files

Features

drush feature-revert

Migrate

drush migrate-import

An example

Updates

drush updatedb

Make files

Forget about randomly patched modules in the repository

What you will get

Predictable development workflow

Reusable components across projects

Better tracking of configuration changes

Better integration with automated testing
