What’s this talk all about?

Open source, history and growth. (Story time.)

Laravel. (Cool stuff!)

Let’s go back in time to 2011!(Imagine wibbly-wobbly effect.)

Working in Aberystwyth

•Using CodeIgniter.

•Simple projects.

•No side projects.

•Not “known” for anything.

Contributed to CodeIgniter

Started out with graphic contributions. Accepted by Phil Sturgeon. (Thanks Phil!)

Rejected by EllisLab. Started to outgrow the framework.

Time for a new framework!

VS

Laravel 2.something

• Simple website. • Great documentation. • Clean and simple code. • No users. • Mystery author.

Community time!• Became active in IRC. • Then: 3 people. Now: ~600. • Started writing tutorials. • Tutorials got attention. • Released Code Happy. • CodeIgniter users shifting across.

Involvement (L3)• Started submitting fixes and features to the pre-

release Laravel 3.

• Helped build/design the website for Laravel 3 (and later 4).

• Did lots of visual work for the framework including splash screens.

• Built popular bundles for Laravel 3.

• Help build a welcoming and helpful community.

Taylor Otwell(Grand Master Artisan)

Laravel 3 had it’s flaws.

TESTING :(

EXTENSIBILITY :’(

Time for Laravel 4!• Taylor started work on Laravel 4.

• One of first users when it was built on Silex.

• Feedback loop.

• Exciting new architecture.

• Stable release cycle.

• Powered by Composer (Thanks Jordi!)

• Component-based framework.

• Uses plenty of open source! (Some Symfony, thanks Fabpot!)

The Promise• No preaching!

• No moaning about other frameworks.

• Just cool features!

• Intro to IOC / DI.

Laravel• Coding should be enjoyable. • Code can be art. • Clean and simple syntax. • Your framework should grow with you. • A complete platform, end to end. • Components that solve real problems.

• Embrace open source, and make use of it where possible.

• Give back to open source community where possible.

• A community of friendly Artisans.

Automatic type-hinted dependency resolution and injection inversion of control container.

Magic Code Box

Basic Usage

The same something!

Automatic Class Resolution( From the magic box! )

Type-hinted Dependency Resolution

Tricking the magic box.

Let’s do something cool.

Implementations

( Shameless colour schemes promo.)

Bind the interface.

( Still have no shame, I mean, just look at the beard.)

Use our new service.

Imagine username here.

Interchangeable!

Components / Services

Facades!

Resolve the service from the container (magic box) by known key.

Forward the method call to the real service instance with parameters.

Replacing components.

Why bind?

The Magic Box Revisited• Not just a data store!

• A number of binding methods.

• Automated class resolution.

• Automatic dependency injection.

• Interface binding.

• Service replacement / mocking.

• Extensible framework.

• Facades without the testing problems.

• The heart of the framework!

• illuminate/container

( Not so magic anymore, hopefully! )
