Platform?
Platform = Next Generation
1. Philosophy 2. Process 3. Projects Next Generation
Philosophy
Backwards compatibility Design for the majority Decisions, not options
The user comes first
The user comes first
User Experience
Developer User Experience
DUX
Developers Are Users Too Philosophy:
WordPress Sucks Spoiler:

Why?

Process
How WordPress Works
Incremental development = Organic growth
“A rolling codebase gathers technical debt” — Ancient Australian proverb

Design For Developers Process:
Rebuilding the Plane While Flying It
WordPress WordPress
Blog CMS Platform WordPress Architecture

1. Write wrappers 2. Test both old and new 3.
Flip the wrapper
Retains Backwards Compatibility Write, Test, Flip
Projects
Set a Standard Projects:
wp_insert_post
wp_insert_post (Why?)
1. Write wp_insert_post WP_Post::create $wpdb->insert( "INSERT INTO $wpdb->posts" ) wp_set_post_categories()
wp_set_post_tags() wp_slash()
2. Test wp_insert_post WP_Post::create $wpdb->insert( "INSERT INTO $wpdb->posts" ) exercise
left to reader wp_set_post_categories() wp_set_post_tags() wp_slash()
3. Flip WP_Post::create $wpdb->insert( "INSERT INTO $wpdb->posts" ) wp_set_post_categories() wp_set_post_tags()
wp_slash() wp_insert_post
3. Flip WP_Post::create $wpdb->insert( "INSERT INTO $wpdb->posts" ) wp_set_post_categories() wp_set_post_tags()
wp_slash() wp_insert_post
WP_Post::create
WP_Post::create WP_Page Woo_Product WP_Revision Jetpack_Comic
Rewrites
<?php add_rewrite_rule( 'archives/date/([0-9]{4})/([0-9]{1,2})/?$', 'index.php?year=$matches[1]&monthnum=$matches[2]' );
Routers $app = new \Slim\App; $app->get('/hello/{name}', function (Request $request, Response
$response) { Slim Framework Route::get('user/{id}', function ($id) { Laravel Symfony class BlogController extends Controller { /** * @Route("/blog", name="blog_list") */ public function listAction() {
'index.php?rest_route=/$matches[1]' ); add_action( 'init', function () { global $wp; $wp->add_query_var(
'rest_route' ); }); add_action( 'parse_request', function () { global $wp; if ( empty( $wp->query_vars['rest_route'] ) ) { return; } // Finally, do something. }); add_rewrite_rule( '^wp-json/(.*)?',
function () { // Much easier. } ); add_rewrite_rule( '^wp-json/(.*)?',
'index.php?year=$matches[1]&monthnum=$matches[2]' ); add_rewrite_rule( 'archives/date/([0-9]{4})/([0-9]{1,2})/?$',
function ( $matches ) { global $wp_query; $args = [
'year' => $matches[1], 'monthnum' => $matches[2], ]; $wp_query = new WP_Query( $matches ); } ); add_rewrite_rule( 'archives/date/([0-9]{4})/([0-9]{1,2})/?$',
add_rewrite_rule( 'login/?$', function () { get_header(); wp_login_form(); get_footer(); } );
1. Write wrappers 2. Test both old and new 3.
Flip the wrapper
Bonus: No More Flushing
Autoloading
Drupal ✓ Joomla ✓ MediaWiki ✓ Magento ✓ WordPress ✗
Autoloading?
Autoloading is a trade-off
15 MB 15,000,000 bytes
Autoloading Load Everything
Composer?
Plugin Dependencies
<?php /** * Plugin Name: Amazing Plugin * Requires: other-plugin,
rest-api */ add_plugin_dependencies( __FILE__, [ 'other-plugin', 'rest-api' ] );
Conflicts? Plugin Dependencies
Already a Problem Plugin Dependencies
Even bigger?
