Why I JavaScript… for reals

Headless WordPress, yas!

Create really custom UI

It is a great time to be a JS developer!

Why PHP?

@royboy789

Why PHP?

PHP isn’t going anywherePHP is stableIf you level up as a developer, there are just as many PHP frameworks as good JS frameworks

@royboy789

WordPress is PHP

@royboy789

So much PHP!

Ever notice those sneaky <?php tags?The REST API is also built in PHP

The P in LAMP, LEMP, LNMP, LAPP, WAMP, MAMP, XAMP(<- this one)P(<- sometimes this one)

@royboy789

WordPress & Node

For the foreseeable future, there is no reason that WordPress will be magically rebuilt on node.

If it is going to be rebuilt, it will stay PHP, probably be PHP7 amazing.

@royboy789

API can be used without JS

@royboy789

API your stuff with PHP

You can use the REST API’s PHP classes to run the functions a route does, except it is all done server side without

wp_safe_remote_get/post

$request = new WP_REST_Request( 'GET', '/wp/v2/posts' );

@royboy789

PHP Frameworks

Just like there are JS frameworks to learn as you become more advanced, there are PHP frameworks. You can build advanced functionality with one of these, still communicating to your WordPress data

Laravel, Symfony - popular, good

Phalcon, CakePHP - not as popular, still good

Ok, but seriouslyI mean, you’re wearing an Angular hat.

Use JS for what it is good for

PHP Means BusinessDon’t mess with it.

@royboy789

Business Logic Code

Business logic is the code that is, functionality wise, the meat of your business.

Ex: If you run a Woocommerce store, the creation of the order, payment processing, and anything else check out related that happens before the “thank you” page- Business Logic

@royboy789

Business Logic in API

JavaScript is best used for UI

leave it that way!

JavaScript can hit the APIAPI will do all the logicSend back appropriate data to modify UI

@royboy789

Business Logic in API - Example

1. Your JS checkout app sends call with data to API

2. API handles all Woo code to create order

3. API handles all Woo code to create payment

4. API handles all Woo code to finalize order

5. Data sent back is just the final success / failure, and

order ID (and associated meta)

@royboy789

Extend the API for Business Logic

As you need more business logic code, extending the API

is the way to go… and that is done (should be done) in

PHP

Create custom routes & endpoints for your business

logic

Use the REST API to create your own REST API
