The Themosis framework application structure is following the Laravel framework one, at least on its root directory.
Compared to a classic installation, WordPress is defined as a dependency and installed on its own htdocs/cms public subdirectory.
Just like previous versions of the Themosis framework, you can still develop your custom theme for the front-end/user facing content and custom plugins in order to extend WordPress and its administration.
However, we have brought a new central app directory to the stack to help you better manage your code.
On this guide, we'd like to give you some details about the choices made for the directory structure and give you some development recommendations for your custom WordPress application. But of course, you're free to organize your application however you like.
When opening your application in your code editor or IDE, you should find the following files and directories:
+-- app/
| +-- Console
| +-- Exceptions
| +-- Forms
| +-- Hooks
| +-- Http
| +-- Controllers
| +-- Models
| +-- Providers
+-- bootstrap/
+-- config/
| +-- app.php
| +-- ...
| +-- wordpress.php
+-- database/
+-- htdocs/
| +-- cms/
| +-- content/
| +-- index.php
| +-- wp-config.php
+-- resources/
| +-- languages/
| +-- views/
+-- routes/
| +-- api.php
| +-- channels.php
| +-- console.php
| +-- web.php
+-- storage/
+-- tests/
+-- vendor/
+-- .env
+-- composer.json
+-- artisan
+-- LocalValetDriver.php
+-- server.php
+-- wp-cli.ymlThe biggest change to the directory structure is the adoption of the app directory in order to develop your application.
The app directory stores all your classes in order to extend or customize your application. More about the app folder below.
The bootstrap directory contains the app.php file which bootstraps the application. It also holds a cache directory containing generated files by the framework and Laravel packages.
The config directory contains all the global or shared configurations for your application.
The database directory stores your migration and seeder files.
The htdocs directory is your web server public directory.
The resources directory stores your shared views as well as language translations files.
The routes directory holds your application routes.
The storage directory stores framework temporary files, logs, sessions, and any custom files your application need to handle out of the public folder.
The tests directory stores all your unit tests.
The vendor directory is created by Composer and holds all your application dependencies.
This is not a "best practice" chapter but some explanations on the changes made to the structure of the Themosis framework.
Your journey starts by defining routes. On the previous versions of the Themosis framework, a routes.php file was defined into the resources directory of the theme. From that file, you list all routes for your application.
We decided to move the routes file, just like in Laravel, to the application routes directory instead. This change avoid the mix of routes definitions between the file stored in your theme and any other routes file stored in your custom plugin.
From now on, all routes for your application should be defined into the routes/web.php file stored at project root.
The new plugin structure provides a routes.php file at plugin root in order to let you define custom routes. This is still useful, especially if your intention is to share code across multiple projects.
The new theme structure mainly handles front-end assets and views of your application.
Just like any classic WordPress theme is doing, the new theme provided by the Themosis framework, is to simply render the content of your application - the HTML. For this, we have moved the views directory at theme root and provided default view files based on the Underscore - _S theme.
If you feel like you need to customize your application by changing something into the WordPress administration, providing some shared utilities or simply adding some logic, we suggest you to put it into the new app directory located at project root, or develop a custom plugin or a custom PHP package.
The new theme is also configured with Laravel Mix and is already setup to handle your front-end needs.
Please read the theme guide for more details.
You could provide views for your entire application through the resources/views directory located at application root. However, we recommend to use it for shared views or views used to customize the WordPress administration.
In order to extend WordPress, the Themosis framework provides a new mechanism based on Hookable classes. Those classes allow you to extend WordPress and provides a register() method, just like Service Providers.
When using Hookable classes, you have access to all WordPress functions and APIs. Those classes are stored in the app/Hooks directory.
By default, the framework contains 3 Hookable classes responsible to modify the behavior of WordPress, load core assets to the WordPress administration and register WordPress widgets:
If you provide features that do not need WordPress functions or classes, please use a Service Provider. Read the Service Provider guide for more information.
Please read the Hook guide to learn more about the new Hookable API.
As mentioned earlier, the Themosis framework now provides a unique and central app directory where you can store your application code.
The app directory is where you store your application controllers, models, commands, forms, hooks, widgets and any other classes your application might need to work. The directory is namespaced under App and is autoloaded by Composer using the PSR-4 autoloading standard.
The app directory contains many subdirectories that are added when you're using the make command from the Artisan CLI tool provided by the framework.
However, here is a list of the default subdirectories you may find under the app folder:
The Console directory contains all the custom Artisan commands for your application. These commands may be generated using the make:command command. This directory also houses your console kernel, which is where your custom commands are registered and your scheduled tasks are defined.
The Exceptions directory contains your application's exception handler and is also a good place to place any exceptions thrown by your application. If you would like to customize how your exceptions are logged or rendered, you should modify the Handler class in this directory.
The Forms directory contains the custom forms of your application. Please read the form guide for more information.
The Hooks directory contains all hookable classes used to customize or extend WordPress. Please read the hook guide for more information.
The Http directory contains your controllers, middleware (and form requests). Almost all the logic to handle requests entering your application will be placed in this directory.
This directory does not exist by default, but will be created for you if you execute the make:mail Artisan command. The Mail directory contains all of your classes that represent emails sent by your application. Mail objects allow you to encapsulate all the logic for building an email in a single, simple class that may be sent using the Mail::send method.
The Providers directory contains all the service providers for your application. Service providers bootstrap your application by binding services in the service container, registering events, or performing any other tasks to prepare your application for incoming requests.
In a fresh Themosis application, this directory will already contain several providers. You are free to add your own providers to this directory as needed.
The Widgets directory contains all of your WordPress widgets. You can create a new widget by using the make:widget Console command and then register it within the Widgets hookable class.
Depending on your WordPress installation, Widgets may no longer be loaded as those are handled through Gutenberg.
