Silex Base-Application

Basic Silex application, configured to use common providers.

About

Most of the applications developed by mksec use the same common infrastructure with Silex: There's a class inherited from the Silex Application class, which configures the error- and exception handlers. Although the providers depend on the individual applications, some of them are common for all of them.

This repository provides some classes providing the basic infrastructure, that may be used as base classes for the applications to build, making them more simple, as common code doesn't need to be repeated.

Installation

Simply add mksec/silex-base as a dependency for your project with composer:

Usage

Using the basic application classes is pretty easy: Just use one of the classes below instead of \Silex\Application and you are done. For specialized applications you may want to implement a class inheriting from one of the base classes.

Classes

• BaseApplication

  The BaseApplication class is a simple Silex Application with the Error- and ExceptionHandler registered. It may be used for simple applications without an UI (e.g. APIs).

  Notice: The exception handler of Silex will catch all exceptions while handling a request. In addition, the ErrorHandler will convert any errors and warnings (e.g. reading from a non-existing file) to exceptions, that will be handled by the same exception handler of Silex. However, Silex doesn't catch fatal exceptions (e.g. ClassNotFoundException) or exceptions thrown outside a running controller. You can access the Error- and ExceptionHandler with the core.error_handler and core.exception_handler keys, e.g. to set a custom exception handler returning the error 500 page.

  You can use the catchAllExceptions() method to tell the ExceptionHandler to route exception events to the Silex event handlers. Please read the docs before using this method!

• BaseUiApplication

  The BaseUiApplication extends the BaseApplication with the Twig and Asset serivce-providers registered. It also uses the CacheTrait to use an application-wide cache path, which may be set in the app.cache path.

  To use this class, you'll need to add additional dependencies:

  The Web Profiler may be activated with the enableProfiler() method after the other providers have been registered. You'll also need to add additional development dependencies:

  Additional dependencies may be required depending on other providers you're using. See the README for the Silex Web Profiler for further information.

There could be a lot more of sub-classes for any kind of Applications. However, this might be inefficient, as there're too many combinations of services for higher classes:

• There're situtions to use the MonologServiceProvider in any kind of application, so there's no sense to add extra classes just do get monolog in all of them. It is easier to just register the MonologServiceProvider if needed.
• The same goes for the security components (SecurityServiceProvider, RememberMeServiceProvider, SessionServiceProvider): Imagine an application with stateless authentication - there's no sense to use the latter two here.
• Interactive applications might use the CsrfServiceProvider and FormServiceProvider. However, their dependencies highly depend on the final application, i.e. if the default form templates will be used, the TranslationServiceProvider is required, but for custom templates it might be superfluous.

Providers

• ThemeServiceProvider

  The ThemeServiceProvider may be used to dynamically determine the paths for Twig views and assets. Although it is meant to be used with the BaseUiApplication, it is compatible with a plain Silex Application.

  A theme may have a file named assets.php in its root to return an array of named packages used (e.g. Bootstrap, jQuery, ...) in the template. One may change this list easily by extending the assets.named_packages key of the $app e.g. to switch the used CDN:

  The theme may also provide a file named assets.manifest.json in its root to specify versions of assets the theme owns (not named packages!):

  Notice: This feature was introduced in symfony/assets version 3.3!

  The manifest file can be generated by several tools like webpack. However, for just generating the manifest, you may use the bin/asset-manifest tool. The first argument is the path of your theme, following arguments are the assets:
