Bootloader

The Mantle Bootloader class is responsible for instantiating the application/container and load the framework given the current context. It removes the need for boilerplate code to be included in projects but still allows for the flexibility to do so if they so choose. This works well to support running Mantle as apart of a alleyinteractive/mantle-based plugin OR in isolation in a larger codebase.

The core of the bootloader is this:

bootloader()->boot();

Running that line of code will instantiate the application and loading the framework given the current content.

You can also use the bootloader with your own custom application instance (like we're doing in alleyinteractive/mantle):

use Mantle\Application\Application;

$application = new Application();

// Perform some bindings, override some contracts, etc.

// Boot the application with your custom instance and custom bindings.
bootloader( $application )->boot();

Mantle is flexible enough to require no application bindings or allow you to override all of them. It's up to you.

The bootloader will attempt to boot the relevant application kernel given the current context. The kernel will then boot and setup the application.

Supported Contexts

Web

The web context will boot the HTTP application kernel (Mantle\Framework\Http\Kernel) which can be overridden by an application binding. The HTTP kernel will send the current request through Mantle Routing on the parse_request WordPress action.

Console

Using the bin/mantle console application included with Mantle OR running a command via WP-CLI will boot the console kernel (Mantle\Framework\Console) which can also be overridden by an application binding.

If we're running in WP-CLI mode, the application will register a wp mantle command that will proxy the request to the console application. If we're running the bin/mantle console application, the application will handle the request fully and then terminate.
