Compiler

Anything that can be part of the build, especially files using OPcache, should be compiled to ensure the data is available instantly without delays. The only limitation is that the compiler cannot rely on the database, indices, or env.php configuration.

Register

Add your compiler to the pool through YAML configuration.
config/backend/compiler.yaml:

compiler:
  pool:
    my-compiler:
      message: make my-data
      compiler: MyProject\MyModule\App\Compiler\MyData

Implement

Use Lightna\Engine\App\Build::save() to save data into the build:

<?php
 
declare(strict_types=1);
 
namespace MyProject\MyModule\App\Compiler;
 
use Lightna\Engine\App\Compiler\CompilerA;
 
class MyData extends CompilerA
{
    public function make(): void
    {
        $data = [];
 
        // Make your data...
 
        $this->build->save('my-module/my-data', $data);
    }
}

Where:

Use

Use Lightna\Engine\App\Build::load() to load data from the build:

<?php
 
declare(strict_types=1);
 
namespace MyProject\MyModule\App;
 
use Lightna\Engine\App\Build;
use Lightna\Engine\App\ObjectA;
 
class MyModel extends ObjectA
{
    protected Build $build;
    protected array $myData;
 
    public function getMyData(): array
    {
        return $this->myData;
    }
 
    /** @noinspection PhpUnused */
    protected function defineMyData(): void
    {
        $this->myData = $this->build->load('my-module/my-data');
    }
}
