The component provides a wrapper over the `symfony/var-dumper` library. This component sends dumps directly to the browser within HTTP workers or to the `STDERR` output in other environments. [**Documentation**](https://spiral.dev/docs/basics-debug#spiral-dumper) Installation ------------ [](#installation) Use [Composer](https://getcomposer.org/) to install the package: ``` composer require spiral/dumper ``` Usage ----- [](#usage) ### Symfony VarDumper [](#symfony-vardumper) In your code: ``` dump($variable); ``` In an application using **RoadRunner**, you cannot use the `dd()` function. But the package provides an alternative `\rr\dd()` function. To use it, you need to add `Spiral\Debug\Middleware\DumperMiddleware` in the application, after `ErrorHandlerMiddleware`: ``` use Spiral\Bootloader\Http\RoutesBootloader as BaseRoutesBootloader; use Spiral\Debug\Middleware\DumperMiddleware; use Spiral\Http\Middleware\ErrorHandlerMiddleware; final class RoutesBootloader extends BaseRoutesBootloader { protected function globalMiddleware(): array { return [ ErrorHandlerMiddleware::class, DumperMiddleware::class, // ... ]; } // ... } ``` ### Buggregator [](#buggregator) The package provides a built-in integration with the [Buggregator](https://github.com/buggregator) service via [Trap](https://github.com/buggregator/trap) library. 1. Run a Buggregator server: - Full server using Docker: ``` docker run --rm --pull always -p 127.0.0.1:8000:8000 -p 127.0.0.1:1025:1025 -p 127.0.0.1:9912:9912 -p 127.0.0.1:9913:9913 ghcr.io/buggregator/server:latest ``` - Mini server using PHP: ``` ./vendor/bin/trap ``` 2. Use `trap()` function instead of `dump()` to send dumps to the Buggregator server: ``` trap($variable); ``` License ------- [](#license) The MIT License (MIT).
