Installation

composer require liquiddesign/nette-log-viewer

Usage

1. Register Presenter in Router

Option A: Using NEON Configuration (Recommended)

Add routes to your config/pages.neon or similar configuration file:

routing:
	routes:
		'log-viewer/view/<file .+>': LogViewer:LogViewer:view
		'log-viewer/download/<file .+>': LogViewer:LogViewer:download
		'log-viewer[/<path .+>]': LogViewer:LogViewer:default

If you extended the presenter in your app namespace (e.g., App\Web\LogViewerPresenter):

routing:
	routes:
		'log-viewer/view/<file .+>': Web:LogViewer:view
		'log-viewer/download/<file .+>': Web:LogViewer:download
		'log-viewer[/<path .+>]': Web:LogViewer:default

Option B: Using PHP Router

Alternatively, add the route in your RouterFactory:

// app/Router/RouterFactory.php
use LogViewer\LogViewerPresenter;

$router[] = new Route('log-viewer[/<action>][/<path .+>]', LogViewerPresenter::class);

2. Access Log Viewer

Navigate to:

https://your-app.com/log-viewer

Note: The log viewer is only accessible when Tracy debugger is enabled (debug mode). This is typically controlled by your config.neon:

parameters:
	debugMode: %debugMode%  # or specific IP addresses

3. Features

Directory Browser

• Navigate through your log directory structure
• Search for files and folders by name
• Pagination for directories with many files (100 items per page)
• Sort by type (directories first) and name

File Viewer

• View text log files with syntax highlighting
• View HTML Tracy dumps in iframe
• Pagination for large files (100KB chunks)
• Search within files with configurable context (3-300 lines)
• Download any log file

Configuration

Custom Log Directory

By default, the log viewer uses Tracy\Debugger::$logDirectory. If you need a custom log directory, extend the presenter and override the log directory in startup():

namespace App\Web;

use LogViewer\LogViewerPresenter as BaseLogViewerPresenter;

class LogViewerPresenter extends BaseLogViewerPresenter
{
	protected function startup(): void
	{
		parent::startup();

		// Option 1: Use hardcoded path
		$this->logDir = '/custom/path/to/logs';

		// Option 2: Use container parameters (recommended)
		$this->logDir = $this->container->getParameters()['tempDir'] . '/log';
	}
}

Then register your extended presenter in router configuration instead of the base one.

Access Control

The package automatically restricts access to debug mode only. For additional security, you can extend the presenter and add custom access control:

namespace App\Web;

use LogViewer\LogViewerPresenter as BaseLogViewerPresenter;
use Nette\Application\ForbiddenRequestException;

class LogViewerPresenter extends BaseLogViewerPresenter
{
	protected function startup(): void
	{
		parent::startup();

		// Add custom access control (e.g., admin role required)
		if (!$this->getUser()->isInRole('admin')) {
			throw new ForbiddenRequestException();
		}
	}
}
