Utopia Logger library is simple and lite library for logging information, such as errors or warnings. This library aims to be as simple and easy to learn and use as possible. This library is maintained by the Appwrite team.

Although the library was built for the Utopia Framework project, it is completely independent, dependency-free and can be used with any other PHP project or framework.

Getting Started

Install using composer:

composer require utopia-php/logger

require_once '../vendor/autoload.php';

use Utopia\Logger\Adapter\AppSignal;
use Utopia\Logger\Adapter\Raygun;
use Utopia\Logger\Adapter\Sentry;
use Utopia\Logger\Adapter\LogOwl;
use Utopia\Logger\Log;
use Utopia\Logger\Log\Breadcrumb;
use Utopia\Logger\Log\User;
use Utopia\Logger\Logger;

// Prepare log
$log = new Log();
$log->setMessage("Document efgh5678 not found");
$log->setUser(new User("efgh5678"));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_DEBUG, "http", "DELETE /api/v1/database/abcd1234/efgh5678", \microtime(true) - 500));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_DEBUG, "auth", "Using API key", \microtime(true) - 400));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_INFO, "auth", "Authenticated with * Using API Key", \microtime(true) - 350));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_INFO, "database", "Found collection abcd1234", \microtime(true) - 300));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_DEBUG, "database", "Permission for collection abcd1234 met", \microtime(true) - 200));
$log->addBreadcrumb(new Breadcrumb(Log::TYPE_ERROR, "database", "Missing document when searching by ID!", \microtime(true)));
$log->addTag('sdk', 'Flutter');
$log->addTag('sdkVersion', '0.0.1');
$log->addTag('authMode', 'default');
$log->addTag('authMethod', 'cookie');
$log->addTag('authProvider', 'MagicLink');
$log->addExtra('urgent', false);
$log->addExtra('isExpected', true);

// Sentry
$adapter = new Sentry("[YOUR_SENTRY_DSN]");
$logger = new Logger($adapter);

// AppSignal
$adapter = new AppSignal("[YOUR_APPSIGNAL_KEY]");
$logger = new Logger($adapter);

// Raygun
$adapter = new Raygun("[YOUR_RAYGUN_KEY]");
$logger = new Logger($adapter);

// Log Owl
$adapter = new LogOwl("[YOUR_SERVICE_TICKET]");
$logger = new Logger($adapter);

If you need to install dependencies, run:

docker run --rm --interactive --tty \
  --volume $PWD:/app \
  composer update --ignore-platform-reqs --optimize-autoloader --no-plugins --no-scripts --prefer-dist

To run all unit tests, prepare the .env file using .env.example as a template. Then, run:

docker run --rm --interactive --tty --env-file .env \
  --volume $PWD:/app \
  composer test

Make sure to replace TEST_SENTRY_DSN with actual keys from Sentry.

Make sure to replace TEST_APPSIGNAL_KEY with key found in Appsignal -> Project -> App Settings -> Push & deploy -> Push Key

Make sure to replace TEST_RAYGUN_KEY with key found in Raygun -> Project -> Application Settings -> Api Key

To run static code analysis, use the following Psalm command:

docker run --rm --interactive --tty \
  --volume $PWD:/app \
  composer check

System Requirements

Utopia Framework requires PHP 8.0 or later. We recommend using the latest PHP version whenever possible.
