Generate realistic PHP Composer install and update logs. Simulate dependency resolution, package downloads, and autoloader generation for Laravel and PHP project demos.
Press Ctrl + C to exit. Output is simulated for demo purposes only.
This module simulates package installs, dependency resolve, and lock files log events with realistic pacing.
It is designed for demos, log pipeline testing, and documentation where the real stack is unavailable.
All output is generated locally in the browser and is safe to run.
Loading composer repositories with package information Updating dependencies (including require-dev) - Installing monolog/monolog (2.3.4): Loading from cache - Installing guzzlehttp/guzzle (7.8.1): Loading from cache Writing lock file Generating autoload files
No. It is a simulator that prints log text only.
Yes. The CLI supports speed and repeat options, and the web page can be refreshed.
No. It does not install, update, or modify anything.
Composer is the dependency manager for PHP. It resolves packages, downloads them, and generates the autoloader. Install and update output is familiar to PHP developers.
Here we simulate that output for demos, CI log testing, or documentation without running composer install.
Popular questions and answers from Stack Overflow related to Composer.
composer install reads composer.lock and installs exact versions listed. composer update ignores the lock file, resolves dependencies fresh, and updates composer.lock. Use install for consistent deployments.
Check for conflicting version constraints, try composer update --with-dependencies, use composer why package to see why it is required, or add conflict resolution in composer.json.
Run: composer require vendor/package:1.2.3. Or in composer.json: "vendor/package": "1.2.3". Use ^ for compatible updates (^1.2), ~ for minor updates (~1.2), or exact version.
require lists packages needed to run the application. require-dev lists packages for development only (tests, debugging tools). Install without dev packages: composer install --no-dev.
Run: composer clear-cache or composer clearcache. Cache location: ~/.composer/cache/ or ~/.cache/composer/. Sometimes needed when packages fail to download or update properly.
In composer.json, add autoload section: {"psr-4": {"App\\": "src/"}}. Run composer dump-autoload. Include vendor/autoload.php in your code. Supports PSR-4, PSR-0, classmap, files.
Download installer: curl -sS https://getcomposer.org/installer | php. Move to path: mv composer.phar /usr/local/bin/composer. Verify: composer --version. Update: composer self-update.
Regenerates autoload files (vendor/autoload.php and autoload_*.php). Use after: adding new classes, changing autoload config, or optimizing. Add -o flag for optimized class map.
Add repository in composer.json: {"type": "vcs", "url": "git@github.com:user/repo.git"}. Configure SSH keys or use auth.json for credentials. For GitLab/GitHub tokens, use composer config.
Run: composer require vendor/package:1.0.0 (specific version). Or edit composer.json to constrain version, then composer update vendor/package. Check available versions: composer show vendor/package --all.
