Phpstan Baseline Per Identifier Laravel Package

Technical Evaluation

Architecture fit: Excellent alignment with PHPStan's static analysis workflow. The package enhances baseline management by splitting monolithic files into per-identifier components without altering core PHPStan functionality, making it ideal for large codebases where single-file baselines become unwieldy.

Integration feasibility: High. Installation via Composer is trivial, and integration requires only minimal config changes (replacing single baseline include with loader reference). The CLI workflow (generate-baseline + split-phpstan-baseline) integrates seamlessly with existing CI/CD pipelines and Composer scripts.

Technical risk: Low-to-moderate. Primary risks include PHPStan version compatibility (requires ≥2.0), potential edge cases with complex regex patterns in error messages, and filesystem limits for extremely high identifier counts (though uncommon). The "0 dependents" metric suggests limited real-world adoption, but active GitHub maintenance (2.3.0 release) mitigates this.

Key questions:

• How does it handle identical error messages across different files?
• Are there performance implications when loading thousands of small baseline files?
• How does it interact with IDE plugins (e.g., PhpStorm PHPStan integration)?
• What happens during PHPStan upgrades that change error message formats?

Integration Approach

Stack fit: Native compatibility with Laravel's PHPStan setup (v9+). Works with both neon and PHP-based baselines, fitting standard Laravel project structures. The package requires no additional infrastructure beyond existing PHPStan usage.
