A Psalm plugin for Laravel

Psalm plugin for Laravel

The package is seeking maintainers

⚠️ This is a perfect opportunity to learn Laravel very deep and collaborate with other high-skilled developers. At this moment, the package is maintained almost solely by @alies-dev, and he is looking for developers to build a team who can constantly improve this package and the whole Psalm ecosystem.

Some ideas to implement:

• Fully support custom Model Query Builders (medium)
• Add an option to rely on Model @property declarations only
• Get rid of barryvdh/laravel-ide-helper dependency and be more accurate with attribute types
• Support .sql files for migrations (to find information about attributes and their types)

Overview

This Psalm plugin brings static analysis and type support to projects using Laravel. Our goal is to find as many type-related bugs as possible, therefore increasing developer productivity and application health. Find bugs without the overhead of writing tests!

Quickstart

Step 1: Install

composer require --dev psalm/plugin-laravel

Step 2: Configure

If you didn't use Psalm on the project before, you need to create a Psalm config:

./vendor/bin/psalm --init

Step 3: enable the plugin:

./vendor/bin/psalm-plugin enable psalm/plugin-laravel

Step 4: Run 🚀

Run your usual Psalm command:

./vendor/bin/psalm

You can customize Psalm configuration using XML config and/or cli parameters.

Recommendation: use baseline file and increase errorLevel at least to 4: this way you can catch more issues. Step by step set errorLevel to 1 and use Psalm and this plugin at full power 🚀.

How it works

Under the hood it just runs https://github.com/barryvdh/laravel-ide-helper and feeds the resultant stubs into Psalm, which can read PhpStorm meta stubs.

It also parses any database migrations it can find to try to understand property types in your database models.

Psalm-Laravel-Plugin or Larastan?

Both! It's fine to use both tools at the same project: they use different approaches to analyze code, and thus you can find more bugs! Psalm and PHPStan use almost same the syntax annotations, so you should not have any conflicts.
