Quickstart Guide
Install via Composer:
composer require --dev vimeo/psalm
Add a config:
./vendor/bin/psalm --init
Then run Psalm:
./vendor/bin/psalm
The config created above will show you all issues in your code, but will emit INFO issues (as opposed to ERROR) for certain common trivial code problems. If you want a more lenient config you can specify the level with
./vendor/bin/psalm --init [source_dir] [level]
You can also learn how to suppress certain issues.
