Informations about the package laravel-preflight
Laravel Preflight
The fastest way to find every breaking change before you upgrade Laravel.
One Artisan command scans your entire codebase and reports only the upgrade issues that actually exist in your project — across PHP files, composer.json, config files, and .env. Supports upgrading from Laravel 8 through 13 with 70+ checks covering every major breaking change.
Why Laravel Preflight?
The official Laravel upgrade guide lists every possible breaking change — but most of them won't affect your app. Reading through the full guide, manually searching your code, and checking config keys wastes hours.
This tool does it in seconds:
- Zero false positives — only flags issues found in your actual code
- Multi-version support — checking Laravel 8 → 13 covers all 5 intermediate upgrade paths in one run
- Actionable fixes — every issue includes the exact fix command or change needed
- No code modifications — read-only scan, safe to run any time
- CI/CD ready — exits with code
1when blocking issues exist,0when clean
Installation
Auto-discovered. No service provider registration needed.
Quick Start
The command auto-detects your current Laravel version from composer.json. Multi-version upgrades are fully supported — scanning from Laravel 8 to 13 covers all intermediate breaking changes in a single run.

How It Works
1. Detect — Reads your composer.json to determine the current Laravel version and the target you specify.
2. Scan — Runs four analyzers across your codebase:
| Analyzer | Scans | Checks |
|---|---|---|
| ComposerAnalyzer | composer.json |
Deprecated, removed, or replaced packages |
| CodeAnalyzer | app/, routes/, config/, database/, resources/, tests/ |
Regex pattern search across all .php files |
| ConfigAnalyzer | config/*.php |
Missing or renamed config keys |
| EnvAnalyzer | .env.example / .env |
New required environment variables |
3. Report — Prints a grouped, colour-coded console report. Use --report to also write storage/upgrade-report.md and storage/upgrade-report.html.
Supported Upgrade Paths
| Target | From | Key Breaking Changes Checked |
|---|---|---|
| Laravel 9 | Laravel 8 | PHP 8.0 required, SwiftMailer removed, fruitcake/laravel-cors deprecated, facade/ignition replaced, $dates property deprecated, Flysystem 3.x, dispatch_now() removed, mail config default key |
| Laravel 10 | Laravel 9 | PHP 8.1 required, Bus::dispatchNow() removed, assertDeleted() removed, $dates fully removed, Predis 2.x required, native return types enforced, getQueueableRelations() return type |
| Laravel 11 | Laravel 10 | PHP 8.2 required, slim skeleton (Http/Kernel.php removed, Console/Kernel.php removed), service providers consolidated, routes/api.php not auto-loaded, routes/channels.php not auto-loaded, Carbon 3.x |
| Laravel 12 | Laravel 11 | doctrine/dbal dropped, Model::reguard() removed, Response::json() throws on invalid JSON, Collection::groupBy() key preservation, whereRelation() signature, Str::password() removed, spatie/laravel-ignition ^2.0 |
| Laravel 13 | Laravel 12 | VerifyCsrfToken → PreventRequestForgery, cache serializable_classes, DB::upsert() validation, cache key prefix format, polymorphic pivot names, JobAttempted event property, array_first()/array_last() conflicts |
Example Output
Report Files
Add --report to generate both a Markdown and a self-contained HTML report:
| File | Description |
|---|---|
storage/upgrade-report.md |
Markdown — commit to your repo or share in a PR |
storage/upgrade-report.html |
Interactive HTML — severity filters, collapsible cards, one-click copy for fix commands, animated readiness score |
Severity Levels
| Level | Meaning |
|---|---|
CRITICAL |
Will break your application — must fix before upgrading |
WARNING |
Likely to cause bugs or unexpected behaviour — review required |
INFO |
Behavioural change to be aware of — may or may not affect your app |
CI / CD Integration
The command exits with code 1 when any issues are detected, and 0 when the codebase is clean — making it easy to gate deployments or upgrade PRs in any CI pipeline.
Extending: Adding a New Laravel Version
- Create
src/VersionRegistry/Laravel{N}Upgrade.phpextendingBaseUpgrade - Implement
getBreakingChanges()returning an array ofBreakingChangeobjects - Register it in
VersionRegistry::$upgradesand bump$latestVersion
Each breaking change supports four detection strategies:
| Property | Detected By | Example |
|---|---|---|
$searchPattern |
CodeAnalyzer — regex over PHP files |
'/VerifyCsrfToken/' |
$composerPackage |
ComposerAnalyzer — checks composer.json |
'facade/ignition' |
$configKey |
ConfigAnalyzer — checks config/{file}.php |
'cache.serializable_classes' |
$envKey |
EnvAnalyzer — checks .env.example |
'CACHE_PREFIX' |
Architecture
Requirements
| Version | |
|---|---|
| PHP | ^7.4 | ^8.0 |
| Laravel | ^8.0 through ^13.0 |
FAQ
Does it modify any files? No. The scan is entirely read-only. Nothing in your project is changed.
Can I run it on a project that is already on a newer version? Yes — the command detects your current version and skips checks that don't apply. If you're already on the target version it exits immediately.
How is it different from Rector or Laravel Shift? Rector and Shift modify your code. This tool only reports — it tells you what needs to change and where, so you can make the changes yourself with full control.
Can I use it in a pre-upgrade CI check?
Yes. It returns exit code 1 when issues are found. Add it to your CI pipeline to block merges until the codebase is compatible with the target version.
What if a check fires but doesn't apply to my app? The results are informational. Review the listed file paths and decide whether the fix applies to your specific usage.
