LiVue lets you write Vue 3 directives in Blade templates without APIs or .vue files, merging Livewire server-driven architecture with the Vue ecosystem.

Without s3:ListBucket in the IAM policy, S3 returns 403 for missing files, making [Flysystem](https://flysystem.thephpleague.com) throw UnableToCheckFileExisten

Laravel Vite defaults to localhost, breaking assets on custom domains. Set server.host and server.hmr.host in vite.config.js, or use valetTls for Valet HTTPS.

HTML assertions on complex views are brittle. Use viewData() to assert view variables directly, and compare Models by id or toArray() to avoid identity issues.

Fake $_SERVER in Laravel feature tests by passing server vars per-request, or use withServerVariables() to apply them globally for the entire test method.

POST requests only return a 302, hiding the final page. Use followingRedirects() to automatically follow redirects and assert on the destination page content.

SQLite throws "no such function" for MySQL-specific functions like FIELD. Use PDO sqliteCreateFunction in TestCase setUp to register them and make tests pass.

Jobs dispatched in a transaction re-query the DB via SerializesModels before commit, reading stale data. Use afterCommit() to delay dispatch until after commit.

Passing a Generator directly to LazyCollection causes iterator_to_array to expand it all at once. Wrap it in a Closure to restore true lazy evaluation.

Doctrine DBAL does not recognize MySQL enum type, causing migration failures. Covers Type::addType and registerDoctrineTypeMapping with when to use each fix.

Laravel Facade uses getFacadeAccessor to resolve instances from the Container. This post shows the difference between bind and singleton and how custom Facades

Mocking IteratorAggregate breaks foreach in PHPUnit. Return an ArrayObject from the mocked getIterator method to make foreach iterate over test data correctly.

Assertions inside a closure pass silently even if never called. Wrap the closure in Mockery::spy to verify invocation count and arguments in PHPUnit tests.

Save a model silently with saveQuietly, then selectively dispatch created or other Eloquent model events via a custom Builder macro fire method in Laravel.

PHP Curl throws a Comodo RSA SSL expired error on Linux due to missing Root CA. Use GuzzleHttp verify to point to the certificate file, globally or per service.

Laravel min/max rules compare string length by default, letting 0 pass validation. Add the numeric rule to switch to value comparison and fix the bug.

Avoid 3 migration rollback mistakes: mixing add/drop in one closure, dropping index and column together, and multiple dropColumn calls. Catch them with SQLite.

Load schema dump into SQLite in-memory database via PDO::exec, skipping per-file migrations. Cuts Laravel test time from 2:21 minutes down to 18 seconds.

MySQL's IF() fails on SQLite. Laravel 10's Expression interface generates Grammar-specific SQL, encapsulating cross-database differences into a reusable class.

When a third-party class needs constructor parameters, Laravel cannot auto-resolve it. Register it with bind in a ServiceProvider to enable type-hint injection.

Use Blade addExtension to make .md files support @include and variables, then pass the output through CommonMark to generate HTML for dynamic documentation.

Build an Alpine.js errors plugin that mirrors the Laravel MessageBag API, so 422 AJAX validation errors display just as easily as the @error directive.
