Semantic Versioning
Semantic versioning is just like a set of rules and instructions that elaborate on the typical changes that rises the number of versions or possible each of the three numbers representing the version. 1
The extraction of frontend Laravel/UI
Laravel UI is an authorized package of Laravel 6.0 that includes the extracted UI parts from a Laravel project.
composer require laravel/ui "^1.0" --dev
php artisan ui vue --auth
Improved authorization responses:
In Laravel 6, this is now much easier using authorization response messages and the new Gate::inspect method. 2
Before
/**
* Determine if the user can view the given flight.
*
* @param \App\User $user
* @param \App\Flight $flight
* @return mixed
*/
public function view(User $user, Flight $flight)
{
return $this->deny('Explanation of denial.');
}
After
$response = Gate::inspect('view', $flight);
if ($response->allowed()) {
// User is authorized to view the flight...
}
if ($response->denied()) {
echo $response->message();
}
Lazy Collections
use App\LogEntry;
use Illuminate\Support\LazyCollection;
LazyCollection::make(function () {
$handle = fopen('log.txt', 'r');
while (($line = fgets($handle)) !== false) {
yield $line;
}
})
->chunk(4)
->map(function ($lines) {
return LogEntry::fromLines($lines);
})
->each(function (LogEntry $logEntry) {
// Process the log entry...
});
Job Middleware and Laravel Spark
namespace App\Jobs\Middleware;
use Illuminate\Support\Facades\Redis;
class RateLimited
{
/**
* Process the queued job.
*
* @param mixed $job
* @param callable $next
* @return mixed
*/
public function handle($job, $next)
{
Redis::throttle('key')
->block(0)->allow(1)->every(5)
->then(function () use ($job, $next) {
// Lock obtained...
$next($job);
}, function () use ($job) {
// Could not obtain lock...
$job->release(5);
});
}
}
Eloquent Subquery Enhancements
return Destination::addSelect(['last_flight' => Flight::select('name')
->whereColumn('destination_id', 'destinations.id')
->orderBy('arrived_at', 'desc')
->limit(1)
])->get();
return Destination::orderByDesc(
Flight::select('arrived_at')
->whereColumn('destination_id', 'destinations.id')
->orderBy('arrived_at', 'desc')
->limit(1)
)->get();
