Requirements
Slim 4 requires PHP 7.2 or greater. The current Ubuntu LTS and Debian stable include 7.4, so this requirement is satisfied on up to date servers.
Installation
Core
composer require slim/slim:"4.*" composer require slim/psr7
Additional libraries
composer require filp/whoops composer require twig/twig composer require twig/intl-extra composer require slim/twig-view composer require doctrine/orm composer require vlucas/phpdotenv composer require php-di/php-di --with-all-dependencies composer require phpunit/phpunit --dev
Directories
mkdir public mkdir src mkdir templates mkdir tests
.gitignore
vendor/
composer.json autoloader
"autoload": {
"psr-4": {
"App\\": "src/"
}
},
"autoload-dev": {
"psr-4": {
"App\\Test\\": "tests/"
}
}
Run composer dump-autoload to generate the autoloader.
