FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package di
genai/di
Popular dependency-injection attributes and the processor that compiles them
into a genai/container definition file.
This is a build-time package (PHP 8): it's read by the genai/attribute
scanner during compilation. The container file it produces is PHP 5.3-safe,
like everything genai/container emits.
Attributes
| Attribute | Target | Effect |
|---|---|---|
#[Service] |
class | register the class as an autowired bean |
#[Repository] |
class | same — a stereotype for the persistence layer |
#[Configuration] |
class | register the class as a bean; its #[Bean] methods become factory beans |
#[Bean] |
method | a bean produced by calling the method on its (configuration) bean |
#[Value] |
parameter | inject a value into a constructor / factory parameter |
Service/Repository/Configuration all extend Component; one
ComponentProcessor handles them via ReflectionAttribute::IS_INSTANCEOF.
Usage
Point the scanner at your app plus this processor's namespace; it auto-registers
ComponentProcessor (by type) and dumps container.php:
#[Value] forms
${...} is resolved at compile time from the flat parameters map you pass to
Context (you populate it from your config source). A missing key fails the
build with a clear error.
#[Bean] id + the PHP 5.3 caveat
A #[Bean] method's id is, in order: the explicit #[Bean('id')] /
#[Bean(Type::class)], else the method's return type, else the method name.
A #[Bean] method is called at runtime (on the configuration bean). If your
runtime is PHP 5.3 it must not declare a : ReturnType (return types are
PHP 7+), so give the id explicitly:
On a PHP 7+/8 runtime you can use the return type and drop the explicit id.
Requires
php >=8.0, genai/attribute, genai/container (it bridges the two; the
runtime container it feeds stays PHP 5.3).
