Service auto registration and configuration for Nette DI

Build Status Coverage Status

fmasa\autoDI is package intended to make registration and configuration of services easier.

Future of extension

In Nette 3.0, SearchExtension was introduced. It builds on the same concept as this extension (in which I stole the concept from Symfony DependencyInjection). Unfortunately there are still a few problems that need to be fixed in order to fully replace fmasa/auto-di (i.e. nette/di#215), but it's on the other hand part of Nette DI core and supports several features, that fmasa/auto-di doesn't (yet). These are ways to register services implementing specific interface or extending specific class.

So long-term goal is to deprecate this extension in favor of SearchExtension, when (and if) SearchExtension reaches feature parity. Until then I plan to maintain and improve this package since I use it myself in many projects.


The best way to install fmasa/auto-di is using Composer:

$ composer require fmasa/auto-di

To enable auto registration register extension in your config.neon:

    autoDI: Fmasa\AutoDI\DI\AutoDIExtension

Pattern based definition

autoDI registers services defined by regex:

        - class: App\Model\**\*Repository

This registers every class under namespace App\Model which name ends with Repository:

  • App\Model\Eshop\UserRepository
  • App\Model\CMS\Comments\CommentsRepository

There are several simple operators that can be used in patterns:

  • * matches class name, one namespace level or part of it (without \)
  • ** matches any part of namespace or classname (including \)
  • {Eshop,CMS} options list, any item of list matches this pattern

Apart from these, any PCRE regular expression can be used.

Classes and generated factories

Package supports both classes and generated factories.

Classes are matched agains class field, factories againts implement field, which corresponds to way Nette use these fields.

When using class field, all matching interfaces are skipped and vice versa.

        # Repositories
        - class: App\Model\**\*Repository 
        # Component factories
        - implement: App\Components\very**\I*Factory

Tags, autowiring, ...

Every option supported in DI (tags, inject, autowiring, ...) is supported with same syntax as normal service registration

        # Repositories
        - class: App\Model\Subscribers\**
          tags: [eventBus.subscriber]

The snippet above registers all classes in App\Model\Subscribers namespace with eventBus.subscriber tag.

Exclude services

Sometimes we wan't to exlude certain services from registration. For that we can use exclude field, that accepts pattern or list of patterns:

        - class: App\Model\**
          exclude: App\Model\{Entities,DTO}**

which is same as

        - class: App\Model\**
              - App\Model\Entities**
              - App\Model\DTO**

Already registered services

When extension founds service, that is already registered (by services section, different extension or previous autoDI definition), it's skipped.

This allows manual registration of specific services that need specific configuration.

Defaults section

To specify base configuration for all services registered via autoDI, defaults section can be used:

        tags: [ ]

        # these services will have tag
        - class: App\Model\Repositories\**
        # these services will have only tag eventBus.subscriber 
        - class: app\Model\Subscribers\**
          tags: [ eventBus.subscriber ]

Configuring directories

By default extension searches for services in %appDir%, but other directories can be specified:

        - %appDir%
        - %appDir%/../vendor

Register services on configuration

Compiler extensions such as AutoDIExtension manipulates the DI container in two phases (configuration loading and before compilation). By default this extension registers all services before compilation. This may not be optimal if you wan't to use this extension with other extensions such as decorator.

You can enforce registration in configuration phase by setting registerOnConfiguration option to true.

When no service is registered for configuration entry, either because no class/interface matches the pattern or all matched services were already registered in container, exception is thrown. This check can be disabled by setting errorOnNotMatchedDefinitions option to false.
