Module Structure

Basically HumHub modules are identical to Yii2 modules.

A very basic module consists of the following elements:

 controllers/ - contains controller classes
 migrations/  - contains database migration files and uninstall script
 models/      - contains model classes
 views/       - contains the modules view files
 widgets/     - contains widget classes
 Module.php   - the main module class which can contain enable/disable logic for contentcontainer etc.
 config.php   - base module configuration.
 module.json  - module metadata

Main Configuration File config.php

The config.php file enables automatic module loading and event configuration, without the need to manually modify the main application config. Module configuration files of enabled modules are processed by the humhub\components\bootstrap\ModuleAutoLoader within the bootstrap process of the application.

The config.php should contain the following attributes:

  • id - Unqiue ID of the module (required)
  • class - Namespaced classname of the module class (required)
  • namespace - The namespace of your module (required)
  • events - Array containing the modules event configuration (optional)
  • urlManagerRules - Array of URL Manager Rules (optional)
  • modules - Submodules (optional)



use johndoe\example\Module;
use humhub\widgets\TopMenu;

return [
    'id' => 'example',
    'class' => 'johndoe\example\Module',
    'namespace' => 'johndoe\example',
    'events' => [
        ['class' => TopMenu::class, 'event' => TopMenu::EVENT_INIT, 'callback' => ['johndoe\example\Events', 'onTopMenuInit']],

Note: Do not execute any code in the config.php since the result will be cached!

Base class Module.php

See chapter Base Class for an introduction of module base classes.

Meta data module.json

The module.json file holds basic meta data which is used for example by the marketplace.

Available attributes:

  • id - The module ID
  • version - The module version. This must follow the format of X.Y.Z. (Required)
  • name - The modules name
  • description - A short module description
  • humhub - HumHub requirements
    • minVersion - The minimum HumHub core version this module is compatible with.
    • maxVersion - The maximum HumHub core version this module is compatible with.
  • keywords - (Array) Some keywords
  • screenshots - (Array) Some screenshots for the marketplace, those should reside in the resourcesPath of your module.
  • homepage - An URL to the website of the module. (Optional)
  • authors - (Array) The authors of the module. (Optional)
    • name - The author's name.
    • email - The author's email address.
    • homepage - An URL to the author's website.
    • role - The author's role (e.g. developer or translator)

Example module.php file:

    "id": "example",
    "version": "1.0",
    "name": "My Example Module",
    "description": "My testing module.",
    "humhub": {
        "minVersion": "1.2",
		"maxVersion": "2.0"
    "keywords": ["my", "cool", "module"],
    "screenshots": ["assets/screen_1.jpg"],
	"homepage": "",
    "authors": [
            "name": "Tom Coder",
            "email": "",
            "role": "Developer"
            "name": "Sarah Mustermann",
            "email": "",
            "homepage": "",
            "role": "Translator"

Warning: You should align the minVersion of your module when using new features and test your modules on all supported versions.


The documentation files of the module must be located in the folder 'docs'.

The following table shows the default files.

File Required Description Yes A description and overview of the features No Information on how to use this module Yes A file which contains a curated, chronologically ordered list of changes for each version No Licencing information including the licence
