In order to ease development and collaboration, eQual organizes application logic into themed packages represented by folders, located under the /packages directory.

These packages contain several components : models, views, controllers, and translation files. Models define data structure, views describe user interface, controllers manage data flow, and translations support i18n features.

Package structure

Each package is defined as follows :

├── classes
│   └── */*.class.php
├── actions
│   └── */*.php
├── apps
│   └── */*.php
├── data
│   └── */*.php
├── tests
│   └── */*.php
├── init
│   ├── data
│   |   └── *.json
|   ├── test
│   |   └── *.json
│   ├── demo
│   |   └── *.json
│   ├── bin
│   |   └── *.*
│   ├── routes
│   |   └── *.json
│   └── assets
│       ├── css
│       ├── fonts
│       ├── img
│       |   └── brand
│       └── js
├── views
│   └── *
│       └── *.json
├── i18n
│   └── *
│       └── *.json
├── manifest.json         
├── config.json
Folder Role Example
classes model core\User.class.php, core\Group.class.php, core\Permission.class.php
actions action handler (controller) core_manage, core_utils
apps applications related to the package auth, apps
data data provider core_model_read, core_config_packages
tests test units default.php
init initialize the package (entities, data, routes) core_Group.json
views templates User.form.default.json, User.list.default.json
i18n translations User.json
assets static content (resources) js scripts, stylesheets, fonts, images

Self description (root)

A markdown file containing various relevant information about the package, its installation, configuration, and the features it offers.


Packages manifests are an essential tool for managing the packages ecosystem and ensure compatibility between different components and versions of software libraries, facilitating seamless integration and streamlined development processes.

Each package has a manifest file (manifest.json) containing information about the package along with the apps it provides and the dependencies it requires.

Property     Role Example
name (string) Name of the package, also used as an identifier.
It should match the name of the folder of the package.
version (string) The version of the package, ensuring accurate versionning. "2.0"
description (string) Short description of the package. "A short and yet explicit description of the package."
license (string) The license (and version) of the package. "LGPL-3"
authors (array <string>) List of the name(s) of the author(s). ["Cedric Francoys"]
tags (array <string>) List of descriptive tags or keywords associated with the package for easier categorization and searchability. ["Cedric Francoys"]
depends_on (array <string>) List of packages that need to be present and initialized in order for the package to work. []
requires (object) Map specifying external libraries or packages required by the package, along with version constraints using semantic versionning. "requires": {"swiftmailer/swiftmailer": "^6.2"}
config (object) Map associating config constants to the values specific to the package. "config": {"APP_LOGO_URL": "/assets/img/brand/logo.svg"}
apps (array <string | object>) Applications embedded in the package.
The list provides either Apps names (identifier) or descriptors for virtual apps to be used with the STD App (see below).
["apps", "auth", "app", "settings"]


    "name": "core",
    "description": "Foundation package holding common application logic and elementary entities.",
    "version": "2.0",
    "authors": ["Author Names"],
    "license": "License Type",
    "tags": [ "equal", "core" ],
    "depends_on": [],
    "requires": {
        "swiftmailer/swiftmailer": "^6.2",
        "phpoffice/phpspreadsheet": "^1.4",
        "dompdf/dompdf": "^0.8.3"
    "apps": [ "apps", "auth", "app", "settings", "workbench", "welcome" ]

apps property

The apps property might either contain strings or descriptor objects. The app application, defined in the core package, can act as surrogate for creating custom Apps using all standard features without having to write additional Angular components. In such case, the descriptor is expected to be a full descriptor of the app, similar to the ones used in the manifest of Apps.

Example of custom App definition
        "id": "inventory",
        "name": "Inventory",
        "extends": "app",
        "description": "Application inventory",
        "icon": "analytics",
        "color": "#6C3483",
        "text_color": "#050505",
        "access": {
            "groups": [
        "params": {
            "menus": {
                "left": "inventory.left",
                "top": ""

apps folder


Property Role Example
name The name of the application. Settings
description A short description of the role and usage of the application.
url Relative URL of the application. /settings
icon (optional) Identifier of the (material) icon for representing the application. settings
color (optional) Color used for the button (background-color). Defaults to #b0b0b0 #FF9741
text_color (optional) Color used for the text of the button (color). Defaults to #ffffff #000000
extends (optional) String telling which application it extends from, if any. app
access/groups List of groups the access to the application is restricted to. ['users']
params Object to be relayed to the targeted App targeted with extends(if supported). "params": { "menus" : { "left": "myApp.left" } }
params.menus The menu to be displayed for the App (possible menus are 'left' and 'right').
params.context The context to be used for the root URL ('/').
show_in_apps Flag telling if the application must be listed in the dashboard Apps list. default: false
tags (optional) List of labels for tagging of the application. ["equal", "core"]


The params property allows to provide the surrogate application (app) with parameters specific to the application being described. It can be used to define which menus must be loaded and which context must be displayed by default.


"params": {
    "menus": {
        "left": "settings.left",
        "top": ""
    "context": {
        "entity": "core\\User"
        "view": "list.default",
        "order": "id",
        "sort": "asc"
