Canonical URL: https://packagento.com/swissup/module-diagnostic

## At a glance

- **Vendor**: swissup (https://packagento.com/swissup.md)
- **Latest version**: 1.0.12 — released 2026-05-15
- **Pricing**: Free
- **Package type**: Magento 2 module
- **Status**: active, accepting new buyers

## Installation

Packagento is licence-gated, so even free packages need a licence on a project before Composer can resolve them.

1. **Sign in or create an account** at https://packagento.com/customer/account/.

2. **Add the package to your account.** Open https://packagento.com/swissup/module-diagnostic and complete the free checkout. A licence is minted automatically.

3. **Create or pick a project, then activate the licence on it.**
   - Projects represent the Magento installs you deploy to. Manage them at https://packagento.com/projects/.
   - Activate the new licence on the project you'll deploy this package to. Activation is what generates the Composer credentials scoped to that project.

4. **Add the project credentials to your Magento codebase.**

   Grab the project's public + private key from https://packagento.com/projects/ (open the project, then its Credentials tab), and add them to `auth.json`:

   ```json
   {
     "http-basic": {
       "packagento.com": {
         "username": "ppk_live_...",
         "password": "psk_live_..."
       }
     }
   }
   ```

   Add the Packagento Composer repository to `composer.json`:

   ```json
   {
     "repositories": [
       { "type": "composer", "url": "https://packagento.com" }
     ]
   }
   ```

5. **Install and apply.**

   ```bash
   composer require swissup/module-diagnostic:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## What it does

Swissup Diagnostic Module

## README

The Swissup Diagnostic module is a tool designed for Magento 2 store owners and developers to gather essential information about their Magento environment. This command-line utility provides an overview of the PHP, Magento, and server-related details.

### Key Features:

- **Environment Information:** Details such as PHP version, Magento version, Composer version, and server user information.
  
- **Folder Structure Check:** Verify if any default Magento and Swissup modules/themes were not overwritten.

- **Magento 2 Theme Data:** Display a table of Magento 2 themes to check if no **virtual** themes exist.

- **Fixing the virtual themes**

- **Assets Optimization Manager:** Enable/disable JS and CSS merge and minification settings.

- **Module Management:** Disable/enable all Swissup modules or 3rd-party modules while preserving their original state.

### Usage:

Execute the following commands to use the diagnostic tools:

```bash
## Display environment and system information
bin/magento swissup:info

## Fix virtual themes
bin/magento swissup:info:virtualfix

## Manage JS/CSS optimization settings
bin/magento swissup:info:assets

## Enable all optimizations (merge and minify JS/CSS/HTML)
bin/magento swissup:info:assets --enable-all

## Disable all optimizations
bin/magento swissup:info:assets --disable-all

## Enable specific settings
bin/magento swissup:info:assets --merge-css=1 --minify-css=1
bin/magento swissup:info:assets --merge-js=1 --minify-js=1
bin/magento swissup:info:assets --bundle-js=1 --minify-html=1

## Disable specific settings
bin/magento swissup:info:assets --merge-css=0 --minify-js=0

## Disable all currently enabled Swissup modules (saves state for later restoration)
bin/magento swissup:info:disable-swissup

## Enable previously disabled Swissup modules (restores original state)
bin/magento swissup:info:enable-swissup

## Disable all currently enabled 3rd-party modules, except Magento_ and Swissup_ (saves state for later restoration)
bin/magento swissup:info:disable-thirdparty

## Enable previously disabled 3rd-party modules (restores original state)
bin/magento swissup:info:enable-thirdparty
```

### Installation

#### For clients

There are several ways to install extension for clients:

 1. If you've bought the product at Magento's Marketplace - use
    [Marketplace installation instructions](https://docs.magento.com/marketplace/user_guide/buyers/install-extension.html)
 2. Otherwise, you have two options:
    - Install the sources directly from [our repository](https://docs.swissuplabs.com/m2/extensions/diagnostic/installation/composer/) - **recommended**
    - Download archive and use [manual installation](https://docs.swissuplabs.com/m2/extensions/diagnostic/installation/manual/)

#### For developers

Use this approach if you have access to our private repositories!

```bash
composer config repositories.swissup composer https://docs.swissuplabs.com/packages/
composer require swissup/module-diagnostic:dev-master --prefer-source
bin/magento setup:upgrade
```

## Quality

Latest release (1.0.12) fails the Packagento QA pipeline. Verdicts below are per-cell (Magento line × PHP version) for the matrixed tools, and run-once for the static / security tiers.


### Compatibility

Each Magento line is installed on its supported PHP versions, then the module is built (DI compile + static-content deploy). Cells show passed / failed / untested; staircase gaps render as `–`.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | Pass | Pass |


### Code Quality

Advisory checks against the module's source. Never affect the Compatibility verdict — a phpcs finding can't make a module incompatible.

#### Static Analysis

Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Warning | 102 | 102 warnings (ruleset: Magento2) — 5 auto-fixable with phpcbf |
| PHPMD | Warning | 14 | 14 rule violations (MissingImport:10, UnusedFormalParameter:3, UnusedLocalVariable:1) |
| Cpd | Warning | 3 | 3 duplicated chunks spanning 190 total lines (min-lines=5, min-tokens=70) |
| Composer validate | Info | 1 | valid; 1 advisory note (composer validate --strict) |

#### PHPStan

Type-checks the module against a real Magento install. Re-runs per Magento + PHP version because resolvable symbols differ between releases.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | 8 | 8 | – | – |
| 2.4.8 | – | 8 | 8 | – |
| 2.4.9 | – | – | 8 | 8 |


### Tests

Unit and integration suites run per Magento + PHP cell. Test failures speak to the module's behaviour, not its compatibility with a line, so they're reported here separately.

#### Unit Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |

#### Integration Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |


### Security

Dependency-advisory audit (composer audit) plus a source malware scan. A malware detection fails the version outright.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| Composer audit | Pass | 0 |  |
| Malware scan | Pass | 0 |  |

## Licence and pricing

Free. A licence is still minted on checkout and bound to your project for Composer access — no payment step.

Refundable within 14 days of first purchase via https://packagento.com/account/refunds/.

## Install via Claude Code or any MCP client

The Packagento MCP server can run the licence + project + Composer steps above in one tool call:

```
purchase_and_install_packages(
  composer_names=["swissup/module-diagnostic"],
  project_id="proj_xxx"
)
```

This handles cart, checkout, licence minting, project activation, and writes auth.json credentials. Connect a client with `claude mcp add packagento https://mcp.packagento.com`. Full setup at https://packagento.com/docs/mcp-setup.
