## At a glance

- **Vendor**: yireo (https://packagento.com/yireo.md)
- **Latest version**: 1.4.25 — released 2026-05-19
- **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/yireo/magento2-linkpreload 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 yireo/magento2-linkpreload:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## What it does

Magento 2 extension to set HTTP Link headers for primary resources to allow for HTTP/2 preloading

## README

Magento 2 extension to set HTTP Link headers for primary resources to allow for HTTP/2 preloading.

Note: This module was formally known as `Yireo_ServerPush` but the name gave a wrong impression (referring to the HTTP/2 `PUSH` feature). Hence this module was renamed.

## Dependencies

### Require

| Package | Constraint |
|---|---|
| ext-pcre | * |
| magento/framework | ^102.0\|^103.0 |
| magento/module-backend | ^101.0\|^102.0 |

## Quality

Latest release (1.4.25) 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 | 12 | 12 warnings (ruleset: Magento2) — 8 auto-fixable with phpcbf |
| PHPMD | Warning | 3 | 3 rule violations (UnusedFormalParameter:3) |
| Cpd | Pass | 0 |  |
| 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 | 4 | 4 | – | – |
| 2.4.8 | – | 4 | 4 | – |
| 2.4.9 | – | – | 4 | 4 |


### 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 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | Pass | Pass |


### 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=["yireo/magento2-linkpreload"],
  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.
