`composer require etechflow/module-canonical-hreflang`

Canonical URL: https://packagento.com/etechflow/module-canonical-hreflang

## At a glance

- **Vendor**: etechflow (https://packagento.com/etechflow.md)
- **Latest version**: 1.1.1 — released 2026-06-22
- **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/etechflow/module-canonical-hreflang 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 etechflow/module-canonical-hreflang:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## README

**Canonical URLs + hreflang tags** for Magento 2 — de-duplicates the URL variants that leak SEO equity and serves the right store view per locale. Part of the **Etechflow SEO Suite**.

### Why

Magento generates the same content under many URLs — a product reachable under several category paths, category pages with `?colour=red&price=10-20`, `?p=2` pagination, and tracking-param variants. Without a clean canonical, Google splits ranking signals across all of them. This module emits one authoritative canonical per page, and for multi-store catalogues, hreflang links so each locale's customers land on the right store view.

### Features

**Canonical**
- Product / category / CMS pages (each toggleable).
- **Category-free product canonical** — a product in 5 categories still has one canonical.
- **Strips query parameters** — `?filter`, `?sort`, `?utm_*` all canonicalise to the clean URL.
- **Pagination control** — self-referencing (`?p=2` canonicalises to itself, Google-recommended) or consolidate-to-page-1.
- **De-dupes** — removes any existing canonical (e.g. Magento core's) so you never emit two.

**Hreflang**
- `rel="alternate"` links across every active store view.
- Each store's code auto-derived from its **Locale** (`en_GB` → `en-gb`), or overridden per store (`1:en-gb`).
- Optional `x-default`.

### How it works

A single plugin on `Magento\Framework\View\Result\Page::renderResult` resolves the current entity and adds the `<link>` tags via **PageConfig remote assets** — so they render in any theme, including Hyvä, with no template changes. `Service\CanonicalResolver` and `Service\HreflangResolver` compute the URLs.

### Install

```bash
composer require etechflow/module-canonical-hreflang
bin/magento module:enable Etechflow_CanonicalHreflang
bin/magento setup:upgrade
bin/magento setup:di:compile     # production
```

### Configure

**Stores → Configuration → Etechflow → Canonical & Hreflang**: master *Enable*, then the canonical toggles (product/category/CMS, strip-query, pagination mode) and hreflang (enable, x-default store, per-store overrides).

> Tip: turn off Magento's own canonical (Catalog → Catalog → Search Engine Optimization) — this module dedupes it anyway, but disabling avoids the wasted work.

| magento/module-cms | >=104.0 |

## Quality

Latest release (1.1.1) 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 | not tested |


### 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 | Fail | 56 | 4 errors, 52 warnings (ruleset: Magento2) — 3 auto-fixable with phpcbf |
| PHPMD | Warning | 11 | 11 rule violations (CyclomaticComplexity:4, NPathComplexity:4, UnusedFormalParameter:2, ExcessiveClassComplexity:1) |
| Cpd | Pass | 0 |  |
| Composer validate | Info | 5 | valid; 5 advisory notes (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 | 9 | 9 | – | – |
| 2.4.8 | – | 9 | 9 | – |
| 2.4.9 | – | – | 9 | N/A |


### 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=["etechflow/module-canonical-hreflang"],
  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.
