Installation

Prerequisites

Nexus repository access credentials (username and password) — contact sales@tuxcare.com
To browse available artifacts, visit TuxCare Nexus and click Sign in in the top right corner. You may need to refresh the page after logging in.

Locate the auth.json file
Composer reads credentials from a per-user auth.json. Create or edit the file at:
- Linux/macOS:
```
~/.composer/auth.json
```
- Windows:
```
%APPDATA%\Composer\auth.json
```
Add your TuxCare credentials
Use either the Composer CLI or edit auth.json directly to add credentials for nexus.repo.tuxcare.com:
```
composer config --global --auth http-basic.nexus.repo.tuxcare.com USERNAME PASSWORD
```
Replace USERNAME and PASSWORD with the credentials provided by TuxCare.

Add the els_php Composer repository either via CLI or by editing composer.json:

composer config repositories.tuxcare '{"type":"composer","url":"https://nexus.repo.tuxcare.com/repository/els_php/","options":{"http":{"verify":true}}}' --json

Install Firebase PHP-JWT
Install the TuxCare-maintained Firebase PHP-JWT release that matches your project:
```
composer require firebase/php-jwt:6.11.1-p2+tuxcare
```
Check the exact version listed in your TuxCare Nexus account to ensure you receive the most recent patched release.
If you edited composer.json manually, run composer update to install the package:
```
composer update
```
Composer will resolve dependencies against the TuxCare repository and install the patched releases.

Composer Repository Configuration

If you encounter dependency resolution errors like:

packages from higher priority repository do not match your constraint

it usually means your project requires a package version that is not yet available in the TuxCare repository.

Solution: Update your composer.json to set the TuxCare repository as non-canonical:

{
    "repositories": [
        {
            "type": "composer",
            "url": "https://nexus.repo.tuxcare.com/repository/els_php/",
            "canonical": false
        }
    ]
}

This allows Composer to fall back to Packagist for packages not available in the TuxCare repository, while still preferring TuxCare patches when available.
