README

Integrates the firebase/php-jwt library with phpnomad/auth's JwtStrategy interface. It provides a single concrete strategy that encodes payloads into HS256-signed JSON Web Tokens and decodes them back into arrays, translating firebase/php-jwt's exception types into PHPNomad\Auth\Exceptions\JwtException so the rest of your application only has to catch one thing.

Installation

composer require phpnomad/firebase-jwt-integration

What This Provides

A FirebaseJwt strategy class that implements PHPNomad\Auth\Interfaces\JwtStrategy using firebase/php-jwt, with HS256 for both encoding and verification.
Exception translation that maps ExpiredException, SignatureInvalidException, BeforeValidException, and the standard PHP value errors into PHPNomad\Auth\Exceptions\JwtException with descriptive messages.

Requirements

phpnomad/auth ^1.0 for the JwtStrategy interface and its JwtException type.
firebase/php-jwt ^6.10 as the underlying JWT library.

Usage

Bind FirebaseJwt to the JwtStrategy interface inside one of your bootstrapper initializers. Any service that depends on JwtStrategy will then receive this implementation without knowing which library is wired in behind it.

<?php

namespace MyApp\Strategies;

use PHPNomad\Auth\Interfaces\JwtStrategy;
use PHPNomad\JWT\Firebase\Integration\Strategies\FirebaseJwt;
use PHPNomad\Loader\Interfaces\HasClassDefinitions;

final class JwtInitializer implements HasClassDefinitions
{
    public function getClassDefinitions(): array
    {
        return [
            FirebaseJwt::class => JwtStrategy::class,
        ];
    }
}

With that binding in place, a service can take JwtStrategy as a constructor dependency and call $jwt->encode($payload, $secret) or $jwt->decode($token, $secret) without ever referencing FirebaseJwt directly.
