Nano Auth

Nano Auth is a library that allows you to create authentication for your apps.

Requirements

Strictly requires PHP 7.4.

Install

Via Composer

$ composer require midorikocak/nanoauth

Usage

Authentication

The Authentication class has 4 public methods that you can use:

<?php

declare(strict_types=1);

namespace midorikocak\nanoauth;

interface AuthenticationInterface
{
    public function login(string $username, string $password): bool;

    public function logout(): void;

    public function isLogged(): bool;

    public function getLoggedUser();
}

To use it you should supply with a user repository.

$db = new Database(new PDO('sqlite::memory:'));
$userRepository = new UserRepository($db);
$auth = new Authentication($userRepository);

User implements UserInterface

A user object that we can authenticate should implemennt UserInterface.

<?php

declare(strict_types=1);

namespace midorikocak\nanoauth;

interface UserInterface
{
    public function __construct(?string $id, string $username, string $email, string $password);

    public function getPassword(): string;

    public function getUsername(): string;

    public function getEmail(): string;

    public function getId(): ?string;

    public function setId(string $id): void;
}

UserRepository

To interact with user data, we need to supply user repository to our authentication object. If you want to use your own implementation of user repository, you can implement your own UserInnterface. Here repository constructor expects a NanoDB object.

$userRepository = new UserRepository($db);
$auth = new Authentication($userRepository);

Authorization

To add authentication and authorization capabilities, you can use AuthorizationTrait in your App classes.

Let's say we created our app in this way:

<?php

declare(strict_types=1);

use midorikocak\nanodb\Database;
use midorikocak\nanoauth\UserRepository;
use midorikocak\nanoauth\Authentication;

$db = new Database(new PDO('sqlite::memory:'));

$userRepository = new UserRepository($db);

$auth = new Authentication($userRepository);
$entryRepository = new Journal($db);
$app = new App($entryRepository);

$this->app->setAuthentication($this->auth);

To check login we should trigger checkLogin() method in our public methods.

<?php 

declare(strict_types=1);

use midorikocak\nanodb\Database;
use midorikocak\nanoauth\UserRepository;
use midorikocak\nanoauth\Authentication;
use midorikocak\nanoauth\AuthorizationTrait;

 class App
{
    use AuthorizationTrait;

    private Journal $journal;

    public function __construct(Journal $journal)
    {
        $this->journal = $journal;
    }

    public function addEntry(string $content)
    {
        $this->checkLogin();

        $entry = new Entry($content);
        $this->journal->save($entry);
    }
}

Motivation

Mostly educational purposes.
