Sure! Here's a comprehensive documentation for the nanoweb-auth project:

nanoweb-auth

nanoweb-auth is a modular authentication library designed to provide a flexible and extensible authentication system. It supports multiple storage backends, such as file system, MariaDB, and Redis, and allows for easy integration into existing applications.

Features

• Modular design with support for different storage providers
• User management with login, password, and access control
• Token-based authentication with support for refreshing tokens
• Flexible access control system
• Extensible through custom storage providers

Installation

npm install nanoweb-auth

Usage

Setting up the Provider

First, set up the provider you want to use. nanoweb-auth comes with three built-in providers: FileSystemProvider, MariadbProvider, and RedisProvider.

FileSystemProvider

const { FileSystemProvider } = require('nanoweb-auth/providers');
const provider = new FileSystemProvider('/path/to/storage/directory');

MariadbProvider

const mariadb = require('mariadb');
const { MariadbProvider } = require('nanoweb-auth/providers');

const connection = await mariadb.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'password',
    database: 'auth_db'
});

const provider = new MariadbProvider(connection);

RedisProvider

const redis = require('redis');
const { RedisProvider } = require('nanoweb-auth/providers');

const client = redis.createClient();
await client.connect();
const provider = new RedisProvider(client);

Initializing the Manager

Create a new instance of the Manager class with the chosen provider.

const { Manager } = require('nanoweb-auth');
const manager = new Manager(provider);

User Management

Adding a User

const userData = {
    login: 'john_doe',
    name: 'John Doe',
    email: '[email protected]',
    password: 'securepassword',
    accessMap: { '*': 'r' } // Read-only access to all endpoints
};

const user = await manager.addUser(userData);
console.log('User added:', user);

Updating a User

const updatedUserData = {
    name: 'Johnathan Doe',
    email: '[email protected]',
    password: 'newsecurepassword',
    accessMap: { '*': 'rw' } // Read-write access to all endpoints
};

const updatedUser = await manager.updateUser('john_doe', updatedUserData);
console.log('User updated:', updatedUser);

Deleting a User

const success = await manager.deleteUser('john_doe');
console.log('User deleted:', success);

Token Management

Creating a Token

const user = await manager.loadUser('john_doe');
const token = manager.createToken(user);
console.log('Token created:', token);

Refreshing a Token

const refreshedToken = manager.refreshToken('existing_token_id');
console.log('Token refreshed:', refreshedToken);

Access Control

Checking User Access

const user = await manager.loadUser('john_doe');
const hasAccess = user.hasAccess('/some/protected/resource', 'r'); // Check for read access
console.log('User has access:', hasAccess);
