@brainstack/auth

The Auth SDK is a powerful tool for managing user authentication in various applications. It provides a unified interface to interact with authentication methods, abstracting the underlying complexities and offering a streamlined API.

Description

Authentication is a crucial aspect of modern applications, often involving multiple providers and strategies. The Auth SDK simplifies this process by offering a consistent way to interact with various authentication methods. Whether you're dealing with email/password logins, social logins, or more advanced scenarios, the Auth SDK has you covered.

Installation

Install the Auth SDK using npm:

npm install @brainstack/auth

Usage

Creating an Auth Provider

To begin, create an instance of the Auth Provider by providing an integration that adheres to the AuthIntegration interface.

import { createAuthProvider } from '@brainstack/auth';

const integration = {
  // Implement the authentication methods here
};

const authProvider = createAuthProvider(integration);

Authentication Methods

The Auth SDK exposes a range of authentication methods, allowing you to interact with various aspects of the authentication process.

Sign In

Authenticate a user using their username and password.

const signInResult = await authProvider.signIn(username, password);
// Handle the result...

Sign Out

Sign a user out of the application.

const signOutResult = await authProvider.signOut();
// Handle the result...

Sign Up

Register a new user with a username, password, and email.

const signUpResult = await authProvider.signUp(username, password, email);
// Handle the result...

Lock Account

Lock a user's account to prevent further access.

const lockAccountResult = await authProvider.lockAccount(username);
// Handle the result...

Reset Password

Initiate a password reset for a user.

const resetPasswordResult = await authProvider.resetPassword(username);
// Handle the result...

Confirm Sign Up

Confirm a user's registration using a confirmation code.

const confirmSignUpResult = await authProvider.confirmSignUp(username, code);
// Handle the result...

Resend Sign Up Confirmation

Resend a confirmation code for user registration.

const resendSignUpResult = await authProvider.resendSignUp(username);
// Handle the result...

Forgot Password

Initiate a forgotten password recovery process.

const forgotPasswordResult = await authProvider.forgotPassword(username);
// Handle the result...

Forgot Password Confirmation Code

Submit a confirmation code to reset a forgotten password.

const forgotPasswordConfirmationResult = await authProvider.forgotPasswordConfirmationCode(username, code, newPassword);
// Handle the result...

Lock Session

Lock the user's session to enhance security.

const lockSessionResult = await authProvider.lockSession();
// Handle the result...

Unlock Session

Unlock the user's locked session.

const unlockSessionResult = await authProvider.unlockSession();
// Handle the result...

Unlock Account

Unlock a locked user account.

const unlockAccountResult = await authProvider.unlockAccount(username);
// Handle the result...

Disable Account

Disable a user's account.

const disableAccountResult = await authProvider.disableAccount(username);
// Handle the result...

Enable Account

Enable a disabled user account.

const enableAccountResult = await authProvider.enableAccount(username);
// Handle the result...

Refresh Token

Refresh the authentication token to extend the session.

const refreshTokenResult = await authProvider.refreshToken();
// Handle the result...

Check Permission

Check if the authenticated user has a specific permission.

const hasPermissionResult = await authProvider.hasPermission('permission');
// Handle the result...

Define Permission

Define a new permission for use in the system.

const definePermissionResult = await authProvider.definePermission('newPermission');
// Handle the result...

Validate Permission

Validate if a given permission is correctly defined.

const isValidPermission = authProvider.validatePermission('permission');
// Handle the result...

Define Role

Define a new role and associate it with a list of permissions.

const defineRoleResult = await authProvider.defineRole('newRole', ['permission1', 'permission2']);
// Handle the result...

Assign Role

Assign a role to a specific user.

const assignRoleResult = await authProvider.assignRole('username', 'role');
// Handle the result...

Check Role

Check if a user has a specific role.

const hasRoleResult = await authProvider.hasRole('username', 'role');
// Handle the result...

Add Custom Claim

Add custom claims to authentication tokens for application-specific needs.

authProvider.addCustomClaim('claimName', 'claimValue');
// Custom claim added...

Example

Imagine you're building a multi-platform application with different authentication providers. Here's how you could use the Auth SDK to streamline your authentication process:

import { createAuthProvider } from '@brainstack/auth';

// Implement the integration methods here
const integration = { /* ... */ };

const authProvider = createAuthProvider(integration);

// Sign in a user
const signInResult = await authProvider.signIn('user123', 'password123');
if (signInResult.success) {
  console.log('User signed in successfully');
} else {
  console.error('Sign-in failed');
}

Use Case

Consider a scenario where you're developing a cross-platform application that supports both email/password and social logins. The Auth SDK allows you to implement these authentication methods with ease, maintaining a consistent API across different providers.
