Using CouchDB for FrontEnd Authentication

Looking for guidance on the optimal strategy to create a web application using CouchDB, specifically one that requires front-end users to log in (such as a forum). I am in need of an authentication mechanism to verify username/password and save them in a session/cookie.

Is it possible to achieve this within CouchDB itself? Can server-side code be executed directly on CouchDB, or do I need to incorporate additional software components like node.js or a PHP interpreter?

Any assistance would be greatly appreciated. Thank you.

Answer №1

Experience the power of Superlogin, a cutting-edge NodeJS login framework designed to seamlessly integrate with CouchDb logins.

Recently implemented into one of my mobile apps, this Authentication API proved to be incredibly user-friendly. The detailed documentation and demo app code provided a solid foundation for integration. Despite being newly open sourced, the code's maturity and extensive test coverage create an impression of long-standing production use. The developer's responsiveness and assistance further enhance the overall experience.

  • Boasting a robust server API and an Optional Angular client API
  • Includes a comprehensive demo app
  • Supports local username/password authentication, password reset, update, and user profile management
  • Allows attachment of multiple social OAuth logins (such as Facebook, Twitter, Google) per user account leveraging the powerful PassportJS framework supporting over 300 authentication plugins
  • Integration with SendGrid API for email verification and sending user notifications
  • Generates temporary secure CouchDb user/password pairs per session, enabling easy replication into PouchDb using Basic Auth with enhanced security measures
  • 100% cookie-free setup to prevent CSRF attacks
  • Fast and scalable performance with the option to utilize Redis session store
  • Comprehensive test suite ensures reliability

If you're interested, take a look at the latest Hoodie project on .

This project features an API designed for managing CouchDb user accounts. Here are some of the functions available:

// sign up
hoodie.account.signUp('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="375d585277524f565a475b521954585a">[email protected]</a>', 'secret');

// sign in
hoodie.account.signIn('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bed4d1dbfedbc6dfd3ced2db90ddd1d3">[email protected]</a>', 'secret');

// sign out
hoodie.account.signOut();

// change password
hoodie.account.changePassword('currentpassword', 'newpassword');

// change username
hoodie.account.changeUsername('currentpassword', 'newusername');

// reset password
hoodie.account.resetPassword('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="90fafff5d0f5e8f1fde0fcf5bef3fffd">[email protected]</a>');

// destroy account and all its data
hoodie.account.destroy();

// find out who the currently logged in user is (returns undefined if none)
hoodie.account.username;

Additionally, there are events that can be triggered:

// user has signed up (this also triggers the authenticated event, see below)
hoodie.account.on('signup', function (user) {});

// user has signed in (this also triggers the authenticated event, see below)
hoodie.account.on('signin', function (user) {});

// user has signed out
hoodie.account.on('signout', function (user) {});

// user has re-authenticated after their session timed out (this does _not_ trigger the signin event)
hoodie.account.on('authenticated', function (user) {});

// user's session has timed out. This means the user is still signed in locally, but Hoodie cannot sync remotely, so the user must sign in again
hoodie.account.on('unauthenticated', function (user) {});

While I don't have personal experience working with couchDB, my understanding is that it functions as a database and requires a server-side language for interaction from the browser. Possible choices for this include Node.js and PHP (though I've heard that couchdb has particularly good support for node.js). Here's a potential setup using node.js:

Answer №4

Couchdb offers robust security features to handle authentication at both the couch level and database level. Learn more about these security features here.

The _users database stores all user information, while users can be protected using _security documents for database-level security.

While document level security requires custom implementation, it is recommended to follow a database per user model for enhanced security.

Additionally, BrowserID (Persona) can be integrated with Couchdb using this link.

If you are developing a couchapp, Kan.so offers convenient packages for creating users from the front end and managing them effectively.
