Updated May 24, 2025
Price: $12.99

Description

In this course, you'll build a password manager inspired by popular applications like 1Password and LastPass. The application will enable users to create secure accounts, allowing them to store login credentials for their favorite websites. These credentials will be easily accessible through a Chrome Extension, powered by a secure, robust JSON API from a Rails backend.

You'll begin by creating a Ruby on Rails 8, Full-stack web application. Leveraging the power of Hotwire, you'll create a lightning-fast Single Page Application (SPA). You'll also take advantage of advanced Rails 8 tools such as Active Record Encryption, ensuring sensitive user information like usernames and passwords are securely encrypted and safely stored in the database.

Next, while working in the same Ruby on Rails 8 web application, you'll start building out a secure JSON API, implementing user authentication using JSON Web Tokens (JWT). Users who successfully authenticate will receive an expiring token to securely fetch their data through subsequent requests.

Finally, you'll use the Google Chrome Extension API and Hotwire (yes, you can use Hotwire outside of Rails!) to build a similar version of our web application as a Chrome Extension. You'll cover essential topics such as using local storage, communicating between the Popup and Content Script, retrieving URLs from active tabs, and automatically filling login forms with a single click.
