Ruby on Rails 8 and Hotwire : Build a Password Manager

Build a modern Full-stack Ruby on Rails Web Application with a secure JSON API and a Google Chrome Extension

In this course, we're going to build a password manager inspired by popular applications like 1Password and LastPass. Our 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 our Rails backend.

We'll begin by creating a Ruby on Rails 8, Full-stack web application. Leveraging the power of Hotwire, we'll create a lightning-fast Single Page Application (SPA). We'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 our database.

Next, while working in the same Ruby on Rails 8 web application we'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, we'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. We'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.

CHANGELOG:
