Rabble is a real-time messaging app modeled after Discord and Slack. It has a Sveltekit frontend using SSR (Server Side Rendering) and uses TailwindCSS + DaisyUI for styling. User authentication and data is stored within a Pocketbase SQL-lite database and communicates with the backend through Node.js. It is currently live for testing here and is being hosted for free with Vercel.
One of the key lessons from this project was managing client-side security. The code is written so the user never is able to see or iteract with server calls directly and any client information is passed to the database through a sveltekit middle layer. This could eventually allow for server side data validation and rate limiting.
