This project is a simple url shortener created as a proof of concept for highly performant, hypermedia-driven applications within JavaScript. The stack is based on the BETH stack and uses the following technologies:
- Bun for runtime and package manager
- Elysia for server-side rendering
- Redis (instead of Turso) for data storage
- htmx for hypermedia-driven client rendering
The application is hosted on fly.io to bring the application to the edge, allow for autoscaling, and provide a Redis instance within the private network.
The application uses a simple counter to generate a unique ID that is base62 encoded to create a hash. This means that the unique hashes can scale infinitely but will gradually become longer in length. By not using a randomly generated hash, the application is able to avoid a database lookup to check for collisions which increases performance.
To start the development server run:
bun run devOpen http://localhost:3000/ with your browser to see the result.
