开源软件介绍(OpenSource Introduction)：

Haskell/Scotty codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API.

Demo    RealWorld

This codebase was created to demonstrate a fully fledged fullstack application built with Haskell/Scotty including CRUD operations, authentication, routing, pagination, and more.

We've gone to great lengths to adhere to the Haskell/Scotty community styleguides & best practices.

For more information on how to this works with other frontends/backends, head over to the RealWorld repo.
