A full-stack Elm application server with server-side rendering, type-safe CSS, and database support, all written in Elm.
Take-home is an open-source application server built entirely in Elm, covering server-side logic, client-side rendering, and styling. It serves as a proof-of-concept for full-stack Elm development, demonstrating how Elm's architecture and type safety can unify frontend and backend code. The project explores the feasibility of writing an entire web application stack in a single language.
Elm developers and enthusiasts interested in exploring full-stack Elm applications, server-side rendering, and type-safe web development. It's also for those researching Elm's potential beyond frontend use cases.
Take-home offers a unique, all-in-Elm codebase that showcases Elm's capabilities across the stack, providing type safety from database to CSS. It's a pioneering experiment that demonstrates Elm's architectural consistency in server-side contexts, unlike traditional Node.js or Rails frameworks.
A take-home application server written in Elm and only Elm
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The entire application—server, client, and CSS—is written in Elm, demonstrating architectural unity and reducing context switching across the stack.
Uses elm-css for stylesheet creation, providing compile-time safety that eliminates runtime CSS errors, as shown in the Styles.elm files.
Renders HTML on the server and shares models between client and server code, enforcing consistent data structures, evidenced in the Shared directory.
Applies Elm's update and routing patterns to server-side logic via a modified StartApp, offering a familiar development model for Elm developers.
Explicitly labeled as a proof-of-concept in the FAQ, not suitable for production due to instability and challenges with Node.js integrations.
Requires Elm 0.16, an obsolete version, and lacks essential features like session data and easy global header/footer management, as noted in Future Work.
Integrating with Node.js libraries is difficult, leading to daily battles with mutable objects and callbacks, making the platform unstable for server-side use.
