CompositionalIT/SAFE-Dojo

This system is a self-study educational repository designed to demonstrate the SAFE (Saturn, Fable, ASP.NET, Elmish) stack on .NET 8. It provides a scaffolded full-stack application that integrates a Vite-based F\# frontend with a Saturn-based API server to fetch and display location, crime, and weather data. The codebase serves as a modernized reference implementation, replacing legacy build tools and sample projects with a structured multi-project layout for learning purposes.

The server project has been initialized using the SAFE (Saturn, Fable, ASP.NET, Elmish) template, introducing a new API layer built on Fable.Remoting and Saturn. This change adds the core server files (Api.fs, DataAccess.fs, Server.fs) which define the application's entry point and expose endpoints for calculating distances from London, retrieving crime reports, and fetching weather data. The implementation utilizes FSharp.Data for JSON parsing to interact with external services like postcodes.io, data.police.uk, and open-meteo.com, while enforcing postcode validation on all incoming requests.

Added a new Shared module defining core domain types including LatLong, Location, LocationResponse, CrimeResponse, and WeatherResponse, along with a WeatherType discriminated union that maps WMO weather codes to specific weather conditions and icons. The module also exposes an IDojoApi interface for client-server communication and a postcode validation helper using Regex, establishing the shared contract between the client and server layers.

The src/Client directory now contains the initial SAFE Dojo student exercise, providing a complete Elmish-based frontend scaffold. The application uses Vite for build tooling (replacing Webpack) and Feliz with Bulma for the UI, integrating PigeonMaps for map visualization, Recharts for crime data bar charts, and SweetAlert for error handling. The entry point (App.fs) initializes the Elmish program, while Index.fs defines the core model, message handling for postcode lookups, and view components for displaying location, crime statistics, and map markers. The setup includes a Vite configuration for API proxying and a set of Paket dependencies to support these libraries.

The legacy SaturnSample application has been removed from the codebase. This change deletes the entire \src/SaturnSample\ directory, including the F\# source files for the server configuration, routing, database wrappers, and HTML templates, as well as the associated static assets (CSS/JS) and dependency references. Users will no longer have access to this specific sample implementation.

The SAFE Dojo self-study repository has been upgraded to target .NET 8.0 (global.json) and replaced the legacy FAKE build scripts (build.fsx, build.cmd, build.sh) with a new Build.fs project using FAKE 5. The client-side build tooling has switched from webpack to Vite, enabling hot module replacement for the Fable/Elmish frontend. The solution structure was reorganized from a single SaturnSample project to a multi-project SAFE layout (Shared, Server, Client) with a dedicated Build project, and Azure deployment is now handled via the Farmer library.

(repo-wide) · high confidence

The project has been upgraded to the SAFE v5 template, migrating the build and runtime targets from .NET Core 2.0 to .NET 8. This change replaces the legacy Saturn and Simple.Migrations dependencies with modern equivalents like Fable.Remoting.Giraffe, Feliz, and Expecto, and switches the JavaScript build tooling from Webpack to Vite. The solution structure has been simplified by removing the old SaturnSample project and renaming the Migrations project to Shared, while adopting Paket for dependency management.
