FossaApp Bridge

The FossaApp Bridge provides shared frontend and backend functionality.

Project Purpose

The Fossa.Bridge project is a shared F# library designed to encapsulate logic, validation, and domain models that are common to both the .NET backend and the TypeScript/JavaScript frontend. By using Fable, the F# code is transpiled into JavaScript/TypeScript for the frontend environment while simultaneously being compiled into a standard .NET library for the backend. This ensures a single source of truth for core business logic, API models, and data validation rules, reducing duplication and preventing synchronization issues between the client and server.

Package Usage

For .NET Backends (C# / F#)

Install the NuGet package:

dotnet add package Fossa.Bridge

For JavaScript / TypeScript Frontends

Install the NPM package:

npm install @fossa-app/bridge

or using Yarn:

yarn add @fossa-app/bridge

Features

• Shared API domain models.
• Common validation and helper logic.
