Here’s a comprehensive README.md for your repository, cardano-svelte-effect-nix-template, highlighting its features and providing guidance on using it with Nix:
⸻
Cardano Svelte Effect Nix Template
A fully reproducible, Nix-powered template integrating Svelte and Effect, tailored for building Cardano-related applications with a modern frontend stack. 
🚀 Features • Reproducible Builds: Leverages Nix flakes to ensure consistent builds across environments. • Svelte Integration: Utilizes Svelte for a reactive and efficient frontend experience. • Effect Integration: Incorporates the Effect library for robust functional programming capabilities. • Cardano Compatibility: Pre-configured to facilitate development of Cardano-centric applications. • Development Environment: Provides a comprehensive dev shell with essential tools. • Testing Suite: Includes Vitest for unit and integration testing. • Code Formatting: Employs Prettier and nixpkgs-fmt for consistent code styling.  
🧰 Getting Started
Prerequisites
Ensure you have the following installed: • Nix with experimental features enabled:
mkdir -p ~/.config/nix echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf
• Direnv (optional but recommended for environment management)
Initialization
To create a new project using this template:
nix flake init -t github:sempruijs/cardano-svelte-effect-nix-template
This command initializes a new Nix flake based on the template. 
🛠️ Development
Entering the Development Shell
To enter a development environment with all necessary tools: 
nix develop
This shell includes:  • Node.js and npm • TypeScript • Svelte Language Server • Tailwind CSS Language Server • Prettier • Vitest 
Running the Development Server
To start the development server with hot module replacement: 
nix run .#dev
This will launch the Vite development server, typically accessible at http://localhost:5173.
🧪 Testing
To execute the test suite:
nix run .#test
This runs all tests using Vitest, ensuring your application behaves as expected. 
🏗️ Building
To build the application for production:
nix build
The output will be located in the ./result directory. 
🌐 Previewing
To preview the built application: 
nix run
This serves the application using miniserve at http://localhost:8080, supporting single-page application (SPA) routing. 
🎨 Formatting
To format the codebase: 
nix fmt
This command formats:  • TypeScript, JavaScript, JSON, Markdown, Svelte, HTML, and CSS files using Prettier • Nix files using nixpkgs-fmt
