MinimactThe Posthydrationist Framework

Quick Start ​

# Install the .NET tool
dotnet tool install -g minimact

# Create new ASP.NET project with Minimact
dotnet minimact new MyApp
cd MyApp

# Install client dependencies (13.33 KB gzipped by default)
cd client
npm install

# Start dev mode (watches TSX, transpiles to C#, runs server)
npm run dev

Two versions available:

• minimact — 13.33 KB gzipped (WebSocket-based, modern browsers)
• minimact-r — 25.03 KB gzipped (Full SignalR with fallbacks)

Example ​

Write familiar React code:

import { useState } from 'minimact';

export function Counter() {
  const [count, setCount] = useState(0);

  return (
    <button onClick={() => setCount(count + 1)}>
      Count: {count}
    </button>
  );
}

Babel transpiles to C#, Rust predicts the next state, and the client applies cached patches instantly (~2-3ms).

Why Minimact? ​

For React Developers ​

Finally, a path to .NET without learning Razor. Keep writing React — get ASP.NET Core's power, security, and enterprise features.

Bundle size: 13.33 KB vs React's 45 KB (71% smaller!)

For .NET Teams ​

Modern frontend DX without abandoning your stack. Your team already knows C# and EF Core. Now they can build UIs with React syntax.

Performance: 2-3ms interactions vs 47ms traditional SSR

For CTOs ​

Solve the "React DX + .NET backend" problem. One stack, one deployment, full type safety from database to DOM. Rust-powered performance makes ASP.NET Core shine.

Comparison:

• React 18: 45 KB gzipped
• Vue 3: 34 KB gzipped
• Minimact: 13.33 KB gzipped (71% smaller than React)

Better Than Blazor ​

Blazor requires learning Razor syntax. Minimact uses React — the syntax millions of developers already know. Lower barrier, faster adoption, bigger talent pool.
