A full-stack React/SSR framework with file-based routing, middleware, and server actions.

📚 Table of Contents

🎯 What is Leeforge Fusion?

Leeforge Fusion is a modern full-stack framework built on Solid.js that provides:

File-based routing with automatic code generation
Server-side rendering with seamless hydration
Middleware system for authentication, logging, and more
Server actions for type-safe RPC
Zero configuration - works out of the box
Developer experience with HMR and clear errors

🚀 Quick Start

Installation

npm install leeforge-fusion solid-js @tanstack/solid-router @tanstack/solid-query

Basic Usage

Create your app structure:

src/app/
├── layout.tsx      # Root layout
├── index.tsx       # Home page (/)
└── about.tsx       # About page (/about)

Create a page:

// src/app/index.tsx
export default function Home() {
  return <h1>Welcome to Leeforge Fusion!</h1>;
}

Start development:

npm run dev

Build for production:

npm run build
npm run preview

📖 Usage Guide

Leeforge Fusion provides a comprehensive set of features for building modern full-stack applications. Here's how to use each core feature:

1. File-Based Routing

Automatic route generation from your src/app/ directory:

src/app/
├── index.tsx           → /
├── about.tsx           → /about
├── blog/
│   ├── index.tsx       → /blog
│   └── [id].tsx        → /blog/:id
└── (dashboard)/
    └── settings.tsx    → /dashboard/settings

Features:

Dynamic routes: [id].tsx - Access params via Route.useParams()
Route groups: (dashboard)/ - Organize routes without affecting URL
Layouts: layout.tsx - Hierarchical layouts
Error boundaries: error.tsx - Automatic error handling
Loading states: loading.tsx - Loading UI while data fetches

Example - Dynamic Route:

// src/app/blog/[id].tsx
import { Route } from "@tanstack/solid-router";

export default function BlogPost() {
  const { id } = Route.useParams();

  return <article>Post ID: {id}</article>;
}

Example - Layout:

// src/app/layout.tsx
export default function Layout({ children }: any) {
  return (
    <html>
      <head>
        <title>My App</title>
      </head>
      <body>
        <header>My Header</header>
        <main>{children}</main>
        <footer>My Footer</footer>
      </body>
    </html>
  );
}

2. Server-Side Rendering

Full SSR support with automatic hydration:

// src/app/blog/[id].tsx
import { createServerData } from "leeforge-fusion/data";
import { Route } from "@tanstack/solid-router";

export default function BlogPost() {
  const { id } = Route.useParams();

  const post = createServerData(async ({ params }) => {
    const res = await fetch(`https://api.example.com/posts/${params.id}`);
    return res.json();
  });

  return <article>{post().title}</article>;
}

Features:

Automatic hydration: Client-side hydration happens automatically
Data fetching: Server-side data loading with createServerData
Streaming: Progressive HTML streaming for faster TTFB
Caching: Intelligent caching strategies

3. Middleware System

Hono-based middleware for cross-cutting concerns with route guards:

// src/middleware/auth.ts
import {
  requireAuth,
  requireAdmin,
  requireGuest,
  createMiddleware,
} from "leeforge-fusion/middleware";

// Route guards
export const authMiddleware = requireAuth();
export const adminMiddleware = requireAdmin();
export const guestMiddleware = requireGuest();

// Custom middleware
export const logMiddleware = createMiddleware(async (ctx, next) => {
  console.log(`${ctx.req.method} ${ctx.req.path}`);
  await next();
});

// Combined middleware chain
export const adminOnly = [requireAuth(), requireAdmin()];

Route Guard Features:

✅ requireAuth(): Redirects to /login if no user
✅ requireAdmin(): Redirects to /unauthorized if not admin
✅ requireGuest(): Redirects to /dashboard if user exists
✅ createGuardChain(): Combine multiple guards
✅ defineGuard(): Create custom guards

Usage in Routes:

// framework.config.ts
import { requireAuth, requireAdmin } from "leeforge-fusion/middleware";

export default defineConfig({
  routes: {
    "/admin/*": [requireAuth(), requireAdmin()],
    "/dashboard/*": [requireAuth()],
    "/login": [requireGuest()],
  },
});

4. Server Actions

Type-safe server-side functions:

// src/app/api/actions.ts
export async function createPost(data: { title: string; content: string }) {
  // Server-only code
  return { id: Date.now(), ...data };
}

// In component
import { useServerAction } from "leeforge-fusion/client";

function CreatePost() {
  const [create, { loading }] = useServerAction(createPost);

  return (
    <form onSubmit={create}>
      <input name="title" />
      <button disabled={loading}>Create</button>
    </form>
  );
}

Features:

Type-safe: Full TypeScript support
Automatic serialization: No manual JSON parsing
Error handling: Built-in error boundaries
Loading states: Automatic loading state management

5. Configuration

Type-safe configuration with guards:

// framework.config.ts
import { defineConfig } from "leeforge-fusion/config";
import { requireAuth, requireAdmin } from "leeforge-fusion/middleware";

export default defineConfig({
  routes: {
    "/admin/*": [requireAuth(), requireAdmin()],
  },
  api: {
    prefix: "/api",
  },
});

Configuration Options:

routes: Route guards and middleware
api: API configuration (prefix, timeout)
ssr: SSR configuration (render mode, timeout)
vite: Vite configuration (merged with defaults)

Test Architecture

Unit Tests (Vitest)

Fast, isolated tests for individual components:

// tests/unit/middleware/route-guard.test.ts
import { describe, test, expect } from "vitest";
import { requireAuth, defineGuard } from "../../src/middleware/route-guard";

describe("Route Guards", () => {
  test("requireAuth passes when user exists", async () => {
    const ctx = {
      user: { id: "123", role: "user" },
      params: {},
      request: new Request("http://localhost"),
    };

    await expect(requireAuth(ctx)).resolves.not.toThrow();
  });
});

Integration Tests (Vitest)

Tests component integration and SSR flows:

// tests/integration/ssr.test.ts
import { describe, test, expect } from "vitest";
import {
  createGuardChain,
  defineGuard,
} from "../../src/middleware/route-guard";

describe("SSR Integration", () => {
  test("guard chain integration", async () => {
    const guard1 = defineGuard((ctx) => {
      if (!ctx.user) throw redirect("/login");
    });

    const chain = createGuardChain(guard1);
    const ctx = {
      user: { id: "1" },
      params: {},
      request: new Request("http://localhost"),
    };

    await expect(chain(ctx)).resolves.not.toThrow();
  });
});

E2E Tests (Playwright)

Full browser automation testing real user flows:

// tests/e2e/basic-flow.spec.ts
import { test, expect } from "@playwright/test";

test.describe("基本用户流程", () => {
  test("访问首页", async ({ page }) => {
    await page.goto("/");
    await expect(page).toHaveTitle(/Leeforge/);
  });
});
