+# File-System Routing
+
+FUNSTACK Static does not include a built-in file-system router, but you can implement one in userland using Vite's `import.meta.glob` and a router library like [FUNSTACK Router](https://github.com/uhyo/funstack-router).
+
+## How It Works
+
+The idea is to use `import.meta.glob` to discover page components from a `pages/` directory at compile time, then convert the file paths into route definitions.
+
+```tsx
+import { route, type RouteDefinition } from "@funstack/router/server";
+
+const pageModules = import.meta.glob<{ default: React.ComponentType }>(
+  "./pages/**/*.tsx",
+  { eager: true },
+);
+
+function filePathToUrlPath(filePath: string): string {
+  let urlPath = filePath.replace(/^\.\/pages/, "").replace(/\.tsx$/, "");
+  if (urlPath.endsWith("/index")) {
+    urlPath = urlPath.slice(0, -"/index".length);
+  }
+  return urlPath || "/";
+}
+
+export const routes: RouteDefinition[] = Object.entries(pageModules).map(
+  ([filePath, module]) => {
+    const Page = module.default;
+    return route({
+      path: filePathToUrlPath(filePath),
+      component: <Page />,
+    });
+  },
+);
+```
+
+With this setup, files in the `pages/` directory are automatically mapped to routes:
+
+| File                   | Route    |
+| ---------------------- | -------- |
+| `pages/index.tsx`      | `/`      |
+| `pages/about.tsx`      | `/about` |
+| `pages/blog/index.tsx` | `/blog`  |
+
+## Why import.meta.glob?
+
+Using `import.meta.glob` has two key advantages:
+
+- **Automatic discovery** — you don't need to manually register each page. Just add a new `.tsx` file and it becomes a route.
+- **Hot module replacement** — Vite tracks the glob pattern, so adding or removing page files in development triggers an automatic update without a server restart.
+
+## Static Generation
+
+To generate static HTML for each route, derive [entry definitions](/api/entry-definition) from the route list:
+
+```tsx
+import type { EntryDefinition } from "@funstack/static/entries";
+import type { RouteDefinition } from "@funstack/router/server";
+
+function collectPaths(routes: RouteDefinition[]): string[] {
+  const paths: string[] = [];
+  for (const route of routes) {
+    if (route.children) {
+      paths.push(...collectPaths(route.children));
+    } else if (route.path !== undefined && route.path !== "*") {
+      paths.push(route.path);
+    }
+  }
+  return paths;
+}
+
+function pathToEntryPath(path: string): string {
+  if (path === "/") return "index.html";
+  return `${path.slice(1)}.html`;
+}
+
+export default function getEntries(): EntryDefinition[] {
+  return collectPaths(routes).map((pathname) => ({
+    path: pathToEntryPath(pathname),
+    root: () => import("./root"),
+    app: <App ssrPath={pathname} />,
+  }));
+}
+```
+
+This produces one HTML file per route at build time.
