Vite Plugin: File-based Routing ​

The sigproRouter plugin for Vite automates route generation by scanning your pages directory. It creates a virtual module that you can import directly into your code, eliminating the need to maintain a manual routes array.

1. Project Structure ​

To use the plugin, organize your files within the src/pages directory. The folder hierarchy directly determines your application's URL structure.

text
my-sigpro-app/
├── src/
│   ├── pages/
│   │   ├── index.js          →  #/
│   │   ├── about.js          →  #/about
│   │   ├── users/
│   │   │   └── [id].js       →  #/users/:id
│   │   └── blog/
│   │       ├── index.js      →  #/blog
│   │       └── [slug].js     →  #/blog/:slug
│   ├── App.js                (Optional App Shell)
│   └── main.js               (Entry Point)
├── vite.config.js
└── package.json

2. Setup & Configuration ​

Add the plugin to your vite.config.js.

javascript
// vite.config.js
import { defineConfig } from 'vite';
import { sigproRouter } from 'sigpro/vite';

export default defineConfig({
  plugins: [sigproRouter()]
});

3. Implementation ​

You can implement the router either directly in your entry point or inside an App component to support persistent layouts (like a navbar that doesn't re-render).

Option A: Direct in main.js ​

Best for simple apps where the router occupies the entire viewport.

javascript
// src/main.js
import { $ } from 'sigpro';
import { Router } from 'sigpro/plugins';
import { routes } from 'virtual:sigpro-routes';

$.plugin(Router).then(() => {
  $.mount(_router(routes), '#app');
});

Option B: Inside App.js (With Layout) ​

Recommended for apps with a fixed Sidebar or Navbar.

javascript
// src/main.js
import { $ } from 'sigpro';
import { Router } from 'sigpro/plugins';

$.plugin(Router).then(() => {
  import('./App.js').then(app => $.mount(app.default, '#app'));
});

// src/App.js
import { routes } from 'virtual:sigpro-routes';

export default () => {
  return div({ class: 'layout' }, [
    header([
      h1("SigPro App"),
      nav([
        a({ href: '#/' }, "Home"),
        a({ href: '#/blog' }, "Blog")
      ])
    ]),
    // The router only swaps the content inside this <main> tag
    main(_router(routes))
  ]);
};
