# ⚙️ Configuration

To configure Astro, add an `astro.config.mjs` file in the root of your project. All settings are optional. Here are the defaults:

```js
export default {
  projectRoot: '.',         // Where to resolve all URLs relative to. Useful if you have a monorepo project.
  pages: './src/pages',     // Path to Astro components, pages, and data
  dist: './dist',           // When running `astro build`, path to final static output
  public: './public',       // A folder of static files Astro will copy to the root. Useful for favicons, images, and other files that don’t need processing.
  buildOptions: {
    // site: '',            // Your public domain, e.g.: https://my-site.dev/. Used to generate sitemaps and canonical URLs.
    sitemap: true,          // Generate sitemap (set to "false" to disable)
  },
  devOptions: {
    port: 3000,             // The port to run the dev server on.
    // tailwindConfig: '',  // Path to tailwind.config.js if used, e.g. './tailwind.config.js'
  },
  // component renderers which are enabled by default
  renderers: [
    '@astrojs/renderer-svelte',
    '@astrojs/renderer-vue',
    '@astrojs/renderer-react',
    '@astrojs/renderer-preact'
  ],
};
```
