# ⚙️ 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' ], }; ```
