Installing a Vite or Rollup plugin

Astro builds on top of Vite, and supports both Vite and Rollup plugins. This recipe uses a Rollup plugin to add the ability to import a YAML (.yml) file in Astro.

1. Install @rollup/plugin-yaml:

   npm install @rollup/plugin-yaml --save-dev

2. Import the plugin in your astro.config.mjs and add it to the Vite plugins array:

   import { defineConfig } from 'astro/config';
   import yaml from '@rollup/plugin-yaml';
   
   export default defineConfig({
     vite: {
       plugins: [yaml()]
     }
   });

3. Finally, you can import YAML data using an import statement:

   import yml from './data.yml';
