[rapid solstice]

How do I use the ESLint Astro plugin with my eslint.config.ts file?

Hi @rapid solstice. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To use the ESLint Astro plugin with your project, you need to install the community-maintained plugin eslint-plugin-astro. The knowledge sources provide a link to the plugin and its user guide, but do not include step-by-step instructions or a code example specifically for configuring it with an eslint.config.ts file.

You should refer to the project's User Guide for detailed installation and setup instructions, as the official Astro documentation does not provide explicit configuration steps for eslint.config.ts files. The documentation only confirms that the plugin exists and is the recommended way to add ESLint support for Astro projects Editor setup: ESLint.

I'm sorry, but the knowledge sources do not contain enough information to provide a full example of configuring eslint.config.ts with the Astro ESLint plugin. Please consult the plugin's user guide for up-to-date and detailed setup instructions.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@rapid solstice Kapa.ai is still learning and improving, please let me know how I did by reacting below.

@latent scaffold what about the Astro Prettier plugin? How do I add it using my .prettierrc file?

Let me check the knowledge base for you again. One moment! :books:

To add the official Astro Prettier plugin to your project using a .prettierrc file, follow these steps:

1. Install Prettier and the Astro Prettier plugin:

   npm install --save-dev --save-exact prettier prettier-plugin-astro
   

2. Create a .prettierrc configuration file in the root of your project and add the following content:

   {
     "plugins": ["prettier-plugin-astro"],
     "overrides": [
       {
         "files": "*.astro",
         "options": {
           "parser": "astro"
         }
       }
     ]
   }
   

   This configuration ensures that Prettier uses the Astro parser for .astro files and applies the plugin correctly.

3. (Optional) If you use other Prettier plugins (like Tailwind), list them in the plugins array, making sure prettier-plugin-tailwindcss is last:

   {
     "plugins": [
       "prettier-plugin-astro",
       "prettier-plugin-tailwindcss"
     ],
     "overrides": [
       {
         "files": "*.astro",
         "options": {
           "parser": "astro"
         }
       }
     ]
   }
   

For more details, see the Astro documentation on Prettier setup and the plugin’s README Editor setup: Prettier.
