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

To set up ESLint, Prettier, Astro, and React rules in your eslint.config.js file, you'll need to follow a few steps. However, the knowledge sources provided do not contain specific instructions for setting up all these tools in a single eslint.config.js file.

Here's what we can gather from the provided sources:

  1. ESLint: ESLint (https://eslint.org/) is a popular linter for JavaScript and JSX. For Astro support, you can install a community maintained plugin (https://github.com/ota-meshi/eslint-plugin-astro). You can find more information on how to install and set up ESLint for your project in the project’s User Guide (https://ota-meshi.github.io/eslint-plugin-astro/user-guide/).

  2. Prettier: Prettier (https://prettier.io/) is a popular formatter for JavaScript, HTML, CSS, and more. If you're using the Astro VS Code Extension or the Astro language server within another editor, code formatting with Prettier is included. To add support for formatting .astro files outside of the editor (e.g. CLI) or inside editors that don’t support Astro's editor tooling, install the official Astro Prettier plugin (https://github.com/withastro/prettier-plugin-astro). You can install prettier and prettier-plugin-astro using npm, pnpm, or Yarn. For example, with npm, you would run:

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

    Then, create a .prettierrc.mjs config file at the root of your project and add prettier-plugin-astro to it. You can then run the command prettier . --write in the terminal to format your files.

#

  1. Astro: You can customize how Astro works by adding an astro.config.mjs file in your project. This file exports its configuration using the default export, using the recommended defineConfig helper. Astro supports several file formats for its JavaScript configuration file: astro.config.js, astro.config.mjs, astro.config.cjs and astro.config.ts.

  2. React: The knowledge sources do not provide specific instructions for setting up React-specific rules in ESLint. However, you can typically use the eslint-plugin-react package to apply React-specific linting rules.

Please note that the specific configuration for these tools will depend on your project's requirements and the specific rules you want to enforce. You may need to refer to the documentation for each tool for more detailed setup instructions.
