What is eslint-mdx?
The eslint-mdx package is an ESLint plugin that provides linting support for MDX (Markdown with JSX) files. It helps ensure code quality and consistency in MDX files by leveraging ESLint's capabilities.
What are eslint-mdx's main functionalities?
Linting MDX Files
This configuration allows ESLint to lint MDX files by extending the recommended settings provided by the eslint-mdx plugin.
module.exports = {
"overrides": [
{
"files": ["*.mdx"],
"extends": ["plugin:mdx/recommended"]
}
]
};
Custom MDX Rules
This configuration demonstrates how to add custom rules for MDX files. In this example, the rule 'mdx/no-jsx-html-comments' is set to 'error' to disallow HTML comments within JSX.
module.exports = {
"overrides": [
{
"files": ["*.mdx"],
"extends": ["plugin:mdx/recommended"],
"rules": {
"mdx/no-jsx-html-comments": "error"
}
}
]
};
Integrating with Prettier
This configuration shows how to integrate Prettier with eslint-mdx to ensure consistent formatting in MDX files. The 'prettier/prettier' rule is configured to use the 'mdx' parser.
module.exports = {
"overrides": [
{
"files": ["*.mdx"],
"extends": ["plugin:mdx/recommended", "prettier"],
"rules": {
"prettier/prettier": ["error", { "parser": "mdx" }]
}
}
]
};
Other packages similar to eslint-mdx
eslint-plugin-markdown
eslint-plugin-markdown is an ESLint plugin that allows linting of JavaScript code blocks within Markdown files. Unlike eslint-mdx, which is specifically designed for MDX files, eslint-plugin-markdown focuses on JavaScript code within standard Markdown files.
remark-lint
remark-lint is a plugin for remark, a Markdown processor, that provides linting capabilities for Markdown files. While eslint-mdx leverages ESLint for linting MDX files, remark-lint is part of the remark ecosystem and focuses on Markdown linting with its own set of rules and plugins.
eslint-plugin-react
eslint-plugin-react is an ESLint plugin that provides linting rules for React applications. Although it is not specifically designed for MDX files, it can be used in conjunction with eslint-mdx to ensure React code within MDX files adheres to best practices.
