Question 1

Is eslint-plugin-n a better choice than the original eslint-plugin-node?

Accepted Answer

Yes, for most projects, as eslint-plugin-n is actively maintained while the original is abandoned. However, migration might require updating configurations due to potential rule differences or deprecations, so assess your existing setup first.

Question 2

How do I configure eslint-plugin-n for a project with both CommonJS and ES modules?

Accepted Answer

Use the exported flat config flat/mixed-esm-and-cjs, as shown in the FAQ section. This handles mixed module types automatically, but you may need to adjust rules like exports-style based on your preference.

Question 3

Does eslint-plugin-n work with TypeScript and @typescript-eslint?

Accepted Answer

It can be used alongside @typescript-eslint for Node.js-specific rules, but you'll need to configure both plugins carefully. Focus on Node.js linting, as @typescript-eslint handles TypeScript syntax and types.

Question 4

What's the difference between recommended-module and recommended-script configs?

Accepted Answer

recommended-module treats all files as ES modules, while recommended-script treats them as CommonJS. Choose based on your project's module system; for mixed setups, use the flat/mixed-esm-and-cjs config.

Question 5

How does eslint-plugin-n detect which Node.js version to lint for?

Accepted Answer

It checks in order: rule configuration, ESLint settings, package.json engines field, and defaults to >=16.0.0. Using the engines field is recommended for accurate version targeting.

Question 6

Can I use eslint-plugin-n for front-end React or Vue projects?

Accepted Answer

Only if they involve Node.js code, such as server-side rendering or build scripts. For pure front-end linting, stick to plugins like eslint-plugin-react or eslint-plugin-vue, as eslint-plugin-n's rules are Node.js-specific.
