Tool npm

ESLint

The pluggable JavaScript and TypeScript linter that finds and fixes code problems through a fully customizable, plugin-based rule engine.

prettier

An opinionated code formatter that enforces consistent style across every language your project speaks.

typescript-eslint

The official meta-package bundling the TypeScript ESLint parser, plugin, and rule presets behind a single typed config() helper.

eslint-config-prettier

Disables ESLint stylistic rules that conflict with Prettier, so the two tools never fight over formatting.

globals

A single JSON file of global identifiers for every JavaScript environment, used by ESLint and other static analysis tools.

eslint-plugin-react

React-specific linting rules for ESLint that catch JSX bugs, enforce Hooks conventions, and keep prop usage consistent.

lint-staged

Run linters and formatters only against the files staged in git, so a slow full-project lint never blocks a commit.

eslint-plugin-import

ESLint rules that validate ES module import/export syntax and catch broken paths before they hit your build.

eslint-plugin-prettier

Run Prettier as an ESLint rule that reports formatting differences as autofixable lint errors.

Oxlint

Rust-based JavaScript/TypeScript linter that runs 50-100x faster than ESLint, with zero configuration required.

eslint-plugin-jsx-a11y

Static ESLint rules that catch JSX accessibility issues before code ships.

prettier-plugin-tailwindcss

Prettier plugin that automatically sorts Tailwind CSS classes into a consistent order

Stylelint

An extensible CSS linter that catches errors and enforces consistent styling conventions.

eslint-import-resolver-typescript

A TypeScript-aware module resolver that plugs into eslint-plugin-import(-x) so ESLint can correctly follow .ts/.tsx imports, tsconfig paths, and package export maps.
