ESLint

ESLint is the industry-standard static analysis tool for identifying and fixing problems in JavaScript and TypeScript codebases, configured via modern Flat Config (eslint.config.js).

When to Use

• Static Code Analysis for JavaScript/TypeScript: Catching bugs, anti-patterns, and syntax errors before code review.
• Modern ESLint Flat Config (eslint.config.js): Unified, composable configuration format in ESLint v9+.
• Enforcing TypeScript Best Practices: Integrating @typescript-eslint with type-aware lint rules.
• Team Code Standardization: Automating rule compliance across React, Next.js, Vue, and Node.js codebases.

Quick Start

// eslint.config.mjs (Modern Flat Config)
import js from "@eslint/js";
import tseslint from "typescript-eslint";
