How to Use ESLint Config Generator
Choose Framework
Select React, Vue, Next.js, Node.js, or TypeScript as your base.
Configure Rules
Toggle popular linting rules and select plugins (Prettier, import, security).
Generate Config
Get a complete .eslintrc.json or eslint.config.js. Copy it to your project root.
ESLint Config Generator: the essentials
The ESLint Config Generator builds a starting `.eslintrc.json` (or new flat `eslint.config.js`) from a checkboxes-and-toggles UI for env, parser, framework, and common rules. Skips the back-and-forth of installing eslint, running `--init`, then realizing you wanted TypeScript-aware rules and a Next.js preset.
Key points
- Processes configuration and code locally, your project data never leaves your browser.
- Validates against common standards and best practices for the domain.
- Works offline once loaded, no active internet connection required for processing.

Technical Deep Dive
ESLint Config Generator
Generate standard `.eslintrc.json` or `.js` rulesets tailored for your stack. Select environments (Browser, Node), frameworks (React, Next.js), and TypeScript support, then easily configure essential rules to kickstart your linting setup without manual lookup.
Flat config output
Pick your framework, TypeScript, Prettier, and import rules, and get a modern eslint.config.js (or legacy .eslintrc).
Install line included
Lists the exact devDependencies for the plugins and configs you selected.

01 Plugin Layering Architecture
| Configuration Layer | Target Context | Resolution Priority |
|---|---|---|
| Base Standard | Core JS Errors | Lowest (Foundation) |
| TypeScript Engine | Type-Aware Checks | Overrides Base JS |
| Framework Rules | React / Next.js Patterns | Domain-Specific Context |
| Prettier Conflict Resolution | Formatting Rules | Highest (Disables Styles) |

03 ESLint Flat Config (eslint.config.js) Migration
-
The Flat Config Era ESLint v9+ uses a new flat config format (eslint.config.js) replacing the legacy .eslintrc.* files. The flat config uses native ES modules, eliminates the extends/overrides complexity, and makes configuration composable through array spreading. This tool generates configs compatible with both legacy and flat formats.

Popular Preset Combinations The most battle-tested ESLint configurations: eslint-config-airbnb (strict, opinionated), @typescript-eslint/recommended (TypeScript-specific rules), eslint-plugin-react-hooks (React Hooks rules of hooks), and eslint-config-prettier (disables formatting rules that conflict with Prettier). Stack them in order of specificity.
