];Understanding Code & Data Generation
ESLint is the standard JavaScript and TypeScript linter, catching errors, enforcing coding standards, and preventing anti-patterns across codebases. ESLint configuration defines which rules are active, at what severity (off, warn, error), and which plugins extend the rule set. With ESLint 9's flat config format, configuration uses eslint.config.js with exported arrays of config objects. The right ESLint setup catches bugs before they reach code review, enforces consistent style across teams, and automates coding standards that would otherwise require manual enforcement.
Generate ESLint configuration files using a visual builder. Choose from popular presets (ESLint Recommended, Airbnb, Standard, Google, XO), enable TypeScript support, add React/Vue/Angular plugins, configure individual rules, and set environment globals. Supports both flat config (eslint.config.js) and legacy (.eslintrc.json) formats.
The Devkitr ESLint Config Generator builds ESLint configuration files through interactive selection. Choose your project type (JavaScript, TypeScript, React, Vue, Node.js), select rule presets, and configure individual rules — then download a ready-to-use eslint.config.js or .eslintrc.json file.
In a typical development workflow, ESLint Config Generator becomes valuable whenever you need to build eslint configurations visually with popular presets and custom rules. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based generation tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since ESLint Config Generator processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.
Key Features
Framework Presets
Select presets for React, Vue, Angular, Next.js, Node.js, and TypeScript that include appropriate plugins and rule configurations.
Rule Browser
Browse ESLint rules by category (possible errors, suggestions, layout) with descriptions and toggle between off, warn, and error severity.
Flat Config and Legacy Support
Generate ESLint 9 flat config (eslint.config.js) or legacy format (.eslintrc.json) depending on your ESLint version.
Prettier Integration
Configure eslint-config-prettier to disable formatting rules that conflict with Prettier, and eslint-plugin-prettier to run Prettier as an ESLint rule.
How to Use ESLint Config Generator
Select Project Type
Choose JavaScript or TypeScript, and select your framework — React, Vue, Angular, Next.js, Express, or plain Node.js.
Choose Base Presets
Select from eslint:recommended, plugin:@typescript-eslint/recommended, plugin:react/recommended, and other standard presets.
Configure Rules
Browse and toggle individual rules you want to add, modify, or disable beyond the preset defaults.
Download Config File
Download the ESLint configuration file and place it in your project root. Run npx eslint . to lint your codebase.
Use Cases
New Project Setup
Generate a comprehensive ESLint configuration when starting new projects to establish coding standards from the first commit.
TypeScript Migration
Build ESLint config with @typescript-eslint rules when migrating a JavaScript project to TypeScript, catching type-related issues.
Team Standardization
Create a shared ESLint config that enforces consistent coding patterns across all team projects and repositories.
Prettier Co-Configuration
Set up ESLint alongside Prettier with proper conflict resolution so both tools work harmoniously without rule conflicts.
Pro Tips
Start with eslint:recommended and add rules incrementally. Enabling too many rules at once on an existing codebase produces overwhelming error counts.
Use "error" severity for rules that catch genuine bugs, "warn" for style preferences that shouldn't block CI, and "off" for rules you disagree with.
Configure ESLint to run in your CI pipeline so lint errors block merges. Use --max-warnings 0 to treat warnings as errors in CI.
Use ESLint's --fix flag to auto-fix formatting and simple code issues. Many rules have auto-fixers that save manual correction time.
Common Pitfalls
Enabling all available rules without understanding their purpose
Fix: Start with recommended presets and add rules you specifically need. Hundreds of enabled rules create noise, hiding genuine issues in a flood of style warnings.
Not configuring eslint-config-prettier when using both ESLint and Prettier
Fix: ESLint and Prettier have overlapping formatting rules that conflict. Add eslint-config-prettier to disable ESLint's formatting rules.
Ignoring ESLint warnings without addressing or explicitly disabling them
Fix: Either fix warnings, change them to errors, or explicitly turn them off. Accumulated warnings train developers to ignore linter output entirely.
Frequently Asked Questions
QWhich config formats are supported?
Both the new flat config format (eslint.config.js for ESLint 9+) and legacy format (.eslintrc.json) are supported.
QDoes it support TypeScript?
Yes. Enable TypeScript support to add @typescript-eslint/parser and recommended TypeScript rules.
QCan I customize individual rules?
Yes. Toggle popular rules on/off and set their severity (off, warn, error) with the visual rule configurator.
