ESLint Config Generator

Generate ESLint config files for ESLint 9 flat config, TypeScript, Bun, Vite, Nx, Yarn, Prettier, Vue, IntelliJ, and enterprise teams.

Output:A ready-to-use configuration file for ESLint Config with best practices applied.

Core Setup

- Enable @typescript-eslint parser and rules.

Enterprise Plugins

- Enforce WCAG standards in frontend apps.
- Detect potential security vulnerabilities.
- Enforce strict module import order.
- Turn off ESLint rules that conflict with Prettier.

Team Workflow

- Treat warnings as errors for CI pipelines.

Directories and files to exclude from linting (one per line).

Specify any custom rule overrides in JSON format.

What is this tool?

ESLint Config Generator is a tool that allows you to interactively build a modern ESLint configuration. It outputs an `eslint.config.js` or `eslint.config.mjs` file based on the ESLint 9 Flat Config standard, specifically tailored for enterprise environments, TypeScript, Vue, monorepos, and CI setups.

How to Use This Tool

  1. Select your target environment (e.g., Node.js, Browser, or both).
  2. Choose your framework or tooling (React, Next.js, Vue, Nx, Vite).
  3. Enable specific enterprise rules like accessibility (a11y), security, or Prettier compatibility.
  4. Review the generated eslint.config.js output in the editor.
  5. Copy the config and any required `package.json` install scripts to your project.

What This Tool Generates

  • eslint.config.js or eslint.config.mjs
  • package.json dependency installation commands
  • Setup notes for IDEs like IntelliJ or WebStorm

Enterprise Best Practices

  • Use eslint-config-prettier to disable formatting rules in ESLint. Let Prettier handle formatting and ESLint handle code quality.
  • Adopt ESLint 9 Flat Config (`eslint.config.js`) instead of `.eslintrc` for all new projects.
  • In monorepos (like Nx), keep a base configuration at the root and extend it in specific package directories.

Common Mistakes

  • Confusing `.eslintrc.json` syntax with the new Flat Config syntax (they are fundamentally different).
  • Running ESLint on build artifacts (forgetting to ignore `dist/` or `build/`).

Security Notes

  • Review third-party ESLint plugins before installing them. Supply chain attacks often target developer dependencies.
  • Never paste proprietary code into external tools. This generator runs entirely in your browser and does not collect your source code.

How We Keep Your Configs Safe & Valid

Built-in Error Checking

Every file is checked against official rules. We catch missing fields and bad syntax. YAML indentation errors are flagged right away. Kubernetes, Terraform, and Docker specs are all covered. API versions and labels are verified too. You get valid output every time you generate.

100% Private & Local

All tools run in your browser only. Your API keys never leave your machine. We do not use any tracking scripts. No data is sent to any server. Passwords and secrets stay on your device. Crypto operations use the Web Crypto API. Your privacy is fully protected at all times.

Secure Settings by Default

Configs use safe defaults out of the box. Containers run as non-root users. Root filesystems are set to read-only. Dangerous Linux capabilities are dropped. Network policies limit pod-to-pod traffic. TLS 1.3 is enabled for web servers. Security headers are added where needed.

Ready for CI/CD & Git

Output files are ready for your Git repo. Use them with ArgoCD, Flux, or GitHub Actions. Files use clear formatting and comments. Code review is easy for your team. Indentation and key order are consistent. Test in staging before going to production. Every file is clean and well-structured.

Infrastructure as Code

Store configs in Git alongside your code. Terraform modules include typed variables. Backend configs support remote state locking. Outputs work across multiple modules. Ansible playbooks use clear task steps. Chef and Puppet configs are also supported. Every file works with version control tools.

Monitoring & Tracing

Set up Prometheus with auto-discovery rules. Create Grafana dashboards with template variables. Add alerting rules with severity labels. Use OpenTelemetry for trace collection. Forward logs to Loki or Elasticsearch. Connect to Jaeger or Tempo for tracing. Monitor metrics, logs, and traces together.

Container & Docker Safety

Dockerfiles use multi-stage builds for small images. Base images are pinned to exact versions. Dev files are excluded from final images. Health checks are added for orchestrator use. Containers switch to non-root users. Docker Compose uses named volumes and networks. Resource limits are set in deploy configs.

Multiple Output Formats

Export as YAML, JSON, HCL, or TOML. Kubernetes uses YAML with proper separators. Terraform uses HCL with correct escaping. JSON output has consistent indentation. Copy to clipboard with one click. Preview output with syntax highlighting. Line numbers help you review quickly.
