Prettier Config Generator

Generate Prettier config files with formatting options, ESLint integration, EditorConfig, line endings, WebStorm setup, XML, YAML, and TypeScript.

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

Core Formatting

Wrap lines that exceed this length (default: 80).

Number of spaces per indentation level.

- Indent lines with tabs instead of spaces.
- Print semicolons at the ends of statements.

Quotes & Commas

- Use single quotes instead of double quotes.
- Use single quotes in JSX attributes.

Brackets & Parens

- Print spaces between brackets in object literals.
- Put the `>` of a multi-line HTML/JSX element at the end of the last line.

Plugins & Workflow

- Automatically sort Tailwind classes.
- Sort imports via @trivago/prettier-plugin-sort-imports.

Files and directories to ignore.

What is this tool?

Prettier Config Generator is a tool that allows you to visually build formatting configurations for your entire engineering team. It outputs formats like `.prettierrc`, `prettier.config.js`, `.prettierignore`, and `.editorconfig` to enforce strict style guidelines across codebases and IDEs.

How to Use This Tool

  1. Adjust the formatting rules (Print Width, Tab Width, Quotes, Semicolons).
  2. Select line ending rules (e.g., enforcing LF for cross-platform teams).
  3. Enable advanced integrations (Tailwind sorting, EditorConfig generation).
  4. Review the generated `.prettierrc` output in the editor panel.
  5. Copy the files into the root directory of your project.

What This Tool Generates

  • .prettierrc or prettier.config.js
  • .prettierignore to exclude build artifacts
  • .editorconfig to synchronize IDE settings with Prettier
  • package.json dependency installation commands

Enterprise Best Practices

  • Generate EditorConfig from Prettier: Keep your Prettier rules and `.editorconfig` in sync so WebStorm and VS Code developers get formatting assistance before they even save the file.
  • Prettier config per project: In monorepos, you can place a root `.prettierrc` and override specific rules in subdirectories using nested configs.
  • Enforce LF Line Endings: Always enforce `lf` to prevent massive Windows/Mac Git diffs where every line is marked as changed.

Common Mistakes

  • Trying to use Prettier to fix code quality issues. Prettier ONLY handles formatting. Use ESLint for logic bugs.
  • Not adding `.prettierignore` and accidentally formatting `dist/`, `.next/`, or `node_modules/`.

Security Notes

  • Formatting tools do not execute your application code, but running third-party Prettier plugins (like Tailwind sorters) does execute plugin code. Ensure plugins come from trusted npm sources.
  • Do not paste proprietary code into external formatting tools. This generator runs entirely in your browser.

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.
