ESLint + Prettier Addon

The ESLint + Prettier addon in Servest sets up both linting and formatting in your Node.js project, providing a consistent, error-free, and beautifully formatted codebase.

It installs recommended dependencies, creates configuration files, and updates your scripts for a combined workflow.

How It Works

When you run:

Loading code snippet…

Servest will:

1. Check the framework
   Ensures your project uses a supported Node.js framework. If not, the operation is canceled.

2. Detect whether your project uses JavaScript or TypeScript, and accordingly names the generated files with .js or .ts.

3. Install Required Packages using your selected package manager (npm, pnpm, yarn, or bun).

   Packages installed (with versions):

   • eslint@9.34.0
   • globals@16.3.0
   • @eslint/js@9.34.0
   • eslint-plugin-prettier@5.5.4
   • eslint-config-prettier@10.1.8
   • typescript-eslint@8.41.0 (only if project language is TypeScript)

4. Create ESLint Configuration

   • Generates .eslintrc.js or .eslintrc.ts depending on your language.
   • Adds recommended rules and integrates the Prettier plugin.

5. Create Prettier Configuration

   • Generates .prettierrc and .prettierignore files if they don’t exist.

6. Update package.json Scripts
   Adds or preserves the following scripts:

This gives you a ready-to-use linting and formatting setup without manually installing packages or creating config files.

Notes

• ESLint + Prettier can be safely re-run — existing configurations and scripts are preserved.
• Works seamlessly with other Servest addons.
• Confirmation Messages:
  • ✅ Shows when configuration and scripts are successfully added.
  • 👍 Appears if ESLint & Prettier are already installed.
  • 🎉 Confirms successful setup.

Why Use ESLint + Prettier?

• Consistency → ensures coding standards and formatting are followed across the project.
• Error prevention → detects potential bugs before runtime.
• Integration-friendly → works well with other Servest addons like lint-staged.
• Safe to re-run → won’t overwrite existing setup, avoiding accidental data loss.
