Shared configuration for ESLint, TypeScript, and Prettier used across Lasercat projects.

Installation

npm install --save-dev @lasercat/config

Usage

ESLint

Create an eslint.config.js file in your project:

import baseConfig from '@lasercat/config/eslint.config.js';

export default [
  ...baseConfig,
  // Your custom rules here
];

TypeScript

Create a tsconfig.json file in your project:

  "extends": "@lasercat/config/tsconfig.json",
  "compilerOptions": {
    // Your custom options here
  },
  "include": ["src"],
  "exclude": ["node_modules", "dist"]

  "compilerOptions": {
    // Your custom build options here
  }
}

Create a .prettierrc.json file in your project:

{
  "extends": "@lasercat/config/.prettierrc.json"

Or in your package.json:

{
  "prettier": "@lasercat/config/.prettierrc.json"
}
