Usage

This project now uses only "flat config". An "eslint.config.js" file in the project root directory is required.

Note: According to different "type" setting in package.json, the different file format (CommonJS / Module) will be required.

// Example eslint.config.js
import {generateConfig} from '@dwzq/eslint-config'


export default await generateConfig({
  type: 'node',
  ts  : {
    rootDir: import.meta.dirname,
  },
})

Check type declaration in source code for options.
