eslint-config-trendmicro [](http://badge.fury.io/js/eslint-config-trendmicro) [](https://travis-ci.org/trendmicro-frontend/eslint-config-trendmicro)

This package provides an ESLint flat config as an extensible shared configuration.

Note: v4+ requires ESLint v9 and uses the flat config format (eslint.config.js). For ESLint v7/v8 with .eslintrc, use v3.x.

Requirements

• Node.js >= 20
• ESLint >= 9

Usage

1. Install the latest version of eslint-config-trendmicro:

npm install --save-dev eslint-config-trendmicro@latest

2. Install the required peer dependencies:

npm install --save-dev eslint eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks

3. Create an eslint.config.js (or eslint.config.mjs) in your project root:

ESM (eslint.config.js with "type": "module" in package.json, or eslint.config.mjs):

import trendmicroConfig from 'eslint-config-trendmicro';

export default [
  ...trendmicroConfig,
  {
    // your project-specific overrides
    rules: {},
  },
];

CommonJS (eslint.config.cjs):

const trendmicroConfig = require('eslint-config-trendmicro');

module.exports = [
  ...trendmicroConfig,
  {
    // your project-specific overrides
    rules: {},
  },
];

Customizing Language Options

You can override languageOptions for your environment:

import trendmicroConfig from 'eslint-config-trendmicro';
import globals from 'globals';

export default [
  ...trendmicroConfig,
  {
    languageOptions: {
      globals: {
        ...globals.browser,
        ...globals.node,
      },
    },
    rules: {
      // your overrides
    },
  },
];

Using with a Custom Parser (e.g. Babel)

import trendmicroConfig from 'eslint-config-trendmicro';
import babelParser from '@babel/eslint-parser';

export default [
  ...trendmicroConfig,
  {
    languageOptions: {
      parser: babelParser,
      parserOptions: {
        requireConfigFile: false,
        babelOptions: {
          presets: ['@babel/preset-react'],
        },
      },
    },
  },
];

Migrating from v3.x (ESLint v7/v8)

Replace your .eslintrc / .eslintrc.json with an eslint.config.js:

Before (v3.x, .eslintrc):

{
  "extends": "trendmicro",
  "parser": "@babel/eslint-parser",
  "env": {
    "browser": true,
    "node": true
  },
  "plugins": ["@babel"],
  "rules": {}
}

After (v4.x, eslint.config.js):

import trendmicroConfig from 'eslint-config-trendmicro';
import globals from 'globals';

export default [
  ...trendmicroConfig,
  {
    languageOptions: {
      globals: {
        ...globals.browser,
        ...globals.node,
      },
    },
    rules: {},
  },
];
