5. Once the installation completes, the server should start automatically and provide ESLint language support (autocomplete, diagnostics, etc.).

Step 2: Configure ESLint

• Execute npm install eslint in your project root
• Create an eslint-config.js file on your root project like this:

export default [
 {
   files: ['**/*.js'],
   languageOptions: {
     ecmaVersion: 'latest',
     sourceType: 'module',
   },
   rules: {
     'no-console': 'error',
   },
 },
];

• Create a test.js file like this:

const s = "foo";
console.log(s);

You should see an eslint error on console.
