@splunk/eslint-config

This package provides extendable ESLint configuration objects. Currently, the following configs are available:

Available configs

Requires Babel:

• browser - For code that runs in the browser.
• browser-prettier - For browser code that is formatted by prettier.
• node - For node scripts.
• node-prettier - For node scripts that are automatically formatted with prettier.

Does not require Babel - use these if your build tool handles JSX natively:

• flat-browser - For modern toolchains (Vite + SWC, etc.) without Babel.
• flat-browser-prettier - For browser code with modern toolchains, formatted with prettier.

Install

1. Install the package and its required peers:

   npm install --save-dev @splunk/eslint-config eslint@^9 @eslint/js@^9

2. If you are using the Babel-based configs, also install:

   npm install --save-dev @babel/core@^7 @babel/eslint-parser@^7

Usage

CommonJS flat config

Use the CommonJS entrypoints from eslint.config.cjs when you want the Babel-based browser config or the node configs.

const { defineConfig } = require('eslint/config');
const browser = require('@splunk/eslint-config/browser');

module.exports = defineConfig(browser, {
    // Your additional configuration
});

const { defineConfig } = require('eslint/config');
const browserPrettier = require('@splunk/eslint-config/browser-prettier');

module.exports = defineConfig(browserPrettier, {
    // Your additional configuration
});

const { defineConfig } = require('eslint/config');
const node = require('@splunk/eslint-config/node');

module.exports = defineConfig(node, {
    // Your additional configuration
});

const { defineConfig } = require('eslint/config');
const nodePrettier = require('@splunk/eslint-config/node-prettier');

module.exports = defineConfig(nodePrettier, {
    // Your additional configuration
});

ESM Babel-free browser config

Use the flat-browser entrypoints from eslint.config.js / eslint.config.mjs when your toolchain handles JSX without Babel.

import splunkConfig from '@splunk/eslint-config/flat-browser.mjs';

export default [
    ...splunkConfig,
    // Your additional configuration
];

import splunkConfig from '@splunk/eslint-config/flat-browser-prettier.mjs';

export default [
    ...splunkConfig,
    // Your additional configuration
];
