eslint-config-twilio

library2.0.0jsnpmunverified

Twilio's official ESLint shareable config enforcing JavaScript style guidelines. Current stable version 2.0.0 requires ESLint ^8 and drops support for ESLint 5, 6, and 7. Integrates with prettier, eslint-plugin-import, eslint-plugin-no-only-tests, and eslint-plugin-sonarjs. Designed for Twilio's codebase but usable by any JavaScript project. Released under twilio-style monorepo with slow cadence; no known further updates.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

extends config

✓ { "extends": ["twilio"] }

✗ { "extends": ["eslint-config-twilio"] }

Use the shorthand 'twilio' in extends, not the full package name.

prettier config import (CommonJS)

✓ const baseConfig = require('./node_modules/eslint-config-twilio/rules/prettier');

✗ import baseConfig from 'eslint-config-twilio/rules/prettier';

The rules/prettier file is CommonJS; ESM import may fail in some environments.

prettier config import (ESM)

✓ import { createRequire } from 'module'; const require = createRequire(import.meta.url); const baseConfig = require('./node_modules/eslint-config-twilio/rules/prettier');

✗ import baseConfig from 'eslint-config-twilio/rules/prettier';

Use createRequire to load CommonJS module from ESM.

Installs eslint@^8 and eslint-config-twilio, configures ESLint with the twilio preset, and sets up lint and lint:fix scripts.

// Install npm install eslint@^8 eslint-config-twilio --save-dev // .eslintrc.json { "extends": ["twilio"] } // package.json scripts { "scripts": { "lint": "eslint --ext js src/", "lint:fix": "npm run lint -- --fix" } } // Example usage npx eslint src/

Debug

Known issues

breakingDropped support for ESLint 5, 6, and 7. Only ESLint ^8 is supported.

fix

Upgrade ESLint to version 8 or later.

affects: >=1.0.0 <2.0.0

gotchaYou must install peer dependency eslint@^8 manually; npm<7 does not auto-install peer deps.

fix

Run 'npm install eslint@^8 --save-dev' if not already installed, or upgrade npm to >=7.

affects: >=2.0.0

gotchaThe prettier rules are not applied unless you extend 'twilio'. Overriding prettier/prettier rules requires additional configuration.

fix

Follow the Prettier section in README to customize: add override rule 'prettier/prettier': ['warn', {}, { 'usePrettierrc': true }]

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'eslint-config-twilio'

Package not installed or not in node_modules.

fix

Run 'npm install eslint eslint-config-twilio --save-dev'.

Error: Failed to load plugin 'import' declared in 'BaseConfig': Cannot find module 'eslint-plugin-import'

Peer dependencies (including eslint-plugin-import) are not installed automatically.

fix

Install missing peer dependencies: 'npm install eslint-plugin-import --save-dev'.

Error: ESLint configuration in .eslintrc.json is invalid: Unexpected top-level property "extends"

Using an invalid ESLint config file format (e.g., missing JSON quotes or using JavaScript object).

Ensure .eslintrc.json is valid JSON with double-quoted strings.
