eslint-plugin-ava

library16.0.1jsnpmunverified

An ESLint plugin providing lint rules for the AVA test runner. Current stable version is 16.0.1, released in 2025. It requires Node.js >=20.19 and ESLint >=10 with flat config (ESM-only). Key differentiators: bundled with XO, dedicated to AVA's test API (macros, hooks, assertions), and includes rules like no-conditional-assertion and prefer-t-regex that are specific to AVA's assertion style. Release cadence is irregular with major versions tied to AVA/ESLint breaking changes.

flat config usage

✓ import eslintPluginAva from 'eslint-plugin-ava'; export default [{ plugins: { ava: eslintPluginAva }, rules: { 'ava/assertion-arguments': 'error' } }]

✗ module.exports = { plugins: ['ava'], rules: { 'ava/assertion-arguments': 'error' } }

Flat config is mandatory since v16.0.0; old .eslintrc style is not supported.

Minimal ESLint flat config for AVA rules using the recommended preset and custom overrides.

import eslintPluginAva from 'eslint-plugin-ava'; export default [ eslintPluginAva.configs.recommended, { rules: { 'ava/assertion-arguments': 'error', 'ava/no-only-test': 'error', }, }, ];
