v8.0.1

What's Changed

This release officially adds Node.js 26 support, with thanks to @​novemberborn in avajs/ava#3450.

Per our policy, support for Node.js 25 has been removed.

v8.0.0

Breaking Changes

AVA now expects Node.js 22.20, 24.12 or newer.

Internally AVA is now fully ESM. This is possible now that Node.js supports loading ES modules using require() calls and simplifies AVA's types and internals.

If you use AVA from a CommonJS project you'll have to update your imports:

-const test = require('ava');
+const {default: test} = require('ava');

We expect an increasing number of projects to be ESM only. As per the above, CommonJS is still supported, but we don't expect cjs extensions to be used. The default file extensions are now js and mjs. Specify extensions: ['cjs', 'js', 'mjs'] for AVA to run test files with the cjs extension.

All test files (and those loaded through AVA's require config) are now loaded via import(). Use customization hooks for transpilation. The object form of the extensions configuration is no longer supported.

If you use AVA with @​ava/typescript you must upgrade that package to v7.

New Features

There's two new test modifiers courtesy of @​sindresorhus: test.skipIf() to skip a test based on a runtime condition. test.runIf() is the inverse: the test only runs when the condition is true.

test.skipIf(process.platform === 'win32')('not on Windows', t => {
	t.pass();
});
test.runIf(process.platform === 'linux')('Linux only', t => {
t.pass();
});

These work with other modifiers like .serial and .failing:

test.serial.skipIf(process.platform === 'win32')('serial, not on Windows', t => {
	t.pass();
});

Breaking

• Requires Node.js 22
• Removed built-in React support.
  • Add eslint-config-xo-react to your config instead. Learn more
  • It was removed to keep XO's core lean and framework-agnostic. Bundling eslint-plugin-react for everyone held XO back by its slow ESLint-major support, and there's now a competing plugin, @eslint-react, so picking one for all users no longer makes sense.
• The bundled rules now live in a single eslint-config-xo package. The separate eslint-config-xo-typescript package is merged into it.
  • If you prefer using ESLint directly, you can get all the rules there now.
• Replaced the xoToEslintConfig export with the xo/eslint-adapter import for editor/ESLint integration. For example, xoToEslintConfig([{space: true, prettier: true}]) becomes eslintConfigXo({space: true, prettier: true}) from eslint-config-xo, or simply export {default} from 'xo/eslint-adapter';.

Improvements

• Lint CSS, Markdown, HTML, JSDoc comments, and regular expressions out of the box
• Add --max-warnings flag to treat warnings as errors (#724)
• Add ESLint bulk suppression support (#826)
• Hide warnings when there are errors, so you can focus on what matters (#507)
• Respect the global gitignore (#803)
• Allow overriding default ignores with negation patterns (#65)
• Throw when no files match explicitly provided patterns
