flat

Bug Fixes 🐛

• Fix misformatted export field in package.json (see #172).

New Features ✨

• Package is now distributed in the ECMAScript module syntax (see #149).
• Definitions for TypeScript are now included out of the box (see #151).

Breaking Changes 💥

• Support for all module formats besides ECMAScript modules has been dropped.
• Default export has been dropped in favor of a named one.
• Officially supported Node.js version is now 18 and up (all others are end-of-life).

Migration 🚚

We are now shipping flat as a pure ECMAScript module, if you are still using CommonJS in your application follow this migration guide.

The default export has been dropped in favor of a named one, if you are using the default export make sure to update your imports:

-import flatten from 'flat'
+import { flatten } from 'flat'

If you are a user of TypeScript you can remove @types/flat from your project. The type definitions are now included in the package itself, so it is no longer required to keep a separate dependency around.

npm uninstall @types/flat
