Release Notes

cosmiconfig/cosmiconfig

### [`v8.2.0`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​820) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v8.1.3...v8.2.0) - Add support for ECMAScript modules (ESM) to the [*asynchronous* API](./README.md#asynchronous-api). End users running Node versions that support ESM can provide `.mjs` files, or `.js` files whose nearest parent `package.json` file contains `"type": "module"`. - `${moduleName}rc.mjs` and `${moduleName}.config.mjs` are included in the default `searchPlaces` of the asynchronous API. - The [synchronous API](./README.md#synchronous-api) does not support ECMAScript modules, so does not look for `.mjs` files. - To learn more, read ["Loading JS modules"](./README.md#loading-js-modules). ### [`v8.1.3`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​813) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v8.1.2...v8.1.3) - Fixed: existence of meta config breaking default loaders ### [`v8.1.2`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​812) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v8.1.1...v8.1.2) - Fixed: generation of TypeScript types going to the wrong output path ### [`v8.1.1`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​811) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v8.1.0...v8.1.1) - Fixed: meta config overriding original options completely (now merges correctly) ### [`v8.1.0`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​810) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v8.0.0...v8.1.0) - Added: always look at `.config.{yml,yaml,json,js,cjs}` file to configure cosmiconfig itself, and look for tool configuration in it using `packageProp` (similar to package.json) - For more info on this, look at the [end user configuration section of the README](README.md#usage-for-end-users) ### [`v8.0.0`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​800) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v7.1.0...v8.0.0) **No major breaking changes!** We dropped support for Node 10 and 12 -- which you're probably not using. And we swapped out the YAML parser -- which you probably won't notice. - **Breaking change:** Drop support for Node 10 and 12. - **Breaking change:** Use npm package [js-yaml](https://www.npmjs.com/package/js-yaml) to parse YAML instead of npm package [yaml](https://www.npmjs.com/package/yaml). - Added: Loader errors now include the path of the file that was tried to be loaded. ### [`v7.1.0`](https://togithub.com/cosmiconfig/cosmiconfig/blob/HEAD/CHANGELOG.md#​710) [Compare Source](https://togithub.com/cosmiconfig/cosmiconfig/compare/v7.0.1...v7.1.0) - Added: Additional default `searchPlaces` within a .config subdirectory (without leading dot in the file name)
