Breaking change: The package now has named exports. See examples below.

Breaking change: Separate async and sync APIs, accessible from different named exports. If you used explorer.searchSync() or explorer.loadSync(), you'll now create a sync explorer with cosmiconfigSync(), then use explorerSync.search() and explorerSync.load().

// OLD: cosmiconfig v5
import cosmiconfig from 'cosmiconfig';

const explorer = cosmiconfig('example');
const searchAsyncResult = await explorer.search();
const loadAsyncResult = await explorer.load('./file/to/load');
const searchSyncResult = explorer.searchSync();
const loadSyncResult = explorer.loadSync('./file/to/load');

// NEW: cosmiconfig v6
import { cosmiconfig, cosmiconfigSync } from 'cosmiconfig';

const explorer = cosmiconfig('example');
const searchAsyncResult = await explorer.search();
const loadAsyncResult = await explorer.load('./file/to/load');

const explorerSync = cosmiconfigSync('example');
const searchSyncResult = explorerSync.search();
const loadSyncResult = explorerSync.load('./file/to/load');

Breaking change: Remove support for Node 4 and 6. Requires Node 8+.

Breaking change: Use npm package yaml to parse YAML instead of npm package js-yaml.

Breaking change: Remove cosmiconfig.loaders and add named export defaultLoaders that exports the default loaders used for each extension.

import { defaultLoaders } from 'cosmiconfig';

console.log(Object.entries(defaultLoaders));
// [
//   [ '.js', [Function: loadJs] ],
//   [ '.json', [Function: loadJson] ],
//   [ '.yaml', [Function: loadYaml] ],
//   [ '.yml', [Function: loadYaml] ],
//   [ 'noExt', [Function: loadYaml] ]
// ]

Migrate from Flowtype to Typescript.

Lazy load all default loaders.
