+
+Cosmiconfig searches for and loads configuration for your program.
+
+It features smart defaults based on conventional expectations in the JavaScript ecosystem.
+But it's also flexible enough to search wherever you'd like to search, and load whatever you'd like to load.
+
+By default, Cosmiconfig will start where you tell it to start and search up the directory tree for the following:
+
+- a `package.json` property
+- a JSON or YAML, extensionless "rc file"
+- an "rc file" with the extensions `.json`, `.yaml`, `.yml`, `.js`, or `.cjs`
+- any of the above two inside a `.config` subdirectory
+- a `.config.js` or `.config.cjs` CommonJS module
+
+For example, if your module's name is "myapp", cosmiconfig will search up the directory tree for configuration in the following places:
+
+- a `myapp` property in `package.json`
+- a `.myapprc` file in JSON or YAML format
+- a `.myapprc.json`, `.myapprc.yaml`, `.myapprc.yml`, `.myapprc.js`, or `.myapprc.cjs` file
+- a `myapprc`, `myapprc.json`, `myapprc.yaml`, `myapprc.yml`, `myapprc.js` or `myapprc.cjs` file inside a `.config` subdirectory`
+- a `myapp.config.js` or `myapp.config.cjs` CommonJS module exporting an object
+
+Cosmiconfig continues to search up the directory tree, checking each of these places in each directory, until it finds some acceptable configuration (or hits the home directory).

+## Installation
+
+```
+npm install cosmiconfig
+```
+
+Tested in Node 10+.
+
+## Usage
+
+Create a Cosmiconfig explorer, then either `search` for or directly `load` a configuration file.
+
+```js
+const { cosmiconfig, cosmiconfigSync } = require('cosmiconfig');
+// ...
+const explorer = cosmiconfig(moduleName);
+
+// Search for a configuration by walking up directories.
+// See documentation for search, below.
+explorer.search()
+  .then((result) => {
+    // result.config is the parsed configuration object.
+    // result.filepath is the path to the config file that was found.
+    // result.isEmpty is true if there was nothing to parse in the config file.
+  })
+  .catch((error) => {
+    // Do something constructive.
+  });
+
+// Load a configuration directly when you know where it should be.
+// The result object is the same as for search.
+// See documentation for load, below.
+explorer.load(pathToConfig).then(..);
+
+// You can also search and load synchronously.
+const explorerSync = cosmiconfigSync(moduleName);
+
+const searchedFor = explorerSync.search();
+const loaded = explorerSync.load(pathToConfig);
+```
+
+## Result
+
+The result object you get from `search` or `load` has the following properties:
+
+- **config:** The parsed configuration object. `undefined` if the file is empty.
+- **filepath:** The path to the configuration file that was found.
+- **isEmpty:** `true` if the configuration file is empty. This property will not be present if the configuration file is not empty.
+
+## Asynchronous API
+
+### cosmiconfig()
+
+```js
+const { cosmiconfig } = require('cosmiconfig');
+const explorer = cosmiconfig(moduleName[, cosmiconfigOptions])
+```
+
+Creates a cosmiconfig instance ("explorer") configured according to the arguments, and initializes its caches.
+
+#### moduleName
+
+Type: `string`. **Required.**
+
+Your module name. This is used to create the default [`searchPlaces`] and [`packageProp`].
+
+If your [`searchPlaces`] value will include files, as it does by default (e.g. `${moduleName}rc`), your `moduleName` must consist of characters allowed in filenames. That means you should not copy scoped package names, such as `@my-org/my-package`, directly into `moduleName`.
+
+**[`cosmiconfigOptions`] are documented below.**
+You may not need them, and should first read about the functions you'll use.
+
+### explorer.search()
+
+```js
+explorer.search([searchFrom]).then(result => {..})
+```
+
+Searches for a configuration file. Returns a Promise that resolves with a [result] or with `null`, if no configuration file is found.
+
+You can do the same thing synchronously with [`explorerSync.search()`].
+
+Let's say your module name is `goldengrahams` so you initialized with `const explorer = cosmiconfig('goldengrahams');`.
+Here's how your default [`search()`] will work:
+
+- Starting from `process.cwd()` (or some other directory defined by the `searchFrom` argument to [`search()`]), look for configuration objects in the following places:
+  1. A `goldengrahams` property in a `package.json` file.
+  2. A `.goldengrahamsrc` file with JSON or YAML syntax.
+  3. A `.goldengrahamsrc.json`, `.goldengrahamsrc.yaml`, `.goldengrahamsrc.yml`, `.goldengrahamsrc.js`, or `.goldengrahamsrc.cjs` file.
+  4. A `goldengrahamsrc`, `goldengrahamsrc.json`, `goldengrahamsrc.yaml`, `goldengrahamsrc.yml`, `goldengrahamsrc.js`, or `goldengrahamsrc.cjs` file in the `.config` subdirectory.
+  5. A `goldengrahams.config.js` or `goldengrahams.config.cjs` CommonJS module exporting the object.
+- If none of those searches reveal a configuration object, move up one directory level and try again.
+  So the search continues in `./`, `../`, `../../`, `../../../`, etc., checking the same places in each directory.
+- Continue searching until arriving at your home directory (or some other directory defined by the cosmiconfig option [`stopDir`]).
+- If at any point a parsable configuration is found, the [`search()`] Promise resolves with its [result] \(or, with [`explorerSync.search()`], the [result] is returned).
+- If no configuration object is found, the [`search()`] Promise resolves with `null` (or, with [`explorerSync.search()`], `null` is returned).
+- If a configuration object is found *but is malformed* (causing a parsing error), the [`search()`] Promise rejects with that error (so you should `.catch()` it). (Or, with [`explorerSync.search()`], the error is thrown.)
+
+**If you know exactly where your configuration file should be, you can use [`load()`], instead.**
+
+**The search process is highly customizable.**
+Use the cosmiconfig options [`searchPlaces`] and [`loaders`] to precisely define where you want to look for configurations and how you want to load them.
+
+#### searchFrom
+
+Type: `string`.
+Default: `process.cwd()`.
+
+A filename.
+[`search()`] will start its search here.
+
+If the value is a directory, that's where the search starts.
+If it's a file, the search starts in that file's directory.
+
+### explorer.load()
+
+```js
+explorer.load(loadPath).then(result => {..})
+```
+
+Loads a configuration file. Returns a Promise that resolves with a [result] or rejects with an error (if the file does not exist or cannot be loaded).
+
+Use `load` if you already know where the configuration file is and you just need to load it.
+
+```js
+explorer.load('load/this/file.json'); // Tries to load load/this/file.json.
+```
+
+If you load a `package.json` file, the result will be derived from whatever property is specified as your [`packageProp`].
+
+You can do the same thing synchronously with [`explorerSync.load()`].
+
+### explorer.clearLoadCache()
+
+Clears the cache used in [`load()`].
+
+### explorer.clearSearchCache()
+
+Clears the cache used in [`search()`].
+
+### explorer.clearCaches()
+
+Performs both [`clearLoadCache()`] and [`clearSearchCache()`].
+
+## Synchronous API
+
+### cosmiconfigSync()
+
+```js
+const { cosmiconfigSync } = require('cosmiconfig');
+const explorerSync = cosmiconfigSync(moduleName[, cosmiconfigOptions])
+```
+
+Creates a *synchronous* cosmiconfig instance ("explorerSync") configured according to the arguments, and initializes its caches.
+
+See [`cosmiconfig()`].
+
+### explorerSync.search()
+
+```js
+const result = explorerSync.search([searchFrom]);
+```
+
+Synchronous version of [`explorer.search()`].
+
+Returns a [result] or `null`.
+
+### explorerSync.load()
+
+```js
+const result = explorerSync.load(loadPath);
+```
+
+Synchronous version of [`explorer.load()`].
+
+Returns a [result].
+
+### explorerSync.clearLoadCache()
+
+Clears the cache used in [`load()`].
+
+### explorerSync.clearSearchCache()
+
+Clears the cache used in [`search()`].
+
+### explorerSync.clearCaches()
+
+Performs both [`clearLoadCache()`] and [`clearSearchCache()`].
+
+## cosmiconfigOptions
+
+Type: `Object`.
+
+Possible options are documented below.
+
+### searchPlaces
+
+Type: `Array<string>`.
+Default: See below.
+
+An array of places that [`search()`] will check in each directory as it moves up the directory tree.
+Each place is relative to the directory being searched, and the places are checked in the specified order.
+
+**Default `searchPlaces`:**
+
+```js
+[
+  'package.json',
+  `.${moduleName}rc`,
+  `.${moduleName}rc.json`,
+  `.${moduleName}rc.yaml`,
+  `.${moduleName}rc.yml`,
+  `.${moduleName}rc.js`,
+  `.${moduleName}rc.cjs`,
+  `.config/${moduleName}rc`,
+  `.config/${moduleName}rc.json`,
+  `.config/${moduleName}rc.yaml`,
+  `.config/${moduleName}rc.yml`,
+  `.config/${moduleName}rc.js`,
+  `.config/${moduleName}rc.cjs`,
+  `${moduleName}.config.js`,
+  `${moduleName}.config.cjs`,
+]
+```
+
+Create your own array to search more, fewer, or altogether different places.
+
+Every item in `searchPlaces` needs to have a loader in [`loaders`] that corresponds to its extension.
+(Common extensions are covered by default loaders.)
+Read more about [`loaders`] below.
+
+`package.json` is a special value: When it is included in `searchPlaces`, Cosmiconfig will always parse it as JSON and load a property within it, not the whole file.
+That property is defined with the [`packageProp`] option, and defaults to your module name.
+
+Examples, with a module named `porgy`:
+
+```js
+// Disallow extensions on rc files:
+[
+  'package.json',
+  '.porgyrc',
+  'porgy.config.js'
+]
+
+// ESLint searches for configuration in these places:
+[
+  '.eslintrc.js',
+  '.eslintrc.yaml',
+  '.eslintrc.yml',
+  '.eslintrc.json',
+  '.eslintrc',
+  'package.json'
+]
+
+// Babel looks in fewer places:
+[
+  'package.json',
+  '.babelrc'
+]
+
+// Maybe you want to look for a wide variety of JS flavors:
+[
+  'porgy.config.js',
+  'porgy.config.mjs',
+  'porgy.config.ts',
+  'porgy.config.coffee'
+]
+// ^^ You will need to designate custom loaders to tell
+// Cosmiconfig how to handle these special JS flavors.
+
+// Look within a .config/ subdirectory of every searched directory:
+[
+  'package.json',
+  '.porgyrc',
+  '.config/.porgyrc',
+  '.porgyrc.json',
+  '.config/.porgyrc.json'
+]
+```
+
+### loaders
+
+Type: `Object`.
+Default: See below.
+
+An object that maps extensions to the loader functions responsible for loading and parsing files with those extensions.
+
+Cosmiconfig exposes its default loaders on a named export `defaultLoaders`.
+
+**Default `loaders`:**
+
+```js
+const { defaultLoaders } = require('cosmiconfig');
+
+console.log(Object.entries(defaultLoaders))
+// [
+//   [ '.cjs', [Function: loadJs] ],
+//   [ '.js', [Function: loadJs] ],
+//   [ '.json', [Function: loadJson] ],
+//   [ '.yaml', [Function: loadYaml] ],
+//   [ '.yml', [Function: loadYaml] ],
+//   [ 'noExt', [Function: loadYaml] ]
+// ]
+```
+
+(YAML is a superset of JSON; which means YAML parsers can parse JSON; which is how extensionless files can be either YAML *or* JSON with only one parser.)
+
+**If you provide a `loaders` object, your object will be *merged* with the defaults.**
+So you can override one or two without having to override them all.
+
+**Keys in `loaders`** are extensions (starting with a period), or `noExt` to specify the loader for files *without* extensions, like `.myapprc`.
+
+**Values in `loaders`** are a loader function (described below) whose values are loader functions.
+
+**The most common use case for custom loaders value is to load extensionless `rc` files as strict JSON**, instead of JSON *or* YAML (the default).
+To accomplish that, provide the following `loaders` value:
+
+```js
+{
+  noExt: defaultLoaders['.json']
+}
+```
+
+If you want to load files that are not handled by the loader functions Cosmiconfig exposes, you can write a custom loader function or use one from NPM if it exists.
+
+**Third-party loaders:**
+
+- [cosmiconfig-typescript-loader](https://github.com/codex-/cosmiconfig-typescript-loader)
+
+**Use cases for custom loader function:**
+
+- Allow configuration syntaxes that aren't handled by Cosmiconfig's defaults, like JSON5, INI, or XML.
+- Allow ES2015 modules from `.mjs` configuration files.
+- Parse JS files with Babel before deriving the configuration.
+
+**Custom loader functions** have the following signature:
+
+```js
+// Sync
+(filepath: string, content: string) => Object | null
+
+// Async
+(filepath: string, content: string) => Object | null | Promise<Object | null>
+```
+
+Cosmiconfig reads the file when it checks whether the file exists, so it will provide you with both the file's path and its content.
+Do whatever you need to, and return either a configuration object or `null` (or, for async-only loaders, a Promise that resolves with one of those).
+`null` indicates that no real configuration was found and the search should continue.
+
+A few things to note:
+
+- If you use a custom loader, be aware of whether it's sync or async: you cannot use async customer loaders with the sync API ([`cosmiconfigSync()`]).
+- **Special JS syntax can also be handled by using a `require` hook**, because `defaultLoaders['.js']` just uses `require`.
+  Whether you use custom loaders or a `require` hook is up to you.
+
+Examples:
+
+```js
+// Allow JSON5 syntax:
+{
+  '.json': json5Loader
+}
+
+// Allow a special configuration syntax of your own creation:
+{
+  '.special': specialLoader
+}
+
+// Allow many flavors of JS, using custom loaders:
+{
+  '.mjs': esmLoader,
+  '.ts': typeScriptLoader,
+  '.coffee': coffeeScriptLoader
+}
+
+// Allow many flavors of JS but rely on require hooks:
+{
+  '.mjs': defaultLoaders['.js'],
+  '.ts': defaultLoaders['.js'],
+  '.coffee': defaultLoaders['.js']
+}
+```
+
+### packageProp
+
+Type: `string | Array<string>`.
+Default: `` `${moduleName}` ``.
+
+Name of the property in `package.json` to look for.
+
+Use a period-delimited string or an array of strings to describe a path to nested properties.
+
+For example, the value `'configs.myPackage'` or `['configs', 'myPackage']` will get you the `"myPackage"` value in a `package.json` like this:
+
+```json
+{
+  "configs": {
+    "myPackage": {..}
+  }
+}
+```
+
+If nested property names within the path include periods, you need to use an array of strings. For example, the value `['configs', 'foo.bar', 'baz']` will get you the `"baz"` value in a `package.json` like this:
+
+```json
+{
+  "configs": {
+    "foo.bar": {
+      "baz": {..}
+    }
+  }
+}
+```
+
+If a string includes period but corresponds to a top-level property name, it will not be interpreted as a period-delimited path. For example, the value `'one.two'` will get you the `"three"` value in a `package.json` like this:
+
+```json
+{
+  "one.two": "three",
+  "one": {
+    "two": "four"
+  }
+}
+```
+
+### stopDir
+
+Type: `string`.
+Default: Absolute path to your home directory.
+
+Directory where the search will stop.
+
+### cache
+
+Type: `boolean`.
+Default: `true`.
+
+If `false`, no caches will be used.
+Read more about ["Caching"](#caching) below.
+
+### transform
+
+Type: `(Result) => Promise<Result> | Result`.
+
+A function that transforms the parsed configuration. Receives the [result].
+
+If using [`search()`] or [`load()`] \(which are async), the transform function can return the transformed result or return a Promise that resolves with the transformed result.
+If using `cosmiconfigSync`, [`search()`] or [`load()`], the function must be synchronous and return the transformed result.
+
+The reason you might use this option — instead of simply applying your transform function some other way — is that *the transformed result will be cached*. If your transformation involves additional filesystem I/O or other potentially slow processing, you can use this option to avoid repeating those steps every time a given configuration is searched or loaded.
+
+### ignoreEmptySearchPlaces
+
+Type: `boolean`.
+Default: `true`.
+
+By default, if [`search()`] encounters an empty file (containing nothing but whitespace) in one of the [`searchPlaces`], it will ignore the empty file and move on.
+If you'd like to load empty configuration files, instead, set this option to `false`.
+
+Why might you want to load empty configuration files?
+If you want to throw an error, or if an empty configuration file means something to your program.
+
+## Caching
+
+As of v2, cosmiconfig uses caching to reduce the need for repetitious reading of the filesystem or expensive transforms. Every new cosmiconfig instance (created with `cosmiconfig()`) has its own caches.
+
+To avoid or work around caching, you can do the following:
+
+- Set the `cosmiconfig` option [`cache`] to `false`.
+- Use the cache-clearing methods [`clearLoadCache()`], [`clearSearchCache()`], and [`clearCaches()`].
+- Create separate instances of cosmiconfig (separate "explorers").
+
+## Differences from [rc](https://github.com/dominictarr/rc)
+
+[rc](https://github.com/dominictarr/rc) serves its focused purpose well. cosmiconfig differs in a few key ways — making it more useful for some projects, less useful for others:
+
+- Looks for configuration in some different places: in a `package.json` property, an rc file, a `.config.js` file, and rc files with extensions.
+- Built-in support for JSON, YAML, and CommonJS formats.
+- Stops at the first configuration found, instead of finding all that can be found up the directory tree and merging them automatically.
+- Options.
+- Asynchronous by default (though can be run synchronously).
