+```
+
+
+## API
+
+### findUp(name, options?)
+### findUp(matcher, options?)
+
+Returns a `Promise` for either the path or `undefined` if it couldn't be found.
+
+### findUp([...name], options?)
+
+Returns a `Promise` for either the first path found (by respecting the order of the array) or `undefined` if none could be found.
+
+### findUp.sync(name, options?)
+### findUp.sync(matcher, options?)
+
+Returns a path or `undefined` if it couldn't be found.
+
+### findUp.sync([...name], options?)
+
+Returns the first path found (by respecting the order of the array) or `undefined` if none could be found.
+
+#### name
+
+Type: `string`
+
+Name of the file or directory to find.
+
+#### matcher
+
+Type: `Function`
+
+A function that will be called with each directory until it returns a `string` with the path, which stops the search, or the root directory has been reached and nothing was found. Useful if you want to match files with certain patterns, set of permissions, or other advanced use-cases.
+
+When using async mode, the `matcher` may optionally be an async or promise-returning function that returns the path.
+
+#### options
+
+Type: `object`
+
+##### cwd
+
+Type: `string`<br>
+Default: `process.cwd()`
+
+Directory to start from.
+
+##### type
+
+Type: `string`<br>
+Default: `'file'`<br>
+Values: `'file'` `'directory'`
+
+The type of paths that can match.
+
+##### allowSymlinks
+
+Type: `boolean`<br>
+Default: `true`
+
+Allow symbolic links to match if they point to the chosen path type.
+
+### findUp.exists(path)
+
+Returns a `Promise<boolean>` of whether the path exists.
+
+### findUp.sync.exists(path)
+
+Returns a `boolean` of whether the path exists.
+
+#### path
+
+Type: `string`
+
+Path to a file or directory.
+
+### findUp.stop
+
+A [`Symbol`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol) that can be returned by a `matcher` function to stop the search and cause `findUp` to immediately return `undefined`. Useful as a performance optimization in case the current working directory is deeply nested in the filesystem.
+
+```js
+const path = require('path');
+const findUp = require('find-up');
+
+(async () => {
+	await findUp(directory => {
+		return path.basename(directory) === 'work' ? findUp.stop : 'logo.png';
+	});
+})();

+
+> Run multiple promise-returning & async functions with limited concurrency
+
+## Install
+
+```
+$ npm install p-limit
+```
+
+## Usage
+
+```js
+const pLimit = require('p-limit');
+
+const limit = pLimit(1);

+	limit(() => fetchSomething('bar')),
+	limit(() => doSomething())
+];
+
+(async () => {
+	// Only one promise is run at once
+	const result = await Promise.all(input);
+	console.log(result);
+})();
+```
+
+## API
+
+### pLimit(concurrency)
+
+Returns a `limit` function.
+
+#### concurrency
+
+Type: `number`\
+Minimum: `1`\
+Default: `Infinity`
+
+Concurrency limit.
+
+### limit(fn, ...args)
+
+Returns the promise returned by calling `fn(...args)`.
+
+#### fn
+
+Type: `Function`
+
+Promise-returning/async function.
+
+#### args
+
+Any arguments to pass through to `fn`.
+
+Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
+
+### limit.activeCount
+
+The number of promises that are currently running.
+
+### limit.pendingCount
+
+The number of promises that are waiting to run (i.e. their internal `fn` was not called yet).
+
+### limit.clearQueue()
+
+Discard pending promises that are waiting to run.
+
+This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
+
+Note: This does not cancel promises that are already running.
+
+## FAQ
+
+### How is this different from the [`p-queue`](https://github.com/sindresorhus/p-queue) package?
+
+This package is only about limiting the number of concurrent executions, while `p-queue` is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.

+# path-exists [![Build Status](https://travis-ci.org/sindresorhus/path-exists.svg?branch=master)](https://travis-ci.org/sindresorhus/path-exists)
+
+> Check if a path exists
+
+NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed.
+
+While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it.
+
+Never use this before handling a file though:
+
+> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
+
+
+## Install
+
+```
+$ npm install path-exists
+```
+
+
+## Usage
+
+```js
+// foo.js
+const pathExists = require('path-exists');
+
+(async () => {
+	console.log(await pathExists('foo.js'));
+	//=> true
+})();
+```
+
+
+## API
+
+### pathExists(path)
+
+Returns a `Promise<boolean>` of whether the path exists.
+
+### pathExists.sync(path)
+
+Returns a `boolean` of whether the path exists.

+Many of the types here should have been built-in. You can help by suggesting some of them to the [TypeScript project](https://github.com/Microsoft/TypeScript/blob/master/CONTRIBUTING.md).
+
+Either add this package as a dependency or copy-paste the needed types. No credit required. 👌
+
+PR welcome for additional commonly needed types and docs improvements. Read the [contributing guidelines](.github/contributing.md) first.

+## Usage
+
+```ts
+import {Except} from 'type-fest';
+
+type Foo = {
+	unicorn: string;
+	rainbow: boolean;
+};
+

+
+
+## API
+
+Click the type names for complete docs.
+
+### Basic
+
+- [`Primitive`](source/basic.d.ts) - Matches any [primitive value](https://developer.mozilla.org/en-US/docs/Glossary/Primitive).
+- [`Class`](source/basic.d.ts) - Matches a [`class` constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes).
+- [`TypedArray`](source/basic.d.ts) - Matches any [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray), like `Uint8Array` or `Float64Array`.
+- [`JsonObject`](source/basic.d.ts) - Matches a JSON object.
+- [`JsonArray`](source/basic.d.ts) - Matches a JSON array.
+- [`JsonValue`](source/basic.d.ts) - Matches any valid JSON value.
+- [`ObservableLike`](source/basic.d.ts) - Matches a value that is like an [Observable](https://github.com/tc39/proposal-observable).
+
+### Utilities
+
+- [`Except`](source/except.d.ts) - Create a type from an object type without certain keys. This is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type).
+- [`Mutable`](source/mutable.d.ts) - Convert an object with `readonly` keys into a mutable object. The inverse of `Readonly<T>`.
+- [`Merge`](source/merge.d.ts) - Merge two types into a new type. Keys of the second type overrides keys of the first type.
+- [`MergeExclusive`](source/merge-exclusive.d.ts) - Create a type that has mutually exclusive keys.
+- [`RequireAtLeastOne`](source/require-at-least-one.d.ts) - Create a type that requires at least one of the given keys.
+- [`RequireExactlyOne`](source/require-one.d.ts) - Create a type that requires exactly a single key of the given keys and disallows more.
+- [`PartialDeep`](source/partial-deep.d.ts) - Create a deeply optional version of another type. Use [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) if you only need one level deep.
+- [`ReadonlyDeep`](source/readonly-deep.d.ts) - Create a deeply immutable version of an `object`/`Map`/`Set`/`Array` type. Use [`Readonly<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1415-L1420) if you only need one level deep.
+- [`LiteralUnion`](source/literal-union.d.ts) - Create a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union. Workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729).
+- [`Promisable`](source/promisable.d.ts) - Create a type that represents either the value or the value wrapped in `PromiseLike`.
+- [`Opaque`](source/opaque.d.ts) - Create an [opaque type](https://codemix.com/opaque-types-in-javascript/).
+- [`SetOptional`](source/set-optional.d.ts) - Create a type that makes the given keys optional.
+- [`SetRequired`](source/set-required.d.ts) - Create a type that makes the given keys required.
+
+### Miscellaneous
+
+- [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file).
+
+
+## Declined types
+
+*If we decline a type addition, we will make sure to document the better solution here.*
+
+- [`Diff` and `Spread`](https://github.com/sindresorhus/type-fest/pull/7) - The PR author didn't provide any real-world use-cases and the PR went stale. If you think this type is useful, provide some real-world use-cases and we might reconsider.
+- [`Dictionary`](https://github.com/sindresorhus/type-fest/issues/33) - You only save a few characters (`Dictionary<number>` vs `Record<string, number>`) from [`Record`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1429-L1434), which is more flexible and well-known. Also, you shouldn't use an object as a dictionary. We have `Map` in JavaScript now.
+
+
+## Tips
+
+### Built-in types
+
+There are many advanced types most users don't know about.
+
+- [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) - Make all properties in `T` optional.

+
+## API
+
+Click the type names for complete docs.
+
+### Basic
+
+- [`Primitive`](source/basic.d.ts) - Matches any [primitive value](https://developer.mozilla.org/en-US/docs/Glossary/Primitive).
+- [`Class`](source/basic.d.ts) - Matches a [`class` constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes).
+- [`TypedArray`](source/basic.d.ts) - Matches any [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray), like `Uint8Array` or `Float64Array`.
+- [`JsonObject`](source/basic.d.ts) - Matches a JSON object.
+- [`JsonArray`](source/basic.d.ts) - Matches a JSON array.
+- [`JsonValue`](source/basic.d.ts) - Matches any valid JSON value.
+- [`ObservableLike`](source/basic.d.ts) - Matches a value that is like an [Observable](https://github.com/tc39/proposal-observable).
+
+### Utilities
+
+- [`Except`](source/except.d.ts) - Create a type from an object type without certain keys. This is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type).
+- [`Mutable`](source/mutable.d.ts) - Convert an object with `readonly` keys into a mutable object. The inverse of `Readonly<T>`.
+- [`Merge`](source/merge.d.ts) - Merge two types into a new type. Keys of the second type overrides keys of the first type.
+- [`MergeExclusive`](source/merge-exclusive.d.ts) - Create a type that has mutually exclusive keys.
+- [`RequireAtLeastOne`](source/require-at-least-one.d.ts) - Create a type that requires at least one of the given keys.
+- [`RequireExactlyOne`](source/require-exactly-one.d.ts) - Create a type that requires exactly a single key of the given keys and disallows more.
+- [`PartialDeep`](source/partial-deep.d.ts) - Create a deeply optional version of another type. Use [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) if you only need one level deep.
+- [`ReadonlyDeep`](source/readonly-deep.d.ts) - Create a deeply immutable version of an `object`/`Map`/`Set`/`Array` type. Use [`Readonly<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1415-L1420) if you only need one level deep.
+- [`LiteralUnion`](source/literal-union.d.ts) - Create a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union. Workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729).
+- [`Promisable`](source/promisable.d.ts) - Create a type that represents either the value or the value wrapped in `PromiseLike`.
+- [`Opaque`](source/opaque.d.ts) - Create an [opaque type](https://codemix.com/opaque-types-in-javascript/).
+- [`SetOptional`](source/set-optional.d.ts) - Create a type that makes the given keys optional.
+- [`SetRequired`](source/set-required.d.ts) - Create a type that makes the given keys required.
+- [`ValueOf`](source/value-of.d.ts) - Create a union of the given object's values, and optionally specify which keys to get the values from.
+- [`PromiseValue`](source/promise-value.d.ts) - Returns the type that is wrapped inside a `Promise`.
+- [`AsyncReturnType`](source/async-return-type.d.ts) - Unwrap the return type of a function that returns a `Promise`.
+- [`ConditionalKeys`](source/conditional-keys.d.ts) - Extract keys from a shape where values extend the given `Condition` type.
+- [`ConditionalPick`](source/conditional-pick.d.ts) - Like `Pick` except it selects properties from a shape where the values extend the given `Condition` type.
+- [`ConditionalExcept`](source/conditional-except.d.ts) - Like `Omit` except it removes properties from a shape where the values extend the given `Condition` type.
+- [`UnionToIntersection`](source/union-to-intersection.d.ts) - Convert a union type to an intersection type.
+- [`Stringified`](source/stringified.d.ts) - Create a type with the keys of the given type changed to `string` type.
+- [`FixedLengthArray`](source/fixed-length-array.d.ts) - Create a type that represents an array of the given type and length.
+- [`IterableElement`](source/iterable-element.d.ts) - Get the element type of an `Iterable`/`AsyncIterable`. For example, an array or a generator.
+- [`Entry`](source/entry.d.ts) - Create a type that represents the type of an entry of a collection.
+- [`Entries`](source/entries.d.ts) - Create a type that represents the type of the entries of a collection.
+- [`SetReturnType`](source/set-return-type.d.ts) - Create a function type with a return type of your choice and the same parameters as the given function type.
+- [`Asyncify`](source/asyncify.d.ts) - Create an async version of the given function type.
+
+### Miscellaneous
+
+- [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file).
+- [`TsConfigJson`](source/tsconfig-json.d.ts) - Type for [TypeScript's `tsconfig.json` file](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) (TypeScript 3.7).
+
+## Declined types
+
+*If we decline a type addition, we will make sure to document the better solution here.*
+
+- [`Diff` and `Spread`](https://github.com/sindresorhus/type-fest/pull/7) - The PR author didn't provide any real-world use-cases and the PR went stale. If you think this type is useful, provide some real-world use-cases and we might reconsider.
+- [`Dictionary`](https://github.com/sindresorhus/type-fest/issues/33) - You only save a few characters (`Dictionary<number>` vs `Record<string, number>`) from [`Record`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1429-L1434), which is more flexible and well-known. Also, you shouldn't use an object as a dictionary. We have `Map` in JavaScript now.
+- [`SubType`](https://github.com/sindresorhus/type-fest/issues/22) - The type is powerful, but lacks good use-cases and is prone to misuse.
+- [`ExtractProperties` and `ExtractMethods`](https://github.com/sindresorhus/type-fest/pull/4) - The types violate the single responsibility principle. Instead, refine your types into more granular type hierarchies.
+
+## Tips
+
+### Built-in types
+
+There are many advanced types most users don't know about.
+
+- [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) - Make all properties in `T` optional.

+
+## API
+
+### meow(helpText, options?)
+### meow(options)
+
+Returns an `object` with:
+
+- `input` *(Array)* - Non-flag arguments
+- `flags` *(Object)* - Flags converted to camelCase excluding aliases
+- `unnormalizedFlags` *(Object)* - Flags converted to camelCase including aliases
+- `pkg` *(Object)* - The `package.json` object
+- `help` *(string)* - The help text used with `--help`
+- `showHelp([exitCode=2])` *(Function)* - Show the help text and exit with `exitCode`
+- `showVersion()` *(Function)* - Show the version text and exit
+
+#### helpText
+
+Type: `string`
+
+Shortcut for the `help` option.
+
+#### options
+
+Type: `object`
+
+##### flags
+
+Type: `object`
+
+Define argument flags.
+
+The key is the flag name and the value is an object with any of:
+
+- `type`: Type of value. (Possible values: `string` `boolean` `number`)
+- `alias`: Usually used to define a short flag alias.
+- `default`: Default value when the flag is not specified.
+- `isRequired`: Determine if the flag is required. (Default: false)
+	- If it's only known at runtime whether the flag is required or not, you can pass a `Function` instead of a `boolean`, which based on the given flags and other non-flag arguments, should decide if the flag is required. Two arguments are passed to the function:
+	- The first argument is the **flags** object, which contains the flags converted to camel-case excluding aliases.
+	- The second argument is the **input** string array, which contains the non-flag arguments.
+	- The function should return a `boolean`, true if the flag is required, otherwise false.
+- `isMultiple`: Indicates a flag can be set multiple times. Values are turned into an array. (Default: false)
+	- Multiple values are provided by specifying the flag multiple times, for example, `$ foo -u rainbow -u cat`. Space- or comma-separated values are [currently *not* supported](https://github.com/sindresorhus/meow/issues/164).
+
+Example:
+
+```js
+flags: {
+	unicorn: {
+		type: 'string',
+		alias: 'u',
+		default: ['rainbow', 'cat'],
+		isMultiple: true,
+		isRequired: (flags, input) => {
+			if (flags.otherFlag) {
+				return true;
+			}
+
+			return false;
+		}
+	}
+}
+```
+
+##### description
+
+Type: `string | boolean`\
+Default: The package.json `"description"` property
+
+Description to show above the help text.
+
+Set it to `false` to disable it altogether.
+
+##### help
+
+Type: `string | boolean`
+
+The help text you want shown.
+
+The input is reindented and starting/ending newlines are trimmed which means you can use a [template literal](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/template_strings) without having to care about using the correct amount of indent.
+
+The description will be shown above your help text automatically.
+
+##### version
+
+Type: `string | boolean`\
+Default: The package.json `"version"` property
+
+Set a custom version output.
+
+##### autoHelp
+
+Type: `boolean`\
+Default: `true`
+
+Automatically show the help text when the `--help` flag is present. Useful to set this value to `false` when a CLI manages child CLIs with their own help text.
+
+This option is only considered when there is only one argument in `process.argv`.
+
+##### autoVersion
+
+Type: `boolean`\
+Default: `true`
+
+Automatically show the version text when the `--version` flag is present. Useful to set this value to `false` when a CLI manages child CLIs with their own version text.
+
+ This option is only considered when there is only one argument in `process.argv`.
+
+##### pkg
+
+Type: `object`\
+Default: Closest package.json upwards
+
+package.json as an `object`.
+
+*You most likely don't need this option.*
+
+##### argv
+
+Type: `string[]`\
+Default: `process.argv.slice(2)`
+
+Custom arguments object.
+
+##### inferType
+
+Type: `boolean`\
+Default: `false`
+
+Infer the argument type.
+
+By default, the argument `5` in `$ foo 5` becomes a string. Enabling this would infer it as a number.
+
+##### booleanDefault
+
+Type: `boolean | null | undefined`\
+Default: `false`
+
+Value of `boolean` flags not defined in `argv`.
+
+If set to `undefined`, the flags not defined in `argv` will be excluded from the result.
+The `default` value set in `boolean` flags take precedence over `booleanDefault`.
+
+_Note: If used in conjunction with `isMultiple`, the default flag value is set to `[]`._
+
+__Caution: Explicitly specifying `undefined` for `booleanDefault` has different meaning from omitting key itself.__
+
+Example:
+
+```js
+const meow = require('meow');
+
+const cli = meow(`
+	Usage
+	  $ foo
+
+	Options
+	  --rainbow, -r  Include a rainbow
+	  --unicorn, -u  Include a unicorn
+	  --no-sparkles  Exclude sparkles
+
+	Examples
+	  $ foo
+	  🌈 unicorns✨🌈
+`, {
+	booleanDefault: undefined,
+	flags: {
+		rainbow: {
+			type: 'boolean',
+			default: true,
+			alias: 'r'
+		},
+		unicorn: {
+			type: 'boolean',
+			default: false,
+			alias: 'u'
+		},
+		cake: {
+			type: 'boolean',
+			alias: 'c'
+		},
+		sparkles: {
+			type: 'boolean',
+			default: true
+		}
+	}
+});
+/*
+{
+	flags: {
+		rainbow: true,
+		unicorn: false,
+		sparkles: true
+	},
+	unnormalizedFlags: {
+		rainbow: true,
+		r: true,
+		unicorn: false,
+		u: false,
+		sparkles: true
+	},
+	…
+}
+*/
+```
+
+##### hardRejection
+
+Type: `boolean`\
+Default: `true`
+
+Whether to use [`hard-rejection`](https://github.com/sindresorhus/hard-rejection) or not. Disabling this can be useful if you need to handle `process.on('unhandledRejection')` yourself.
+
+#### allowUnknownFlags
+
+Type `boolean`\
+Default: `true`
+
+Whether to allow unknown flags or not.
+
+## Promises
+
+Meow will make unhandled rejected promises [fail hard](https://github.com/sindresorhus/hard-rejection) instead of the default silent fail. Meaning you don't have to manually `.catch()` promises used in your CLI.
+
+## Tips
+
+See [`chalk`](https://github.com/chalk/chalk) if you want to colorize the terminal output.
+
+See [`get-stdin`](https://github.com/sindresorhus/get-stdin) if you want to accept input from stdin.
+
+See [`conf`](https://github.com/sindresorhus/conf) if you need to persist some data.
+
+See [`update-notifier`](https://github.com/yeoman/update-notifier) if you want update notifications.
