+# globals
+
+> Global identifiers from different JavaScript environments
+
+It's just a [JSON file](globals.json), so use it in any environment.
+
+This package is used by ESLint.
+
+**This package [no longer accepts](https://github.com/sindresorhus/globals/issues/82) new environments. If you need it for ESLint, just [create a plugin](http://eslint.org/docs/developer-guide/working-with-plugins#environments-in-plugins).**
+
+## Install
+
+```
+$ npm install globals
+```
+
+## Usage
+
+```js
+const globals = require('globals');
+
+console.log(globals.browser);
+/*
+{
+	addEventListener: false,
+	applicationCache: false,
+	ArrayBuffer: false,
+	atob: false,
+	…
+}
+*/
+```
+
+Each global is given a value of `true` or `false`. A value of `true` indicates that the variable may be overwritten. A value of `false` indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be `false` unless we hear otherwise.
+
+For Node.js this package provides two sets of globals:
+
+- `globals.nodeBuiltin`: Globals available to all code running in Node.js.
+	These will usually be available as properties on the `global` object and include `process`, `Buffer`, but not CommonJS arguments like `require`.
+	See: https://nodejs.org/api/globals.html
+- `globals.node`: A combination of the globals from `nodeBuiltin` plus all CommonJS arguments ("CommonJS module scope").
+	See: https://nodejs.org/api/modules.html#modules_the_module_scope
+
+When analyzing code that is known to run outside of a CommonJS wrapper, for example, JavaScript modules, `nodeBuiltin` can find accidental CommonJS references.

+# ignore
+
+`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore [spec](http://git-scm.com/docs/gitignore).
+
+Pay attention that [`minimatch`](https://www.npmjs.org/package/minimatch) does not work in the gitignore way. To filter filenames according to .gitignore file, I recommend this module.
+
+##### Tested on
+
+- Linux + Node: `0.8` - `7.x`
+- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
+
+Actually, `ignore` does not rely on any versions of node specially.
+
+Since `4.0.0`, ignore will no longer support `node < 6` by default, to use in node < 6, `require('ignore/legacy')`. For details, see [CHANGELOG](https://github.com/kaelzhang/node-ignore/blob/master/CHANGELOG.md).

+- [`Pathname` Conventions](#pathname-conventions)
+- [Guide for 2.x -> 3.x](#upgrade-2x---3x)
+- [Guide for 3.x -> 4.x](#upgrade-3x---4x)
+- See Also:
+  - [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
+
+## Usage
+
+```js
+import ignore from 'ignore'
+const ig = ignore().add(['.abc/*', '!.abc/d/'])
+```
+
+### Filter the given paths
+
+```js
+const paths = [
+  '.abc/a.js',    // filtered out
+  '.abc/d/e.js'   // included
+]
+
+ig.filter(paths)        // ['.abc/d/e.js']
+ig.ignores('.abc/a.js') // true
+```
+
+### As the filter function
+
+```js
+paths.filter(ig.createFilter()); // ['.abc/d/e.js']
+```
+
+### Win32 paths will be handled
+
+```js
+ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
+// if the code above runs on windows, the result will be
+// ['.abc\\d\\e.js']
+```
+
+## Why another ignore?
+
+- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
+
+- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
+  - `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
+  - `ignore` don't cares about sub-modules of git projects.
+
+- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
+  - '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
+  - '`**/foo`' should match '`foo`' anywhere.
+  - Prevent re-including a file if a parent directory of that file is excluded.
+  - Handle trailing whitespaces:
+    - `'a '`(one space) should not match `'a  '`(two spaces).
+    - `'a \ '` matches `'a  '`
+  - All test cases are verified with the result of `git check-ignore`.
+
+# Methods
+
+## .add(pattern: string | Ignore): this
+## .add(patterns: Array<string | Ignore>): this
+
+- **pattern** `String | Ignore` An ignore pattern string, or the `Ignore` instance
+- **patterns** `Array<String | Ignore>` Array of ignore patterns.
+
+Adds a rule or several rules to the current manager.
+
+Returns `this`
+
+Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
+
+```js
+ignore().add('#abc').ignores('#abc')    // false
+ignore().add('\#abc').ignores('#abc')   // true
+```
+
+`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
+
+```js
+ignore()
+.add(fs.readFileSync(filenameOfGitignore).toString())
+.filter(filenames)
+```
+
+`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
+
+## <strike>.addIgnoreFile(path)</strike>
+
+REMOVED in `3.x` for now.
+
+To upgrade `ignore@2.x` up to `3.x`, use
+
+```js
+import fs from 'fs'
+
+if (fs.existsSync(filename)) {
+  ignore().add(fs.readFileSync(filename).toString())
+}
+```
+
+instead.
+
+## .filter(paths: Array<Pathname>): Array<Pathname>
+
+```ts
+type Pathname = string
+```
+
+Filters the given array of pathnames, and returns the filtered array.
+
+- **paths** `Array.<Pathname>` The array of `pathname`s to be filtered.
+
+### `Pathname` Conventions:
+
+#### 1. `Pathname` should be a `path.relative()`d pathname
+
+`Pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory.
+
+```js
+// WRONG
+ig.ignores('./abc')
+
+// WRONG, for it will never happen.
+// If the gitignore rule locates at the root directory,
+// `'/abc'` should be changed to `'abc'`.
+// ```
+// path.relative('/', '/abc')  -> 'abc'
+// ```
+ig.ignores('/abc')
+
+// Right
+ig.ignores('abc')
+
+// Right
+ig.ignores(path.join('./abc'))  // path.join('./abc') -> 'abc'
+```
+
+In other words, each `Pathname` here should be a relative path to the directory of the gitignore rules.
+
+Suppose the dir structure is:
+
+```
+/path/to/your/repo
+    |-- a
+    |   |-- a.js
+    |
+    |-- .b
+    |
+    |-- .c
+         |-- .DS_store
+```
+
+Then the `paths` might be like this:
+
+```js
+[
+  'a/a.js'
+  '.b',
+  '.c/.DS_store'
+]
+```
+
+Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
+
+```js
+import glob from 'glob'
+
+glob('**', {
+  // Adds a / character to directory matches.
+  mark: true
+}, (err, files) => {
+  if (err) {
+    return console.error(err)
+  }
+
+  let filtered = ignore().add(patterns).filter(files)
+  console.log(filtered)
+})
+```
+
+#### 2. filenames and dirnames
+
+`node-ignore` does NO `fs.stat` during path matching, so for the example below:
+
+```js
+ig.add('config/')
+
+// `ig` does NOT know if 'config' is a normal file, directory or something
+ig.ignores('config')    // And it returns `false`
+
+ig.ignores('config/')   // returns `true`
+```
+
+Specially for people who develop some library based on `node-ignore`, it is important to understand that.
+
+## .ignores(pathname: Pathname): boolean
+
+> new in 3.2.0
+
+Returns `Boolean` whether `pathname` should be ignored.
+
+```js
+ig.ignores('.abc/a.js')    // true
+```
+
+## .createFilter()
+
+Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
+
+Returns `function(path)` the filter function.
+
+## `options.ignorecase` since 4.0.0
+
+Similar as the `core.ignorecase` option of [git-config](https://git-scm.com/docs/git-config), `node-ignore` will be case insensitive if `options.ignorecase` is set to `true` (default value), otherwise case sensitive.
+
+```js
+const ig = ignore({
+  ignorecase: false
+})
+
+ig.add('*.png')
+
+ig.ignores('*.PNG')  // false
+```
+
+****
+
+# Upgrade Guide
+
+## Upgrade 2.x -> 3.x
+
+- All `options` of 2.x are unnecessary and removed, so just remove them.
+- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
+- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
+
+## Upgrade 3.x -> 4.x
+
+Since `4.0.0`, `ignore` will no longer support node < 6, to use `ignore` in node < 6:
+
+```js
+var ignore = require('ignore/legacy')
+```

+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.
+
+## Install
+

+
+## 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.
+
+### Template literal types
+
+*Note:* These require [TypeScript 4.1 or newer](https://devblogs.microsoft.com/typescript/announcing-typescript-4-1/#template-literal-types).
+
+- [`CamelCase`](ts41/camel-case.d.ts) – Convert a string literal to camel-case (`fooBar`).
+- [`KebabCase`](ts41/kebab-case.d.ts) – Convert a string literal to kebab-case (`foo-bar`).
+- [`PascalCase`](ts41/pascal-case.d.ts) – Converts a string literal to pascal-case (`FooBar`)
+- [`SnakeCase`](ts41/snake-case.d.ts) – Convert a string literal to snake-case (`foo_bar`).
+- [`DelimiterCase`](ts41/delimiter-case.d.ts) – Convert a string literal to a custom string delimiter casing.
+
+### 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.
