+
+
+### Features
+
+* automatically use the `fibers` package if it is possible ([#744](https://github.com/webpack-contrib/sass-loader/issues/744)) ([96184e1](https://github.com/webpack-contrib/sass-loader/commit/96184e1))
+* source map generation depends on the `devtool` option ([#743](https://github.com/webpack-contrib/sass-loader/issues/743)) ([fcea88e](https://github.com/webpack-contrib/sass-loader/commit/fcea88e))

+
+

+# [7.0.0](https://github.com/webpack-contrib/sass-loader/compare/v6.0.7...v7.0.0) (2018-04-13)
+
+
+### Features
+
+* Refactor resolving and simplify webpack config aliases (#479) ([e0fde1a](https://github.com/webpack-contrib/sass-loader/commit/e0fde1a))
+* Remove `node-sass` from `peerDependencies` (#533) ([6439cef](https://github.com/webpack-contrib/sass-loader/commit/6439cef))

+
+* Drop official node 4 support
+* This slightly changes the resolving algorithm. Should not break in normal usage, but might break in complex configurations.
+* The sass-loader throws an error at runtime now and refuses to compile if the peer dependency is wrong. This could break applications where npm's peer dependency warning was just ignored.

+# sass-loader
+
+Loads a Sass/SCSS file and compiles it to CSS.
+
+## Getting Started
+
+To begin, you'll need to install `sass-loader`:
+
+```console
+npm install sass-loader sass webpack --save-dev
+```
+
+`sass-loader` requires you to install either [Dart Sass](https://github.com/sass/dart-sass) or [Node Sass](https://github.com/sass/node-sass) on your own (more documentation can be found below).
+
+This allows you to control the versions of all your dependencies, and to choose which Sass implementation to use.
+
+> ℹ️ We recommend using [Dart Sass](https://github.com/sass/dart-sass).
+
+> ⚠ [Node Sass](https://github.com/sass/node-sass) does not work with [Yarn PnP](https://classic.yarnpkg.com/en/docs/pnp/) feature.
+
+Chain the `sass-loader` with the [css-loader](https://github.com/webpack-contrib/css-loader) and the [style-loader](https://github.com/webpack-contrib/style-loader) to immediately apply all styles to the DOM or the [mini-css-extract-plugin](https://github.com/webpack-contrib/mini-css-extract-plugin) to extract it into a separate file.
+
+Then add the loader to your Webpack configuration. For example:
+
+**app.js**
+
+```js
+import "./style.scss";
+```
+
+**style.scss**
+
+```scss
+$body-color: red;
+
+body {
+  color: $body-color;
+}
+```
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          // Creates `style` nodes from JS strings
+          "style-loader",
+          // Translates CSS into CommonJS
+          "css-loader",
+          // Compiles Sass to CSS
+          "sass-loader",
+        ],
+      },
+    ],
+  },
+};
+```
+
+Finally run `webpack` via your preferred method.
+
+### Resolving `import` at-rules
+
+Webpack provides an [advanced mechanism to resolve files](https://webpack.js.org/concepts/module-resolution/).
+
+The `sass-loader` uses Sass's custom importer feature to pass all queries to the Webpack resolving engine. Thus you can import your Sass modules from `node_modules`. Just prepend them with a `~` to tell Webpack that this is not a relative import:
+
+```scss
+@import "~bootstrap";
+```
+
+It's important to only prepend it with `~`, because `~/` resolves to the home directory.
+Webpack needs to distinguish between `bootstrap` and `~bootstrap` because CSS and Sass files have no special syntax for importing relative files.
+Writing `@import "style.scss"` is the same as `@import "./style.scss";`
+
+### Problems with `url(...)`
+
+Since Sass implementations don't provide [url rewriting](https://github.com/sass/libsass/issues/532), all linked assets must be relative to the output.
+
+- If you pass the generated CSS on to the `css-loader`, all urls must be relative to the entry-file (e.g. `main.scss`).
+- If you're just generating CSS without passing it to the `css-loader`, it must be relative to your web root.
+
+You will be disrupted by this first issue. It is natural to expect relative references to be resolved against the `.sass`/`.scss` file in which they are specified (like in regular `.css` files).
+
+Thankfully there are a two solutions to this problem:
+
+- Add the missing url rewriting using the [resolve-url-loader](https://github.com/bholloway/resolve-url-loader). Place it before `sass-loader` in the loader chain.
+- Library authors usually provide a variable to modify the asset path. [bootstrap-sass](https://github.com/twbs/bootstrap-sass) for example has an `$icon-font-path`.

+|     **[`sassOptions`](#sassoptions)**     | `{Object\|Function}` | defaults values for Sass implementation | Options for Sass.                                                 |
+|       **[`sourceMap`](#sourcemap)**       |     `{Boolean}`      |           `compiler.devtool`            | Enables/Disables generation of source maps.                       |
+|  **[`additionalData`](#additionaldata)**  | `{String\|Function}` |               `undefined`               | Prepends/Appends `Sass`/`SCSS` code before the actual entry file. |
+| **[`webpackImporter`](#webpackimporter)** |     `{Boolean}`      |                 `true`                  | Enables/Disables the default Webpack importer.                    |
+
+### `implementation`
+
+Type: `Object`
+Default: `sass`
+
+The special `implementation` option determines which implementation of Sass to use.
+
+By default the loader resolve the implementation based on your dependencies.
+Just add required implementation to `package.json` (`sass` or `node-sass` package) and install dependencies.
+
+Example where the `sass-loader` loader uses the `sass` (`dart-sass`) implementation:
+
+**package.json**
+
+```json
+{
+  "devDependencies": {
+    "sass-loader": "^7.2.0",
+    "sass": "^1.22.10"
+  }
+}
+```
+
+Example where the `sass-loader` loader uses the `node-sass` implementation:
+
+**package.json**
+
+```json
+{
+  "devDependencies": {
+    "sass-loader": "^7.2.0",
+    "node-sass": "^5.0.0"
+  }
+}
+```
+
+Beware the situation when `node-sass` and `sass` were installed! By default the `sass-loader` prefers `sass`.
+In order to avoid this situation you can use the `implementation` option.
+
+The `implementation` options either accepts `sass` (`Dart Sass`) or `node-sass` as a module.
+
+For example, to use Dart Sass, you'd pass:
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              // Prefer `dart-sass`
+              implementation: require("sass"),
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+Note that when using `sass` (`Dart Sass`), **synchronous compilation is twice as fast as asynchronous compilation** by default, due to the overhead of asynchronous callbacks.
+To avoid this overhead, you can use the [fibers](https://www.npmjs.com/package/fibers) package to call asynchronous importers from the synchronous code path.
+
+We automatically inject the [`fibers`](https://github.com/laverdet/node-fibers) package (setup `sassOptions.fiber`) if is possible (i.e. you need install the [`fibers`](https://github.com/laverdet/node-fibers) package).
+
+**package.json**
+
+```json
+{
+  "devDependencies": {
+    "sass-loader": "^7.2.0",
+    "sass": "^1.22.10",
+    "fibers": "^4.0.1"
+  }
+}
+```
+
+You can disable automatically injecting the [`fibers`](https://github.com/laverdet/node-fibers) package by passing a `false` value for the `sassOptions.fiber` option.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              implementation: require("sass"),
+              sassOptions: {
+                fiber: false,
+              },
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+You can also pass the `fiber` value using this code:
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              implementation: require("sass"),
+              sassOptions: {
+                fiber: require("fibers"),
+              },
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+### `sassOptions`
+
+Type: `Object|Function`
+Default: defaults values for Sass implementation
+
+Options for [Dart Sass](http://sass-lang.com/dart-sass) or [Node Sass](https://github.com/sass/node-sass) implementation.
+
+> ℹ️ The `indentedSyntax` option has `true` value for the `sass` extension.
+
+> ℹ️ Options such as `data` and `file` are unavailable and will be ignored.
+
+> ℹ We recommend not to set the `outFile`, `sourceMapContents`, `sourceMapEmbed`, `sourceMapRoot` options because `sass-loader` automatically sets these options when the `sourceMap` option is `true`.
+
+> ℹ️ Access to the [loader context](https://webpack.js.org/api/loaders/#the-loader-context) inside the custom importer can be done using the `this.webpackLoaderContext` property.
+
+There is a slight difference between the `sass` (`dart-sass`) and `node-sass` options.
+
+Please consult documentation before using them:
+
+- [Dart Sass documentation](https://github.com/sass/dart-sass#javascript-api) for all available `sass` options.
+- [Node Sass documentation](https://github.com/sass/node-sass/#options) for all available `node-sass` options.
+
+#### `Object`
+
+Use and object for the Sass implementation setup.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              sassOptions: {
+                indentWidth: 4,
+                includePaths: ["absolute/path/a", "absolute/path/b"],
+              },
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+#### `Function`
+
+Allows to setup the Sass implementation by setting different options based on the loader context.
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              sassOptions: (loaderContext) => {
+                // More information about available properties https://webpack.js.org/api/loaders/
+                const { resourcePath, rootContext } = loaderContext;
+                const relativePath = path.relative(rootContext, resourcePath);
+
+                if (relativePath === "styles/foo.scss") {
+                  return {
+                    includePaths: ["absolute/path/c", "absolute/path/d"],
+                  };
+                }
+
+                return {
+                  includePaths: ["absolute/path/a", "absolute/path/b"],
+                };
+              },
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+### `sourceMap`
+
+Type: `Boolean`
+Default: depends on the `compiler.devtool` value
+
+Enables/Disables generation of source maps.
+
+By default generation of source maps depends on the [`devtool`](https://webpack.js.org/configuration/devtool/) option.
+All values enable source map generation except `eval` and `false` value.
+
+> ℹ If a `true` the `sourceMap`, `sourceMapRoot`, `sourceMapEmbed`, `sourceMapContents` and `omitSourceMapUrl` from `sassOptions` will be ignored.
+
+**webpack.config.js**
+
+```js
+module.exports = {

+
+### `additionalData`
+
+Type: `String|Function`
+Default: `undefined`
+
+Prepends `Sass`/`SCSS` code before the actual entry file.
+In this case, the `sass-loader` will not override the `data` option but just **prepend** the entry's content.
+
+This is especially useful when some of your Sass variables depend on the environment:
+
+#### `String`

+    ],
+  },
+};
+```
+
+### `webpackImporter`
+
+Type: `Boolean`
+Default: `true`
+
+Enables/Disables the default Webpack importer.
+
+This can improve performance in some cases. Use it with caution because aliases and `@import` at-rules starting with `~` will not work.
+You can pass own `importer` to solve this (see [`importer docs`](https://github.com/sass/node-sass#importer--v200---experimental)).
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          "css-loader",
+          {
+            loader: "sass-loader",
+            options: {
+              webpackImporter: false,
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+## Examples
+
+### Extracts CSS into separate files
+
+For production builds it's recommended to extract the CSS from your bundle being able to use parallel loading of CSS/JS resources later on.
+
+There are two possibilities to extract a style sheet from the bundle:
+
+- [mini-css-extract-plugin](https://github.com/webpack-contrib/mini-css-extract-plugin) (use this, when using webpack 4 configuration. Works in all use-cases)
+- [extract-loader](https://github.com/peerigon/extract-loader) (simpler, but specialized on the css-loader's output)
+
+**webpack.config.js**
+
+```js
+const MiniCssExtractPlugin = require("mini-css-extract-plugin");
+
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          // fallback to style-loader in development
+          process.env.NODE_ENV !== "production"
+            ? "style-loader"
+            : MiniCssExtractPlugin.loader,
+          "css-loader",
+          "sass-loader",
+        ],
+      },
+    ],
+  },
+  plugins: [
+    new MiniCssExtractPlugin({
+      // Options similar to the same options in webpackOptions.output
+      // both options are optional
+      filename: "[name].css",
+      chunkFilename: "[id].css",
+    }),
+  ],
+};
+```
+
+### Source maps
+
+Enables/Disables generation of source maps.
+
+To enable CSS source maps, you'll need to pass the `sourceMap` option to the `sass-loader` _and_ the css-loader.
+
+**webpack.config.js**
+
+```javascript
+module.exports = {
+  devtool: "source-map", // any "source-map"-like devtool is possible
+  module: {
+    rules: [
+      {
+        test: /\.s[ac]ss$/i,
+        use: [
+          "style-loader",
+          {
+            loader: "css-loader",
+            options: {
+              sourceMap: true,
+            },
+          },
+          {
+            loader: "sass-loader",
+            options: {
+              sourceMap: true,
+            },
+          },
+        ],
+      },
+    ],
+  },
+};
+```
+
+If you want to edit the original Sass files inside Chrome, [there's a good blog post](https://medium.com/@toolmantim/getting-started-with-css-sourcemaps-and-in-browser-sass-editing-b4daab987fb0). Checkout [test/sourceMap](https://github.com/webpack-contrib/sass-loader/tree/master/test) for a running example.

+# schema-utils
+
+Package for validate options in loaders and plugins.
+
+## Getting Started
+
+To begin, you'll need to install `schema-utils`:
+
+```console
+npm install schema-utils
+```
+
+## API
+
+**schema.json**
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "option": {
+      "type": "boolean"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { option: true };
+const configuration = { name: "Loader Name/Plugin Name/Name" };
+
+validate(schema, options, configuration);
+```
+
+### `schema`
+
+Type: `String`
+
+JSON schema.
+
+Simple example of schema:
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "name": {
+      "description": "This is description of option.",
+      "type": "string"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+### `options`
+
+Type: `Object`
+
+Object with options.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, { name: 123 }, { name: "MyPlugin" });
+```
+
+### `configuration`
+
+Allow to configure validator.
+
+There is an alternative method to configure the `name` and`baseDataPath` options via the `title` property in the schema.
+For example:
+
+```json
+{
+  "title": "My Loader options",
+  "type": "object",
+  "properties": {
+    "name": {
+      "description": "This is description of option.",
+      "type": "string"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+The last word used for the `baseDataPath` option, other words used for the `name` option.
+Based on the example above the `name` option equals `My Loader`, the `baseDataPath` option equals `options`.
+
+#### `name`
+
+Type: `Object`
+Default: `"Object"`
+
+Allow to setup name in validation errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, { name: "MyPlugin" });
+```
+
+```shell
+Invalid configuration object. MyPlugin has been initialised using a configuration object that does not match the API schema.
+ - configuration.optionName should be a integer.
+```
+
+#### `baseDataPath`
+
+Type: `String`
+Default: `"configuration"`
+
+Allow to setup base data path in validation errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, { name: "MyPlugin", baseDataPath: "options" });
+```
+
+```shell
+Invalid options object. MyPlugin has been initialised using an options object that does not match the API schema.
+ - options.optionName should be a integer.
+```
+
+#### `postFormatter`
+
+Type: `Function`
+Default: `undefined`
+
+Allow to reformat errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, {
+  name: "MyPlugin",
+  postFormatter: (formattedError, error) => {
+    if (error.keyword === "type") {
+      return `${formattedError}\nAdditional Information.`;
+    }
+
+    return formattedError;
+  },
+});
+```
+
+```shell
+Invalid options object. MyPlugin has been initialized using an options object that does not match the API schema.
+ - options.optionName should be a integer.
+   Additional Information.
+```
+
+## Examples
+
+**schema.json**
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "name": {
+      "type": "string"
+    },
+    "test": {
+      "anyOf": [
+        { "type": "array" },
+        { "type": "string" },
+        { "instanceof": "RegExp" }
+      ]
+    },
+    "transform": {
+      "instanceof": "Function"
+    },
+    "sourceMap": {
+      "type": "boolean"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+### `Loader`
+
+```js
+import { getOptions } from "loader-utils";
+import { validate } from "schema-utils";
+
+import schema from "path/to/schema.json";
+
+function loader(src, map) {
+  const options = getOptions(this);
+
+  validate(schema, options, {
+    name: "Loader Name",
+    baseDataPath: "options",
+  });
+
+  // Code...
+}
+
+export default loader;
+```
+
+### `Plugin`
+
+```js
+import { validate } from "schema-utils";
+
+import schema from "path/to/schema.json";
+
+class Plugin {
+  constructor(options) {
+    validate(schema, options, {
+      name: "Plugin Name",
+      baseDataPath: "options",
+    });
+
+    this.options = options;
+  }
+
+  apply(compiler) {
+    // Code...
+  }
+}
+
+export default Plugin;
+```

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'

+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, prerelease, or release.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-n <0|1|false>
+        Base number for prerelease identifier (default: 0).
+        Use false to omit the number altogether.
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+Support for stripping a leading "v" is kept for compatibility with `v1.0.0` of the SemVer
+specification but should not be used anymore.
+
+## Ranges
+
+A `version range` is a set of `comparators` that specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and
+would match the versions `2.0.0` and `3.1.0`, but not the versions
+`1.0.1` or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.
+Version `3.4.5` *would* satisfy the range because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose of this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range-matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for range-matching)
+by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+To get out of the prerelease phase, use the `release` option:
+
+```bash
+$ semver 1.2.4-beta.1 -i release
+1.2.4
+```
+
+#### Prerelease Identifier Base
+
+The method `.inc` takes an optional parameter 'identifierBase' string
+that will let you let your prerelease number as zero-based or one-based.
+Set to `false` to omit the prerelease number altogether.
+If you do not specify this parameter, it will default to zero-based.
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', '1')
+// '1.2.4-beta.1'
+```
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', false)
+// '1.2.4-beta'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n 1
+1.2.4-beta.1
+```
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n false
+1.2.4-beta
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless
+  `includePrerelease` is specified, in which case any version at all
+  satisfies)
+* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0-0`
+* `^0.2.3` := `>=0.2.3 <0.3.0-0`
+* `^0.0.3` := `>=0.0.3 <0.0.4-0`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0-0`
+* `^0.0.x` := `>=0.0.0 <0.1.0-0`
+* `^0.0` := `>=0.0.0 <0.1.0-0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0-0`
+* `^0.x` := `>=0.0.0 <1.0.0-0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *

+
+Note: Prerelease identifiers (`pre`) use `nr` for numeric parts, which
+disallows leading zeros (e.g., `1.2.3-00` is invalid). Build metadata
+identifiers (`build`) allow any alphanumeric string including leading
+zeros (e.g., `1.2.3+00` is valid). This matches the
+[SemVer 2.0.0 specification](https://semver.org/#spec-item-9).
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`: Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`: Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, releaseType, options, identifier, identifierBase)`: 
+  Return the version incremented by the release
+  type (`major`, `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, `prerelease`, or `release`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, `prerelease` will work the
+    same as `prepatch`. It increments the patch version and then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+  * `release` will remove any prerelease part of the version.
+  * `identifier` can be used to prefix `premajor`, `preminor`,
+    `prepatch`, or `prerelease` version increments. `identifierBase`
+    is the base to be used for the `prerelease` identifier.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+* `truncate(v, releaseType)`: Return the version with components _lower_
+  than `releaseType` dropped off, e.g.:
+  * `major` removes build & prerelease info and sets minor & patch to 0.
+  * `minor` removes build & prerelease info, and sets patch to 0
+  * `patch` removes build & prerelease info
+  * All prerelease types remove build info only
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of `compare`.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`.
+* `diff(v1, v2)`: Returns the difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Sorting
+
+* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` 
+  function.
+* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on
+  the `compareBuild` function in descending order.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid.
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can match
+  the given range.
+* `gtr(version, range)`: Return `true` if the version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if the version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the range comparators intersect.
+* `simplifyRange(versions, range)`: Return a "simplified" range that
+  matches the same items in the `versions` list as the range specified.  Note
+  that it does *not* guarantee that it would match the same versions in all
+  cases, only for the set of versions provided.  This is useful when
+  generating ranges by joining together multiple versions with `||`
+  programmatically, to provide the user with something a bit more
+  ergonomic.  If the provided range is shorter in string-length than the
+  generated range, then that is returned.
+* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
+  entirely contained by the `superRange` range.
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+If the `options.includePrerelease` flag is set, then the `coerce` result will contain
+prerelease and build parts of a version.  For example, `1.2.3.4-rc.1+rev.2`
+will preserve prerelease `rc.1` and build `rev.2` in the result.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided
+version is not valid a null will be returned. This does not work for
+ranges.
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `'2.1.5'`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`
+
+## Constants
+
+As a convenience, helper constants are exported to provide information about what `node-semver` supports:
+
+### `RELEASE_TYPES`
+
+- major
+- premajor
+- minor
+- preminor
+- patch
+- prepatch
+- prerelease
+
+```
+const semver = require('semver');
+
+if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
+  console.log('This is a valid release type!');
+} else {
+  console.warn('This is NOT a valid release type!');
+}
+```
+
+### `SEMVER_SPEC_VERSION`
+
+2.0.0
+
+```
+const semver = require('semver');
+
+console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
+```
+

+eg), and then pull the module name into the documentation for that specific
+thing.
