+
+## Methods
+
+### `getOptions`
+
+Recommended way to retrieve the options of a loader invocation:
+
+```javascript
+// inside your loader
+const options = loaderUtils.getOptions(this);
+```
+
+1. If `this.query` is a string:
+	- Tries to parse the query string and returns a new object
+	- Throws if it's not a valid query string
+2. If `this.query` is object-like, it just returns `this.query`
+3. In any other case, it just returns `null`
+
+**Please note:** The returned `options` object is *read-only*. It may be re-used across multiple invocations.
+If you pass it on to another library, make sure to make a *deep copy* of it:
+
+```javascript
+const options = Object.assign(
+	{},
+	defaultOptions,
+	loaderUtils.getOptions(this) // it is safe to pass null to Object.assign()
+);
+// don't forget nested objects or arrays
+options.obj = Object.assign({}, options.obj); 
+options.arr = options.arr.slice();
+someLibrary(options);
+```
+
+[clone](https://www.npmjs.com/package/clone) is a good library to make a deep copy of the options.
+
+#### Options as query strings
+
+If the loader options have been passed as loader query string (`loader?some&params`), the string is parsed by using [`parseQuery`](#parsequery).
+
+### `parseQuery`
+
+Parses a passed string (e.g. `loaderContext.resourceQuery`) as a query string, and returns an object.
+
+``` javascript
+const params = loaderUtils.parseQuery(this.resourceQuery); // resource: `file?param1=foo`
+if (params.param1 === "foo") {
+	// do something
+}
+```
+
+The string is parsed like this:
+
+``` text
+                             -> Error
+?                            -> {}
+?flag                        -> { flag: true }
+?+flag                       -> { flag: true }
+?-flag                       -> { flag: false }
+?xyz=test                    -> { xyz: "test" }
+?xyz=1                       -> { xyz: "1" } // numbers are NOT parsed
+?xyz[]=a                     -> { xyz: ["a"] }
+?flag1&flag2                 -> { flag1: true, flag2: true }
+?+flag1,-flag2               -> { flag1: true, flag2: false }
+?xyz[]=a,xyz[]=b             -> { xyz: ["a", "b"] }
+?a%2C%26b=c%2C%26d           -> { "a,&b": "c,&d" }
+?{data:{a:1},isJSON5:true}   -> { data: { a: 1 }, isJSON5: true }
+```
+
+### `stringifyRequest`
+
+Turns a request into a string that can be used inside `require()` or `import` while avoiding absolute paths.
+Use it instead of `JSON.stringify(...)` if you're generating code inside a loader.
+
+**Why is this necessary?** Since webpack calculates the hash before module paths are translated into module ids, we must avoid absolute paths to ensure
+consistent hashes across different compilations.
+
+This function:
+
+- resolves absolute requests into relative requests if the request and the module are on the same hard drive
+- replaces `\` with `/` if the request and the module are on the same hard drive
+- won't change the path at all if the request and the module are on different hard drives
+- applies `JSON.stringify` to the result
+
+```javascript
+loaderUtils.stringifyRequest(this, "./test.js");
+// "\"./test.js\""
+
+loaderUtils.stringifyRequest(this, ".\\test.js");
+// "\"./test.js\""
+
+loaderUtils.stringifyRequest(this, "test");
+// "\"test\""
+
+loaderUtils.stringifyRequest(this, "test/lib/index.js");
+// "\"test/lib/index.js\""
+
+loaderUtils.stringifyRequest(this, "otherLoader?andConfig!test?someConfig");
+// "\"otherLoader?andConfig!test?someConfig\""
+
+loaderUtils.stringifyRequest(this, require.resolve("test"));
+// "\"../node_modules/some-loader/lib/test.js\""
+
+loaderUtils.stringifyRequest(this, "C:\\module\\test.js");
+// "\"../../test.js\"" (on Windows, in case the module and the request are on the same drive)
+
+loaderUtils.stringifyRequest(this, "C:\\module\\test.js");
+// "\"C:\\module\\test.js\"" (on Windows, in case the module and the request are on different drives)
+
+loaderUtils.stringifyRequest(this, "\\\\network-drive\\test.js");
+// "\"\\\\network-drive\\\\test.js\"" (on Windows, in case the module and the request are on different drives)
+```
+
+### `urlToRequest`
+
+Converts some resource URL to a webpack module request.
+
+> i Before call `urlToRequest` you need call `isUrlRequest` to ensure it is requestable url
+
+```javascript
+const url = "path/to/module.js";
+
+if (loaderUtils.isUrlRequest(url)) {
+  // Logic for requestable url
+  const request = loaderUtils.urlToRequest(url);
+} else {
+  // Logic for not requestable url
+}
+```
+
+Simple example:
+
+```javascript
+const url = "path/to/module.js";
+const request = loaderUtils.urlToRequest(url); // "./path/to/module.js"
+```
+
+#### Module URLs
+
+Any URL containing a `~` will be interpreted as a module request. Anything after the `~` will be considered the request path.
+
+```javascript
+const url = "~path/to/module.js";
+const request = loaderUtils.urlToRequest(url); // "path/to/module.js"
+```
+
+#### Root-relative URLs
+
+URLs that are root-relative (start with `/`) can be resolved relative to some arbitrary path by using the `root` parameter:
+
+```javascript
+const url = "/path/to/module.js";
+const root = "./root";
+const request = loaderUtils.urlToRequest(url, root); // "./root/path/to/module.js"
+```
+
+To convert a root-relative URL into a module URL, specify a `root` value that starts with `~`:
+
+```javascript
+const url = "/path/to/module.js";
+const root = "~";
+const request = loaderUtils.urlToRequest(url, root); // "path/to/module.js"
+```
+
+### `interpolateName`
+
+Interpolates a filename template using multiple placeholders and/or a regular expression.
+The template and regular expression are set as query params called `name` and `regExp` on the current loader's context.
+
+```javascript
+const interpolatedName = loaderUtils.interpolateName(loaderContext, name, options);
+```
+
+The following tokens are replaced in the `name` parameter:
+
+* `[ext]` the extension of the resource
+* `[name]` the basename of the resource
+* `[path]` the path of the resource relative to the `context` query parameter or option.
+* `[folder]` the folder the resource is in
+* `[query]` the queryof the resource, i.e. `?foo=bar`
+* `[emoji]` a random emoji representation of `options.content`
+* `[emoji:<length>]` same as above, but with a customizable number of emojis
+* `[contenthash]` the hash of `options.content` (Buffer) (by default it's the hex digest of the md4 hash)
+* `[<hashType>:contenthash:<digestType>:<length>]` optionally one can configure
+  * other `hashType`s, i. e. `sha1`, `md4`, `md5`, `sha256`, `sha512`
+  * other `digestType`s, i. e. `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+  * and `length` the length in chars
+* `[hash]` the hash of `options.content` (Buffer) (by default it's the hex digest of the md4 hash)
+* `[<hashType>:hash:<digestType>:<length>]` optionally one can configure
+  * other `hashType`s, i. e. `sha1`, `md4`, `md5`, `sha256`, `sha512`
+  * other `digestType`s, i. e. `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+  * and `length` the length in chars
+* `[N]` the N-th match obtained from matching the current file name against `options.regExp`
+
+In loader context `[hash]` and `[contenthash]` are the same, but we recommend using `[contenthash]` for avoid misleading.
+

+
+// loaderContext.resourcePath = "/absolute/path/to/app/js/page-home.js"
+loaderUtils.interpolateName(loaderContext, "script-[1].[ext]", { regExp: "page-(.*)\\.js", content: ... });
+// => script-home.js
+
+// loaderContext.resourcePath = "/absolute/path/to/app/js/javascript.js"
+// loaderContext.resourceQuery = "?foo=bar"
+loaderUtils.interpolateName(
+  loaderContext, 
+  (resourcePath, resourceQuery) => { 
+    // resourcePath - `/app/js/javascript.js`
+    // resourceQuery - `?foo=bar`
+
+    return "js/[hash].script.[ext]"; 
+  }, 
+  { content: ... }
+);
+// => js/9473fdd0d880a43c21b7778d34872157.script.js
+```
+
+### `getHashDigest`
+
+``` javascript
+const digestString = loaderUtils.getHashDigest(buffer, hashType, digestType, maxLength);
+```
+
+* `buffer` the content that should be hashed
+* `hashType` one of `sha1`, `md4`, `md5`, `sha256`, `sha512` or any other node.js supported hash type
+* `digestType` one of `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+* `maxLength` the maximum length in chars
