- * This method returns a list of URLs to precache, referred to as a "precache

- * @param {string} config.globDirectory The local directory you wish to match
- * `globPatterns` against. The path is relative to the current directory.
- *
- * @param {Array<module:workbox-build.ManifestEntry>} [config.additionalManifestEntries]
- * A list of entries to be precached, in addition to any entries that are
- * generated as part of the build configuration.
- *
- * @param {RegExp} [config.dontCacheBustURLsMatching] Assets that match this will be
- * assumed to be uniquely versioned via their URL, and exempted from the normal
- * HTTP cache-busting that's done when populating the precache. While not
- * required, it's recommended that if your existing build process already
- * inserts a `[hash]` value into each filename, you provide a RegExp that will
- * detect that, as it will reduce the bandwidth consumed when precaching.
- *
- * @param {boolean} [config.globFollow=true] Determines whether or not symlinks
- * are followed when generating the precache manifest. For more information, see
- * the definition of `follow` in the `glob`
- * [documentation](https://github.com/isaacs/node-glob#options).
- *
- * @param {Array<string>} [config.globIgnores=['node_modules/**']]
- * A set of patterns matching files to always exclude when generating the
- * precache manifest. For more information, see the definition of `ignore` in the `glob`
- * [documentation](https://github.com/isaacs/node-glob#options).
- *
- * @param {Array<string>} [config.globPatterns=['**.{js,css,html}']]
- * Files matching any of these patterns will be included in the precache
- * manifest. For more information, see the
- * [`glob` primer](https://github.com/isaacs/node-glob#glob-primer).
- *
- * @param {boolean} [config.globStrict=true] If true, an error reading a directory when
- * generating a precache manifest will cause the build to fail. If false, the
- * problematic directory will be skipped. For more information, see the
- * definition of `strict` in the `glob`
- * [documentation](https://github.com/isaacs/node-glob#options).
- *
- * @param {Array<module:workbox-build.ManifestTransform>} [config.manifestTransforms] One or more
- * functions which will be applied sequentially against the generated manifest.
- * If `modifyURLPrefix` or `dontCacheBustURLsMatching` are also specified, their
- * corresponding transformations will be applied first.
- *
- * @param {number} [config.maximumFileSizeToCacheInBytes=2097152] This value can be
- * used to determine the maximum size of files that will be precached. This
- * prevents you from inadvertently precaching very large files that might have
- * accidentally matched one of your patterns.
- *
- * @param {string} [config.mode='production'] If set to 'production', then an
- * optimized service worker bundle that excludes debugging info will be
- * produced. If not explicitly configured here, the `process.env.NODE_ENV` value
- * will be used, and failing that, it will fall back to `'production'`.
- *
- * @param {object<string, string>} [config.modifyURLPrefix] A mapping of prefixes
- * that, if present in an entry in the precache manifest, will be replaced with
- * the corresponding value. This can be used to, for example, remove or add a
- * path prefix from a manifest entry if your web hosting setup doesn't match
- * your local filesystem setup. As an alternative with more flexibility, you can
- * use the `manifestTransforms` option and provide a function that modifies the
- * entries in the manifest using whatever logic you provide.
- *
- * @param {Object} [config.templatedURLs] If a URL is rendered based on some
- * server-side logic, its contents may depend on multiple files or on some other
- * unique string value. The keys in this object are server-rendered URLs. If the
- * values are an array of strings, they will be interpreted as `glob` patterns,
- * and the contents of any files matching the patterns will be used to uniquely
- * version the URL. If used with a single string, it will be interpreted as
- * unique versioning information that you've generated for a given URL.
- *
- * @return {Promise<{count: number, manifestEntries: Array<module:workbox-build.ManifestEntry>, size: number, warnings: Array<string>}>}
- * A promise that resolves once the precache manifest (available in the
- * `manifestEntries` property) has been determined. The `size` property
- * contains the aggregate size of all the precached entries, in bytes, and the
- * `count` property contains the total number of precached entries. Any
- * non-fatal warning messages will be returned via `warnings`.

- * [`glob` primer](https://github.com/isaacs/node-glob#glob-primer).
- *
- * @param {boolean} [config.globStrict=true] If true, an error reading a directory when
- * generating a precache manifest will cause the build to fail. If false, the
- * problematic directory will be skipped. For more information, see the
- * definition of `strict` in the `glob`
- * [documentation](https://github.com/isaacs/node-glob#options).
- *
- * @param  {string} [config.injectionPoint='self.__WB_MANIFEST'] The string to
- * find inside of the `swSrc` file. Once found, it will be replaced by the
- * generated precache manifest.
- *
- * @param {Array<module:workbox-build.ManifestTransform>} [config.manifestTransforms] One or more
- * functions which will be applied sequentially against the generated manifest.
- * If `modifyURLPrefix` or `dontCacheBustURLsMatching` are also specified, their
- * corresponding transformations will be applied first.
- *
- * @param {number} [config.maximumFileSizeToCacheInBytes=2097152] This value can be
- * used to determine the maximum size of files that will be precached. This
- * prevents you from inadvertently precaching very large files that might have
- * accidentally matched one of your patterns.
- *
- * @param {string} [config.mode='production'] If set to 'production', then an
- * optimized service worker bundle that excludes debugging info will be
- * produced. If not explicitly configured here, the `process.env.NODE_ENV` value
- * will be used, and failing that, it will fall back to `'production'`.
- *
- * @param {object<string, string>} [config.modifyURLPrefix] A mapping of prefixes
- * that, if present in an entry in the precache manifest, will be replaced with
- * the corresponding value. This can be used to, for example, remove or add a
- * path prefix from a manifest entry if your web hosting setup doesn't match
- * your local filesystem setup. As an alternative with more flexibility, you can
- * use the `manifestTransforms` option and provide a function that modifies the
- * entries in the manifest using whatever logic you provide.
- *
- * @param {Object} [config.templatedURLs] If a URL is rendered based on some
- * server-side logic, its contents may depend on multiple files or on some other
- * unique string value. The keys in this object are server-rendered URLs. If the
- * values are an array of strings, they will be interpreted as `glob` patterns,
- * and the contents of any files matching the patterns will be used to uniquely
- * version the URL. If used with a single string, it will be interpreted as
- * unique versioning information that you've generated for a given URL.
- *
- * @return {Promise<{count: number, filePaths: Array<string>, size: number, warnings: Array<string>}>}
- * A promise that resolves once the service worker and related files
- * (indicated by `filePaths`) has been written to `swDest`. The `size` property
- * contains the aggregate size of all the precached entries, in bytes, and the
- * `count` property contains the total number of precached entries. Any
- * non-fatal warning messages will be returned via `warnings`.

-/**
- * A `ManifestTransform` function can be used to modify the modify the `url` or
- * `revision` properties of some or all of the
- * {@link module:workbox-build.ManifestEntry|ManifestEntries} in the manifest.
- *
- * Deleting the `revision` property of an entry will cause
- * the corresponding `url` to be precached without cache-busting parameters
- * applied, which is to say, it implies that the URL itself contains
- * proper versioning info. If the `revision` property is present, it must be
- * set to a string.
- *
- * @example A transformation that prepended the origin of a CDN for any
- * URL starting with '/assets/' could be implemented as:
- *
- * const cdnTransform = async (manifestEntries) => {
- *   const manifest = manifestEntries.map(entry => {
- *     const cdnOrigin = 'https://example.com';
- *     if (entry.url.startsWith('/assets/')) {
- *       entry.url = cdnOrigin + entry.url;
- *     }
- *     return entry;
- *   });
- *   return {manifest, warnings: []};
- * };
- *
- * @example A transformation that nulls the revision field when the
- * URL contains an 8-character hash surrounded by '.', indicating that it
- * already contains revision information:
- *
- * const removeRevisionTransform = async (manifestEntries) => {
- *   const manifest = manifestEntries.map(entry => {
- *     const hashRegExp = /\.\w{8}\./;
- *     if (entry.url.match(hashRegExp)) {
- *       entry.revision = null;
- *     }
- *     return entry;
- *   });
- *   return {manifest, warnings: []};
- * };
- *
- * @callback ManifestTransform
- * @param {Array<module:workbox-build.ManifestEntry>} manifestEntries The full
- * array of entries, prior to the current transformation.
- * @param {Object} [compilation] When used in the webpack plugins, this param
- * will be set to the current `compilation`.
- * @return {Promise<module:workbox-build.ManifestTransformResult>}
- * The array of entries with the transformation applied, and optionally, any
- * warnings that should be reported back to the build tool.
- *
- * @memberof module:workbox-build

-Node.js: fs-extra
-=================
-
-`fs-extra` adds file system methods that aren't included in the native `fs` module and adds promise support to the `fs` methods. It also uses [`graceful-fs`](https://github.com/isaacs/node-graceful-fs) to prevent `EMFILE` errors. It should be a drop in replacement for `fs`.

-[![JavaScript Style Guide](https://img.shields.io/badge/code_style-standard-brightgreen.svg)](https://standardjs.com)
-
-Why?
-----
-
-I got tired of including `mkdirp`, `rimraf`, and `ncp` in most of my projects.
-
-
-
-
-Installation
-------------
-
-    npm install fs-extra
-
-
-
-Usage
------
-
-`fs-extra` is a drop in replacement for native `fs`. All methods in `fs` are attached to `fs-extra`. All `fs` methods return promises if the callback isn't passed.
-
-You don't ever need to include the original `fs` module again:
-
-```js
-const fs = require('fs') // this is no longer necessary
-```
-
-you can now do this:
-
-```js
-const fs = require('fs-extra')
-```
-
-or if you prefer to make it clear that you're using `fs-extra` and not `fs`, you may want
-to name your `fs` variable `fse` like so:
-
-```js
-const fse = require('fs-extra')
-```
-
-you can also keep both, but it's redundant:
-
-```js
-const fs = require('fs')
-const fse = require('fs-extra')
-```
-
-Sync vs Async vs Async/Await
--------------
-Most methods are async by default. All async methods will return a promise if the callback isn't passed.
-
-Sync methods on the other hand will throw if an error occurs.
-
-Also Async/Await will throw an error if one occurs.
-
-Example:
-
-```js
-const fs = require('fs-extra')
-
-// Async with promises:
-fs.copy('/tmp/myfile', '/tmp/mynewfile')
-  .then(() => console.log('success!'))
-  .catch(err => console.error(err))
-
-// Async with callbacks:
-fs.copy('/tmp/myfile', '/tmp/mynewfile', err => {
-  if (err) return console.error(err)
-  console.log('success!')
-})
-
-// Sync:
-try {
-  fs.copySync('/tmp/myfile', '/tmp/mynewfile')
-  console.log('success!')
-} catch (err) {
-  console.error(err)
-}
-
-// Async/Await:
-async function copyFiles () {
-  try {
-    await fs.copy('/tmp/myfile', '/tmp/mynewfile')
-    console.log('success!')
-  } catch (err) {
-    console.error(err)
-  }
-}
-
-copyFiles()
-```

-
-
-**NOTE:** You can still use the native Node.js methods. They are promisified and copied over to `fs-extra`. See [notes on `fs.read()` & `fs.write()`](docs/fs-read-write.md)
-
-### What happened to `walk()` and `walkSync()`?
-
-They were removed from `fs-extra` in v2.0.0. If you need the functionality, `walk` and `walkSync` are available as separate packages, [`klaw`](https://github.com/jprichardson/node-klaw) and [`klaw-sync`](https://github.com/manidlou/node-klaw-sync).
-
-
-Third Party
------------
-
-
-### TypeScript
-
-If you like TypeScript, you can use `fs-extra` with it: https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/fs-extra
-
-
-### File / Directory Watching
-
-If you want to watch for changes to files or directories, then you should use [chokidar](https://github.com/paulmillr/chokidar).
-
-### Obtain Filesystem (Devices, Partitions) Information
-
-[fs-filesystem](https://github.com/arthurintelligence/node-fs-filesystem) allows you to read the state of the filesystem of the host on which it is run. It returns information about both the devices and the partitions (volumes) of the system.
-
-### Misc.
-
-- [fs-extra-debug](https://github.com/jdxcode/fs-extra-debug) - Send your fs-extra calls to [debug](https://npmjs.org/package/debug).
-- [mfs](https://github.com/cadorn/mfs) - Monitor your fs-extra calls.

-Hacking on fs-extra
--------------------
-
-Wanna hack on `fs-extra`? Great! Your help is needed! [fs-extra is one of the most depended upon Node.js packages](http://nodei.co/npm/fs-extra.png?downloads=true&downloadRank=true&stars=true). This project
-uses [JavaScript Standard Style](https://github.com/feross/standard) - if the name or style choices bother you,
-you're gonna have to get over it :) If `standard` is good enough for `npm`, it's good enough for `fs-extra`.
-
-[![js-standard-style](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
-
-What's needed?
-- First, take a look at existing issues. Those are probably going to be where the priority lies.
-- More tests for edge cases. Specifically on different platforms. There can never be enough tests.
-- Improve test coverage. See coveralls output for more info.
-
-Note: If you make any big changes, **you should definitely file an issue for discussion first.**
-
-### Running the Test Suite
-
-fs-extra contains hundreds of tests.
-
-- `npm run lint`: runs the linter ([standard](http://standardjs.com/))
-- `npm run unit`: runs the unit tests
-- `npm test`: runs both the linter and the tests
-
-
-### Windows
-
-If you run the tests on the Windows and receive a lot of symbolic link `EPERM` permission errors, it's
-because on Windows you need elevated privilege to create symbolic links. You can add this to your Windows's
-account by following the instructions here: http://superuser.com/questions/104845/permission-to-make-symbolic-links-in-windows-7
-However, I didn't have much luck doing this.
-
-Since I develop on Mac OS X, I use VMWare Fusion for Windows testing. I create a shared folder that I map to a drive on Windows.
-I open the `Node.js command prompt` and run as `Administrator`. I then map the network drive running the following command:
-
-    net use z: "\\vmware-host\Shared Folders"
-
-I can then navigate to my `fs-extra` directory and run the tests.
-
-
-Naming
-------
-
-I put a lot of thought into the naming of these functions. Inspired by @coolaj86's request. So he deserves much of the credit for raising the issue. See discussion(s) here:
-
-* https://github.com/jprichardson/node-fs-extra/issues/2
-* https://github.com/flatiron/utile/issues/11
-* https://github.com/ryanmcgrath/wrench-js/issues/29
-* https://github.com/substack/node-mkdirp/issues/17
-
-First, I believe that in as many cases as possible, the [Node.js naming schemes](http://nodejs.org/api/fs.html) should be chosen. However, there are problems with the Node.js own naming schemes.
-
-For example, `fs.readFile()` and `fs.readdir()`: the **F** is capitalized in *File* and the **d** is not capitalized in *dir*. Perhaps a bit pedantic, but they should still be consistent. Also, Node.js has chosen a lot of POSIX naming schemes, which I believe is great. See: `fs.mkdir()`, `fs.rmdir()`, `fs.chown()`, etc.
-
-We have a dilemma though. How do you consistently name methods that perform the following POSIX commands: `cp`, `cp -r`, `mkdir -p`, and `rm -rf`?
-
-My perspective: when in doubt, err on the side of simplicity. A directory is just a hierarchical grouping of directories and files. Consider that for a moment. So when you want to copy it or remove it, in most cases you'll want to copy or remove all of its contents. When you want to create a directory, if the directory that it's suppose to be contained in does not exist, then in most cases you'll want to create that too.
-
-So, if you want to remove a file or a directory regardless of whether it has contents, just call `fs.remove(path)`. If you want to copy a file or a directory whether it has contents, just call `fs.copy(source, destination)`. If you want to create a directory regardless of whether its parent directories exist, just call `fs.mkdirs(path)` or `fs.mkdirp(path)`.

-/**
- * Function that returns two types of paths, one relative to symlink, and one
- * relative to the current working directory. Checks if path is absolute or
- * relative. If the path is relative, this function checks if the path is
- * relative to symlink or relative to current working directory. This is an
- * initiative to find a smarter `srcpath` to supply when building symlinks.
- * This allows you to determine which path to use out of one of three possible
- * types of source paths. The first is an absolute path. This is detected by
- * `path.isAbsolute()`. When an absolute path is provided, it is checked to
- * see if it exists. If it does it's used, if not an error is returned
- * (callback)/ thrown (sync). The other two options for `srcpath` are a
- * relative url. By default Node's `fs.symlink` works by creating a symlink
- * using `dstpath` and expects the `srcpath` to be relative to the newly
- * created symlink. If you provide a `srcpath` that does not exist on the file
- * system it results in a broken symlink. To minimize this, the function
- * checks to see if the 'relative to symlink' source file exists, and if it
- * does it will use it. If it does not, it checks if there's a file that
- * exists that is relative to the current working directory, if does its used.
- * This preserves the expectations of the original fs.symlink spec and adds
- * the ability to pass in `relative to current working direcotry` paths.
