+# webpack-dev-server
+
+Use [webpack](https://webpack.js.org) with a development server that provides
+live reloading. This should be used for **development only**.
+
+It uses [webpack-dev-middleware][middleware-url] under the hood, which provides
+fast in-memory access to the webpack assets.

+
+## Getting Started
+
+First things first, install the module:
+
+```console
+npm install webpack-dev-server --save-dev
+```
+
+or
+
+```console
+yarn add -D webpack-dev-server
+```
+
+or
+
+```console
+pnpm add -D webpack-dev-server
+```
+
+_Note: While you can install and run webpack-dev-server globally, we recommend
+installing it locally. webpack-dev-server will always use a local installation
+over a global one._
+
+## Usage
+
+There are two main, recommended methods of using the module:
+
+### With the CLI
+
+The easiest way to use it is with the [webpack CLI](https://webpack.js.org/api/cli/). In the directory where your
+`webpack.config.js` is, run:
+
+```console
+npx webpack serve
+```
+
+Following options are available with `webpack serve`:
+
+```
+Usage: webpack serve|server|s [entries...] [options]

+```json
+{
+  "scripts": {
+    "serve": "webpack serve"
+  }
+}
+```
+
+And run the following in your terminal/console:
+
+```console
+npm run serve
+```
+
+NPM will automatically refer to the the binary in `node_modules` for you, and
+execute the file or command.
+
+### With the API
+
+While it's recommended to run webpack-dev-server via the CLI, you may also choose to start a server via the API.
+
+See the related [API documentation for `webpack-dev-server`](https://webpack.js.org/api/webpack-dev-server/).
+
+### With TypeScript
+
+If you use TypeScript in the webpack config, you'll need to properly type `devServer` property in order to avoid TS errors (e.g. `'devServer' does not exist in type 'Configuration'`). For that use either:
+
+```ts
+/// <reference path="node_modules/webpack-dev-server/types/lib/Server.d.ts"/>
+import type { Configuration } from "webpack";
+
+// Your logic
+```
+
+Or you can import the type from `webpack-dev-server`, i.e.
+
+```ts
+import type { Configuration as DevServerConfiguration } from "webpack-dev-server";
+import type { Configuration } from "webpack";
+
+const devServer: DevServerConfiguration = {};
+const config: Configuration = { devServer };
+
+// module.exports
+export default config;
+```
+
+### The Result
+
+Either method will start a server instance and begin listening for connections
+from `localhost` on port `8080`.
+
+webpack-dev-server is configured by default to support live-reload of files as
+you edit your assets while the server is running.
+
+See [**the documentation**][docs-url] for more use cases and options.
+
+## Browser Support
+
+While `webpack-dev-server` transpiles the client (browser) scripts to an ES5
+state, the project only officially supports the _last two versions of major
+browsers_. We simply don't have the resources to support every whacky
+browser out there.
+
+If you find a bug with an obscure / old browser, we would actively welcome a
+Pull Request to resolve the bug.
+
+## Support
+
+We do our best to keep issues in the repository focused on bugs, features, and
+needed modifications to the code for the module. Because of that, we ask users
+with general support, "how-to", or "why isn't this working" questions to try one
+of the other support channels that are available.
+
+Your first-stop-shop for support for webpack-dev-server should be the excellent
+[documentation][docs-url] for the module. If you see an opportunity for improvement
+of those docs, please head over to the [webpack.js.org repo][wjo-url] and open a
+pull request.
+
+From there, we encourage users to visit the [webpack Gitter chat][chat-url] and
+talk to the fine folks there. If your quest for answers comes up dry in chat,
+head over to [StackOverflow][stack-url] and do a quick search or open a new
+question. Remember; It's always much easier to answer questions that include your
+`webpack.config.js` and relevant files!
+
+If you're twitter-savvy you can tweet [#webpack][hash-url] with your question
+and someone should be able to reach out and lend a hand.
+
+If you have discovered a :bug:, have a feature suggestion, or would like to see
+a modification, please feel free to create an issue on Github. _Note: The issue
+template isn't optional, so please be sure not to remove it, and please fill it
+out completely._

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).
