+
+[![codecov](https://codecov.io/gh/vercel/serve-handler/branch/main/graph/badge.svg)](https://codecov.io/gh/vercel/serve-handler)
+[![install size](https://packagephobia.now.sh/badge?p=serve-handler)](https://packagephobia.now.sh/result?p=serve-handler)
+
+This package represents the core of [serve](https://github.com/vercel/serve). It can be plugged into any HTTP server and is responsible for routing requests and handling responses.
+
+In order to customize the default behaviour, you can also pass custom routing rules, provide your own methods for interacting with the file system and much more.
+
+## Usage
+
+Get started by installing the package using [yarn](https://yarnpkg.com/lang/en/):
+
+```sh
+yarn add serve-handler
+```
+
+You can also use [npm](https://www.npmjs.com/) instead, if you'd like:
+
+```sh
+npm install serve-handler
+```
+
+Next, add it to your HTTP server. Here's an example using [micro](https://github.com/vercel/micro):
+
+```js
+const handler = require('serve-handler');
+
+module.exports = async (request, response) => {
+  await handler(request, response);
+};
+```
+
+That's it! :tada:
+
+## Options
+
+If you want to customize the package's default behaviour, you can use the third argument of the function call to pass any of the configuration options listed below. Here's an example:
+
+```js
+await handler(request, response, {
+  cleanUrls: true
+});
+```
+
+You can use any of the following options:
+
+| Property                                             | Description                                                           |
+|------------------------------------------------------|-----------------------------------------------------------------------|
+| [`public`](#public-string)                           | Set a sub directory to be served                                      |
+| [`cleanUrls`](#cleanurls-booleanarray)               | Have the `.html` extension stripped from paths                        |
+| [`rewrites`](#rewrites-array)                        | Rewrite paths to different paths                                      |
+| [`redirects`](#redirects-array)                      | Forward paths to different paths or external URLs                     |
+| [`headers`](#headers-array)                          | Set custom headers for specific paths                                 |
+| [`directoryListing`](#directorylisting-booleanarray) | Disable directory listing or restrict it to certain paths             |
+| [`unlisted`](#unlisted-array)                        | Exclude paths from the directory listing                              |
+| [`trailingSlash`](#trailingslash-boolean)            | Remove or add trailing slashes to all paths                           |
+| [`renderSingle`](#rendersingle-boolean)              | If a directory only contains one file, render it                      |
+| [`symlinks`](#symlinks-boolean)                      | Resolve symlinks instead of rendering a 404 error                     |
+| [`etag`](#etag-boolean)                              | Calculate a strong `ETag` response header, instead of `Last-Modified` |
+
+### public (String)
+
+By default, the current working directory will be served. If you only want to serve a specific path, you can use this options to pass an absolute path or a custom directory to be served relative to the current working directory.
+
+For example, if serving a [Jekyll](https://jekyllrb.com/) app, it would look like this:
+
+```json
+{
+  "public": "_site"
+}
+```
+
+Using absolute path:
+
+```json
+{
+  "public": "/path/to/your/_site"
+}
+```
+
+**NOTE:** The path cannot contain globs or regular expressions.
+
+### cleanUrls (Boolean|Array)
+
+By default, all `.html` files can be accessed without their extension.
+
+If one of these extensions is used at the end of a filename, it will automatically perform a redirect with status code [301](https://en.wikipedia.org/wiki/HTTP_301) to the same path, but with the extension dropped.
+
+You can disable the feature like follows:
+
+```json
+{
+  "cleanUrls": false
+}
+```
+
+However, you can also restrict it to certain paths:
+
+```json
+{
+  "cleanUrls": [
+    "/app/**",
+    "/!components/**"
+  ]
+}
+```
+
+**NOTE:** The paths can only contain globs that are matched using [minimatch](https://github.com/isaacs/minimatch).
+
+### rewrites (Array)
+
+If you want your visitors to receive a response under a certain path, but actually serve a completely different one behind the curtains, this option is what you need.
+
+It's perfect for [single page applications](https://en.wikipedia.org/wiki/Single-page_application) (SPAs), for example:
+
+```json
+{
+  "rewrites": [
+    { "source": "app/**", "destination": "/index.html" },
+    { "source": "projects/*/edit", "destination": "/edit-project.html" }
+  ]
+}
+```
+
+You can also use so-called "routing segments" as follows:
+
+```json
+{
+  "rewrites": [
+    { "source": "/projects/:id/edit", "destination": "/edit-project-:id.html" },
+  ]
+}
+```
+
+Now, if a visitor accesses `/projects/123/edit`, it will respond with the file `/edit-project-123.html`.
+
+**NOTE:** The paths can contain globs (matched using [minimatch](https://github.com/isaacs/minimatch)) or regular expressions (match using [path-to-regexp](https://github.com/pillarjs/path-to-regexp)).
+
+### redirects (Array)
+
+In order to redirect visits to a certain path to a different one (or even an external URL), you can use this option:
+
+```json
+{
+  "redirects": [
+    { "source": "/from", "destination": "/to" },
+    { "source": "/old-pages/**", "destination": "/home" }
+  ]
+}
+```
+
+By default, all of them are performed with the status code [301](https://en.wikipedia.org/wiki/HTTP_301), but this behavior can be adjusted by setting the `type` property directly on the object (see below).
+
+Just like with [rewrites](#rewrites-array), you can also use routing segments:
+
+```json
+{
+  "redirects": [
+    { "source": "/old-docs/:id", "destination": "/new-docs/:id" },
+    { "source": "/old", "destination": "/new", "type": 302 }
+  ]
+}
+```
+
+In the example above, `/old-docs/12` would be forwarded to `/new-docs/12` with status code [301](https://en.wikipedia.org/wiki/HTTP_301). In addition `/old` would be forwarded to `/new` with status code [302](https://en.wikipedia.org/wiki/HTTP_302).
+
+**NOTE:** The paths can contain globs (matched using [minimatch](https://github.com/isaacs/minimatch)) or regular expressions (match using [path-to-regexp](https://github.com/pillarjs/path-to-regexp)).
+
+### headers (Array)
+
+Allows you to set custom headers (and overwrite the default ones) for certain paths:
+
+```json
+{
+  "headers": [
+    {
+      "source" : "**/*.@(jpg|jpeg|gif|png)",
+      "headers" : [{
+        "key" : "Cache-Control",
+        "value" : "max-age=7200"
+      }]
+    }, {
+      "source" : "404.html",
+      "headers" : [{
+        "key" : "Cache-Control",
+        "value" : "max-age=300"
+      }]
+    }
+  ]
+}
+```
+
+If you define the `ETag` header for a path, the handler will automatically reply with status code `304` for that path if a request comes in with a matching `If-None-Match` header.
+
+If you set a header `value` to `null` it removes any previous defined header with the same key.
+
+**NOTE:** The paths can only contain globs that are matched using [minimatch](https://github.com/isaacs/minimatch).
+
+### directoryListing (Boolean|Array)
+
+For paths are not files, but directories, the package will automatically render a good-looking list of all the files and directories contained inside that directory.
+
+If you'd like to disable this for all paths, set this option to `false`. Furthermore, you can also restrict it to certain directory paths if you want:
+
+```json
+{
+  "directoryListing": [
+    "/assets/**",
+    "/!assets/private"
+  ]
+}
+```
+
+**NOTE:** The paths can only contain globs that are matched using [minimatch](https://github.com/isaacs/minimatch).
+
+### unlisted (Array)
+
+In certain cases, you might not want a file or directory to appear in the directory listing. In these situations, there are two ways of solving this problem.
+
+Either you disable the directory listing entirely (like shown [here](#directorylisting-booleanarray)), or you exclude certain paths from those listings by adding them all to this config property.
+
+```json
+{
+  "unlisted": [
+    ".DS_Store",
+    ".git"
+  ]
+}
+```
+
+The items shown above are excluded from the directory listing by default.
+
+**NOTE:** The paths can only contain globs that are matched using [minimatch](https://github.com/isaacs/minimatch).
+
+### trailingSlash (Boolean)
+
+By default, the package will try to make assumptions for when to add trailing slashes to your URLs or not. If you want to remove them, set this property to `false` and `true` if you want to force them on all URLs:
+
+```js
+{
+  "trailingSlash": true
+}
+```
+
+With the above config, a request to `/test` would now result in a [301](https://en.wikipedia.org/wiki/HTTP_301) redirect to `/test/`.
+
+### renderSingle (Boolean)
+
+Sometimes you might want to have a directory path actually render a file, if the directory only contains one. This is only useful for any files that are not `.html` files (for those, [`cleanUrls`](#cleanurls-booleanarray) is faster).
+
+This is disabled by default and can be enabled like this:
+
+```js
+{
+  "renderSingle": true
+}
+```
+
+After that, if you access your directory `/test` (for example), you will see an image being rendered if the directory contains a single image file.
+
+### symlinks (Boolean)
+
+For security purposes, symlinks are disabled by default. If `serve-handler` encounters a symlink, it will treat it as if it doesn't exist in the first place. In turn, a 404 error is rendered for that path.
+
+However, this behavior can easily be adjusted:
+
+```js
+{
+  "symlinks": true
+}
+```
+
+Once this property is set as shown above, all symlinks will automatically be resolved to their targets.
+
+### etag (Boolean)
+
+HTTP response headers will contain a strong [`ETag`][etag] response header, instead of a [`Last-Modified`][last-modified] header. Opt-in because calculating the hash value may be computationally expensive for large files.
+
+Sending an `ETag` header is disabled by default and can be enabled like this:
+
+```js
+{
+  "etag": true
+}
+```
+
+## Error templates
+
+The handler will automatically determine the right error format if one occurs and then sends it to the client in that format.
+
+Furthermore, this allows you to not just specifiy an error template for `404` errors, but also for all other errors that can occur (e.g. `400` or `500`).
+
+Just add a `<status-code>.html` file to the root directory and you're good.
+
+## Middleware
+
+If you want to replace the methods the package is using for interacting with the file system and sending responses, you can pass them as the fourth argument to the function call.
+
+These are the methods used by the package (they can all return a `Promise` or be asynchronous):
+
+```js
+await handler(request, response, undefined, {
+  lstat(path) {},
+  realpath(path) {},
+  createReadStream(path, config) {}
+  readdir(path) {},
+  sendError(absolutePath, response, acceptsJSON, root, handlers, config, error) {}
+});
+```
+
+**NOTE:** It's important that – for native methods like `createReadStream` – all arguments are passed on to the native call.

+
+## Installation
+
+```
+npm install path-to-regexp --save
+```
+
+## Usage
+
+```javascript
+var pathToRegexp = require('path-to-regexp')
+
+// pathToRegexp(path, keys?, options?)
+// pathToRegexp.parse(path)
+// pathToRegexp.compile(path)
+```
+
+- **path** A string, array of strings, or a regular expression.
+- **keys** An array to be populated with the keys found in the path.
+- **options**
+  - **sensitive** When `true` the route will be case sensitive. (default: `false`)
+  - **strict** When `false` the trailing slash is optional. (default: `false`)
+  - **end** When `false` the path will match at the beginning. (default: `true`)
+  - Advanced options (use for non-pathname strings, e.g. host names):
+    - **delimiter** The default delimiter for segments. (default: `'/'`)
+    - **endsWith** Optional character, or list of characters, to treat as "end" characters.
+    - **delimiters** List of characters to consider delimiters when parsing. (default: `'./'`)
+
+```javascript
+var keys = []
+var re = pathToRegexp('/foo/:bar', keys)
+// re = /^\/foo\/([^\/]+?)\/?$/i
+// keys = [{ name: 'bar', prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '[^\\/]+?' }]
+```
+
+**Please note:** The `RegExp` returned by `path-to-regexp` is intended for ordered data (e.g. pathnames, hostnames). It does not handle arbitrary data (e.g. query strings, URL fragments, JSON, etc).
+
+### Parameters
+
+The path argument is used to define parameters and populate the list of keys.
+
+#### Named Parameters
+
+Named parameters are defined by prefixing a colon to the parameter name (`:foo`). By default, the parameter will match until the following path segment.
+
+```js
+var re = pathToRegexp('/:foo/:bar')
+// keys = [{ name: 'foo', prefix: '/', ... }, { name: 'bar', prefix: '/', ... }]
+
+re.exec('/test/route')
+//=> ['/test/route', 'test', 'route']
+```
+
+**Please note:** Parameter names must be made up of "word characters" (`[A-Za-z0-9_]`).
+
+#### Parameter Modifiers
+
+##### Optional
+
+Parameters can be suffixed with a question mark (`?`) to make the parameter optional.
+
+```js
+var re = pathToRegexp('/:foo/:bar?')
+// keys = [{ name: 'foo', ... }, { name: 'bar', delimiter: '/', optional: true, repeat: false }]
+
+re.exec('/test')
+//=> ['/test', 'test', undefined]
+
+re.exec('/test/route')
+//=> ['/test', 'test', 'route']
+```
+
+**Tip:** If the parameter is the _only_ value in the segment, the prefix is also optional.
+
+##### Zero or more
+
+Parameters can be suffixed with an asterisk (`*`) to denote a zero or more parameter matches. The prefix is taken into account for each match.
+
+```js
+var re = pathToRegexp('/:foo*')
+// keys = [{ name: 'foo', delimiter: '/', optional: true, repeat: true }]
+
+re.exec('/')
+//=> ['/', undefined]
+
+re.exec('/bar/baz')
+//=> ['/bar/baz', 'bar/baz']
+```
+
+##### One or more
+
+Parameters can be suffixed with a plus sign (`+`) to denote a one or more parameter matches. The prefix is taken into account for each match.
+
+```js
+var re = pathToRegexp('/:foo+')
+// keys = [{ name: 'foo', delimiter: '/', optional: false, repeat: true }]
+
+re.exec('/')
+//=> null
+
+re.exec('/bar/baz')
+//=> ['/bar/baz', 'bar/baz']
+```
+
+#### Custom Matching Parameters
+
+All parameters can be provided a custom regexp, which overrides the default match (`[^\/]+`). For example, you can match digits in the path:
+
+```js
+var re = pathToRegexp('/icon-:foo(\\d+).png')
+// keys = [{ name: 'foo', ... }]
+
+re.exec('/icon-123.png')
+//=> ['/icon-123.png', '123']
+
+re.exec('/icon-abc.png')
+//=> null
+```
+
+**Please note:** Backslashes need to be escaped with another backslash in strings.
+
+#### Unnamed Parameters
+
+It is possible to write an unnamed parameter that only consists of a matching group. It works the same as a named parameter, except it will be numerically indexed.
+
+```js
+var re = pathToRegexp('/:foo/(.*)')
+// keys = [{ name: 'foo', ... }, { name: 0, ... }]
+
+re.exec('/test/route')
+//=> ['/test/route', 'test', 'route']
+```
+
+### Parse
+
+The parse function is exposed via `pathToRegexp.parse`. This will return an array of strings and keys.
+
+```js
+var tokens = pathToRegexp.parse('/route/:foo/(.*)')
+
+console.log(tokens[0])
+//=> "/route"
+
+console.log(tokens[1])
+//=> { name: 'foo', prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '[^\\/]+?' }
+
+console.log(tokens[2])
+//=> { name: 0, prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '.*' }
+```
+
+**Note:** This method only works with strings.
+
+### Compile ("Reverse" Path-To-RegExp)
+
+Path-To-RegExp exposes a compile function for transforming a string into a valid path.
+
+```js
+var toPath = pathToRegexp.compile('/user/:id')
+
+toPath({ id: 123 }) //=> "/user/123"
+toPath({ id: 'café' }) //=> "/user/caf%C3%A9"
+toPath({ id: '/' }) //=> "/user/%2F"
+
+toPath({ id: ':/' }) //=> "/user/%3A%2F"
+toPath({ id: ':/' }, { encode: (value, token) => value }) //=> "/user/:/"
+
+var toPathRepeated = pathToRegexp.compile('/:segment+')
+
+toPathRepeated({ segment: 'foo' }) //=> "/foo"
+toPathRepeated({ segment: ['a', 'b', 'c'] }) //=> "/a/b/c"
+
+var toPathRegexp = pathToRegexp.compile('/user/:id(\\d+)')
+
+toPathRegexp({ id: 123 }) //=> "/user/123"
+toPathRegexp({ id: '123' }) //=> "/user/123"
+toPathRegexp({ id: 'abc' }) //=> Throws `TypeError`.
+```
+
+**Note:** The generated function will throw on invalid input. It will do all necessary checks to ensure the generated path is valid. This method only works with strings.
+
+### Working with Tokens
+
+Path-To-RegExp exposes the two functions used internally that accept an array of tokens.
+
+* `pathToRegexp.tokensToRegExp(tokens, keys?, options?)` Transform an array of tokens into a matching regular expression.
+* `pathToRegexp.tokensToFunction(tokens)` Transform an array of tokens into a path generator function.
+
+#### Token Information
+
+* `name` The name of the token (`string` for named or `number` for index)
+* `prefix` The prefix character for the segment (`/` or `.`)
+* `delimiter` The delimiter for the segment (same as prefix or `/`)
+* `optional` Indicates the token is optional (`boolean`)
+* `repeat` Indicates the token is repeated (`boolean`)
+* `partial` Indicates this token is a partial path segment (`boolean`)
+* `pattern` The RegExp used to match this token (`string`)
+
+## Compatibility with Express <= 4.x
+
+Path-To-RegExp breaks compatibility with Express <= `4.x`:
+
+* RegExp special characters can only be used in a parameter
+  * Express.js 4.x used all `RegExp` special characters regardless of position - this considered a bug
+* Parameters have suffixes that augment meaning - `*`, `+` and `?`. E.g. `/:user*`
+* No wildcard asterisk (`*`) - use parameters instead (`(.*)`)
+
+## TypeScript
+
+Includes a [`.d.ts`](index.d.ts) file for TypeScript users.
+
