+# EventSource
+
+Undici exposes a WHATWG spec-compliant implementation of [EventSource](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)
+for [Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events).
+
+## Instantiating EventSource
+
+Undici exports a EventSource class. You can instantiate the EventSource as
+follows:
+
+```mjs
+import { EventSource } from 'undici'
+
+const evenSource = new EventSource('http://localhost:3000')
+evenSource.onmessage = (event) => {
+  console.log(event.data)
+}
+```
+
+More information about the EventSource API can be found on
+[MDN](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

+# Class: RedirectHandler
+
+A class that handles redirection logic for HTTP requests.
+
+## `new RedirectHandler(dispatch, maxRedirections, opts, handler, redirectionLimitReached)`
+
+Arguments:
+
+- **dispatch** `function` - The dispatch function to be called after every retry.
+- **maxRedirections** `number` - Maximum number of redirections allowed.
+- **opts** `object` - Options for handling redirection.
+- **handler** `object` - An object containing handlers for different stages of the request lifecycle.
+- **redirectionLimitReached** `boolean` (default: `false`) - A flag that the implementer can provide to enable or disable the feature. If set to `false`, it indicates that the caller doesn't want to use the feature and prefers the old behavior.
+
+Returns: `RedirectHandler`
+
+### Parameters
+
+- **dispatch** `(options: Dispatch.DispatchOptions, handlers: Dispatch.DispatchHandlers) => Promise<Dispatch.DispatchResponse>` (required) - Dispatch function to be called after every redirection.
+- **maxRedirections** `number` (required) - Maximum number of redirections allowed.
+- **opts** `object` (required) - Options for handling redirection.
+- **handler** `object` (required) - Handlers for different stages of the request lifecycle.
+- **redirectionLimitReached** `boolean` (default: `false`) - A flag that the implementer can provide to enable or disable the feature. If set to `false`, it indicates that the caller doesn't want to use the feature and prefers the old behavior.
+
+### Properties
+
+- **location** `string` - The current redirection location.
+- **abort** `function` - The abort function.
+- **opts** `object` - The options for handling redirection.
+- **maxRedirections** `number` - Maximum number of redirections allowed.
+- **handler** `object` - Handlers for different stages of the request lifecycle.
+- **history** `Array` - An array representing the history of URLs during redirection.
+- **redirectionLimitReached** `boolean` - Indicates whether the redirection limit has been reached.
+
+### Methods
+
+#### `onConnect(abort)`
+
+Called when the connection is established.
+
+Parameters:
+
+- **abort** `function` - The abort function.
+
+#### `onUpgrade(statusCode, headers, socket)`

+
+Parameters:
+
+- **statusCode** `number` - The HTTP status code.
+- **headers** `object` - The headers received in the response.

+- **headers** `object` - The headers received in the response.
+- **resume** `function` - The resume function.
+- **statusText** `string` - The status text.
+
+#### `onData(chunk)`
+
+Called when data is received.
+
+Parameters:
+
+- **chunk** `Buffer` - The data chunk received.
+
+#### `onComplete(trailers)`
