+# Class: RetryHandler
+
+Extends: `undici.DispatcherHandlers`
+
+A handler class that implements the retry logic for a request.
+
+## `new RetryHandler(dispatchOptions, retryHandlers, [retryOptions])`
+
+Arguments:
+
+- **options** `Dispatch.DispatchOptions & RetryOptions` (required) - It is an intersection of `Dispatcher.DispatchOptions` and `RetryOptions`.
+- **retryHandlers** `RetryHandlers` (required) - Object containing the `dispatch` to be used on every retry, and `handler` for handling the `dispatch` lifecycle.
+
+Returns: `retryHandler`
+
+### Parameter: `Dispatch.DispatchOptions & RetryOptions`
+
+Extends: [`Dispatch.DispatchOptions`](Dispatcher.md#parameter-dispatchoptions).
+
+#### `RetryOptions`
+
+- **retry** `(err: Error, context: RetryContext, callback: (err?: Error | null) => void) => void` (optional) - Function to be called after every retry. It should pass error if no more retries should be performed.
+- **maxRetries** `number` (optional) - Maximum number of retries. Default: `5`
+- **maxTimeout** `number` (optional) - Maximum number of milliseconds to wait before retrying. Default: `30000` (30 seconds)
+- **minTimeout** `number` (optional) - Minimum number of milliseconds to wait before retrying. Default: `500` (half a second)
+- **timeoutFactor** `number` (optional) - Factor to multiply the timeout by for each retry attempt. Default: `2`
+- **retryAfter** `boolean` (optional) - It enables automatic retry after the `Retry-After` header is received. Default: `true`
+-
+- **methods** `string[]` (optional) - Array of HTTP methods to retry. Default: `['GET', 'PUT', 'HEAD', 'OPTIONS', 'DELETE']`
+- **statusCodes** `number[]` (optional) - Array of HTTP status codes to retry. Default: `[429, 500, 502, 503, 504]`
+- **errorCodes** `string[]` (optional) - Array of Error codes to retry. Default: `['ECONNRESET', 'ECONNREFUSED', 'ENOTFOUND', 'ENETDOWN','ENETUNREACH', 'EHOSTDOWN',
+
+**`RetryContext`**
+
+- `state`: `RetryState` - Current retry state. It can be mutated.
+- `opts`: `Dispatch.DispatchOptions & RetryOptions` - Options passed to the retry handler.
+
+### Parameter `RetryHandlers`
+
+- **dispatch** `(options: Dispatch.DispatchOptions, handlers: Dispatch.DispatchHandlers) => Promise<Dispatch.DispatchResponse>` (required) - Dispatch function to be called after every retry.
+- **handler** Extends [`Dispatch.DispatchHandlers`](Dispatcher.md#dispatcherdispatchoptions-handler) (required) - Handler function to be called after the request is successful or the retries are exhausted.
+
+Examples:
+
+```js
+const client = new Client(`http://localhost:${server.address().port}`);
+const chunks = [];
+const handler = new RetryHandler(
+  {
+    ...dispatchOptions,
+    retryOptions: {
+      // custom retry function
+      retry: function (err, state, callback) {
+        counter++;
+
+        if (err.code && err.code === "UND_ERR_DESTROYED") {
+          callback(err);
+          return;
+        }
+
+        if (err.statusCode === 206) {
+          callback(err);
+          return;
+        }
+
+        setTimeout(() => callback(null), 1000);
+      },
+    },
+  },
+  {
+    dispatch: (...args) => {
+      return client.dispatch(...args);
+    },
+    handler: {
+      onConnect() {},
+      onBodySent() {},
+      onHeaders(status, _rawHeaders, resume, _statusMessage) {
+        // do something with headers
+      },
+      onData(chunk) {
+        chunks.push(chunk);
+        return true;
+      },
+      onComplete() {},
+      onError() {
+        // handle error properly
+      },
+    },
+  }
+);
+```
+
+#### Example - Basic RetryHandler with defaults
+
+```js
+const client = new Client(`http://localhost:${server.address().port}`);
+const handler = new RetryHandler(dispatchOptions, {
+  dispatch: client.dispatch.bind(client),
+  handler: {
+    onConnect() {},
+    onBodySent() {},
+    onHeaders(status, _rawHeaders, resume, _statusMessage) {},
+    onData(chunk) {},
+    onComplete() {},
+    onError(err) {},
+  },
+});
+```
