-# [Please visit our Github Page for latest document](https://github.com/wkh237/react-native-fetch-blob)

 ## Features
 - Transfer data directly from/to storage without BASE64 bridging
 - File API supports normal files, Asset files, and CameraRoll files
     })
 ```
 
+In `0.9.6`, you can specify an optional first argument which contains `count` and `interval` to limit progress event frequency (this will be done in native context in order to reduce RCT bridge overhead). Notice that `count` argument will not work if the server does not provide response content length.
+
+
+```js
+  RNFetchBlob.fetch('POST', 'http://www.example.com/upload', {
+      ... some headers,
+      'Content-Type' : 'octet-stream'
+    }, base64DataString)
+    // listen to upload progress event, emit every 250ms
+    .uploadProgress({ interval : 250 },(written, total) => {
+        console.log('uploaded', written / total)
+    })
+    // listen to download progress event, every 10%
+    .progress({ count : 10 }, (received, total) => {
+        console.log('progress', received / total)
+    })
+    .then((resp) => {
+      // ...
+    })
+    .catch((err) => {
+      // ...
+    })
+```
