How to Upload File/Image to Server with Form Data in React Native

In this video, I’ll show you how to Upload File/Image to Server with Form Data in React Native. This example will cover how to pick any file from the file system and upload it to the server.we are going to use React native Fetch request to send the file to the server. and we are using Form data to upload files to the server.
The FormData interface provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to "multipart/form-data"
Create FormData by creating an object and appending the values you want to send to the server
const data = new FormData();
data.append('name', 'Image Upload');
data.append('file_attachment', fileToUpload);
the second value of FormData.append can be a Blob, File, or a string, if neither, the value is converted to a string

You mentioned to stringify object when sending data but you are sending object without stringifying and it still works. How?

[@rtdev8512]

you no need to stringify file object, stringify only needed if you send non file object
