FormData

Upload files and form fields using FormData.

File upload example

import { fetch } from 'react-native-nitro-fetch';

const fd = new FormData();
fd.append('username', 'nitro_user');
fd.append('avatar', {
  uri: 'file:///path/to/photo.jpg',
  type: 'image/jpeg',
  name: 'avatar.jpg',
});

const res = await fetch('https://httpbin.org/post', {
  method: 'POST',
  body: fd,
});
const json = await res.json();

Text fields

const fd = new FormData();
fd.append('name', 'John');
fd.append('email', 'john@example.com');

const res = await fetch('https://httpbin.org/post', {
  method: 'POST',
  body: fd,
});

note

The FormData API follows the standard browser interface. File objects use the React Native convention with uri, type, and name fields.
