2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   #[cfg_attr(mobile, tauri::mobile_entry_point)]
   pub fn run() {
     tauri::Builder::default()
       .plugin(tauri_plugin_upload::init())

         .expect("error while running tauri application");
   }

3. Install the JavaScript Guest bindings using your preferred JavaScript package manager:

   npm

   npm install @tauri-apps/plugin-upload

   yarn

   yarn add @tauri-apps/plugin-upload

   pnpm

   pnpm add @tauri-apps/plugin-upload

   deno

   deno add npm:@tauri-apps/plugin-upload

   bun

   bun add @tauri-apps/plugin-upload

Usage

Once you’ve completed the registration and setup process for the plugin, you can access all of its APIs through the JavaScript guest bindings.

Here’s an example of how you can use the plugin to upload and download files:

import { upload } from '@tauri-apps/plugin-upload';
// when using `"withGlobalTauri": true`, you may use
// const { upload } = window.__TAURI__.upload;

upload(
  'https://example.com/file-upload',
  './path/to/my/file.txt',
  ({ progress, total }) =>
    console.log(`Uploaded ${progress} of ${total} bytes`), // a callback that will be called with the upload progress
  { 'Content-Type': 'text/plain' } // optional headers to send with the request
);

import { download } from '@tauri-apps/plugin-upload';
// when using `"withGlobalTauri": true`, you may use
// const { download } = window.__TAURI__.upload;

download(
  'https://example.com/file-download-link',
  './path/to/save/my/file.txt',
  ({ progress, total }) =>
    console.log(`Downloaded ${progress} of ${total} bytes`), // a callback that will be called with the download progress
  { 'Content-Type': 'text/plain' } // optional headers to send with the request
);
