Type `UploadFileOptions` has the structure like this:

```javascript
interface UploadOptions { 
 file: File;
 path: string[]; // Path file
 projectId: string;
 uploadType: UploadType;
 inFolder: boolean;
 exportedKey?: string; // Need if encrypt
 onUploadProgress: () => void; // Progress upload file,
 account: string;
}

export interface UploadFileOptions extends UploadOptions {
 isLargeFile?: boolean; // file's size > 20MB
 chunkSize?: number; // size of each chunk part, recommend 5MB
 uploadUrl?: UploadUrl; // must be ignored when uploading a single file
 callback?: (
   bufferData: BufferData,
   webseed: string[],
   account: string
 ) => void; // callback must be ignored when uploading a single file
}
```

## Example

Example using ReactJS with Axios. Assuming that, you have a project named Project1 with id is “112”, inside this project we have Folder1, and inside Folder1 we have Folder2. So the path is like this: Project1/Folder1/Folder2. The code below shows how to upload a file by encrypt method in Folder2.

```javascript
import {uploadFile as uploadFileLibrary} from "@eueno/lib-browser";

const uploadFile = async () => {
   const file = files[0];
   
   await uploadFileLibrary(token, publicKey, {
     exportedKey,
     file: file,
     path: [“112”, “Folder1”, “Folder2”],
     projectId: “112”,
     uploadType: "ENCRYPT",
     inFolder: false,
     account,
     onUploadProgress: (progressEvent, name) => {},
   });
 };

```

Response of example:

```javascript
"data": {
        "id": "246203",
        "name": "images (3).jpeg",
        "url": "https://node1-gateway-ipfs.eueno.io/ipfs/Qmf7g...TYaLoA6pbJ3",
