# IPFS File Manager
|
|
|
|
This repository contains JavaScript code to interact with IPFS (InterPlanetary File System). It provides functionalities to add and retrieve files from IPFS.
|
|
|
|
## Adding a File to IPFS
|
|
|
|
To add a file to IPFS, use the following code:
|
|
|
|
```javascript
|
|
import { create } from 'ipfs';
|
|
import { writeFile } from 'fs/promises';
|
|
|
|
class IPFSFileManager {
|
|
// ...
|
|
}
|
|
|
|
const ipfsFileManager = new IPFSFileManager();
|
|
|
|
const filePath = './file.txt';
|
|
ipfsFileManager.addFileToIPFS(filePath);
|
|
```
|
|
|
|
Make sure to replace `filePath` with the path of the file you want to add to IPFS.
|
|
|
|
## Retrieving a File from IPFS
|
|
|
|
To retrieve a file from IPFS, use the following code:
|
|
|
|
```javascript
|
|
import { create } from 'ipfs';
|
|
import { writeFile } from 'fs/promises';
|
|
import { fileTypeFromBuffer } from 'file-type';
|
|
|
|
class IPFSFileManager {
|
|
// ...
|
|
}
|
|
|
|
const ipfsFileManager = new IPFSFileManager();
|
|
|
|
const cid = 'QmQgGxzWnzjCfouxRiozBiEG3wcsuJGWjtHjv3wurVbJ9s'; // Replace with the CID of the file you want to retrieve
|
|
const filepath = './retrievedFile'; // Specify the file path without the extension
|
|
ipfsFileManager.retrieveFileFromIPFS(cid, filepath);
|
|
```
|
|
|
|
Make sure to replace `cid` with the CID of the file you want to retrieve from IPFS.
|
|
|
|
