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
## Installation
Before running the code, make sure you have Node.js installed in your development environment. You can download it from the official Node.js website: [https://nodejs.org](https://nodejs.org)
To install the necessary dependencies, navigate to the project directory and run the following command:
```bash
npm install
```
This will install the required packages specified in the `package.json` file.
## Usage
### 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';
import IPFSFileUploader from './IPFSFileUploader.js';
class IPFSFileManager {
// ...
}
const ipfsUploader = new IPFSFileUploader();
const ipfsFileManager = new IPFSFileManager();
const filePath = './file.txt';
ipfsFileManager.addFileToIPFS(filePath);
const filePath = './file.txt'; // Replace with the path of the file you want to add to IPFS
ipfsUploader.uploadFileToIPFS(filePath);
```
Make sure to replace `filePath` with the path of the file you want to add to IPFS.
## Retrieving a File from 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';
import IPFSFileRetriever from './IPFSFileRetriever.js';
class IPFSFileManager {
// ...
}
const ipfsFileManager = new IPFSFileManager();
const ipfsRetriever = new IPFSFileRetriever();
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);
ipfsRetriever.retrieveFileFromIPFS(cid, filepath);
```
Make sure to replace `cid` with the CID of the file you want to retrieve from IPFS.
## Notes
- Make sure you have Node.js installed in your development environment.
- Install the necessary dependencies before running the code. You can use npm or yarn to install the dependencies specified in the `package.json` file.
- The code depends on the IPFS package for Node.js. It will be installed automatically when you run `npm install`.
- The code uses the `fs/promises` module for file operations, which is available in Node.js version 14.0.0 and above.
- Additional dependencies such as `file-type` may be required for file type determination. They will also be installed automatically.
Feel free to explore and modify the code according to your needs.
