Javascript - Node.js copy remote file to server

To copy a remote file to a server using Node.js, you can utilize the http or https modules to make a request to the remote server, retrieve the file, and then use the fs module to write the file to your server. Additionally, you can use libraries like axios or node-fetch for easier handling of HTTP requests.

Here's a basic example using axios:

const axios = require('axios'); const fs = require('fs'); // Remote file URL const remoteFileUrl = 'http://example.com/path/to/remote/file.txt'; // Local file path where the file will be saved const localFilePath = '/path/to/local/file.txt'; // Function to download the file async function downloadFile() { try { const response = await axios.get(remoteFileUrl, { responseType: 'stream' }); const writer = fs.createWriteStream(localFilePath); response.data.pipe(writer); return new Promise((resolve, reject) => { writer.on('finish', resolve); writer.on('error', reject); }); } catch (error) { console.error('Error downloading file:', error); } } // Call the function downloadFile() .then(() => console.log('File downloaded successfully!')) .catch(error => console.error('Error:', error));

In this example:

  1. We import the axios library for making HTTP requests and the fs module for file system operations.
  2. Define the URL of the remote file and the local file path where you want to save the file.
  3. Create an asynchronous function downloadFile() to download the file. Inside this function:
    • We use axios.get() to make a GET request to the remote file URL with responseType: 'stream' to get a readable stream of the file.
    • We create a writable stream using fs.createWriteStream() to write the file locally.
    • We pipe the data from the response stream to the writable stream.
  4. Finally, we call the downloadFile() function and handle success and error cases using promises.

Remember to replace 'http://example.com/path/to/remote/file.txt' with the actual URL of the remote file and '/path/to/local/file.txt' with the desired local file path.
