The following script demonstrates how to connect to a server and download a specific file to your local directory. javascript
This library simplifies the connection lifecycle and error handling. Step 1: Installation Install the package using your terminal: npm install basic-ftp Use code with caution. Step 2: Download Code Example
: The most modern choice. It uses a Promise-based API and supports explicit and implicit FTPS. download file from ftp server using node js
: For very large files, consider using streams to avoid high memory usage in your Node.js application. Using NodeJS and FTP with Promises
const ftp = require("basic-ftp") const fs = require("fs") async function downloadFile() { const client = new ftp.Client() // Optional: enable detailed logging for debugging client.ftp.verbose = true try { await client.access({ host: "ftp.example.com", user: "your-username", password: "your-password", secure: true // Uses FTPS (TLS) for security }) console.log("Connected successfully.") // downloadTo(localPath, remotePath) await client.downloadTo("local-folder/report.pdf", "remote-folder/report.pdf") console.log("Download complete!") } catch (err) { console.error("Error during FTP operation:", err) } finally { client.close() } } downloadFile() Use code with caution. 3. Handling SFTP (Secure Shell) The following script demonstrates how to connect to
: Essential if your "FTP" server is actually an SFTP (SSH File Transfer Protocol) server, which uses a completely different protocol.
Downloading files from an FTP server is a common task in Node.js for automating backups, synchronizing data, or processing remote reports. While several libraries exist, the modern standard is basic-ftp due to its native support for , async/await , and FTPS (TLS) . 1. Choosing the Right Library Step 2: Download Code Example : The most modern choice
If your server requires a secure SSH connection, use the ssh2-sftp-client library. javascript
: Wrap your logic in try...catch blocks to handle common network issues like connection timeouts or "file not found" errors.
const Client = require('ssh2-sftp-client'); const sftp = new Client(); async function downloadFromSFTP() { try { await sftp.connect({ host: 'sftp.example.com', port: '22', username: 'user', password: 'password' }); // You can also download entire directories with downloadDir() await sftp.fastGet('/remote/path/file.zip', './local/path/file.zip'); } finally { await sftp.end(); } } Use code with caution. 4.
