Introduction to ftp-deploy

In the rapidly evolving world of web development, automation is key. Ftp-deploy is a powerful, yet simple tool to help automate your deployment process. Whether you’re pushing changes to a static site or a complex web application, ftp-deploy streamlines the upload of files to your FTP server, making your workflow more efficient and error-free.

Getting Started with ftp-deploy

To start using ftp-deploy, you need to have Node.js and npm installed on your machine. You can install ftp-deploy globally using the following command:

  npm install -g ftp-deploy

Basic Usage

Once installed, you can use ftp-deploy in your project by creating a deployment script. Below is a basic example of how to use ftp-deploy:

  const FtpDeploy = require('ftp-deploy');
  const ftpDeploy = new FtpDeploy();
  
  const config = {
    user: "username",
    password: "password",
    host: "ftp.yoursite.com",
    port: 21,
    localRoot: __dirname + "/local-folder",
    remoteRoot: "/remote-folder/",
    include: ['*', '**/*'],      // This will upload everything in the local folder
    deleteRemote: false,         // This option doesn't remove files on the server not present in local folder
    forcePasv: true
  };
  
  ftpDeploy.deploy(config, function(err, res) {
    if (err) console.log(err);
    else console.log('Deployment successful:', res);
  });

Advanced Configuration

For more advanced scenarios, ftp-deploy allows customization to fit your specific needs:

Including Specific Files

  include: ['index.html', 'css/**', 'js/app.js']

Excluding Files

  exclude: ['node_modules/**', 'tests/**']

Deleting Remote Files

You can enable the deletion of remote files that are not in the local directory:

  deleteRemote: true

Error Handling

ftp-deploy provides excellent error handling capabilities. Here is an example of how to catch and handle errors:

  ftpDeploy.deploy(config)
    .then(res => console.log('Deployment finished:', res))
    .catch(err => console.log('Deployment failed:', err));

Event Listeners

To track progress, you can attach listeners to various events like upload, error, and log:

  ftpDeploy.on('uploading', function(data) {
    console.log('Uploading', data.filename); 
  });
  
  ftpDeploy.on('uploaded', function(data) {
    console.log('Uploaded', data.filename);
  });
  
  ftpDeploy.on('log', function(data) {
    console.log('Log', data);
  });
  
  ftpDeploy.on('error', function(data) {
    console.log('Error', data.err);
  });

Application Example

Here’s a small example app that demonstrates using ftp-deploy to automate deployment of a static website:

  const express = require('express');
  const app = express();
  const path = require('path');

  app.use(express.static(path.join(__dirname, 'public')));

  app.get('/', (req, res) => {
    res.sendFile(path.join(__dirname, 'public', 'index.html'));
  });

  const PORT = process.env.PORT || 3000;
  app.listen(PORT, () => console.log(`Server running on port ${PORT}`));

  const FtpDeploy = require('ftp-deploy');
  const ftpDeploy = new FtpDeploy();

  const deployConfig = {
    user: "username",
    password: "password",
    host: "ftp.yoursite.com",
    port: 21,
    localRoot: __dirname + "/public",
    remoteRoot: "/remote-folder/",
    include: ['*', '**/*'],
    deleteRemote: false,
    forcePasv: true
  };

  ftpDeploy.deploy(deployConfig, function(err, res) {
    if (err) console.log(err);
    else console.log('Deployment successful:', res);
  });

With this setup, you can run your application locally and deploy it to your FTP server with ease.

Conclusion

Ftp-deploy is a versatile tool for automating the deployment of files to an FTP server. Whether you’re deploying a simple static website or a more complex application, ftp-deploy simplifies the process, reducing the chance of errors and saving you time. Try it out in your next project and experience the efficiency!
