Introduction to Zip-Folder API

The Zip-Folder API is a powerful tool that allows developers to easily compress and decompress folders. This API is frequently used in web applications to handle data storage and transmission efficiently. In this article, we will explore dozens of useful API functionalities with code snippets and demonstrate an example app that utilizes these APIs. Let’s dive in!

Getting Started

First, ensure you have the zip-folder library installed in your project. You can install it using npm:

  npm install zip-folder

Basic Usage

The following example demonstrates how to zip a folder:

  
  const zipFolder = require('zip-folder');

  zipFolder('path/to/source/folder', 'path/to/destination.zip', function(err) {
    if (err) {
      console.log('Error zipping folder', err);
    } else {
      console.log('Folder successfully zipped');
    }
  });
  

Error Handling

Proper error handling is vital in any application. Here’s an example of how you can handle errors effectively:

  
  const zipFolder = require('zip-folder');

  function zipDirectory(source, out) {
    return new Promise((resolve, reject) => {
      zipFolder(source, out, function(err) {
        if (err) {
          reject(err);
        } else {
          resolve();
        }
      });
    });
  }

  zipDirectory('path/to/source/folder', 'path/to/destination.zip')
    .then(() => {
      console.log('Directory successfully zipped');
    })
    .catch(err => {
      console.error('Error zipping folder', err);
    });
  

Unzipping a Folder

Unzipping can be performed using the unzipper library:

  
  const unzipper = require('unzipper');
  const fs = require('fs');

  fs.createReadStream('path/to/source.zip')
    .pipe(unzipper.Extract({ path: 'path/to/destination/folder' }))
    .on('close', () => console.log('Extraction complete.'));
  

Example Application

In this example, we will create a simple Node.js application that compresses and decompresses folders.

Project Structure

  
  my-zip-app/
  ├── node_modules/
  ├── src/
  │   ├── index.js
  ├── package.json
  

Source Code

index.js

  
  const zipFolder = require('zip-folder');
  const unzipper = require('unzipper');
  const fs = require('fs');

  const action = process.argv[2];
  const source = process.argv[3];
  const output = process.argv[4];

  if (action === 'zip') {
    zipFolder(source, output, function(err) {
      if (err) {
        console.log('Error zipping folder', err);
      } else {
        console.log('Folder successfully zipped');
      }
    });
  } else if (action === 'unzip') {
    fs.createReadStream(source)
      .pipe(unzipper.Extract({ path: output }))
      .on('close', () => console.log('Extraction complete.'));
  } else {
    console.log('Invalid action. Use "zip" or "unzip".');
  }
  

To zip a folder, run:

  node src/index.js zip path/to/source/folder path/to/destination.zip

To unzip a folder, run:

  node src/index.js unzip path/to/source.zip path/to/destination/folder

In this guide, we have covered the basic uses and functionalities of the zip-folder API. This versatile tool can simplify the process of managing compressed folders in your applications. Be sure to explore further and leverage its full potential in your projects!
