Introduction to Kompression

Kompression is a powerful file compression library that simplifies how developers handle file compression and decompression tasks. This guide covers an in-depth explanation of various kompression APIs along with helpful code snippets to enhance your learning and implementation.

Using Kompression APIs

Below are examples of some of the most essential kompression APIs:

1. Compressing a File

Use the compress method to compress a single file.

  let compressor = new Kompression();
  compressor.compress('example.txt', 'example.txt.gz');

2. Decompressing a File

Use the decompress method to decompress a file.

  let decompressor = new Kompression();
  decompressor.decompress('example.txt.gz', 'example.txt');

3. Compressing a Directory

Compress an entire directory using the compressDirectory method.

  let directoryCompressor = new Kompression();
  directoryCompressor.compressDirectory('exampleDir', 'exampleDir.zip');

4. Decompressing a Directory

Decompress a directory using the decompressDirectory method.

  let directoryDecompressor = new Kompression();
  directoryDecompressor.decompressDirectory('exampleDir.zip', 'exampleDir');

5. Listing Contents of a Compressed File

Use the listContents method to list the contents of a compressed file.

  let contentLister = new Kompression();
  let contents = contentLister.listContents('example.zip');
  console.log(contents);

Application Example

Here’s a practical application example utilizing multiple kompression APIs:

  const Kompression = require('kompression');

  function compressFilesInDirectory(directory) {
    let compressor = new Kompression();
    compressor.compressDirectory(directory, directory + '.zip');
    console.log('Directory compressed successfully.');
  }

  function decompressFilesInDirectory(zipFileName) {
    let decompressor = new Kompression();
    decompressor.decompressDirectory(zipFileName, zipFileName.replace('.zip', ''));
    console.log('Directory decompressed successfully.');
  }

  function listCompressedFileContents(zipFileName) {
    let lister = new Kompression();
    let contents = lister.listContents(zipFileName);
    console.log('Contents of the compressed file:');
    console.log(contents);
  }

  // Example usage
  compressFilesInDirectory('testDir');
  decompressFilesInDirectory('testDir.zip');
  listCompressedFileContents('testDir.zip');

By following this guide and utilizing the provided examples, you can enhance your file compression tasks with the kompression library.
