Introduction to Kompression

Kompression is an advanced and efficient tool for data compression in web applications. Its intuitive API allows developers to compress and decompress data seamlessly, enhancing performance and reducing bandwidth usage. In this blog post, we will explore numerous useful APIs provided by Kompression with practical examples.

Dozens of Useful Kompression API Explanations

Basic Compression

To get started with Kompression, let’s look at a basic example of compressing a string.

  const kompression = require('kompression');
  const data = 'Hello, World!';
  const compressedData = kompression.compress(data);
  console.log(compressedData);

Basic Decompression

Once data is compressed, it can be easily decompressed using the API.

  const decompressedData = kompression.decompress(compressedData);
  console.log(decompressedData); // Output: 'Hello, World!'

Advanced Compression with Options

Kompression allows you to specify options for advanced compression techniques:

  const options = {
    level: 9,
    strategy: 'huffman'
  };
  const advancedCompressedData = kompression.compress(data, options);
  console.log(advancedCompressedData);

Stream Compression

For large datasets, stream compression can be utilized to handle the data efficiently:

  const fs = require('fs');
  const input = fs.createReadStream('input.txt');
  const output = fs.createWriteStream('output.kompressed');

  input.pipe(kompression.createCompressStream()).pipe(output);

Stream Decompression

Similarly, large datasets can be decompressed using a stream:

  const decompressedOutput = fs.createWriteStream('decompressed.txt');

  fs.createReadStream('output.kompressed')
    .pipe(kompression.createDecompressStream())
    .pipe(decompressedOutput);

Compressing Buffers

Kompression handles various types of data, including Buffer objects:

  const buffer = Buffer.from('This is some data');
  const compressedBuffer = kompression.compress(buffer);
  console.log(compressedBuffer);

Decompressing Buffers

Decompression of buffers is just as simple:

  const decompressedBuffer = kompression.decompress(compressedBuffer);
  console.log(decompressedBuffer.toString()); // Output: 'This is some data'

Example App Using Kompression APIs

To demonstrate the power and flexibility of Kompression, let’s build a simple command-line application that compresses and decompresses files.

  // app.js
  const fs = require('fs');
  const path = require('path');
  const kompression = require('kompression');

  const action = process.argv[2];
  const inputPath = process.argv[3];
  const outputPath = process.argv[4];

  if (action === 'compress') {
    const input = fs.createReadStream(inputPath);
    const output = fs.createWriteStream(outputPath);
    input.pipe(kompression.createCompressStream()).pipe(output);
  } else if (action === 'decompress') {
    const input = fs.createReadStream(inputPath);
    const output = fs.createWriteStream(outputPath);
    input.pipe(kompression.createDecompressStream()).pipe(output);
  } else {
    console.log('Unknown action. Use "compress" or "decompress".');
  }

To use this app, run the following commands:

  node app.js compress input.txt output.kompressed
  node app.js decompress output.kompressed decompressed.txt

With these simple APIs, you can integrate powerful compression features into your applications seamlessly.
