Introduction to Kompression

Kompression is a powerful library that allows efficient data compression and decompression in various applications.
With an array of useful API methods, Kompression provides developers with the flexibility and performance needed for handling
large datasets, improving data storage efficiency, and optimizing data transmission. This guide will introduce you to Kompression
and provide dozens of API explanations with code snippets to help you get started.

Why Use Kompression?

Kompression is designed to be fast, efficient, and easy to use, making it an ideal solution for any application that requires
data compression. Whether you are developing web applications, data storage systems, or handling large files,
Kompression offers the tools you need.

Getting Started

The first step to using Kompression is installing the package:

npm install kompression

Basic API Usage

1. Compressing Data

const kompression = require('kompression');
const data = 'This is a string that we want to compress';
const compressedData = kompression.compress(data);
console.log(compressedData);

2. Decompressing Data

const decompressedData = kompression.decompress(compressedData);
console.log(decompressedData);

3. Compressing JSON

const jsonData = { key: 'value', anotherKey: 'another value' };
const compressedJson = kompression.compress(JSON.stringify(jsonData));
console.log(compressedJson);

4. Decompressing JSON

const decompressedJson = JSON.parse(kompression.decompress(compressedJson));
console.log(decompressedJson);

5. Compressing Files

const fs = require('fs');
const fileContent = fs.readFileSync('path/to/file.txt', 'utf8');
const compressedFileContent = kompression.compress(fileContent);
fs.writeFileSync('path/to/compressed-file.txt', compressedFileContent);

6. Decompressing Files

const compressedFileContent = fs.readFileSync('path/to/compressed-file.txt', 'utf8');
const decompressedFileContent = kompression.decompress(compressedFileContent);
fs.writeFileSync('path/to/decompressed-file.txt', decompressedFileContent);

Advanced API Usage

7. Setting Compression Levels

const compressedDataWithLevel = kompression.compress(data, { level: 6 });
console.log(compressedDataWithLevel);

8. Using Custom Compression Strategy

const customStrategy = new kompression.Strategy({
  compress: (input) => {
    // Custom compression logic
    return input.split('').reverse().join('');
  },
  decompress: (input) => {
    // Custom decompression logic
    return input.split('').reverse().join('');
  }
});

const customCompressed = customStrategy.compress(data);
const customDecompressed = customStrategy.decompress(customCompressed);
console.log(customCompressed);
console.log(customDecompressed);

Application Example

Below is an example of a simple Node.js application that uses the Kompression library.

const express = require('express');
const kompression = require('kompression');

const app = express();

app.use((req, res, next) => {
  const originalSend = res.send;
  res.send = function(data) {
    const compressedData = kompression.compress(data);
    res.set('Content-Encoding', 'kompressed');
    originalSend.call(res, compressedData);
  };
  next();
});

app.get('/', (req, res) => {
  res.send('Hello, this is compressed!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Conclusion

Mastering the use of Kompression can significantly enhance the performance and efficiency of your applications. From basic data
compression and decompression to advanced custom strategies, Kompression is a powerful tool for developers. Explore its APIs,
implement them in your projects, and experience the difference it makes.
