Installation

NPM

npm install @onurege3467/zero-compress

Yarn

yarn add @onurege3467/zero-compress

PNPM

pnpm add @onurege3467/zero-compress

Requirements

• Node.js: >= 16.0.0

Quick Start

Drop-in Replacement

Replace require('zlib') with @onurege3467/zero-compress:

// Before
const zlib = require('zlib');
zlib.gzip(data, callback);

// After - just change the import!
const zlib = require('@onurege3467/zero-compress');
zlib.gzip(data, callback);

Modern Async API

const { gzipAsync, gunzipAsync } = require('@onurege3467/zero-compress');

async function compressData() {
  const data = Buffer.from('Hello World!');
  const compressed = await gzipAsync(data);
  const decompressed = await gunzipAsync(compressed);

  console.log(decompressed.toString()); // 'Hello World!'
}

File Operations

const { compressFile, decompressFile } = require('@onurege3467/zero-compress');

async function handleFiles() {
  // Compress with detailed results
  const result = await compressFile('input.txt', 'output.gz');
  console.log(`Compressed: ${result.originalSize} → ${result.compressedSize} bytes`);
  console.log(`Ratio: ${(result.ratio * 100).toFixed(1)}%, Time: ${result.time}ms`);

  // Decompress
  await decompressFile('output.gz', 'restored.txt');
}

Basic Compression/Decompression

const { gzipAsync, gunzipAsync } = require('@onurege3467/zero-compress');

async function basicExample() {
  const originalData = Buffer.from('Hello, World! This is test data.');

  // Compress

File Compression with Progress

const { compressFile } = require('@onurege3467/zero-compress');
const fs = require('fs');

async function compressLargeFile() {
  const inputPath = 'large-file.txt';
  const stats = fs.statSync(inputPath);

  console.log(`Compressing ${stats.size} bytes...`);

  const result = await compressFile(inputPath, undefined, { level: 6 });

  console.log(`✅ Compression complete!`);
  console.log(`📊 Results:`);
  console.log(`   Original: ${result.originalSize} bytes`);
  console.log(`   Compressed: ${result.compressedSize} bytes`);
  console.log(`   Ratio: ${(result.ratio * 100).toFixed(1)}%`);
  console.log(`   Savings: ${result.savings.toFixed(1)}%`);
  console.log(`   Time: ${result.time}ms`);
}

Stream Processing

const { createEnhancedGzip } = require('@onurege3467/zero-compress');
const fs = require('fs');

function streamCompression() {
  const input = fs.createReadStream('input.txt');
  const output = fs.createWriteStream('output.txt.gz');
  const gzip = createEnhancedGzip({ level: 6 });

  input.pipe(gzip).pipe(output);

  gzip.on('error', (err) => {
    console.error('Compression error:', err);
  });

  output.on('finish', () => {
    console.log('Stream compression completed');
  });
}

HTTP Server Integration

const express = require('express');
const { gzipAsync } = require('@onurege3467/zero-compress');

const app = express();

app.get('/api/data', async (req, res) => {
  const data = { message: 'Hello World', timestamp: Date.now() };
  const jsonString = JSON.stringify(data);
  const compressed = await gzipAsync(Buffer.from(jsonString));

  res.set({
    'Content-Type': 'application/json',
    'Content-Encoding': 'gzip',
    'Content-Length': compressed.length
  });

  res.send(compressed);
});

app.listen(3000);

Error Handling

const { gzipAsync, gunzipAsync } = require('@onurege3467/zero-compress');

async function safeCompression() {
  try {
    const data = Buffer.from('Test data');
    const compressed = await gzipAsync(data);

    // Simulate corrupted data
    compressed[10] = 0xFF;
    compressed[11] = 0xFF;

    const decompressed = await gunzipAsync(compressed);
  } catch (error) {
    if (error.code === 'Z_DATA_ERROR') {
      console.log('Corrupted data detected');
    } else {
      console.error('Unexpected error:', error);
    }
  }
}

Configurable Security Limits

You can customize security limits via environment variables:

# Set max file size to 50MB (default: 100MB)
export ZERO_COMPRESS_MAX_FILE_SIZE=52428800

# Set max decompressed size to 100MB (default: 200MB)
export ZERO_COMPRESS_MAX_DECOMPRESSED_SIZE=104857600

# Set max memory usage to 250MB (default: 500MB)
export ZERO_COMPRESS_MAX_MEMORY_USAGE=262144000

// Or use programmatically
process.env.ZERO_COMPRESS_MAX_FILE_SIZE = '52428800';

Security Best Practices

// Always validate input
const { validateInput } = require('@onurege3467/zero-compress');

function secureCompress(data) {
  const safeData = validateInput(data);
  return gzipAsync(safeData, { level: 6 });
}

Troubleshooting

Common Issues

"Rate limit exceeded"

Solution: Wait before making more compression requests, or increase the rate limit.

"Input too large"

Solution: Files larger than 100MB are not supported for security reasons.

"Path traversal detected"

Solution: Avoid using .. in file paths or absolute paths outside the working directory.

"Module not found"

Solution: Ensure the package is properly installed:

npm install @onurege3467/zero-compress

"TypeScript errors"

Solution: Update TypeScript to version 4.5+ and ensure proper type imports.

Performance Tuning

For Maximum Speed

const options = { level: 1 }; // Fastest compression

For Best Compression

const options = { level: 9, memLevel: 9 }; // Best compression

For Memory Efficiency

const options = { level: 6, memLevel: 8, windowBits: 15 };
