Compression using gzip

This code demonstrates how to compress a file using gzip. It reads from 'input.txt' and writes the compressed data to 'input.txt.gz'.

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

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

input.pipe(zlib.createGzip()).pipe(output);

Decompression using gzip

This code demonstrates how to decompress a gzip file. It reads from 'input.txt.gz' and writes the decompressed data to 'input.txt'.

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

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

input.pipe(zlib.createGunzip()).pipe(output);

Compression using deflate

This code demonstrates how to compress a file using deflate. It reads from 'input.txt' and writes the compressed data to 'input.txt.deflate'.

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

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

input.pipe(zlib.createDeflate()).pipe(output);

Decompression using deflate

This code demonstrates how to decompress a deflate file. It reads from 'input.txt.deflate' and writes the decompressed data to 'input.txt'.

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

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

input.pipe(zlib.createInflate()).pipe(output);
