How to use the deflateRaw function from pako

In JavaScript, pako.deflateRaw is a method provided by the Pako library that compresses a raw data buffer using the DEFLATE algorithm.

How does pako.deflateRaw work?

In JavaScript, pako.deflateRaw is a method provided by the Pako library that compresses a raw data buffer using the DEFLATE algorithm. The DEFLATE algorithm is a lossless compression algorithm that is widely used in various applications, including ZIP files, PNG images, and HTTP compression. It works by replacing repeated patterns in the data with shorter codes, reducing the size of the data without losing any information. The deflateRaw method in Pako takes a raw data buffer as input and compresses it using the DEFLATE algorithm. The compressed data is returned as a new buffer. The method supports various options that can be used to customize the compression process, such as: level: the compression level, ranging from 0 (no compression) to 9 (maximum compression). windowBits: the size of the compression window, which affects the memory usage and compression ratio. memLevel: the amount of memory to be used by the compression algorithm. By default, deflateRaw uses the fastest compression level (level: 2) and a default compression window size (windowBits: 15). Overall, pako.deflateRaw provides a simple and efficient way to compress raw data using the DEFLATE algorithm in JavaScript, making it easier to optimize data transfer and storage in various applications.

const pako = require("pako");

// Create a new raw data buffer
const rawData = new Uint8Array([
  0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x2c, 0x20, 0x77, 0x6f, 0x72, 0x6c, 0x64,
]);

// Compress the raw data buffer using pako.deflateRaw()
const compressedData = pako.deflateRaw(rawData);

console.log(compressedData);

In this example, we import the Pako library and create a new raw data buffer using the Uint8Array constructor. The raw data buffer contains the ASCII-encoded string "Hello, world". We then use the pako.deflateRaw() method to compress the raw data buffer using the DEFLATE algorithm. The resulting compressed data is stored in the compressedData buffer. Finally, we log the compressed data buffer to the console using console.log(). When the code is executed, the output will be a new Uint8Array buffer containing the compressed data: css Copy code
