Node.js zlib.deflateRawSync() Method

The zlib.deflateRawSync() method is an inbuilt application programming interface of the Zlib module which is used to compress a chunk of data with DeflateRaw. 

Syntax:

zlib.deflateRawSync( buffer, options )

Parameters: This method accepts two parameters as mentioned above and described below:

• buffer: This parameter holds the buffer of type Buffer, TypedArray, DataView, ArrayBuffer, and string.
• options: This parameter holds the value of the zlib option.

Return Value: It returns the chunk of data with DeflateRaw.

 The below examples illustrate the use of zlib.deflateRawSync() method in Node.js:

Example 1:

javascript

// Node.js program to demonstrate the
// zlib.deflateRawSync() method

// Including zlib module
const zlib = require('zlib');

// Declaring input and assigning
// it a value string
const input = "GeeksforGeeks";

// Calling deflateRawSync method
const deflatedRS = zlib.deflateRawSync(input);

console.log(deflatedRS);

Output:

<Buffer 73 4f 4d cd 2e 4e cb 2f 72 07 d1 00>

Example 2:

javascript

// Node.js program to demonstrate the
// zlib.deflateRawSync() method

// Including zlib module
const zlib = require('zlib');

// Declaring input and assigning
// it a value string
const input = "GeeksforGeeks";

// Calling deflateRawSync method
const deflatedRS = zlib.deflateRawSync(input).toString('ascii');

console.log(deflatedRS);

Output:
