Node.js zlib.brotliCompressSync() Method

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

Syntax:

zlib.brotliCompressSync( 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: It is an optional parameter.

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

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

Example 1:

javascript

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

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

// Declaring input and assigning
// it a value string
let input = "0123456789";

// Calling brotliCompressSync method
const brotliCom = zlib.brotliCompressSync(input);

console.log(brotliCom);

Output:

// Buffer 8b 04 80 30 31 32 33 34 35 36 37 38 39 03

Example 2:

javascript

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

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

// Declaring input and assigning
// it a value string
let input = "0123456789";

// Calling brotliCompressSync method
const brotliCom = zlib.brotliCompressSync(input).toString('hex');

console.log(brotliCom);

Output:
