Node.js zlib.brotliDecompressSync() Method Last Updated : 28 Apr, 2025 Suggest changes Share Like Article Like Report The zlib.brotliDecompressSync() method is an inbuilt application programming interface of the Zlib module which is used to decompress a chunk of data with BrotliDecompress. Syntax: zlib.brotliDecompressSync( 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 BrotliDecompress. The below examples illustrate the use of zlib.brotliDecompressSync() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // zlib.brotliDecompressSync() method // Including zlib module const zlib = require('zlib'); // Declaring input and assigning // it a value string let input = "Nidhi"; // Calling brotliDecompressSync method let brotliCom = zlib.brotliCompressSync(input); let brotliDec = zlib.brotliDecompressSync( new Buffer.from(brotliCom)).toString('hex'); console.log(brotliDec); Output: 4e69646869 Example 2: javascript // Node.js program to demonstrate the // zlib.brotliDecompressSync() method // Including zlib module const zlib = require('zlib'); // Declaring input and assigning // it a value string let input = "Nidhi"; // Calling brotliDecompressSync method let brotliCom = zlib.brotliCompressSync(input).toString('hex') let brotliDec = zlib.brotliDecompressSync( new Buffer.from(brotliCom, 'hex')).toString('base64'); console.log(brotliDec); Output: TmlkaGk= Reference: https://nodejs.org/api/zlib.html#zlib_zlib_brotlidecompresssync_buffer_options N nidhi1352singh Follow 0 Article Tags : Web Technologies Node.js Node.js-Zlib-module Explore Node.js Tutorial 3 min read Introduction & Installation NodeJS Introduction 3 min read Node.js Roadmap: A Complete Guide 6 min read How to Install Node.js on Linux 6 min read How to Install Node.js on Windows 5 min read How to Install NodeJS on MacOS 6 min read Node.js vs Browser - Top Differences That Every Developer Should Know 6 min read NodeJS REPL (READ, EVAL, PRINT, LOOP) 4 min read Explain V8 engine in Node.js 7 min read Node.js Web Application Architecture 3 min read NodeJS Event Loop 5 min read Node.js Modules , Buffer & StreamsNodeJS Modules 5 min read What are Buffers in Node.js ? 4 min read Node.js Streams 4 min read Node.js Asynchronous ProgrammingAsync Await in Node.js 3 min read Promises in NodeJS 7 min read How to Handle Errors in Node.js ? 4 min read Exception Handling in Node.js 3 min read Node.js NPMNodeJS NPM 6 min read Steps to Create and Publish NPM packages 7 min read Introduction to NPM scripts 2 min read Node.js package.json 4 min read What is package-lock.json ? 3 min read Node.js Deployments & CommunicationNode Debugging 2 min read How to Perform Testing in Node.js ? 2 min read Unit Testing of Node.js Application 5 min read NODE_ENV Variables and How to Use Them ? 2 min read Difference Between Development and Production in Node.js 3 min read Best Security Practices in Node.js 4 min read Deploying Node.js Applications 5 min read How to Build a Microservices Architecture with NodeJS 3 min read Node.js with WebAssembly 3 min read Resources & ToolsNode.js Web Server 6 min read Node Exercises, Practice Questions and Solutions 4 min read Node.js Projects 9 min read NodeJS Interview Questions and Answers 15+ min read My Profile ${profileImgHtml} My Profile Edit Profile My Courses Join Community Transactions Logout Like
