Node.js stringDecoder.write() Method Last Updated : 08 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The stringDecoder.write() method is used to return a decoded string from the given Buffer, TypedArray or DataView. This method also ensures that any incomplete multibyte characters at the end of the buffer are omitted from the returned string. These characters are stored in an internal buffer for the next call to the stringDecoder.write() or stringDecoder.end() methods. Syntax: stringDecoder.write( buffer ) Parameters: This method accepts single parameter as mentioned above and described below: buffer: It is a Buffer, TypedArray or DataView that contains the bytes that have to be decoded. Return Value: It returns a string which is decoded from the given buffer. Below programs illustrate the stringDecoder.write() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // stringDecoder.write() Method // Import the string_decoder module // and get the StringDecoder class // using object destructuring const { StringDecoder } = require("string_decoder"); // Create a new instance of the decoder const decoder = new StringDecoder("utf-8"); const text_one = Buffer.from("GeeksforGeeks", "utf-8"); let decoded_text = decoder.write(text_one); console.log("Decoded Text:", decoded_text); Output: Decoded Text: GeeksforGeeks Example 2: javascript // Node.js program to demonstrate the // stringDecoder.write() Method // Import the string_decoder module // and get the StringDecoder class // using object destructuring const { StringDecoder } = require("string_decoder"); // Create a new instance of the decoder const decoder = new StringDecoder("utf-8"); // Decoding text using hex from buffer const hex_text = new Buffer.from( "4765656B73666F724765656B73", "hex"); let decoded_hex_text = decoder.write(hex_text); console.log("Decoded Text Hex:", decoded_hex_text); // Decoding text using base64 from buffer const base64_text = new Buffer.from( "R2Vla3Nmb3JHZWVrcw==", "base64"); let decoded_base64_text = decoder.write(base64_text); console.log("Decoded Text Base64:", decoded_base64_text); // Decoding the cent symbol from buffer const cent_symbol = Buffer.from([0xc2, 0xa2]); let cent_symbol_out = decoder.write(cent_symbol); console.log("Cent Symbol:", cent_symbol_out); Output: Decoded Text Hex: GeeksforGeeks Decoded Text Base64: GeeksforGeeks Cent Symbol: ¢ Reference: https://nodejs.org/api/string_decoder.html#string_decoder_stringdecoder_write_buffer Create Quiz Comment S sayantanm19 Follow 0 Improve S sayantanm19 Follow 0 Improve Article Tags : Web Technologies Node.js Node.js-Methods 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 Like
