Node.js | zlib.gunzipSync() Method

  • Last Updated : 13 Mar, 2020

The zlib.gunzipSync() method is an inbuilt application programming interface of the Zlib module which is used to decompress a chunk of data with Gunzip.

Syntax:

zlib.gunzipSync( 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, string.
  • options: This parameter holds the zlib options value.

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

Below examples illustrate the use of zlib.gunzipSync() method in Node.js:



Example 1:




// Node.js program to demonstrate the     
// zlib.gunzipSync() method  
  
// Including zlib module
var zlib = require('zlib');
  
// Declaring input and assigning
// it a value string
var input = "Nidhi";
  
// Calling gzipSync method
var gzi = zlib.gzipSync(input);
  
// Calling gunzipSync method
var decom = zlib.gunzipSync(
    new Buffer.from(gzi)).toString();
  
console.log(decom);

Output:

Nidhi

Example 2:




// Node.js program to demonstrate the     
// zlib.gunzipSync() method  
  
// Including zlib module
var zlib = require('zlib');
  
// Declaring input and assigning
// it a value string
var input = "Nidhi";
  
// Calling gzipSync method
var gzi = zlib.gzipSync(input).toString('hex');
  
// Calling gunzipSync method
var decom = zlib.gunzipSync(new Buffer.from(
        gzi, 'hex')).toString('base64');
  
console.log(decom);

Output:
