Node.js | zlib.inflateSync() Method

  • Last Updated : 13 Mar, 2020

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

Syntax:

zlib.inflateSync( 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 Inflate.

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



Example 1:




// Node.js program to demonstrate the     
// zlib.inflateSync() method  
  
// Including zlib module
var zlib = require('zlib');
  
// Declaring input and assigning
// it a value string
var input = "GeeksforGeeks";
  
// Calling deflateSync method
var deflated = zlib.deflateSync(input);
  
// Calling inflateSync method
var inflated = zlib.inflateSync(
    new Buffer.from(deflated)).toString();
  
console.log(inflated);

Output:

GeeksforGeeks

Example 2:




// Node.js program to demonstrate the     
// zlib.inflateSync() method  
  
// Including zlib module
var zlib = require('zlib');
  
// Declaring input and assigning
// it a value string
var input = "GeeksforGeeks";
  
// Calling deflateSync method
var deflated = zlib.deflateSync(input).toString('hex');
  
// Calling inflateSync method
var inflated = zlib.inflateSync(new Buffer.from(
      deflated, 'hex')).toString('base64');
  
console.log(inflated);
