Node.js zlib.inflateSync() Method

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);
