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, and string.
• options: This parameter holds the value of the zlib option.

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

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

Example 1:

javascript

// Node.js program to demonstrate the
// zlib.inflateSync() method

// Including zlib module
const zlib = require('zlib');

// Declaring input and assigning
// it a value string
const input = "GeeksforGeeks";

// Calling deflateSync method
const deflated = zlib.deflateSync(input);

// Calling inflateSync method
const inflated = zlib.inflateSync(
    new Buffer.from(deflated)).toString();

console.log(inflated);

Output:

GeeksforGeeks

Example 2:

javascript

// Node.js program to demonstrate the
// zlib.inflateSync() method

// Including zlib module
const zlib = require('zlib');

// Declaring input and assigning
// it a value string
const input = "GeeksforGeeks";

// Calling deflateSync method
const deflated = zlib.deflateSync(input).toString('hex');

// Calling inflateSync method
const inflated = zlib.inflateSync(new Buffer.from(
    deflated, 'hex')).toString('base64');

console.log(inflated);
