Node.js zlib.unzipSync() Method
The zlib.unzipSync() method is an inbuilt application programming interface of the Zlib module which is used to decompress a chunk of data with Unzip.
Syntax:
zlib.unzipSync( buffer, options )
Parameters: This method accepts two parameters as mentioned above and described below:
- buffer: It can be of type Buffer, TypedArray, DataView, ArrayBuffer, and string.
- options: It is an optional parameter that holds the zlib options.
Return Value: It returns the chunk of data with Unzip.
Below examples illustrate the use of zlib.unzipSync() method in Node.js:
Example 1:
// Node.js program to demonstrate the // zlib.unzipSync() method // Including zlib module var zlib = require( 'zlib' ); // Declaring input and assigning // it a value string var input = "NidhiSingh" ; // Calling gzipSync method var gzi = zlib.gzipSync(input); // Calling unzipSync method var decom = zlib.unzipSync( new Buffer.from(gzi)).toString( 'base64' ); console.log(decom); |
Output:

Example 2:
// Node.js program to demonstrate the // zlib.unzipSync() method // Including zlib module var zlib = require( 'zlib' ); // Declaring input and assigning // it a value string var input = "NidhiSingh" ; // Calling gzipSync method var gzi = zlib.gzipSync(input).toString( 'hex' ); // Calling unzipSync method var decom = zlib.unzipSync( new Buffer.from(gzi, 'hex' )).toString( 'hex' ); console.log(decom); |
