Node.js zlib.gunzipSync() Method
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, and string.
- options: This parameter holds the value of the zlib option.
Return Value: It returns the chunk of data with Gunzip.
The below examples illustrate the use of zlib.gunzipSync() method in Node.js:
Example 1:
javascript
// Node.js program to demonstrate the // zlib.gunzipSync() method // Including zlib module const zlib = require( 'zlib' ); // Declaring input and assigning // it a value string const input = "Nidhi" ; // Calling gzipSync method const gzi = zlib.gzipSync(input); // Calling gunzipSync method const decom = zlib.gunzipSync( new Buffer.from(gzi)).toString(); console.log(decom); |
Output:
Nidhi
Example 2:
javascript
// Node.js program to demonstrate the // zlib.gunzipSync() method // Including zlib module const zlib = require( 'zlib' ); // Declaring input and assigning // it a value string const input = "Nidhi" ; // Calling gzipSync method const gzi = zlib.gzipSync(input).toString( 'hex' ); // Calling gunzipSync method const decom = zlib.gunzipSync( new Buffer.from( gzi, 'hex' )).toString( 'base64' ); console.log(decom); |
