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); |
