Node.js zlib.deflateRawSync() Method
The zlib.deflateRawSync() method is an inbuilt application programming interface of the Zlib module which is used to compress a chunk of data with DeflateRaw.
Syntax:
zlib.deflateRawSync( 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 DeflateRaw.
The below examples illustrate the use of zlib.deflateRawSync() method in Node.js:
Example 1:
javascript
// Node.js program to demonstrate the // zlib.deflateRawSync() method // Including zlib module const zlib = require( 'zlib' ); // Declaring input and assigning // it a value string const input = "w3wiki" ; // Calling deflateRawSync method const deflatedRS = zlib.deflateRawSync(input); console.log(deflatedRS); |
Output:
<Buffer 73 4f 4d cd 2e 4e cb 2f 72 07 d1 00>
Example 2:
javascript
// Node.js program to demonstrate the // zlib.deflateRawSync() method // Including zlib module const zlib = require( 'zlib' ); // Declaring input and assigning // it a value string const input = "w3wiki" ; // Calling deflateRawSync method const deflatedRS = zlib.deflateRawSync(input).toString( 'ascii' ); console.log(deflatedRS); |
Output:
