Node.js zlib.brotliCompress() Method
The zlib.brotliCompress() method is an inbuilt application programming interface of the Zlib module which is used to compresses a chunk of data.
Syntax:
zlib.brotliCompress( buffer, options, callback )
Parameters: This method accepts three 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.
- callback: It holds the callback function.
Return Value: It returns the chunk of data after compression.
Below examples illustrate the use of zlib.brotliCompress() method in Node.js:
Example 1:
// Node.js program to demonstrate the // brotliCompress() method // Including zlib module const zlib = require( "zlib" ); // Declaring input and assigning // it a value string var input = "Computer Science" ; // Calling brotliCompress method zlib.brotliCompress(input, (err, buffer) => { console.log(buffer.toString( 'base64' )); }); |

Example 2:
// Node.js program to demonstrate the // brotliCompress() method // Including zlib module const zlib = require( "zlib" ); // Declaring input and assigning // it a value string var input = "Computer Science" ; // Calling brotliCompress method zlib.brotliCompress(input, (err, buffer) => { if (!err) { console.log(buffer.toString( 'hex' )); } else { console.log(err); } }); |
