Parameters: This method accepts single parameter options which is an optional parameter that holds the zlib options. 

Return Value: It returns a new BrotliDecompress object. 

The below examples illustrate the use of zlib.createBrotliDecompress() method in Node.js:

Example 1:

javascript

// Node.js program to demonstrate the
// createBrotliDecompress() method

// Including zlib module
const zlib = require('zlib');

// Calling brotliCompress function to compress data
zlib.brotliCompress('Nidhi', function (err, data) {
    if (err) {
        return console.log('err', err);
    }

    // Calling createBrotliDecompress method
    // to decompress the data again
    let gunzip = zlib.createBrotliDecompress();
    gunzip.write(data);
    gunzip.on('data', function (data) {
        console.log(data.toString());
    });
});

Output:

Nidhi

Example 2:

javascript

// Node.js program to demonstrate the
// createBrotliDecompress() method

// Including zlib module
const zlib = require('zlib');

// Calling brotliCompress function to compress data
zlib.brotliCompress('CS-Portal!', function (err, data) {
    if (err) {
        return console.log('err', err);
    }

    // Calling createBrotliDecompress method
    // to decompress the data again
    let gunzip = zlib.createBrotliDecompress();
    gunzip.write(data);
    gunzip.on('data', function (data) {
        console.log(data.toString('base64'));
    });
});
