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

Example 1:

javascript

// Node.js program to demonstrate the     
// createInflate() method
 
// Including zlib module
const zlib = require('zlib');
 
// Calling deflate function to compress data
zlib.deflate('Hello World!', function (err, data) {
    if (err) {
        return console.log('err', err);
    }
 
    // Calling createInflate method
    // to decompress the data again
    const gunzip = zlib.createInflate();
    gunzip.write(data);
    gunzip.on('data', function (data) {
        console.log(data.toString());
    });
});

Output:

Hello World!

Example 2:

javascript

// Node.js program to demonstrate the     
// createInflate() method
 
// Including zlib module
const zlib = require('zlib');
 
// Calling deflate function to compress data
zlib.deflate('Decompressed..', function (err, data) {
    if (err) {
        return console.log('err', err);
    }
 
    // Calling createInflate method
    // to decompress the data again
    const gunzip = zlib.createInflate();
    gunzip.write(data);
    gunzip.on('data', function (data) {
        console.log(data.toString('hex'));
    });
});
