Return value
The createGunzip() method returns a new Gunzip object.
Example
In the following example, we first compress the data in line 4 using the gzip method. Then, we create the gunzip object using the createGunzip() method (line 10) to decompress the data.
var zlib = require('zlib');
// First we compress the data
zlib.gzip('Educative', (err, buffer) => {
if (err) {
return console.log('err', err);
}
// Calling createGunzip method to decompress the data again
var gunzip = zlib.createGunzip();
gunzip.write(buffer);
gunzip.on('data', (buffer) =>
{
console.log(buffer.toString());
});
});
