  • Last Updated : 05 Mar, 2020

The zlib.createInflateRaw() method is an inbuilt application programming interface of the Zlib module which is used to create a new InflateRaw object.

Syntax:

zlib.createInflateRaw( options )

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

Return Value: It returns a new InflateRaw object.

Below examples illustrate the use of zlib.createInflateRaw() method in Node.js:



Example 1:




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

Output:

Decompressed..

Example 2:




// Node.js program to demonstrate the     
// createInflateRaw() method
  
// Including zlib module
var zlib = require('zlib');
  
// Calling deflateRaw function to compress data
zlib.deflateRaw('Decompressed..', function(err, data)
 {
  if (err) 
  
    return console.log('err', err);
  }
  
  // Calling createInflateRaw method
  // to decompress the data again
  var gunzip = zlib.createInflateRaw();
  gunzip.write(data);
  gunzip.on('data', function (data)
   {
      console.log(data.toString('base64'));
  });
});
