The zlib.inflateRaw() method is an inbuilt application programming interface of the Zlib module which is used to decompress a chunk of data.
Syntax:
zlib.inflateRaw( 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 decompression.
Below examples illustrate the use of zlib.inflateRaw() method in Node.js:
Example 1:
// Node.js program to demonstrate the // inflateRaw() method // Including zlib module const zlib = require( "zlib" );
// Declaring input and assigning // it a value string var input = "GeeksforGeeks" ;
// Calling deflateRaw method zlib.deflateRaw(input, (err, buffer) => { // Calling inflateRaw
zlib.inflateRaw(buffer, (err, buffer) => {
console.log(buffer.toString( 'utf8' ));
});
}); |
Output:
GeeksforGeeks
Example 2:
// Node.js program to demonstrate the // inflateRaw() method // Including zlib module const zlib = require( "zlib" );
// Declaring input and assigning // it a value string var input = "GeeksforGeeks" ;
// Calling deflateRaw method zlib.deflateRaw(input, (err, buffer) => { // Calling inflateRaw
zlib.inflateRaw(buffer, (err, buffer) => {
console.log(buffer.toString( 'base64' ));
});
}); |
