The zlib
module in Node.js provides compression and decompression functionality utilizing Gzip, Deflate/Inflate, and Brotli.
It can be accessed in your program with:
const zlib = require('zlib');
gzipSync()
is a function of the zlib
module, which allows compressing a chunk of data.
zlib.gzipSync( buffer, options )
buffer
is the data to be compressed. It can be of any type, such as Buffer
, TypedArray
, DataView
, ArrayBuffer
, or string
.
options
is used to provide options to the zlib
classes.
The gzipSync()
method returns compressed data.
In the following example, we provide an input string to the gzipSync()
method, which compresses the input in line 8.
// Including zlib moduleconst zlib = require("zlib");//input declarationvar input = "Educative";// Calling gzip method to compress datavar compressed = zlib.gzipSync(input);console.log("Compressed data: ",compressed.toString('utf8'));
