Node.js Brotli - JavaScript

Node.js Brotli is a module that allows developers to use the Brotli compression algorithm within their Node.js applications. This algorithm was developed by Google and is designed to provide better compression ratios than other popular algorithms like Gzip and Deflate.

Installing Node.js Brotli

To use Node.js Brotli in your projects, you must first install it using npm:

npm install brotli

Using Node.js Brotli

Using Brotli with Node.js is simple. First, you need to import the brotli module:

const brotli = require('brotli');

Once you have imported the module, you can use its functions to compress or decompress data:

// compress some data
const compressed = brotli.compress('Hello, World!');

// decompress the compressed data
const decompressed = brotli.decompress(compressed);

More Advanced Usage

You can also configure the compression level and input block size of Brotli by passing in options to the compress function:

// compress some data, using a higher compression level and larger input blocks
const compressed = brotli.compress('Hello, World!', {
  quality: 11,
  sizeHint: 4096
});

Additionally, Brotli supports streaming compression and decompression:

// create a Brotli compressor stream
const compressor = brotli.createCompress();

// create a Brotli decompressor stream
const decompressor = brotli.createDecompress();

// pipe some data through the compressor, then through the decompressor
const compressed = 'Hello, World!';
const compressedStream = compressor.pipe(decompressor);

// listen for the 'data' event to receive decompressed data
compressedStream.on('data', data => {
  console.log(`Decompressed data: ${data.toString()}`);
});

Conclusion

Node.js Brotli is a powerful tool for developers who need to compress and decompress data in their Node.js applications. With its high compression ratios and easy-to-use API, Brotli is an excellent choice for anyone who needs to optimize their application's network performance or storage footprint.
