NodeJS: How to compress string to Buffer or Base64 using Brotli

const zlib = require('zlib');

// Sample string to compress
const stringToCompress = "This is a sample string to be compressed using Brotli in Node.js";

// Convert the string to a Buffer
const bufferToCompress = Buffer.from(stringToCompress, 'utf-8');

// Compress the buffer using Brotli
zlib.brotliCompress(bufferToCompress, (err, compressedBuffer) => {
  if (err) {
    console.error('Error compressing the string:', err);
    return;
  }

  console.log('Compressed Buffer:', compressedBuffer);

  // Optional: Convert the compressed buffer to a Base64 string for display
  const compressedString = compressedBuffer.toString('base64');
  console.log('Compressed String (Base64):', compressedString);
});

// Assume compressedBuffer is the buffer you got from the previous example

zlib.brotliDecompress(compressedBuffer, (err, decompressedBuffer) => {
  if (err) {
    console.error('Error decompressing the string:', err);
    return;
  }

  const decompressedString = decompressedBuffer.toString('utf-8');
  console.log('Decompressed String:', decompressedString);
});
