Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

React Native

import { Gzip } from '@chilkat/react-native'

async function chilkatExample() {
  // This example demonstrates how to compress a string and save the result
  // directly to a Gzip (.gz) file.

  const gzip = new Gzip();

  // The string to be compressed:
  const inputStr = 'The quick brown fox jumps over the lazy dog.';

  // Compress the string using UTF-8 and write to a file:
  try {
    await gzip.compressStringToFileAsync(inputStr, 'utf-8', 'output.gz');
  } catch {
    console.log(gzip.lastErrorText);
    return;
  }

  console.log('Compression successful.');
  console.log('Gzip file written to output.gz');
}
