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

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const gzip = new Gzip();

  // This will create a .gz such that when ungzipped by a tool such as 7-Zip,
  // it will create "qa_data/hamlet.xml".
  try {
    await gzip.compressFileAsync('qa_data/hamlet.xml', 'qa_output/hamlet.xml.gz');
  } catch {
    console.log(gzip.lastErrorText);
    return;
  }

  // Call CompressFile2 to explicitly specify the ungzip path
  // For example, this will create a .gz such that when ungzipped by a tool such as 7-Zip,
  // it will create "hamlet.xml".
  const embeddedExtractPath = 'hamlet.xml';
  try {
    await gzip.compressFile2Async('qa_data/hamlet.xml', embeddedExtractPath, 'qa_output/hamlet2.xml.gz');
  } catch {
    console.log(gzip.lastErrorText);
    return;
  }

  console.log('Success.');
