React Native

Create Self-Extracting Executable (Windows-only)

Demonstrates how to create a Windows self-extracting EXE. React Native

import { Zip } 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 zip = new Zip();

  // Chilkat for React Native has no AbortCheck callback.  To cancel a pending ...Async call,
  // call zip.abort() (Chilkat notices it within heartbeatMs milliseconds); the promise then rejects.
  // Called with the percent completed (0..100) while an ...Async method runs.
  zip.onPercentDone = (pctDone) => {
    console.log(`Percent Done: ${pctDone}`);
    // Explicitly abort at 25% or greater.
    // Remove this to allow for the HTTP download to run to completion.
    if (pctDone > 25) {
      zip.abort(); // cancel the Chilkat method in progress
    }
  };
  zip.onProgressInfo = (name, value) => {
    console.log(`${name}: ${value}`);
  };

  // Initialize the zip object.  Because we're creating
  // a self-extracting EXE in this example, the filename
  // passed to NewZip will never actually be created.
  try {
    zip.newZip('notUsed.zip');
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // Append a directory tree.  The AppendFiles does
  // not read the file contents or append them to the zip
  // object in memory.  It simply appends references
  // to the files so that when WriteExe (or WriteZipAndClose,
  // or WriteZip, etc.) is called, the files are compressed
  // and added to the archive.
  const recurse = true;
  await zip.appendFilesAsync('c:/temp/a/*', recurse);

  // Write "sfx.exe"
  try {
    await zip.writeExeAsync('c:/temp/sfx.exe');
  } catch {
    console.log(zip.lastErrorText);
    return;
  }
