let tinify = await npm("tinify");
let fs = await import("fs");
let selectedFiles = await getSelectedFile();

tinify.key = env.TINIFY_API_KEY;

let filePaths = selectedFiles.split("\n");

for (let filePath of filePaths) {
  let directory = path.dirname(filePath);
  let extension = path.extname(filePath);
  let originalFileName = path.basename(filePath);
  let suffix = "-optimized";
  let newFileName = originalFileName.replace(extension, suffix + extension);

  fs.readFile(filePath, (err, sourceData) => {
    if (err) throw err;
    tinify.fromBuffer(sourceData).toBuffer((err, resultData) => {
      if (err) throw err;
      fs.writeFile(`${directory}/` + newFileName, resultData, (err) => {
        if (err) throw err;

  });
}

Get your api key on tinify.com/dashboard/api (assuming you're logged in) and add it to ~/.kenv/.env file like so:

# ...
TINIFY_API_KEY=your_key

let isHD = originalFileName.includes("@2x");
let newFileName = isHD
  ? originalFileName
      .replace("@2x", "")
      .replace(extension, `${suffix}@2x${extension}`)
  : originalFileName.replace(extension, `${suffix}${extension}`);
