What is the best practice for replacing a directory in it's contents using javascript?

Question

I've written quite a few node scripts over the years using CJS but am in the process of converting a few of my projects to ESM. One thing that occurs to me is that I may have some problems with synchronicity now. I have not had any issues yet but I'm curious to know, is the following code still good practice?

The purpose of the code is to delete and recreate a folder and it's files and then write a file into it, which is a common task I need to do for this project.

// Replaces old CJS __dirname with variable mapped to project root
const __dirname = dirname(resolve('./package.json'));

if (!existsSync(resolve(__dirname, output))) {
    mkdirSync(resolve(__dirname, output));
  } else {
    // If the output dir exists, delete all files in it so we can start fresh
    rmSync(resolve(__dirname, output), { force: true, recursive: true });
    mkdirSync(resolve(__dirname, output));
  }
  // Create the root README file
  writeFileSync(resolve(__dirname, output, 'README.md'), rootReadMe, 'utf8');

Everything does work but I suspect that it's only a matter of time before I run into issues.
