with-local-tmp-dir/dist/index.js

Creates a temporary folder inside cwd, cds inside the folder, runs a function, and removes the folder. Especially useful for testing.

import chdir from '@dword-design/chdir';
import tmp from 'tmp-promise';
export default (async (...args) => {
  let options = args.find(arg => typeof arg === 'object');
  options = {
    dir: process.cwd(),
    tmpdir: process.cwd(),
    unsafeCleanup: true,
    ...options
  };
  const callback = args.find(arg => typeof arg === 'function');
  if (callback) {
    return tmp.withDir(context => chdir(context.path, callback), options);
  }
  const context = await tmp.dir(options);
  const back = chdir(context.path);
  return () => {
    back();
    return context.cleanup();
  };
});
