What is tmp?

The tmp npm package is used for creating temporary files and directories in a Node.js environment. It helps manage and clean up temporary files automatically.

What are tmp's main functionalities?

Temporary File Creation

This feature allows you to create a temporary file. The library provides a callback with the path and file descriptor, and a cleanup callback to remove the file when it's no longer needed.

const tmp = require('tmp');
tmp.file(function _tempFileCreated(err, path, fd, cleanupCallback) {
  if (err) throw err;
  console.log('File: ', path);
  console.log('Filedescriptor: ', fd);
  // If we don't need the file anymore we could manually call the cleanupCallback
  // But that is not necessary if we didn't pass the keep option because the library will clean after itself.
  cleanupCallback();
});

Temporary Directory Creation

This feature allows you to create a temporary directory. Similar to temporary file creation, it provides a path to the directory and a cleanup callback.

const tmp = require('tmp');
tmp.dir(function _tempDirCreated(err, path, cleanupCallback) {
  if (err) throw err;
  console.log('Dir: ', path);
  // Manual cleanup
  cleanupCallback();
});

Synchronous File Creation

This feature allows for synchronous creation of a temporary file name. It returns the name directly without the need for a callback.

const tmp = require('tmp');
const name = tmp.tmpNameSync();
console.log('Temporary filename: ', name);

Synchronous Directory Creation

This feature allows for synchronous creation of a temporary directory. It returns an object with the directory name.

const tmp = require('tmp');
const dir = tmp.dirSync();
console.log('Temporary directory: ', dir.name);
