Deleting Files with Deno

If you are working with Deno, you may need to delete files at some point in your code. Deleting a file with Deno is a simple process that can be done using the built-in Deno.remove() method.

Example Code:

try {
  await Deno.remove("/path/to/file.txt");
  console.log("File deleted successfully.");
} catch (err) {
  console.error("Error deleting file:", err);

The Deno.remove() method takes a single argument, which is the path to the file that you want to delete. If the file is successfully deleted, the method will return void.

If there is an error while deleting the file, such as the file not existing or permissions issues, an error will be thrown. You can catch this error using a try-catch block, as shown in the example code.

Other Methods for Deleting Files

In addition to using Deno.remove(), you can also delete files using other methods in Deno. These include:

  • Deno.unlink(): This method is similar to Deno.remove(), but it only works on files and not directories. You can use this method if you know that the path you are passing is a file and not a directory.
  • Deno.removeSync() and Deno.unlinkSync(): These are synchronous versions of the above methods. They work the same way as their asynchronous counterparts, but they block the main thread until the operation is complete.

It is recommended to use the asynchronous methods whenever possible, as they do not block the main thread and allow your code to continue running while the operation is being performed.
