Writable Monaco Editor

You can also use the Import Code Snippets syntax combined with the {monaco-write} directive, to link your Monaco Editor with a file on your filesystem. This will allow you to edit the code directly in the editor and save the changes back to the file.

<<< ./some-file.ts {monaco-write}

When using this, be sure to back up your files beforehand, as the changes will be saved directly to the file.
