Deleting files
Removing files and directories is a common task. Deno has a number of functions for this task.
In the case that we want to remove a simple file, we can simply call Deno.remove with the filename as a parameter
await Deno.remove("example.txt");There is also a sync version of the api available
Deno.removeSync("example.txt");If we want to remove a directory, we could do exactly what we did above. If the directory has contents, the call would error out. If we want to recursively delete the contents of a directory, we should set recursive to true
await Deno.remove("./dir", { recursive: true });A common pattern is to remove a file or directory only if it already exists. The correct way of doing this is by just doing it and trying to catch any NotFound errors.
try {
await Deno.remove("example.txt");
} catch (err) {
if (!(err instanceof Deno.errors.NotFound)) {
throw err;
}
}
