Tempfile is a server specifically for managing temporary files. New random
file are created in a temporary location and are automatically cleaned up when
the requesting process exits.
Because tempfile creation is stateful, the :tempfile application must be
started in order to use the Tempfile module.
This is almost entirely a port of plug's Plug.Upload module. There are
some slight modifications around file naming, but the GenServer itself is
derived wholesale from Plug.
If you want a more robust alternative look at briefly, which also provides temporary file handling (but has a less discoverable name).
The package can be installed from hex as tempfile:
-
Add tempfile to your list of dependencies in
mix.exs:def deps do [{:tempfile, "~> 0.1.0"}] end
-
Ensure tempfile is started before your application:
def application do [applications: [:tempfile]] end
Create a new temporary file with a basename and extension:
{:ok, path} = Tempfile.random("tempfile.txt")
File.write!(path, "I am a text file")When the calling process exits the file will be removed automatically.
