So I've put this together in a Nix Flake to serve as a decent launch point for
|
||||
quick-and-dirty Elixir applications.
|
||||
|
||||
Here ya go!
|
||||
`mix.exs` is necessary for locking dependencies as used by Nix's `mixFodDeps`
|
||||
and is used for nice things like code reloading by Phoenix, so not _quite_ as
|
||||
"single file" as my inspiration.
|
||||
|
||||
So here ya go!
|
||||
|
||||
```bash
|
||||
elixir main.ex
