If you use Ellie for quick non-interactive experiments like I do when playing with different language features or trying out API ideas, you probably find yourself either deleting the default code that a new Ellie is populated with, or somewhat awkwardly adding bits to it.

Update: Bill St. Clair showed me a much shorter boilerlate:

module Main exposing (main)

import Html exposing (text)


main =
    text "hello"

That’s it! main doesn’t have to be a Program value - it can be an Html value too.

Here is a link to the Ellie with this code: https://ellie-app.com/3yWZqvt8RYTa1.

Original boilerplate below.

I kept doing that for a while, and finally I decided to document a minimal boilerplate for static content:

module Main exposing (main)

import Browser
import Html exposing (text)


main : Program () () Never
main =
    Browser.sandbox { init = (), view = \_ -> text makeStr, update = \_ _ -> () }


makeStr : String
makeStr =
    Debug.toString [ 1 ]

Since it’s only a few lines, it’s easy to add your own code. To produce output, just modify the makeStr value.
