Hello,
I am trying to apply “namespacing” to my app.
Inside ./src/Examples/RamdomDie.elm I have the example from https://guide.elm-lang.org/effects/random.html . The module starts with
module Examples.RandomDie exposing (main)
In index.html body I have
<script>var app = Elm.Examples.RandomDie.init({...
Browser console has error :
Uncaught TypeError: Cannot read property 'RandomDie' of undefined
Thoughts on what I have done wrong?

What is defined on the Elm
variable? Try logging it to the console in your browser.
I just discovered my issue was with bad arguments on elm-live.
I was telling it to use src/*.elm, which was not globbing down into src/Examples, even though the elm-live output ends a startup with
elm-live:
Watching src/**/*.elm.
So, that’s confusing on elm-live.
Anyway, seems to be working now with this command
elm-live src/**/*.elm --open --start-page=index.html -- --output=main.js

Great, glad to hear it’s working. You might want to open an issue for elm-live, if that message isn’t accurate.
Since I’m the author of that log line in elm-live
, I thought I’d chime in
elm-live
picks up the directories it’s going to watch from your elm.json
. The log line correctly says that it’s going to watch for file changes recursively in src
. But , you’re supposed to give it the name of your main module as the first argument, src/Examples/RandomDie.elm
in your case. It’s very curious that it somehow works with src/**/*.elm
instead.
So elm-live
doesn’t support having multiple main modules?
Apparently it does. Just tried it with elm-live src/Main1.elm src/Main2.elm -- --output elm.js
.
