In the case in which portal doesn't work, in the browser console I get errors like:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

This is due to the git source missing the compiled js artifact for the cljs code

Projects that use ClojureScript are hard to use directly as git deps.

thank you @U04V70XH6! Is there something that I could do to workaround this? I mean, in general?

In theory, @U1G869VNV could add a "prep" step that could run the build (locally) and produce the artifacts needed. See https://clojure.org/reference/deps_and_cli#prep Although, given that there's no build.clj in the project, I don't know that could be automated yet -- and it would rely on you as a git deps user having all the necessary tooling installed locally in order to run that build step (node, npm, shadow, etc I believe).

But for some projects, yes, the deps prep approach is relatively straightforward -- where they just need Java code compiled, or some Clojure code AOT'd.

Portal does https://github.com/djblue/portal/blob/master/dev/tasks/build.clj#L13-L27, but it needs a little tweaking to making it clj/prep-able :thinking_face:

https://github.com/djblue/portal/commit/d02528afba2fb57498597680009ef30b0979527d should add prep support, let me know what happens

Might need to do clj -X:deps prep :aliases '[:dev]' if portal is brought in via :extra-deps

This is what happens now if I try to start a repl in a project in which I included a git dependency on portal:

That was entirely because I didn't understand how it was supposed to work 😂 . Now that I know, I'll post in the main thread
