How to use repl?

[janat08]

I don't see code for connecting to the lein-cljsbuild, and I can't tell how you'd use a worker file to test it.

[janat08]

Lein compile on my machine doesn’t run, I had to call plug-in for compile.

[janat08]

The plug-in docs expect some repl specific code.

Hey @janat08,

the example worker should be a fully working examples (it get's tested with github actions here on every push).

Does that example help you? Let me know if you hit any particular error. I can definitely confirm that the most seamless experience for a repl has been Calva in vscode for me, after trying numerous others + alternative build tools.

[janat08]

3 the lein repl command actually errors as things stand so I added calva as prerequisite.

[janat08]

Do you have to start a repl server too?

[janat08]

Because simply trying to load the cljs doesn’t work.

Could you share how you're starting the repl? It sounds like you're starting it from the command line, but that way we could double check the arguments provided on startup

[janat08]

I just installed calva extensions and asked it to load file in output tab i think, or the repl window it opens. Then I tried following lein-cljs help text which suggests requiring and running repl server using browser, but I'm using gitpod (cloud ide) so it connect to localhost as it doesn't exist but is instead on cloud (usually how reloading and websockets don't work with cloud ides). Did you at all do anything to make lein-cljsbuild work like put repl server command and packages, because if I remember I might have had to install the repl server package.

Any thoughts? They also came up with miniflare so arguably this repo is just about repl integration. Does JS interop affect repl capabilities?

Hey @janat08,

I definitely recommend using node rather than the browser as I had issues with the browser version many times, however you should be able to run it with lein + cljs in calva basically out of the box. With calva I didn't have to add any additional dependencies to lein except for the ones listed here

Regarding your second point, the goal of this package was to provide clojure-friendly interfaces for building a worker and providing the glue between javascript and clojurescript. One it's main objectives was to get minimise the amount of boilerplate needed to get a clojurescript worker running.

It is not meant to replace any of the worker toolchains. The simulate-worker function is provided to allow for a repl friendly way to test a worker, without any external dependencies. It is purely a helper however.
