Clojurians Log v2

is it possible to run advanced build in watch mode? trying it now and the output doesn’t seem to be optimized (not using :debug flag)

no, not possible. due to the sometimes excessive build times of :advanced that simply isn't practical. much better to click one button or run one command when you are actually sure you want to build

should I use a linter? and which one?

no clue, your choice. I've never used one for long, too much noise regarding macros in the ones I tested

that's why I am asking here, seems like an unsurmountable hurdle

I think the most popular one currently is #clj-kondo

yeah, ale for vim has autoconfigure for it, also for joker, I tried both because it would help me as a beginner, i think, but it's probably not going to happen today. difficult to configure all the macros and i am not even sure what to do when it's not a macro

Should we expect the grand total of the build report optimised column from something like shadow-cljs run shadow.cljs.build-report app report.html to be about the same size as the target app.js I wonder? It’s falling short for me and so I’m trying to understand what I’m missing.

within a certain percentage yes, it isn't 100% accurate but close enough

Thanks @thheller. I’ll make a gist to show you what I mean - I’m quite a long way short.

build config would help. don't know what you are doing to the build 😛

html report is also more helpful since it groups stuff

jar | cljs/core.cljs | 750.5 KB

looks like you are maybe using :simple? or pseudo-names?

shouldn't be that large otherwise

Sorry - my mistake - I had dine a calva jack-in so was looking at a development app.js. Makes more sense after another build.

… and you were right - I did have optimisations simple.

I've not had too many issues with clj-kondo. Dealing with macros is pretty easy. In my re-frame project, the only macro I have a special lint rule for is this

{:lint-as {reagent.core/with-let clojure.core/let}}

If you have custom macros that don't match any known macro linters I think you can tell the linter to ignore them, or perhaps tell it to :lint-as the comment macro

Hey, I am using shadow-cljs to run cljs on aws lambda. I want to use the npm package jsonwebtoken. The problem is when I build my lambda for prod the node_modules are not included in the output folder so just uploading the index.js file leads to a runtime error that jsonwebtoken could not be found. I copied node_modules manually and zipped it all up which worked but is tedious. Is this expected? I feel like I am doing something wrong and shadow-cljs would take care of that for me. shadow-cljs.edn:

Hi everyone, I'm using shadow-cljs v2.12.5 for a react-native app The react-native console is showing error

@jaime.sangcap in ~/.shadow-cljs/config.edn you can configure :local-ip "192.168.0.184" (or in your shadow-cljs.edn local config as well)

you can post process the :output-to file with something like https://github.com/vercel/ncc

but honestly it is better to just copy the node_modules you need

ok, thanks. I’ll probably add a copy node_modules step to my build script

just to clarify, you mean to copy the whole node_modules folder right?

no

create a folder with a package.json including the pacakges you need

run npm install --production

copy the resulting node_modules

I think the AWS has a section for best practices regarding this

just check their docs

ah, thank you 🙂

Awesome! Thanks a lot, it works. Shame on me, it is stated in the docs https://shadow-cljs.github.io/docs/UsersGuide.html#repl-trouble-react-native 😅
