I execute "lein cooper" and "electron ." and hello-world window appear. but It has only white content.

Although I changed root-component in ui/core.clj, It has only white background.
figwheel mark appear but It is same.

I can't figure out how to set the window title. I tried

1.updating index.html <title> tag,
2. (.setTitle ^js/electron.BrowserWindow @main-window "My App")
3. (.on ^js/electron.BrowserWindow @main-window "page-title-updated" (fn [e] (.preventDefault e)))

But none of those seem seem to work. I know this is more about Electron than cljs-electron, but I think it would be helpful to cljs-electron users :)

Hi @Gonzih ,

I really love the work you've put into this template, this is amazing.

But when I run it with the Emacs + nrepl based Figwheel repl the devConsole throws this error. It's not causing any hinderance but I'd really like to know what's expected by React-render method.

Thanks

Warning: react.inc.js 

 render(): Rendering components directly into document.body is discouraged, since its children are often manipulated by third-party scripts and browser extensions. This may lead to subtle reconciliation issues. Try rendering into a container element created for your app.

Is there any way to use advanced optimization with electron?

Just wanted to say this project was very helpful for getting me up and running. Any chance you could document a good route for packing this application for production.

How would one connect a repl via cider?

I downloaded whole repo into my local, then install electron via npm install electron -g.
after that , I did "lein deps" in the right folder, then I try lein cooper
but terminal shows error
"

"
any configuration I should do before running lein cooper?

my env: windows 10 ,

Really enjoying this project as a way of introducing myself to cljs and electron.

However it's a bit unclear how the electron.core calls the electron api in the renderer process. For example how would we be able to utilise the web-frame options or create menu objects?

Defining .-web-frame in the same way as .-BrowserWindow causes a compile error in the foreman task.

I just cloned the project and performed all the steps in the README. On Windows, I needed to delete the env/fast-trampoline lines from the PROCFILE, and then it worked.

Only problem I'm having is a figwheel error related to output-dir, which I find baffling because I don't see any duplication in output-dir in the config, despite the error message. Have you encountered this?:

Hi there & thanks for this project!

When I clone this repo and run the default example, then try to change text in ui/core.cljs (for instance, replace the "Electron" string, I get the following compiler error:

I don't need access to the file system just now, and once I comment out the run-process form and delete the the input where it is used, everything is fine, so it isn't a blocker for me or anything. Just wanted to let you know. 😃

While starting on a brand new project, the foreman ui process fails to work correctly.
This happens with any project name.
The version of Java is openjdk version 1.8.0_111.

Hey there!

Great project. Very easy to get up and running.

One issue I'm having: Figwheel doesn't appear to be working correctly.

After saving my code, I wait a few seconds and then see the CLJS logo appear in the bottom-left corner, but the UI doesn't change. I need to hard-refresh in order to see my changes appear in the UI.

Any tips in chasing this one down?

Many thanks!

I'm really enjoying playing around with this template, but need some help, probably because I am still rather new to the cljs tooling ecosystem used here.

I have an idea for a program I would like to use for work, but it requires somewhat intensive processing of a large number of pdfs. Based on this article, I think I should have that happen in a separate process that the main process communicates with.

So I added a "pdf_src" directory, put in a pdf.core namespace, and added the following to the :builds defined in project.clj :
{:source-paths ["pdf_src"] :id "pdf-dev" :compiler {:output-to "resources/pdf.js" :output-dir "resources/public/js/pdf-dev" :optimizations :simple :pretty-print true :cache-analysis true}}

I added pdf: env LEIN_FAST_TRAMPOLINE=y lein trampoline cljsbuild auto pdf-dev to the procfile.

My goal is to put the code for the background tasks in the pdf.js file and then fork a node process to run that file from main.

But running lein cooper gives me a whole stack of compilation errors.

Compiling ["resources/pdf.js"] failed. clojure.lang.ExceptionInfo: null #:clojure.error{:phase :compilation} at cljs.util$compilation_error.invokeStatic(util.cljc:23) at cljs.util$compilation_error.invoke(util.cljc:22) at cljs.closure$write_js_QMARK_.invokeStatic(closure.clj:2058) at cljs.closure$write_js_QMARK_.invoke(closure.clj:2047) at cljs.closure$source_on_disk.invokeStatic(closure.clj:2064) at cljs.closure$source_on_disk.invoke(closure.clj:2060) at cljs.closure$build$fn__6208.invoke(closure.clj:3020) at clojure.core$map$fn__5851.invoke(core.clj:2755) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:51) at clojure.lang.Cons.next(Cons.java:39) at clojure.lang.RT.next(RT.java:709) at clojure.core$next__5371.invokeStatic(core.clj:64) at clojure.core$dorun.invokeStatic(core.clj:3142) at clojure.core$doall.invokeStatic(core.clj:3148) at clojure.core$doall.invoke(core.clj:3148) at cljs.closure$build.invokeStatic(closure.clj:3020) at cljs.closure$build.invoke(closure.clj:2919) at cljs.build.api$build.invokeStatic(api.clj:208) at cljs.build.api$build.invoke(api.clj:189) at cljs.build.api$build.invokeStatic(api.clj:195) at cljs.build.api$build.invoke(api.clj:189) at cljsbuild.compiler$compile_cljs$fn__709.invoke(compiler.clj:61) at cljsbuild.compiler$compile_cljs.invokeStatic(compiler.clj:60) at cljsbuild.compiler$compile_cljs.invoke(compiler.clj:48) at cljsbuild.compiler$run_compiler.invokeStatic(compiler.clj:168) at cljsbuild.compiler$run_compiler.invoke(compiler.clj:129) at user$eval838$iter__886__890$fn__891$fn__917.invoke(form-init7740181582868617844.clj:1) at user$eval838$iter__886__890$fn__891.invoke(form-init7740181582868617844.clj:1) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:51) at clojure.lang.RT.seq(RT.java:531) at clojure.core$seq__5387.invokeStatic(core.clj:137) at clojure.core$dorun.invokeStatic(core.clj:3133) at clojure.core$doall.invokeStatic(core.clj:3148) at clojure.core$doall.invoke(core.clj:3148) at user$eval838.invokeStatic(form-init7740181582868617844.clj:1) at user$eval838.invoke(form-init7740181582868617844.clj:1) at clojure.lang.Compiler.eval(Compiler.java:7176) at clojure.lang.Compiler.eval(Compiler.java:7166) at clojure.lang.Compiler.load(Compiler.java:7635) at clojure.lang.Compiler.loadFile(Compiler.java:7573) at clojure.main$load_script.invokeStatic(main.clj:452) at clojure.main$init_opt.invokeStatic(main.clj:454) at clojure.main$init_opt.invoke(main.clj:454) at clojure.main$initialize.invokeStatic(main.clj:485) at clojure.main$null_opt.invokeStatic(main.clj:519) at clojure.main$null_opt.invoke(main.clj:516) at clojure.main$main.invokeStatic(main.clj:598) at clojure.main$main.doInvoke(main.clj:561) at clojure.lang.RestFn.applyTo(RestFn.java:137) at clojure.lang.Var.applyTo(Var.java:705) at clojure.main.main(main.java:37) Caused by: java.lang.Exception: Could not write JavaScript nil ... 51 more Subprocess failed

What am I missing? Any help would be much appreciated.

Above all, thank you very much for this great info.

I know that this question is not appopriate here.

I am so sorry about that but I have no choice but to write here.

My question is as follows.

Live-reloading frontend-dev works well by using figwheel but
do you happen to know how to live-relaod electron-dev?

see issue opened:

kouphax/lein-cooper/issues/10
bhauman/lein-figwheel/issues/624

any hints on resolving? Thanks

Hi,

I have cloned the repo, ran npm install electron-prebuilt -g but then when I run the lein cooper command i get the following stack trace:

If I run: lein trampoline cljsbuild auto electron-dev and lein trampoline figwheel frontend-dev separately it works fine until I want to make any changes and re-run the application. It will then hang on Waiting for changes..

Apologies for my gap in knowledge. I am new to using clojure in this way.

Hi @Gonzih , have another question regarding the template.

Clearly this is a production level template - what I really want to know is to create a bare-essential template. I've tried experimenting with the various configurations but I can't get past the dev.core hurdle.

Could you, please help me create a much simpler template, for practice.

Thanks, looking forward to the response.
