How to do a release/deploy build of a clojurescript app? - clojure

I'm ready to release my clojurescript app. Currently i do lein ring uberjar to create my jar, which does build cljs, but i dont see any documentation on how to do a release build-- do i need to do any concat-ing/minifying/bla bla bla? Are there special release options?
Here is my cljsbuild setup in my project.clj->
{
:builds [{:id "dev"
:source-paths ["src/analyticsjs"]
:figwheel false
:clean-targets ^{:protect false} ["resources/public/js/compiled" "target"]
:compiler {:main "analyticsjs.core"
:asset-path "/js"
:output-to "resources/public/js/cljs.js"
:output-dir "resources/public/js"}}
]
}
All help is appreciated. Thanks!

I was directed in the clojurians slack channel to add :optimizations :advanced inside my :compiler map, which worked.

How to handle the new HTTP configuration for shadow-cljs?

I have been using Clojure, ClojureScript, lein, shadow-cljs, Emacs,
and CIDER to work on a Clojure/ClojureScript dynamic web app project.
Usually, I build the project by executing the command
cider-jack-in-cljs in Emacs, choosing shadow-cljs, then shadow
for REPL type, and, finally, app for the building option.
Things were working fine. I was used to watching changes on the UI on
localhost:3005.
But, an answer from a previous question indicated that the
project was using an old (and deprecated) HTTP configuration for
shadow-cljs.
On shadow-cljs.edn we had:
{:source-paths ["src" "dev"]
:dependencies ...omitted..
:nrepl {:port 8230
:nrepl-middleware [dirac.nrepl/middleware]}
:builds {:app {
:devtools {:after-load app.core/main
:http-root "public"
:http-port 3005
:preloads [shadow.cljs.devtools.client.hud
day8.re-frame-10x.preload
dirac.runtime.preload
devtools.preload]}
}}}}}
After the build was complete, I would see the live application on
localhost:3005. The mini-buffer would direct me to see the
rendered page on the browser.
On shadow-cljs.edn, now, we have:
{:source-paths ["src" "dev"]
:dependencies ...omitted..
:nrepl {:port 8230
:nrepl-middleware [dirac.nrepl/middleware]}
:builds {:app {
:devtools {:after-load app.core/main
:preloads [shadow.cljs.devtools.client.hud
day8.re-frame-10x.preload
dirac.runtime.preload
devtools.preload]}
:dev-http {3005 "public"}
}}}}}
However, the workflow for development is different.
Emacs mini-buffer redirects me on the browser to a different address:
http://localhost:9630/dashboard
Also, old localhost:3005 does not work, even though it is mentioned
on :dev-http {3005 "public"}.
1 - What is the new workflow to change the code and see the changes?
2 - Why is port localhost:3005 not working anymore even though it is mentioned in the source code?
3 - What is the purpose of the dashboard?
:dev-http is a top-level config. It is not part of a build config. It needs to sit at the same level as :nrepl and :builds.
{:source-paths ["src" "dev"]
:dependencies ...omitted..
:nrepl {:port 8230
:nrepl-middleware [dirac.nrepl/middleware]}
:dev-http {3005 "public"}
:builds
{:app
{...
:devtools
{:after-load app.core/main
:preloads
[day8.re-frame-10x.preload
dirac.runtime.preload
devtools.preload]}}}}}}

How to create a multi-page application with Figwheel and Leiningen?

I have a simple Figwheel application which is built with Leiningen.
I want to have multiple pages in it:
index.html should use the code from hello-figwheel.core.
page2.html should use the code from hello-figwheel.page2
I assume I have to somehow modify the project.clj file:
:compiler {:main hello-figwheel.core
:asset-path "js/compiled/out"
:output-to "resources/public/js/compiled/hello_figwheel.js"
:output-dir "resources/public/js/compiled/out"
:source-map-timestamp true
;; To console.log CLJS data-structures make sure you enable devtools in Chrome
;; https://github.com/binaryage/cljs-devtools
:preloads [devtools.preload]}}
How can I tell Leiningen to compile
hello-figwheel.core to resources/public/js/compiled/hello_figwheel.js and
hello-figwheel.page2 to resources/public/js/compiled/page2.js?
There is a similar question. The difference to this one is that Leiningen is used to run Figwheel.
Update 1: I added the following to the project.clj file:
{
:id "page2"
:source-paths ["src"]
:compiler {
:output-dir "resources/public/js/compiled/page2"
:output-to "resources/public/js/compiled/page2/main.js"
:main hello-figwheel.page2
:asset-path "js/compiled/out"
:source-map-timestamp true
;; To console.log CLJS data-structures make sure you enable devtools in Chrome
;; https://github.com/binaryage/cljs-devtools
:preloads [devtools.preload]}
:figwheel {:on-jsload "hello-figwheel.page2/on-js-reload"
;; :open-urls will pop open your application
;; in the default browser once Figwheel has
;; started and compiled your application.
;; Comment this out once it no longer serves you.
:open-urls ["http://localhost:3449/page2.html"]}
}
When I run lein figwheel, the REPL is unable to connect to my web application:
It says Prompt will show when Figwheel connects to your application, but it never happens.
Also, if I open http://localhost:3449/page2.html in the browser, update page2.cljs, and refresh the page in the browser, the changes are not visible there.

figwheel build can't find my core cljs namespace

I'm trying to use figwheel build for my project. I use the latest versions of libs and my leiningen version is 2.5.1. My build file looks like this:
(defproject figwheel-issue "1.2.3"
:plugins [[lein-cljsbuild "1.0.6"]
[lein-figwheel "0.3.3"]]
:dependencies [[org.clojure/clojurescript "0.0-3269"]
[org.clojure/clojure "1.7.0-beta3"]]
:cljsbuild {
:builds [{ :id "dev"
:source-paths ["src"]
:figwheel true
:compiler {
:main myproject/core
:hashbang false
:asset-path "js/out"
:output-to "resources/public/js/example.js"
:output-dir "resources/public/js/out"
:optimizations :none}}]})
Normal build works ok. So when I run:
lein cljsbuild once
I get:
Successfully compiled "resources/public/js/example.js" in 0.873 seconds.
But when I try to run:
lein figwheel
Figwheel build can't seem to find my core namespace:
Compiling "resources/public/js/example.js" failed.
clojure.lang.ExceptionInfo: failed compiling file:target/figwheel_temp/dev/figwheel/connect.cljs
at clojure.core$ex_info.invoke (core.clj:4591)
Caused by: clojure.lang.ExceptionInfo: No such namespace: core, could not locate core.cljs, core.cljc, or Closure namespace "core" at line 1 target/figwheel_temp/dev/figwheel/connect.cljs
at clojure.core$ex_info.invoke (core.clj:4591)
Any ideas what could be wrong? I created a minimal github project which demonstrates the issue here:
https://github.com/auramo/figwheel-build-issue
Problem was the namespace, it should be:
:main myproject.core

Dependencies in a clojurescript with leiningen

I am seriously pulling my hair right now! I am a total noob at clojure: I can't seem to be able to get a simple clojurescript compilation done without this error:
ERROR: JSC_MISSING_PROVIDE_ERROR. required "clojure.core.async" namespace never provided at /home/jldupont/workspace/$someproject/target/cljsbuild-compiler-0/domain2/main.js line 4 : 0
I've got the following project.clj file:
(defproject $someproject "0.1"
:description "some project..."
:dependencies [[org.clojure/clojure "1.5.1"]
[org.clojure/clojurescript "0.0-2030"]
[org.clojure/core.async "0.1.267.0-0d7780-alpha"]
]
:plugins [[lein-cljsbuild "0.3.2"]]
:cljsbuild {
:builds [{:id "domain2"
:source-paths ["src/cljs/model2/domain"]
:compiler {:output-to "src/assets/js/model2/domain/domain2.js"
:optimizations :advanced
:pretty-print true}
}
]
}
)
Everytime I use lein cljsbuild auto I get the error quoted above.
Please help!
Update
I've looked in my ~/.m2 directory and the dependencies ( in this case core.async ) are present.
Update 2
It would appear that it is the Google Closure Compiler that spews out this error message. Not sure how to provide it a path to the dependencies...
As mentioned in my comment above: if you want to use core.async with ClojureScript you have to require the namespace cljs.core.async (instead of Clojure's clojure.core.async).

How can I deploy a Leiningen template to Clojars?

I have created a Leiningen project on my local machine which I then turn into a template by doing:
lein create-template webdb
: Then I install the template:
cd webdb
lein install
: which allows me to create projects based on the template locally:
lein new webdb anewproject
: Everything works fine up to here. However if I try to deploy the template to clojars using:
cd webdb
lein deploy clojars
: then whenever I try to use the clojars profile to create a template I get an error:
lein new org.clojars.zubairq2/webdb anothernewproject
: gives the error:
Could not find metadata org.clojars.zubairq2/webdb:lein-template/maven-metadata.xml in local (/Users/faroukzquraishi/.m2/repository)
Failure to find org.clojars.zubairq2/webdb:lein-template/maven-metadata.xml in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced
Failure to find org.clojars.zubairq2/webdb:lein-template/maven-metadata.xml in http://clojars.org/repo/ was cached in the local repository, resolution will not be reattempted until the update interval of clojars has elapsed or updates are forced
This could be due to a typo in :dependencies or network issues.
Could not find template org.clojars.zubairq2/webdb on the classpath.
: does anyone know what I am doing wrong here?

your upload seems to have worked and the result is here:
https://clojars.org/webdb/lein-template
you can make a project like this:
arthur#a:~$ lein new webdb newproject
Retrieving webdb/lein-template/0.1.0-SNAPSHOT/lein-template-0.1.0-20130618.143034-5.pom from clojars
Retrieving webdb/lein-template/0.1.0-SNAPSHOT/lein-template-0.1.0-20130618.143034-5.jar from clojars
To use a lein plugin, you must make it a dependency it in your .lein/profiles.clj
Since you project is on clojars, if you add its dependency it should be available to you.
