does cljs-http can used for react-native?

Using Reagent, how do you add an attribute such as "checked" or "readonly" to an input? Usually I would do this [:input {:attribute "value"}] but I can't simply do {:checked}

[:input {:checked “checked”}]

or true

Ah okey, that's how I'm doing it now

actually any non false value I believe

Alright cool, maybe true would look better 🙂 thanks!

your welcome 🙂

Another related thing, whenever I precheck the checkbox it gets stuck that way and I'm unable to uncheck it. Any clue about why that could be?

Turns out I should use :defaultChecked instead 🙂

Does anybody use yada library for user authentication? Fox example, i want that my view A was only accessible to a user that has a role A.

@ramon.rios Yada takes :access-control {:authentication-schemes [(check-user-role-fn)]}.. see if this might help

Thanks @lucio

Actually I believe that for roles you'd need :authorization rather than :authentication ..

@ramon.rios It's well covered here:

I have a very simple ClojureScript Electron app (compiled via Figwheel Main) which is working fine when I use none or simple optimizations, but fails with TypeError: Cannot read property 'dc' of undefined when I compile with advanced optimizations. Any suggestions for how to debug what might be causing this?

Are you using any 3rd party libraries, especially 3rd party JavaScript libs?

Right now I’m using virtually nothing (just re-frame plus whatever comes along with Electron) as I’m just trying to get a base to start from.

Interesting :thinking_face: So probably there’s some bundled JS with Electron itself. Are you building from the cljs-electron base, or rolling your own? (https://github.com/Gonzih/cljs-electron)

I’m using the pre-built Electron. This is my package.json:

{
  "name": "opentrack",
  "version": "0.1.0",
  "main": "resources/node/app/app-main.js",
  "scripts": {
    "start": "electron ."
  },
  "devDependencies": {
    "electron": "^6.0.11"
  },
  "dependencies": {
    "ws": "^7.1.2"
  }
}

(about as simple as it can be!)

That looks different from the cljs-electron lib, you might want to check it out.

@paulbutcher Adding :infer-externs true should might fix the issue

Hmm - I’ll take a look. I’m trying to get something up and running with Figwheel Main though…

Ah - thanks Lu - I’ll give that a go.

(what does infer-externs do?)

It creates inferred_externs.js with all the symbols that the compiler is not supposed to chunk under optimization advanced

In your cljs code you might need to add a tag ^js to what you want to be preserved.. i.e. (defn my-func [^js x] ...)

Hmm - I’m still getting the same error with :infer-externs true 😞

Add the ^js

How do I know what I want to be preserved? I’ve no idea what bc started out as referring to?

But add it to what?

I am afraid you have to guess by commenting out some code.. but logically if you're using some javascript interop I would naturally look at that and see what javascript functions/objects you are using

I have virtually no code! The entirety of my app (it’s the app that’s causing the problem not the renderer) is:

(ns opentrack.app.core
  (:require [cljs.nodejs :as nodejs]))

(def Electron (nodejs/require "electron"))
(def BrowserWindow (.-BrowserWindow Electron))
(def app (.-app Electron))

(defonce win (atom nil))

(defn create-window []
  (reset! win (BrowserWindow. (clj->js {:webPreferences {:nodeIntegration true}})))
  ; (.openDevTools (.-webContents @win))
  (.loadFile @win "resources/index.html"))

(.on app "ready" create-window)

That’s it - there’s no other code whatsoever.

I’m guessing you need an externs file for Electron

You’ve got me curious, I’m going to pull down the latest cljs-electron and see if that has any issues building with advanced compilation turned on.

I’ve not tried cljs-electron. Like I said - I’m trying to get Figwheel Main working (and it’s working brilliantly with either none or simple optimizations)

But I guess it’s an interesting counterpoint!

Well, to see whether it's electron comment out everything but Electron and BrowserWindow variables.. if it still complains you are certain it's electron

I’ve just pulled cljs-electron and it does seem to work OK with advanced optimizations.

I guess I’ll see if I can move that across to Figwheel Main successfully, and will probably learn something (whether it has the same problem or not!)

@lucio, @manutter51 - so that was informative and I can now make my code work. But I’m not entirely sure I understand why (I would appreciate your thoughts!). Here’s my modified (and now working) code:

(ns opentrack.app.core)
  ; (:require [cljs.nodejs :as nodejs]))

(def Electron (js/require "electron"))
(def BrowserWindow (.-BrowserWindow Electron))
(def app (.-app Electron))

(defonce win (atom nil))

(defn create-window []
  (reset! win (BrowserWindow. (clj->js {:webPreferences {:nodeIntegration true}})))
  ; (.openDevTools (.-webContents @win))
  (.loadFile ^js/electron.BrowserWindow @win "resources/index.html"))

(.on app "ready" create-window)

The two changes are switching from (nodejs/require ...) to (js/require ...), and adding ^js/electron.BrowserWindow

I think I understand why the ^js/electron.BrowserWindow is necessary, but I’ve no idea why nodejs/require doesn’t work but js/require does?

Hi all, are there any noteworthy libraries for dom manipulation that do not rely on react?

From my understanding js/ is the way you can access external libraries. In other words, the global variables of the library you are importing are all available under js/

Indeed - I understand that. But why doesn’t cljs.nodejs/require work? It’s part of the ClojureScript API: https://cljs.github.io/api/cljs.nodejs/require

Hi there, I have advanced compilation turned on for production build so I'm in the process of switching over dot property access to use gobj/get. However, I'm running into the following error:

(let [map ((gobj/get map-ref "getMap"))]
                         (js/console.log (gobj/get map "addLayer")) ; logs a function as expected
                         ((gobj/get map "addLayer") tile-src) ; error: cannot read property "addLayer" of undefined. This should be invoking the method that is logged in the line directly above
                         (.addLayer map tile-src)) ; this works fine

Am I blind here?

Error building classpath. Could not transfer artifact com.bhauman:figwheel-main:jar:0.2.3 from/to clojars (): Range Not Satisfiable (416)

@kwladyka 416 is a http status code for partial downloads. maybe you have a half-aborted file sitting in ~/.m2?

check ~/.m2/repository/com/bhauman/figwheel-main

rm -r ~/.m2/repository/com/bhauman/figwheel-main/0.2.3 solved the issue. Thank you. Like always 🙂

Is there a defacto library to use in CLJS for webworkers?
