What's the clojurescript equivalent of "abc"[1]?

I've just found charAt, that might work as a substitute, but I'm still curious if it's possible to do this?

there's (nth abc 1) but that just calls charAt

Can someone explain how to get a REPL to develop https://github.com/JulianBirch/cljs-ajax ?

do protocol names get munged by advanced optimizations?

ex cljs$core$IPrintWithWriter$

of course

Hi. I have a question about global-exports. The example at https://clojurescript.org/news/2017-07-30-global-exports uses a library which has a default export (React). But my library exports multiple named exports (`MarkerMap`, RouteMap, SetCoordinateMap and SetMultipleCoordinatesMap and no default export). My sollution so far:

{:file     "resources/lib/kartklient.js"
 :provides ["markerMap" "routeMap" "setCoordinateMap" "setMultipleCoordinatesMap"]
 :global-exports '{markerMap MarkerMap
                   routeMap RouteMap
                   setCoordinateMap SetCoordinateMap
                   setMultipleCoordinatesMap SetMultipleCoordinatesMap}}

(ns dhp-client.helpers.kartklient
  (:require [reagent.core :refer [adapt-react-class]]
            [markerMap :as markerMap]
            [routeMap :as routeMap]
            [setCoordinateMap :as setCoordinateMap]
            [setMultipleCoordinatesMap :as setMultipleCoordinatesMap]))

(def marker-map (adapt-react-class markerMap))
(def route-map (adapt-react-class routeMap))
(def set-coordinate-map (adapt-react-class setCoordinateMap))
(def set-multiple-coordinates-map (adapt-react-class setMultipleCoordinatesMap))

Hello, i’ve got a warning when I evaluate this form: (cljs.core/MapEntry. 1 2)

------ WARNING - :fn-arity -----------------------------------------------------
 Resource: :1:1
 Wrong number of args (2) passed to cljs.core/MapEntry
--------------------------------------------------------------------------------

@pbaille why are you constructing it directy? it takes a third hash argument, you can pass nil

I like to use map-entries to represent linked things, not always in the context of a map

@thheller thank you for your help

does anyone know if I can include a plain javascript file as part of a clojurescript (`*.cljc`) release to clojars ? I am not entirely sure of how this would play on the consumer side … would they have to have the same configuration as my local one for it to work ? will it work at all ? :thinking_face:

@carocad You can include a deps.cljs file in a JAR which points to a JavaScript file (as a foreign lib)

(The ClojureScript compiler scans for deps.cljs)

Quick question -- when we initialize-db, how and from where does the map get populated from?

this is the event initialize-db command i have. wondering how it fills in the data. I guess I am wondering what happens behind this code?

I’m guessing you’re talking about using re-frame. There’s no magic; if you want to initialize the DB, you can create an event (like you have there) and have it return the map of initial data

it looks like that code there assumes there’s some db namespace that has a default-db var in it which has the map of initial data

and then somewhere else in the code, when it renders the application it must call (dispatch-sync [::initialize-db])
