rn-shadow-steroid

A Clojure library with a few functions-steroids for react native app, can be used only with shadow-cljs

Usage

{:dependencies [[rn-shadow-steroid "0.2.8"]]}

Register root reagent component in app registry

(:require [steroid.rn.core :as rn])

(defn root-comp []
  [rn/view
   [rn/text "HELLO WORLD"]])

(defn init []
  (rn/register-comp "app-name" root-comp))

Register root component with HOT RELOAD

(:require [steroid.rn.core :as rn])

(defn root-comp []
  [rn/view
   [rn/text "HELLO WORLD"]])

(defn init []
  (rn/register-reload-comp "app-name" root-comp))

shadow-cljs.edn

{:source-paths ["src"]

 :dependencies [[rn-shadow-steroid "0.2.6"]]

 :builds       {:dev
                {:target     :react-native
                 :init-fn    app.core/init
                 :output-dir "app"
                 :devtools   {:after-load steroid.rn.core/reload
                              :build-notify steroid.rn.core/build-notify}}}}

Now each time you change your code it will be hot reloaded keeping an app state. NOTE react native fast refresh should be turned off

   [rn/view {:style {:padding 5 :flex-direction :row :align-items :center}}
    [rn/image {:style {:width 50 :height 50 :margin 5 :border-radius 25 :margin-right 10}
               :source {:uri image-url}}]
    [rn/view {:style {:flex 1}}
     [rn/text {:style {:font-size 18 :font-family "Inter" :flex-shrink 1}} title]
     [rn/text {:style {:font-family "Inter" :flex-shrink 1 :color :gray :margin-top 5}
               :number-of-lines 2}
      description]]]])

(defn myapp []
    [rn/view {:style {:flex 1 :background-color :white}}
     [rn/text {:style {:font-size 22 :align-self :center :margin 10 :font-family "Inter"}}
      "MyApp"]
     [list/flat-list {:data data-vector :render-fn item-render}]])

React Navigation with HOT RELOAD

Navigation container component

yarn add @react-navigation/native

[steroid.rn.navigation.core :as rnn]
rnn/navigation-container
rnn/create-navigation-container-reload

Stack components

yarn add @react-navigation/stack

[steroid.rn.navigation.stack :as stack]
stack/stack

Bottom tabs components

yarn add @react-navigation/bottom-tabs

[steroid.rn.navigation.bottom-tabs :as bottom-tabs]
bottom-tabs/bottom-tab

Safe area components

yarn add react-native-safe-area-context

[steroid.rn.navigation.safe-area :as safe-area]
safe-area/safe-area-provider safe-area/safe-area-consumer safe-area/safe-area-view

EXAMPLE

`yarn add @react-navigation/native @react-navigation/stack @react-navigation/bottom-tab react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-masked-view/masked-view`

`cd ios; pod install; cd ..`

  (:require [steroid.rn.core :as rn]
            [re-frame.core :as re-frame]
            [steroid.rn.navigation.core :as rnn]
            [steroid.rn.navigation.stack :as stack]
            [steroid.rn.navigation.bottom-tabs :as bottom-tabs]
            [clojurernproject.views :as screens]
            [steroid.rn.navigation.safe-area :as safe-area]
            steroid.rn.navigation.events))

(defn main-screens []
  [bottom-tabs/bottom-tab
   [{:name      :home
     :component screens/home-screen}
    {:name      :basic
     :component screens/basic-screen}]])

(defn root-stack []
  [safe-area/safe-area-provider
   [(rnn/create-navigation-container-reload
     {:on-ready #(re-frame/dispatch [:init-app-db])}
     [stack/stack {:mode :modal :header-mode :none}
      [{:name      :main
        :component main-screens}
       {:name      :modal
        :component screens/modal-screen}]])]])

(defn init []
  (rn/register-comp "ClojureRNProject" root-stack))

Notice that we register root-stack without hot reload but create navigation-container-reload.

re-frame navigation events steroid.rn.navigation.events

After steroid.rn.navigation.events has been required once, re-frame events are registered and you can use them for navigation

(re-frame/dispatch [:navigate-to :modal])

(re-frame/dispatch [:navigate-to :basic])

(re-frame/dispatch [:navigate-back])

ENJOY!
