I will keep supporting the projects that I have open sourced. If you have used any of my projects, for yourself or your business, I'd love your support through Github sponsors. You can also try to convince your employer to sponsor as a business.

Introduction

Jumpstart building robust apps using React Native and TypeScript with most commoly needed tools already setup. Just yarn install and get going from respective IDEs.

Routing and Navigation
- Native Tabbed navigation using React Native Navigation v7
- Side / Drawer Menu support
State Management using Flux Architecture
- Redux
- Redux-Thunk middleware - side-effect handling
Atomic Design pattern
- The structure of the app is inspired by atomic design pattern.
- Widgets / Elements: Build your own Design Language System with these building blocks.
  - Typography: Base Typography setup - Color, Font, LAYOUT, CTA, FONTS, TEXT, TEXT_INPUT
  - elements: <BUTTON_DEFAULT> or <CTEXT>. They are custom elements that have default properties like font, size and so on.
```
<CTEXT style={GLOBAL.CTA.Style.primaryText}>{title}</CTEXT>
```
  - widgets: Any component providing a complete functionality. E.g. carousels component, banner component, etc.
```
<Category componentId={componentId} title={locale.Categories} />
```
Type Definitions
- Type definitons for actions, reducers, store, components and more.
Built-in Splash screen
Hermes and Flipper integrations
Code Lint
- Airbnb's JS Linting

Getting Started

Make sure node version installed is >=12.x.x. Then install using yarn (or npm):

yarn install

Start the Metro Bundler:

yarn start

iOS

One time. Move to ios folder and install pods:

cd ios && pod install

Launch application from XCode (Command + R) Or launch from Terminal:

yarn ios
# runs the following command. change device name here
# `npx react-native run-ios --simulator='iPhone 11'`

Android

Start an Android Simulator from:

Android Studio > Tools > AVD Manager > Run any device

Similarly, run from Android Studio itself Or from Terminal:

yarn android
# runs the following command
# react-native run-android --variant=Debug

Commands

	Remark
`yarn start`	Starts metro bundler
`yarn ios`	Starts iOS app. Start metro bundler first
`yarn android`	Starts Android app. Start metro bundler and Android emulator first
`yarn lint`	linting
`yarn lint:fix`	tries to fix linting issues automatically
`yarn build:android:debug`	Android debug build
`yarn build:android:release`	Android release build

Cheat Sheet

iOS Launch Screen

XCode -> Project Folder -> Click on `Images.xcassets` -> Click on `LaunchScreen`

Change the 3 images here to set the new launch screen for iOS.

Android Launch Screen

`./android/app/src/main/res/drawable-*` folders

Change the images the drawable-* folders to set the new launch screen for Android.

M1 support

Some additional steps may be required for project to work on M1.

Disable Rosetta in Terminal
Install ffi

sudo arch -x86_64 gem install ffi

Re-install dependencies

arch -x86_64 pod install

Now try and run CocoaPods.

Single Screen vs Tabbed Based Navigation

The application launches with a splash screen, and then moves to a tabbed based navigation. Splash screen is a good place to fetch data / build application launch logic like getting user token from API or Async Store, load persist state etc.

For Single screen application, replace this tabbed based navigation with a single screen - just home, or simply use the splash screen to setup the app, may be with a burger menu.

Renaming the App

You might also want to rename the app for your own use. Follow any of the links below.
