React Native Template - TypeScript

An opinionated React Native Starter Kit with React Native Navigation + Redux + Airbnb TSLint to build iOS and Android apps using TypeScript

The project has been setup based off RN Getting Started and instructions from Microsoft's Github TypeScript React Native Starter repo.

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
  • Tabbed navigation using React Native Navigation v7
  • Side Menu support
• State Management using Flux Architecture
  • Redux
  • Redux-Thunk middleware
• Widgets / Elements Build your own design system with these building blocks.
  • elements: <BUTTON_DEFAULT> or <CText>. They are custom elements that have default properties like font, size and so on.
  • widgets: Any component providing a complete functionality. E.g. carousels component, banner component, etc.
• Typography
  • Base Typography setup - Color, Font, LAYOUT, CTA, FONTS, TEXT, TEXT_INPUT
• Code Lint
  • Airbnb's JS Linting

Disclaimer: This is an opinionated approach to building apps with RN. The project structure is inspired by multiple production apps built by the contributors.

Getting Started

Make sure node version installed is >=10.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.

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.
