For JavaScript developers who want to learn React Native. Learn how to build not just an app, but a Product.

About this Course

Where does React Native fall within app categories? Should you invest in it?

The Value of Building Real-World Apps in React Native

Once you get the hang of the ecosystem around React Native, building apps will be the easy part. We need to consider storyboarding - the art of the right way to build apps.

Storyboarding a React Native App's Components and Flow

Starting from the ground up? We'll look at the structure of the boilerplate code. An opinionated way to build apps, inspired by several apps in production.

Bootstrapping a React Native App With Boilerplate

Set up, build and run the boilerplate code, with a battle-hardened template and all the necessary tools already integrated.

How to Start Building a React Native iOS and Android App

Getting Started

Stacked app or tabbed navigation, drawer menus and modals, and what's the best place to load user sessions, and other application data.

Getting Started With React Native Navigation

Set the app's launch screen and icons. Learn what image to put in native and what to bundle with React Native. Set the tab bar icons.

Navigation and Screens

Atomic design is a mental model of how the UI should be built and laid out. It is at the core of how we are going to build our apps.

Intro to Atomic Design Patterns [with examples]

To build a design system we need to start by defining a typography; defining the fonts, colors and icons of the app.

Building a Typography Design System in React Native

Global styles help lay the design structure the app should follow. We'll extend our typography from the previous lesson to define styles, mainly for atoms, molecules and organisms.

How to Set Global Styles in React Native

Should we use images or SVGs? Should we be putting them in the React Native bundle, or on native and save OTA bandwidth? Let's look at the best practices.

SVG vs PNG: Which Image Format to Use in a React Native App

We'll look at the Atomic design pattern's atoms and molecules; what they are and how they help build the design system of the app.

Customizing React Native Elements With Global Style

Built using atoms and molecules, Organisms are the complex components that deliver specific features. They are at the core of an app that delivers a consistent UX.

Combining React Elements Into Widgets

What happens when we press a button on an app vs when we press a button on a web page? That difference is User Experience.

React Native Cheat Sheet

Bonus Content

With React Native, the most important thing is to understand the ecosystem and how it comes together to create an app. By understanding the overall architecture, we will be able to take the full of advantage the platform.

The course will start by covering the fundamentals like setting up the navigation, setting up the screens, styles, and the UI elements, before moving on to more advanced topics such as state management, crash/error reporting, setting up analytics and middlewares, debugging, and performance optimizations. We will also learn how to avoid/fix frame drops - possibly the most watched parameter of any UI application.

We will also build a Design System and will follow the [Atomic Design Pattern](https://atomicdesign.bradfrost.com/chapter-2/) of building layouts. A Design System primarily consists of three parts:
- UI Inventory and Patterns
- Typography
- Spacing and Styles

We will cover these in detail through the modules of the course. We will also learn about the React Native best practices, how to avoid rabbit holes, and focus on building a performant app.

**This is an opinionated way of building apps with React Native**. The fundamentals discussed in the course, like Atomic Design Pattern and Design System, can be applied to building any UI application, not just ones using React Native.

## One Complete App

The course comes with one complete eCommerce sample app that is discussed through the modules of the course.

## Up-to-date

The course builds on an open-source boilerplate template and is kept up to date with React, React Native and dependent library versions. It is also updated with the latest APIs and libraries that are introduced, like Hooks, hermes, flipper etc.

## Why this course

React Native for JavaScript Developers using TypeScript is based on years of experience in building React Native apps on production. The open-source boilerplate code discussed in the course is the platform for multiple apps on App Store and Play Store today. One of them being a Unicorn.

We will take a **Product** based development approach to building apps. React Native abstracts out a lot of platform specific nuances, so wouldn't focusing on building the app as an experience make the most sense. The design pattern will help us exactly with that, and we will put together a structure that is both scalable and extensible. This architecture also helps keep the design separate from the development.

At the end of this course, you will not only be able to build real-world apps with React Native, but also have the fundamentals of building any enterprise UI application.

newline Guide to React-Native for JavaScript Developers

 is designed for developers who have been working with JavaScript for a long time, and want to understand how it serves as an excellent platform to build apps using React Native. The course will start by covering fundamentals like navigation, setting up screens, styles, and UI elements, before moving on to more advanced topics such as state management, crash and error monitoring, setting up analytics and middlewares, debugging, and performance optimizations.

Like any open source framework/platform there is a wide range of tools and libraries available to users of React Native. We will cover these topics using a set of time-tested, industry standard tools and libraries. Although developers are free to substitute any of these tools with their own choices, I've used these libraries on multiple apps in production and  

With React Native, the most important thing is to understand how these pieces come together to create an app. During the course, we're going to build an app using an open source boilerplate code. 

However, this course is not just designed for those looking to jump into building apps using React Native. Unlike "jumpstart" courses that throw everything at you like a cookbook, we will take a step-by-step approach, teaching the different elements and how they come together, always keeping an eye on best practices and performance. We will be taking a 

 development approach to building apps; thinking about those things we need to take care of to achieve native levels of performance on both Android and iOS platforms.

The course does not expect you to have any prior experience in developing native apps. I only started building native apps a couple of years ago. It is 

 required for building React Native apps. The boilerplate code takes care of the base setup and everything needed to build your app. As you go through the course, you will realize there is no code written on the native side.

This course is aimed at those JavaScript developers who work on JavaScript frameworks but do not know React Native, and want to learn how to build not just an app but a
