Learn React Native: Essential Skills for Aspiring Developers

Introduction

Companies and organizations from different industries have adopted the mobile-first policy. This approach prioritizes mobile devices for any digital content. Whether a website or an application, it needs to be mobile-responsive. However, mobile users are categorized into two groups: Android and iOS. Developing two different code versions for a single software is never feasible. It requires too much upfront investment, let alone the complexities and development time. Truth be told, companies are looking forward to innovating this approach. This is where React Native comes into play!

This JavaScript-based open-source platform supports hybrid app development. In other words, developers need to deploy a single codebase for both Android and iOS users. Owing to this, the importance of this framework has skyrocketed recently. The demand for skilled React Native developers has also increased significantly worldwide. However, you must learn the skills and gain practical knowledge to enter this career. That’s why enrolling in a course on React Native for beginners is the best option. 

What is React Native?

React Native was first deployed in 2015 under the guidance of Facebook. It was an open-source platform for mobile application development. This framework is based on React, which is also a JavaScript-based library collection. However, the main difference lies in the fact that it allows React components to interact with native APIs seamlessly. In other words, developers can extend the native functionalities of the OS using it. On top of this, only a single codebase is required for both Android and iOS. It greatly reduces the code complexity and execution time. 

Most React components can be reused for better code organization. Apart from this, frontend developers can seamlessly connect with native elements. As a result, mobile applications can deliver a rich omnichannel user experience across all platforms. React Native utilizes the hierarchy model of ReactJS. It clearly describes the control flow from parent to child components for better user control. Hence, scaling the components individually becomes easier. 

React Native Basics: Understanding the Core Concepts

Knowing the core terminologies of React Native for beginners is essential. Only then will you be able to implement the same in practical applications. Besides, this JavaScript-based framework has gained immense importance in recent times. So, if you want to establish a flourishing career, the following are the main areas you should focus on. 

Setting Up the Development Environment

Knowing how to set up the dev environment is a key part of React Native basics. Any well-structured course curriculum will give you a brief walkthrough. This lets you download all the necessary libraries and connect the platform with the required APIs. Besides, if you don’t have a proper setup, you won’t be able to write the codes. What’s more, the workspace is required for debugging in React Native. So, you should first learn the ways to set up the development environment for React Native. 

JSX and Component-Based Architecture

React Native has a component-based architecture. These are reusable, self-contained, and modular. Every component is responsible for rendering a small UI part. Also, it can manage its own state and data logic for better independent functioning. In React Native, components can be segregated into two major types, namely:

1. Class components: These are solely responsible for rendering the UI.
2. Functional components: These accept props as inputs and return a React component. 

The components follow a hierarchical relationship. Every parent component is connected to one or many child components. Data can be passed only from the parent to the child component and not vice versa. Another important core concept of React Native for beginners is the JSX. Although it is based on JavaScript, you cannot use the same HTML tags for the JSX. Rather, you need to use the proper syntax, like <ScrollView>, <Image>, <View>, and so on. 

Some of the basic JSX features you will learn are:

1. Usage of components in place of the HTML tags
2. Wrapping up the code in the parent components
3. Inline JavaScript expressions
4. Self-closing tags

State and Props in React Native

In React Native, data management and UI rendering are done dynamically. To do so, the two essential concepts used are state and props. 

1. Props or Properties are read-only data. It is passed from the parent to the child component. They can be customized externally, ensuring dynamic rendering and component reusability. These are immutable and cannot be changed inside the child component.
2. State, on the other hand, describes the dynamic changes in the React components. Once it changes, the concerned component will re-render. 

Navigation and UI Components

You will also learn about navigating the application using different React Native components. You should know the ways to render different UI components using the JSX syntax of this framework. Additionally, you will be guided on using React components to extend native APIs for seamless functionality. 

React Native for Beginners: Essential Skills to Master

Handling User Inputs and Forms

Forms are an integral part of React Native that you will need to learn as a beginner. These are online web pages that collect details from the UI. All these details are gathered through the Text Input component of React. Once captured, their states and values can be managed internally for dynamic execution. 

API Integration and Data Fetching

You will also have to know about API integration with the React components. This will help you master React Native for beginners easily. Developers often need to extend the native functionalities of the OS. For this, they are required to integrate native APIs with their JavaScript codebase. Also, APIs will be required to fetch data from different interfaces. 

Using React Native Libraries and Third-Party Packages

It’s important to understand the React Native basics, including the third-party packages and the libraries. Since it is based on ReactJS, you will have access to different built-in libraries. These functions can be used to design an interactive and feature-rich UI with ease. Also, you will have to import different third-party packages through the Node Package Manager. These packages will help you customize the React code according to the backend architecture. 

Debugging and Performance Optimization

One of the most important skills you should develop as a React Native professional is debugging. Reading the code and finding the errors is crucial for seamless functional flows. For this, you should have detailed knowledge about JSX and the React components. Also, you need to learn the state and props of different components to check the rendering process. Only then will you be able to optimize the code’s performance for faster execution. 

How to Get Started with Learning React Native?

Best Resources to Learn React Native

Learning the React Native basics is the first rock you have to climb for your glorious career. You can gain knowledge about the key concepts from numerous sources, like:
