What is a component in React Native?

Ever since the development of technology and especially of software and applications, developers have been looking for efficient ways to create products. Over the years, many tools and technologies have been developed to facilitate this process. React Native, a JavaScript-based open source framework, is one of those solutions. It allows developers to create robust Native mobile applications for both Android and iOS platforms. But what is a component in React Native and how does it help in building applications? How does this framework make product development easier and quicker? Can you do more with it than just developing traditional mobile applications?

The growing complexity of today’s mobile applications and the need for quick delivery and efficiency have made React Native a viable choice for developers. React Native is known for its architecture based on components, a feature that allows developers to create cross-platform applications with a single code base. According to a survey conducted by Statista, React Native is the most popular open source framework among developers who develop mobile applications (Statista, 2018). This indicates the rising demand for React Native and its components in the market and speaks volumes about its potential.

But what is a component in React Native? A component can be defined as an individual unit of code which helps in assembling a larger application. It is a small piece of the code which is the building block of the app, and can be reused in many different applications. In React Native, components help enhance efficiency, maintainability, and scalability during product development. It enhances efficiency by breaking down complex tasks into smaller and simpler parts which can be used across multiple frameworks and platforms mainly Android and iOS.

In this article, you will learn more about the components of React Native and how they contribute to building applications. In addition to the components, you will also explore other features of React Native such as the UI components, APIs, and more. Additionally, you will find out the important reasons why React Native is the go-to framework for developers today and how its components help build elegant applications.


React Native is a popular framework for creating mobile applications that run on both Android and iOS devices. A component is a building block of an application, it is a self-contained module that provides a specific set of functionality. Components are reusable and can be used to compose larger portions of an application. React Native components are written using JavaScript, with native components implemented through a “bridge” between the native language and JavaScript. This bridge enables the native code to be called from JavaScript.
Interface – Components also define the UI elements of an application, such as buttons, text boxes, and other widgets. They define how a user interacts with the application.
State – A component often includes state, which is defined as the set of properties that define how an application behaves. For example, components can define variables that track whether the user is logged in or not, or how many items are in a shopping cart.
Functionality – Components can also define functions, which are pieces of code that are executed when a user performs a certain action or clicks a certain widget. These functions can modify the state of an application and typically involve making a call to an external service or API.
Props – Props are used to pass data from one component to another. A parent component can pass data to a child component by passing a prop as an argument. Props are immutable, meaning they cannot be changed by the component using them.
Lifecycle – React Native components have a lifecycle, meaning they are created, modified, and destroyed in a specific order. This order affects the functionality of the component and can influence how its state and props are managed.
In summary, a React Native component is a reusable, self-contained piece of software that provides both UI elements and functionality, and can be used to compose larger parts of an application. Components define state, props, functions, and a lifecycle that connects them all. Understanding how components work is essential for developing successful React Native applications.

Introduction to React Native Components

Introduction to React Native Components

React Native components are the building blocks of a React Native application. Components are individual pieces of code that define how a given app should look and behave. React Native allows developers to define both the UI and the system behavior in one language, JavaScript, for simple and intuitive development.

What Are Components?

Components are like chunks of an application that contain specific logic, like a UI element or a network request. They can be re-used throughout the application, so developers can easily create consistent designs and behavior. Usually, a component will render some UI elements, determine how they respond to user interactions, and handle any data it needs to take in and output.

Components in React Native

In React Native, components are created using ES6 classes. They can take in arguments, referred to as ‘props’ to determine their behavior. There are two main types of components available in React Native: components, and containers. Components are the visual elements, like buttons and labels, while containers gather data and logic around them.
One of the key advantages of React Native is the ability to create reusable components. Developers can create these components to define how an application looks, with stylesheets, and how it behaves, with JavaScript. By updating the state of a component via its props, developers can create applications that automatically re-render when data updates, making it easier to keep the application code up-to-date.
React Native also makes use of ‘third-party components’, which are components that are not part of the core React Native codebase, but can still be imported and used within an app. These components can range from UI elements to data providers to network requests. By making use of third-party components, developers can avoid writing boilerplate code and can instead focus on writing the code that is specific to their application.
