State Management in React Native

State is one such thing, which has been a part of debate in React Native communities. In my opinion, State is not a debatable topic. In fact, it’s super relevant and useful. 

Especially if you are building a complex application like eCommerce, state is something that keeps on changing a lot from frame to frame or browser to browser. 

In this article, we will understand about React Native State Management and how useful is it in order to build complex React Native applications. 

Let’s dive right in!

What exactly is a State?

The Internet is full of technical terminologies when it comes to understanding the state. Let me do you one better by explaining it in layman terms. 

Picture yourself with a toy box full of your favorite toys. Each toy has a particular condition that it can be in, such as sitting still, leaping around, or producing amusing sounds.

The term “state” in programming refers to a special box that records how objects are acting or what they are doing at any given time. It aids the computer in remembering the state of various programme elements.

For instance, a computer or mobile game you’re playing needs to know if you won or lost, how many points you have, and where your character is on the screen. The state has all of that data preserved.

So, just like your toy box helps you organize and keep track of your toys, the state helps the computer keep track of what’s happening in the program and make sure everything works smoothly!

What is State in React Native?

Similar to the toy example we learned above, the term “state” in the context of React Native refers to the information that controls how components in an application behave and appear. Throughout the app’s lifespan, state management is the process of handling and modifying this data. Your app will be more dependable and robust if you use proper state management to make sure that data is updated, synchronized, and consistent across various components.

The Importance of Effective React Native State Management

Efficient state management plays a pivotal role in maintaining a responsive and scalable React Native application. Following are some reasons why state management in React Native is a crucial part of building applications:

  • Better Performance: Effective state management reduces needless component re-rendering, which improves app performance. Re-rendering without control might make your software sluggish and have a bad effect on the user experience.
  • Code Maintainability: Using transparent state management techniques makes your codebase easier to maintain and comprehend. A well-organized state management system makes it easier to troubleshoot and add features as your project expands.
  • State Reusability: When a state is properly designed, it may be applied to a variety of components, cutting down on duplication and improving code efficiency. This reuse encourages a more well-organized development process.
  • Scalability: Scalable state management makes sure that if your programme changes and adds new features, it can do so without causing large interruptions or conflicts.

State Management Techniques in React Native

React Native offers several state management techniques, each catering to different use cases and preferences. Let’s explore some common React Native state management techniques:

1. Local Component State

The simplest form of state management involves using local component state. React Native components have a built-in “state” object that allows you to store and manage data specific to that component. While suitable for small apps with minimal state requirements, this method may become unwieldy for larger applications.

2. React Context API

The React Context API allows you to create global state variables that can be accessed by any component in your app. It eliminates the need to pass props through intermediary components, making state sharing more efficient. Although great for mid-sized projects, managing complex state interactions might be challenging.

3. Redux

Redux is a popular state management library widely used in React Native applications. It follows a centralized store approach where all application state is stored in a single “store.” Components can access the state and subscribe to updates, making data flow more predictable. Redux shines in large-scale applications with extensive state management requirements.

4. MobX

MobX is another state management library that adopts a more flexible approach compared to Redux. It uses observable data structures, allowing components to automatically update when the underlying data changes. MobX is known for its simplicity and is an excellent choice for projects of all sizes.

5. Recoil

Recoil is a relatively new state management library introduced by Facebook. It focuses on providing easy and intuitive APIs for managing state in React applications. Recoil’s key strength lies in its ability to manage complex state structures with minimal boilerplate code.

Best Practices for Effective State Management in React Native

Regardless of the state management technique you choose, following best practices will ensure optimal results:

1. Keep State Localized

Avoid cluttering your global state with data that is only relevant to a specific component. Keeping state localized ensures better isolation and reduces the risk of unintentional side effects.

2. Opt for Immutability

Immutability helps maintain a predictable state by preventing direct modifications to the state data. Instead of mutating state variables, create new ones with the desired changes. Libraries like Immutable.js can assist in implementing immutability.

3. Use Selectors

In complex state management systems, selectors act as efficient filters for accessing specific pieces of state data. They enhance performance by reducing unnecessary re-renders caused by changes irrelevant to a particular component.

4. Leverage Asynchronous Actions

In real-world apps, many state changes might involve asynchronous operations like API calls. Use middleware like Redux Thunk or Redux Saga to handle such asynchronous actions gracefully.

Summing Up

State management is a critical aspect of React Native app development. Choosing the right technique and adhering to best practices will undoubtedly lead to a more performant and maintainable application. Whether you opt for local component state, Redux, MobX, Recoil, or any other approach, always aim to keep your state organized, scalable, and reusable. By doing so, you can ensure that your React Native app stands out and delivers an exceptional user experience, setting it on the path to outrank other websites in its domain.

Remember, while state management is vital, it’s just one piece of the puzzle. Alongside top-notch content, focus on other aspects like responsive design, accessibility, and app performance to create a well-rounded and competitive product in the market. Happy coding!

What is React Native?

React Native is a Javascript framework to create authentic, natively rendered mobile applications for iOS and Android. While React Native is based on React, Facebook’s JavaScript toolkit for designing user interfaces, it focuses on mobile platforms rather than browsers. In other words, web developers can now leverage a JavaScript library they already know and love to build mobile applications that genuinely look and feel “native.” Furthermore, React Native simplifies the process of building for both Android and iOS by allowing developers to share the majority of their code across platforms simultaneously.

What is React Native Development?

React Native development is the design and development of cross platform mobile applications like iOS and Android, using a single codebase. The key concept behind React Native is that it allows developers to write components using JavaScript, similar to web development with React.js. These components are then compiled into native code for each platform, allowing the app to run as a true native application on the respective devices.

React Native Application Development Architecture

Consider creating a mobile application that is compatible with both iPhones and Android phones. The problem, though, is that each platform (iOS and Android) speaks a different language, just like people from other countries do. Therefore, you would normally need to create two unique versions of the app, one for each platform, if you wanted your app to function on both types of phones.

React Native now steps in to save the day! React Native functions as a kind of magical translator that enables you to create the JavaScript code for your app and then have it transform it into the particular language that each platform can understand. This allows you to develop apps for both iOS and Android using the same codebase.

React Native leverages following key architectural concepts to develop cross-platform applications:

  • Virtual DOM: Similar to React for web applications, React Native uses a Virtual DOM. This Virtual DOM is a lightweight copy of the actual DOM and allows React Native to efficiently manage updates and optimize performance.
  • JavaScript and Native Modules: The core of React Native is written in JavaScript, but it can interact with native modules written in Java (for Android) and Objective-C or Swift (for iOS). This combination enables seamless communication between JavaScript and the native components of the device.

Key Components of React Native Architecture

To understand how React Native apps are built, let’s take a look at some essential components:

  • View: The View component is like a container that helps structure and style other components. It acts as a fundamental building block for creating user interfaces.
  • Text: The Text component allows developers to display text on the screen. It supports various text-related features like font styles, text alignment, and text wrapping.
  • Image: The Image component is used to display images in the app. It supports local and remote images and offers options for resizing and caching.
  • StyleSheet: The StyleSheet component is used for styling React Native components. It uses a similar syntax to CSS but is optimized for mobile devices.
  • Flexbox: React Native uses Flexbox to provide flexible layout options for arranging components. It helps in creating responsive and adaptive UI designs.
  • Props and State: Props and State are two essential concepts in React Native. Props are used to pass data from parent to child components, while State allows components to manage their internal data.
  • Touchable Components: React Native provides touchable components like TouchableOpacity and TouchableHighlight, which allow developers to add touch-based interactions to elements.
  • ScrollView and FlatList: ScrollView and FlatList are components used for efficiently rendering lists of data. FlatList is particularly useful for long lists as it only renders the items currently visible on the screen.

Architectural Patterns in React Native

When developing complex React Native applications, it’s essential to follow robust architectural patterns. Some popular patterns include:

  • Flux: Flux is a unidirectional data flow architecture that helps in managing the flow of data in the app. It consists of actions, stores, and a dispatcher.
  • Redux: Redux is a predictable state container that centralizes the application’s state and allows components to access and modify the state using actions.
  • MobX: MobX is a state management library that focuses on making state management simple and reactive. It automatically tracks state changes and updates the components accordingly.

Best Practices of Building Scalable React Native Application

In order to build a scalable React Native Application, developers must take the following best-practices into account:

  • Folder Structure: A clean codebase is easier to maintain and allows for more effective teamwork amongst different engineers thanks to a well-organized folder structure.
  • Code Splitting: By dividing the software into smaller pieces, code splitting enables users to download only the parts of the app they actually need. Performance and loading times are enhanced as a result.
  • Performance Improvement: A smooth user experience must be delivered, which means performance must be optimized. The performance of the application can be greatly improved by employing methods like image optimisation, lazy loading, and minimizing render-blocking.
  • Handling Navigation: Any mobile app must have good navigation. The right navigation library must be chosen by developers, and seamless screen transitions must be implemented.
  • State Management: State Management is important to store and manage the data that elements need in order to render the values. In particular, the data or value is kept in the component’s state object, which alters depending on the action, and the components re-render themselves.

Cost of Hiring React Native Developers

The cost of hiring a React Native developer depends on a variety of elements, including the complexity of the application, the app’s design, the developer’s experience, and location. In general, the hourly rate might range from as little as $18 to $150 on average. However, there’s still a catch: React Native developers’ hourly wages differ significantly from place to place. Be prepared to pay more if you opt to employ from a country with high living standards, like the USA or Australia.

Consequently, if you live in one of these nations, it would be wise to think about outsourcing development to countries with less expensive labor costs.

Here’s a table explaining the range of costs of hiring RN developers per hour in different countries:

Region                        Cost
