How to use react native text input? Handling text input in React Native can be a tricky task, especially for beginners. However, with a little bit of knowledge and practice, it becomes a breeze. In this blog, we will cover everything from basic to advanced techniques for handling text input in React Native. First, let's start with the basics. In React Native, the most commonly used component for handling text input is the  TextInput  component. This component allows the user to enter and edit text. It has a wide range of props that can be used to customize its behavior and appearance. Some of the most commonly used props include: value : The current value of the text input. onChangeText : A function that is called when the text input's value changes. placeholder : The text to be displayed when the input is empty. secureTextEntry : A boolean value that determines whether the text input should hide the entered text (e.g. for passwords). Here's an example of a basic text input...

Understanding State and Props in React Native Functional Components React Native, the popular framework for building mobile applications, allows developers to build both functional and class-based components. In this blog, we will be discussing the concepts of state and props in functional components. States in React Native refers to the data or variables that determine a component's behavior and render dynamic content. It is an object that holds the current values of a component and can be updated by the component itself. The state is managed by the component and can be accessed and updated using the  useState  hook. const [name, setName] = useState("test user") In the example above, we are using the  useState  hook to create a state variable called  name  with an initial value of "test user". The hook returns an array with two elements - the current state value and a function to update the state value. In this case, we are destructuring the array to two v...

Exploring the Power of Custom Hooks in React/React Native Developers are constantly looking for ways to enhance the performance and functionality of their apps as the popularity of React Native continues to rise. Using custom hooks is a powerful tool that can help with this. Utilizing custom hooks, component logic can be converted into reusable functions. They keep your code organized and simple to maintain, allowing you to share logic across multiple components. By allowing you to only re-render the specific parts of your components that require updating, custom hooks can also improve performance. You must first write a function that begins with the word "use" in order to create a custom hook. After that, this function can manipulate state and props, call other hooks, and return a particular value or piece of functionality. You could, for instance, make a useFetch hook that gets data from an API and changes your component's state. When using custom hooks, one of the best...

5 Tips to Optimize React Native Performance React Native has become one of the most popular frameworks for building mobile apps, thanks to its ability to create high-performing and responsive apps that run smoothly on both iOS and Android. However, as apps grow in complexity and features, it becomes increasingly important to optimize performance to ensure a great user experience. In this blog post, we’ll cover 5 advanced techniques for optimizing React Native performance. Code splitting: One of the most effective ways to optimize performance is by code splitting. This technique allows you to divide your codebase into smaller, more manageable chunks that can be loaded on demand. This not only speeds up initial load times, but also reduces the overall size of your app. Lazy loading: Another technique that can help improve performance is lazy loading. This approach delays loading certain components or modules until they are actually needed, which can significantly reduce the amount of tim...

Mastering the art of state management in React Native React Native is a powerful framework that allows developers to build high-performance mobile apps using JavaScript.

However, managing state can also be one of the most challenging aspects of working with React Native. There are various ways to manage state in React Native, but the most popular and recommended approach is to use the setState() method, which allows you to update the state of a component and re-render it. Another popular approach is to use state management libraries like Redux or MobX, which provide a centralized store for your app’s data and actions. One of the best practices for managing state in React Native is to keep your s...

In React, a custom hook is a JavaScript function that starts with the word “use” and that can call other hooks. Custom hooks allow you to extract component logic into reusable functions. To create a custom hook, you can define a function that starts with the word “use” and that includes any logic that you want to reuse. You can then call this function within your components to access the logic it contains. Here is an example of a simple custom hook that manages the state of a toggle button: This custom hook uses the built-in  useState  hook to manage a piece of state that represents whether the toggle button is on or off. It also defines a function called  toggle  that can be used to toggle the state. The hook returns an array that contains the current state and the toggle function. Then you can use this custom hook in your component: In this example, the  MyToggleButton  component calls the  useToggle  custom hook and destructures the returned ar...

Webpack is a JavaScript module bundler. It is a tool that takes all of the different JavaScript files and other assets that make up a web application, and it generates a single bundle that can be included on a webpage to load the entire application. In a React application, Webpack is often used to bundle together the JavaScript files that make up the application, as well as any other assets such as CSS, images, and fonts. This allows you to write your application using a variety of different modules and dependencies, and then use Webpack to generate a single bundle that can be loaded by the browser. Webpack also allows you to use a variety of different loaders and plugins to process and optimize your assets before they are included in the bundle. For example, you might use a loader to transpile your JavaScript from newer syntax to an older version that is compatible with more browsers, or a plugin to minify your CSS and JavaScript to reduce the size of the bundle. Webpack is often used...
