React Native Boilerplate

Project Structure

Scalability and code management are made easier by a well-organized project structure. A common structure could have the following folders:

• src/: Contains all the source code of the application.
• components/: Reusable UI components.
• screens/: Screens or views of the application.
• navigation/: Navigation setup using React Navigation.
• redux/: Redux-related files (actions, reducers, store).
• services/: Utility functions, API services, etc.
• assets/: Images, fonts, and other static assets.
• utils/: Helper functions and utility modules.

React Navigation

A boilerplate typically includes a basic navigation setup using React Navigation. This may involve creating a NavigationContainer and defining stacks, tabs, or drawers.

• Tab Navigation

  Users may effortlessly navigate between numerous screens by using tab navigation, which arranges them as tabs at the top or bottom of the screen.

• Stack Navigation

  A hierarchical navigation architecture where screens are pushed and popped from a stack is made possible by stack navigation. This is helpful in situations where you need to implement a navigation flow or navigate through a number of pages.

• Drawer Navigation

  A slide-in menu is available from the side of the screen with drawer navigation, and it is usually used to provide settings or navigation options.

• Nested Navigators

  You may integrate various navigation patterns within your app with React Navigation's support for nested navigators.

React Hooks

Introduced in React 16.8, React hooks are a powerful feature that gives functional components access to state and lifecycle capabilities that were previously exclusive to class components. You can access state and other capabilities without developing a class by using hooks. They offer a clearer, more concise method for handling side effects and state in React components.

Some widely used React Hooks are:

• useState
• useEffect
• useContext
• useReducer
• useCallback and useMemo

NativeBase

NativeBase is a component library designed for ease of use and functionality by Geeky Ants. It gives developers a set of reusable and adaptable Material Design-compliant UI components that let them quickly create stunning and responsive mobile interfaces. It facilitates the creation of unified user interfaces for Android, iOS, and the web. Developers can create universal design systems with it. It's one of the tools that provides a native application development ecosystem locally. Cross-platform UI components can be created by developers using React components and third-party libraries.

Key Features of React NativeBase:
