In a composable architecture, the system is built from smaller, reusable components that can be combined to create larger systems. The key benefit of composability is that it allows developers to build increasingly complex systems out of smaller, simpler pieces. This improves code reuse and modularity while making it easier to test individual components and services. In this article, you’ll look at how the composable architecture works and why it’s helpful for developers.
Reusing Screen Feature
Reusing screen features is an excellent way to reduce the amount of code you have to write in your application. To reuse a screen feature, you include it in your project as a reusable component. A reusable component is just like any other type of Visual C# class or structure; it can contain properties and methods. The only difference is that the Visual Studio IDE automatically creates an entry for each reusable component in your bin\Debug folder when you compile your project.
The idea behind this approach is that by always keeping track of which each feature uses classes and namespaces, you can easily use these libraries again in future projects without having to specify them manually every time.
Reusing Business Logic
One of the biggest advantages of composing your system is that you can reuse business logic between multiple screens.
If you have an application with multiple screens, each screen will have some common logic to it. For example, when a user clicks on the add button in a shopping cart application, a new item will be added to their cart. In this situation, if you write that code once and use composition, you do not have to write it twice; instead, compose it so that one click adds an item to the next screen. For example, suppose there are many similar scenarios in your system. In that case, using composition will result in less coding being done by reducing duplication and improving performance because no extra functionality has been added.
React Native Navigation
React Native Navigation is a library that allows you to use a navigation drawer, tabs, side menu, or any other view controller presentation pattern in React Native. It’s based on the top open-source libraries for navigation and uses React Native Elements to make it easy to create your own custom navigators.
React Native Navigation makes it easy to add and manage multiple screens in your application by providing a single API for navigation. However, if you want two different ways of switching between views (such as through buttons or gestures), you can do so without having to learn new APIs for each one!
Reusable State Management
The two most popular state management libraries in React Native are Redux and MobX. Redux is by far the more powerful library, but it’s also more difficult to learn and use. With MobX, you can start your first app quickly, but you’ll hit limitations as soon as your application grows beyond a certain size.
“With a composable architecture, if a vendor’s product fails to meet your needs, you’re free to look elsewhere,” says Uniform experts.
Using Composable Architecture lets you take advantage of both Redux and MobX for different application parts. You’ll use Redux for managing high-level state data like authentication tokens and global error messages while using MobX for a local component state that doesn’t need to be shared with other components or used from anywhere else in the app.
