Guide to Build & Organize the Architecture of Large React App in 2021
In this post, we are going to discuss the basics of React, steps to build and organize the architecture of a Large React App in 2021.
What is React Native App Development?
React Native is an open source framework used for mobile application development and it was introduced by Facebook. When you think about making a choice for development, entrepreneurs and start-up owners do have an affinity for React Native. There are a lot of noted brands who already use this framework and have never faced any issue. Various tech leaders like Skype, Facebook, Tesla, Bloomberg etc have opted for React Native for Android and iOS platforms. Another advantage is that react native app development is cost-effective and is perfect for a user to get access to the particular app. It enables you to manage and build hybrid mobile app development in an insightful way.
Why is React useful for App Development for Variety of platforms?
Listed below are the top reasons to choose React for App Development.
1. Cost-Effective -
When you are just starting a business, money is tight and you would want to spend it wisely as there are lots of activities to be taken care of. Every start-up or small business is looking to achieve swift returns to withstand a tech-savvy market. It is crucial to build faster and stay longer. The main reason to Hire React Native Developers is to save crucial time and money when choosing React Native for mobile app development.
2. Cross-Platform App Development -
3. Less Memory Requirement -
React is adaptable with various third party libraries and plugins and React native tools to offer a smooth run-time. The valuable framework along with diverse modules, the third party inclusion is made easy. It is easy to connect the module to the plugin via native module without using WebView. This phase is simply linked with the application features that enable it to provide a rapid response. In doing that, React native uses minimal memory space as cross-bridge linking is not necessary and most of the code is used during run-time.
4. Sustainable App Development -
React native is still growing and looking at the popularity of the platform, it is safe to say that is here to say. It is difficult for any developer to resist this exceptional user-friendly format and all-inclusive framework. It has almost covered the market of app development in no time. Facebook will ensure that it stays longer. With each passing day, the framework will keep getting better and offer new solutions. There is no need to learn different languages and make complex codes when you can easily build any application with the help of React native.
5. Complex Tasks using Simple Codes -
React Native app development enables you to execute complex tasks using simple codes. The framework makes use of the UI library developed by Facebook to build straightforward codes for adopting and executing ReactJS. Interestingly, React Native mobile apps have a “Live Reload” feature. It enables us to operate on real-time code updates and make changes while the application is loading.
Components Used to Build a React Mobile Application -
To begin any app development project, it is imperative to build a project that you have already generated using the CLI tool. Then the next step is to collect the components to develop an application. These components will be the building blocks or visual elements of your React Native app. By choosing react best practices, you can definitely get past this step but we have mostly covered the main components that should be used.
- Core components like text, images, ScrollView, TextInput and StyleSheet.
- Components used for listing the products like Flatlist and SectionList.
- UI components that add features to your application are Picker, Slider, Button, Switch etc.
- Android specific components like ToastAndroid, ViewPagerAndroid, TimePickerAndroid, DatePickerAndroid etc. iOS components like ActionSheetiOS, SegmentedControliOS, AlertiOS, PushNotificationsiOS etc. Various other components like CameraRoll, Dimensions, Clipboard, Keyboard, Linking and more.
- Apart from that, there are multiple components and APIs available in React native that you can safely choose from the documentation as and when required.
Best Practices to Organize Large React Apps in 2021We will discuss the best practices to build and organize Large React apps in 2021.
1. Develop Tools and Linting -
We are a huge fan of webpack for building our internal projects. Accepting the fact that it is a complicated tool to use at first, the team has put in great efforts in version 5 and the new documentation helps ease the process too. As you get the webpack and have the concepts in your head, you will have great power to work on React apps. The ES modules first launched ES2015 to export and import certain dependencies. The syntax has been there for quite some time now and it can support CommonJS too. Moreover, webpack can get rid of dead code from bundles using ES2015 modules which is a great feature to have in your armour. A majority of the web ecosystem has moved to ES modules, hence this is a common choice for our upcoming projects.
2. React Components -
Once there is a SRC folder, the difficult part is determining how to structure the components. Earlier, the developers used to gather all components in a single large folder like SRC. components but we figured out that it gets tricky on large projects soon. It is ideal to include folders like “smart” and “dumb” components which are also known as “container” and “presentational” components. We have sorted components depending on the areas of the application where it is used with a core folder for common components that can be reused and are generic in nature. By categorizing in folders, you can avoid prefixing components with the area of the application they are used for.
3. Eliminate Large Render Methods -
This particular factor used to refer to the render method defined on React class components, it is still valid when discussing functional components where you should take care of component rendering a large piece of HTML. The idea is to have multiple small React components instead of a few large components. The best way to know this is the size of the render function. You would want to include the number of props or items in state as a good indicator. If a component is including several props, it might be a sign that it is doing a lot.
4. Tests -
It is important to test extensively and we have realized that Facebook’s Jest framework works best for testing. It is easy to work with, quite reliable and swift in terms of handling a large number of tests along with providing quick feedback. In the past, developers used to have a dedicated tests folder for all the tests. So, if the application got bigger, it would be difficult to find the right files and if you shift files in src, you can lose track of it. Moreover, if there is a file in tests that needs to import the file in src, you will have longer imports.
There are various ways to execute a task and the same is true of React. One of the most popular features of React is how it allows you to make optimum use of tooling decisions, develop tools and folder structures and it is high time that it gets the due recognition. We hope this post has given you an indication of approaching large React apps but we would always advise you to tweak and use it according to your business needs.
