Want to make your web application scalable, and better organized?
This article is all about the React best practices which we should follow to build a better web application. Because good code is not only that works according to your business logic it is something that is:
Let’s understand in detail React.js and the best practices for React web application development.
Popular organizations including Meta Inc, Instagram, Netflix, Walmart, and Airbnb have built their web app frontend using React.js.
Every application keeps on growing as we add new features, integrations, and functionalities to the app. In the React.js app, you can customize the existing component or add a new component while upgrading app features.
However, if you don’t pay attention to app source code all from the beginning, you might end up with lots of spaghetti code that is difficult to manage and scale.
So, here is how you can avoid issues in code maintenance, scalability, and organization by following the best React web development practices.
Though create-react-app is the one possible way of organizing your app files, as the app started growing it became difficult to manage the source code. When there are product changes it requires a lot of work like renaming files and organizing things to keep everything in harmony with the new version.
So what can you do?
Overall, your folder structure will look something like this.
Even if you are using a UI library like Material UI, you still need customization on props, logic, and styles. A custom component library lets you reuse them across pages and even inside the other projects.
Other benefits of the custom component library:
Use state management tools, whether it is Redux or MobX. Even if your project is small you still need to manage things like authentication, and alerts that need to be managed globally. It is helpful when you want to sync up states for several components and want to use props and callback functions.
Moreover, state management works like a controller between the UI and the database. The state and actions in the layer can be used across many components.
Tracking the waiting status for the asynchronous calls on conditional component rendering can save you from unnecessary errors.
The constructor is called only once when the component is created. So whenever you make the changes to the props the component state will remain the same and won’t be updated. Therefore using props in the initial state is a bad practice.
You can fix this issue using React lifecycle method componentDidUpdate. The method allows you to update components when the prop changes. However, the method can’t be invoked on the initial render so make sure to initialize the component state with the necessary values. Not only that, use methods to update those values.
React.js works on reusable components. So try to keep your React UI components smaller, they are easy to read, reuse and maintain. One component in React should be responsible for only one functionality (single responsibility principle).
In this case, your component seems to be getting more extensive than expected. Try to split it into small components through code refactoring.
In the project, you need to handle both unified styles and individual styles. If you have your app design ready, try to define styles in the global theme. You can also use theme providers to easily customize palettes.
For styling React components, first, include them in the custom component library. And if the style is specific to a particular component, include them in the style file under that component.
In the article, we have discussed React.js best practices for building scalable applications. Following these practices will help you to overcome common issues that may arrive in web application development.
