ReactJS is one of the most popular JavaScript frameworks. Over 40% of developers worldwide rely on the framework to build amazing apps. They are a pleasure to use and provide an excellent user experience for higher engagement.
However, you still have room to write better ReactJS code or improve its reliability. So, here are a few proven tips and tricks to write cleaner and more efficient ReactJS code.
Switch To React Query From Redux
Managing the state of app components becomes a challenge as your product grows. So, developers rely on state management libraries such as Redux to manage app states.
Additionally, Redux facilitates the update of the application’s state by synchronizing the server state if your app uses data via an API.
The process often becomes difficult as developers have to:
- Fetch data
- Manage various app states
- Deal with load, error, and data states
React Query can come in handy in such situations to provide more control over the process of creating HTTP requests. In addition, React Query can rely on useful bindings to fetch data in your apps.
Moreover, it allows developers to manage app states easily throughout app components. Best of all, you don’t need to update the app state manually.
As a result, React Query is a better choice to manage different aspects when you deal with data. It automates the process of managing instances relying on functions generated by the useQuery.
Leverage The UseReducer Hook Early On
useState hooks are commonly used in React apps as components that deal with numerous states. As a result, your app may be overcrowded with too many useState hooks. It also signifies your app is growing in size and complexity.
Many developers create sub-components to dump a few states and JSX. It allows them to clean some states and JSX simultaneously. However, this is not always possible, and programmers transfer several states within a component.
Here, developers may take advantage of the useReducer hook to improve component legibility. You will find its mention in the React docs to help manage several sub-values and complex state logic.
The useReducer hook makes your component cleaner and reduces useState hooks. Therefore, try to utilize the useReducer hook from the early stages of coding.
Rely On Custom Hooks To Simplify React Context
Developers use React Context to make data flow through component trees. The process makes it possible to send data to chosen components instead of relying on properties. Also, useContext is used to manage the React Function component’s context.
However, the process is not always the best for all scenarios. Developers may want to use the data sent in the context of a chosen component. So, they must import the context object they generated and React for fetching the usage.
In such scenarios, custom React hooks can simplify the process. They can eliminate the need for creating numerous import statements, resulting in cleaner ReactJS code.
The Managing States That Rely On The Prior States
Developers often find it challenging to manage states across the app. The challenge may increase in intensity when one state is dependent on the earlier state. The server-side techniques programmers use may not always produce desired results.
The best way to get past the problem is to set your status as functions whenever your next state depends on the earlier one.
Additionally, developers may batch React state updates combinedly to make ReactJS code cleaner. It also increases the reliability of your code and makes different states work flawlessly.
Make The Most Of Context Providers
Developers use numerous Context Providers for React apps that may grow overwhelming over time. However, context providers don’t just facilitate the fetching of React context. They also fetch context from third-party libraries so that your tools may not lose access to app components.
With time, the whole thing can turn too difficult to manage. However, there is a simple way to deal with the issue.
Don’t put all your context providers in a single index.js or App.js file. Instead, you can rely on components like Context Providers to serve your purpose.
This makes the whole of your code less messy and more reliable.
Use Error Logging Systems
React developers need to log errors in order to improve app performance and code reliability. They can depend on console.log to log errors in the development stage. It allows them to access all errors from one place to save time and increase convenience.
However, the console.log technique is not adequate anymore as you deploy your app into production. The reason is that you can access the error logs only within the users’ browsers, which beats the purpose.
You need something like console.log to view all the errors from one source. That will allow developers to resolve the errors quickly and keep your app performing as desired.
In such cases, you may rely on third-party error logging systems to log all errors in one place. It will go a long way to help you improve the reliability of your code.
Final Thoughts
Coding in React is a good way to build an app that performs like a champion. Still, you need to write clean code and improve its quality to gain a competitive edge in the market.
You can use the tips and tricks we revealed, like switching to React Query from Redux. It is also possible to make your ReactJS code reliable by relying on custom hooks.
