7 Pitfalls of React Hooks You Should Avoid

Hooks in ReactJs were introduced in October 2018 as a function in JavaScript only to allow the use of React without using classes. So developers can use stateful functional components without worrying about storing the class instance as a preferential state. Now with ease in operations, the use of React Hooks has rapidly increased as they simplify the management of land and thus have no side effects in the application.

In React JS Web App Development, many default hooks are available, whereas custom hooks are also developed to reuse stateful behavior in the different components. Although React hooks became quite popular with developers, still many pitfalls emerged, causing unnecessary delays. If React Hooks are not used precisely to their life cycles, side effects, and state, then you are sure to find the pitfalls. Here are the seven main pitfalls of Reach Hooks that one should avoid getting the desired result and their subsequent solutions.

Not having a good foundation

One of the first things developers often ignore is to read the documentation carefully and start using them only to see the results with issues. A good foundation is a must, to begin with. It is recommended to spend some time going through the React official Hooks documentation and FAQ sections. For any beginners who are preparing to learn React JS development on hooks, this has to be the first step to have a good foundation.

Not using the ESLint Plugin

Around the same time hooks were released, ESLint, the official plugin by React Time, was released simultaneously, governing the rules of the hooks subsequently. This plugin has two specific practices: ‘rules of hooks’ and ‘exhaustive deps.’ These rules, by default, come with a recommended configuration that sets ‘rules of Hooks’ to an error and ‘exhaustive deps’ to a subsequent warning. These rules are enforced automatically by this plugin. One needs to install the ESLint plugin, use and follow the rules set precisely to catch real bugs inside the code, and simultaneously understand using the hooks in the process.

Overthinking Performance

In case you think code is quite complex to provide users with great features and performance is going to be a significant worry. React JS optimizes itself and offers a higher performance by making the whole process smooth. Unnecessary re-renders needs to be fixed to avoid them being slow and not for production. React JS is quite fast and proficient by default, so rather than going for any premature optimizations, complete the code and then use the optimizations for better results. More often, we see a production version of React working faster in the development state.

Testing of React Hooks

Developers also overthink about testing the hooks with their integration on all their components. As the end-user wants the results and doesn’t care about whether you used hooks or classes. So if tests are rendered on the screen, then it most probably your code works. So one can avoid testing implementations in some cases and work on the end-user itself. Officially they recommend that Hooks will be the primary way for developers to write Reach components; still, you don’t need to rewrite existing classes to Hooks unless you plan to restructure the whole app code.

Thinking in life cycles

In React Hooks, the components are declarative that allows the code to work at specific relations to the state change rather than the life cycles. Although it creates a few confusion for beginners still once you experience and use it, this will cause fewer bugs in your code. On the other hand, it works naturally in avoiding bugs in the system, for instance, when you forget to handle a state update, etc.

Monitoring Reach Hooks

In case one is worried about the working of the react hooks, they can do by monitoring them in the production stage. Here you can see how users are interacting with the code and desires results. This can be arranged by using specific components like LogRocket, where you can monitor the user experience for free, to begin with.

Conclusion:

React Hook plays a significant role in the development process in bringing the right performance. More often than not, developers get stuck with these pitfalls for overthinking, performance, and not having a great foundation. But with proper application, these hooks can be precisely used for better performance. Developers must avoid these pitfalls to get the best results from their coding.
