ReactJS for IoT Applications – Its Key Benefits, Drawbacks, & Future

If you’re involved in web development, then you may have heard about the ReactJS framework and the Internet of Things (IoT) technology. With the rising popularity of IoT devices, IoT app development is transforming the way we communicate with smart homes, smart cities, and smart factories. ReactJS is an open-source, front-end JavaScript framework that is being widely used for building IoT applications. But why should you choose ReactJS for IoT applications? What are its benefits, drawbacks, and future? We are going to discuss everything in detail in this blog. So, let’s begin!

Why Choose ReactJS for IoT Applications?

The features and benefits that ReactJS offers make it a suitable platform for building IoT applications. Let’s take a look at the features and benefits of ReactJS for IoT app development.

  1. Easy to Maintain Apps

Using React, you can build easy-to-maintain apps and make changes if required. React’s flexibility allows you to scale your app without any hassle. Hence, you can cut down on costs and development time.

  1. Smooth Transition to React Native

React developers can easily shift from ReactJS to React Native for building mobile applications with a native-like quality, look and feel.

  1. Active Community

ReactJS library is managed by numerous contributors across the globe. The support received from the vast and active community ensures that the library is up-to-date.

  1. Efficient App Development

React helps developers to write code only once and use it on multiple platforms. This reduces the development cost and time. A shorter development timeframe ensures superior and clean code elements. Also, the code reusability feature of ReactJS upgrades the developer’s capacity to develop applications.

  1. SEO-friendly

SEO-friendly sites rank higher on search engines like Google. If you want to build SEO-friendly websites, then you should hire ReactJS developers for your project.

ReactJS provides high speed that ensures higher performance and a smooth user experience.

  1. Facilitates Smooth Process of Code Writing

The ReactJS library uses JSX, a feature offered by JavaScript, and ensures easy composition of segments.

There are certain rules you need to follow when composing on React to create elements. This will help you ensure the source code is comfortable, clean, and readable.

JSX allows you to create applications of high-volume and customized parts, reducing errors that may occur in the bigger tree. This enables the IoT projects in shifting from HTML mockups to the react element tree.

  1. Enhances Productivity

Walmart is one of the striking examples of showing improved productivity after the use of ReactJS for IoT applications.

While the brand has several branches and subsidiaries, with their own digital presence, most of the elements remain constant.

Since ReactJS is a component-based model, it ensures increased productivity. It allows IoT app development to utilize code elements for better management of different versions.

  1. Faster Rendering

React comes with Virtual DOM that can do wonders for IoT applications. The Virtual Dom shows progressions in the record object model. This model helps in figuring out some critical DOM activities that enhance the client’s experience while resulting in higher app execution.

  1. Code Stability

ReactJS adheres to a downward stream of information which helps in maintaining the overall structure even in any change arises.

After this, it requires developers or designers to make adjustments to the state and continue making the amendments. Then, only select segments will be refreshed.

This type of structure makes sure that the IoT projects limit the information that offers robust source code and its consistent execution.

  1. Compositional Structure

React is based on a compositional structure. This type of structure facilitates the writing of code in a well-organized manner. IoT leverages older models that were huge and quite complicated to manage.

The composition model provided by ReactJS for IoT applications could simplify the app development process.

  1. Separation of Concerns

React treats each of its components as an individual component. So, you can work on each of the components separately.

This ensures that the other components are not affected if there is malfunction occurs in anyone. React achieves the isolation of processing and receiving data in the components using components.

Data transfer is done through props that are usually objects containing component-related information.

This feature of React is useful when it comes to handling parent and child components. Separation of concerns by ReactJS for IoT applications is beneficial when the apps are based on components. It simplifies the passing and receiving of props by creating two unique components.

  1. Lifecycle Method

The ReactJS library is based on components and ensures all the components are executed into a Virtual DOM irrespective of the execution.

The lifecycle method present in the ReactJS library makes sure that the developed components can handle continuous changes. These changes are essential for seamless interactions of the web and mobile apps for users in real life.

Three methods are primarily used to ensure the lifecycle method is followed. They are:

  1. initialization for mounting
  2. updation for providing updates
  3. destruction for unmounting.


  1. Open and Rich Set of Tools

Another benefit of React is that it offers the best platform for front-end development. The ReactJS library is free to use and operative. Moreover, it provides a rich set of tools that come in handy on several occasions.

  1. Perfect for Mobile Apps

ReactJS libraries include real-time reloading as well as portability, flexible architecture, and reusable components. These features are useful in developing IoT-powered mobile apps.

Drawbacks of Using ReactJS for IoT Applications

Using ReactJS for IoT applications comes with a few drawbacks. Some of the common disadvantages include:

  1. Open-sourced Library

ReactJS is an open-source and free-to-use JavaScript library. Therefore, there is no proper support, and the introduction of newer libraries results in the creation of collision, which further leads to unpredictable app behavior. Therefore, a ReactJS development company cannot completely rely on ReactJS for IoT applications to meet industrial needs.

  1. UI-focused

React focuses on the UI and front-end development for applications. It offers negligible flexibility for IoT and Industrial IoT applications and offers a limited increase in productivity. However, the library relies on other libraries to achieve the best outcomes.

  1. Has Not Become Mainstream for IoT

ReactJS has not become mainstream for IoT projects. Hence, using ReactJS for IoT applications can bring in many challenges. While specific libraries can assist integration, it is still a challenging task for a ReactJS development company at the end of the day.

The Future of ReactJS for IoT Applications

Using ReactJS for IoT applications offers the following benefits:

  1. Code Readability

Since React is component-based, it is easy to understand and figure out.

  1. Quick App Development

React can be easily modified and used and reused frequently.

  1. Updated in Real-time

You can create updates effortlessly because of the way React’s components are rendered.

  1. Greater Sustainability

Since all React components are separated parts of code, identifying and fixing issues becomes much easier.

Wrapping Up

So, these are some of the benefits and drawbacks of using ReactJS for IoT applications. Practically, React is suitable for small-scale IoT projects. It is not an ideal tool for building industrial IoT applications. It’s because React is designed for front-end development and UI-focused applications. It is not mainstream for IoT projects.

IoT app development using React could create problems for developers. So, to conclude, you may hire ReactJS developers for building smaller IoT projects and not for complicated ones.
