FAQ
What types of apps can you build with React.js?
As an open-source JavaScript library for creating dynamic user interfaces, React.js makes it possible to build interactive web and mobile applications, such as ecommerce platforms, SaaS solutions, real-time chat apps, healthcare portals, and social networks. React.js powers many globally known applications, including Meta, Netflix, Instagram, WhatsApp, and Skype.
Why use React.js in a frontend development project?
There are several reasons why companies should consider React.js for web application development, such as:
- Reduced development time
due to the creation of reusable components, the use of JSX (a JavaScript syntax extension), and the availability of a rich ecosystem of React tools and frameworks - Flexibility
achieved thanks to React’s component-based architecture, syntax, and compatibility with other technologies - Excellent app performance
ensured by React’s virtual DOM, which speeds up interface updates - Ability to create SEO-friendly applications
through server-side rendering and optimized app performance
When do companies need React development services?
Companies can benefit from hiring a React.js development company to assist with their projects when they:
- Have React.js skill gaps or need React.js developers with specialized skills (e.g., full-stack JavaScript developers)
- Need to speed up the development process to meet the project’s tight deadlines
- Prefer to outsource the entire React.js development project to focus on other business activities
How long does it take to develop a React.js web application?
The development time for a React.js web app can vary based on the app's complexity, the development team’s experience and size, and other factors.
Building a basic React.js application usually takes 6-12 weeks, while the development period can extend up to six months in case of large applications with complex functionality and multiple integrations.
Does React have any limitations?
Although React offers multiple advantages for web and mobile app projects, developers highlight the following limitations that companies should be aware of:
- React’s minimalistic design that doesn't enforce how projects should be organized, therefore solid project management expertise is required
- A steep learning curve
- Frequent library updates that require constant learning and adaptation
- Complex documentation
What are the key factors to consider when choosing a React.js web development company?
To start, get to know the potential service provider’s experience with the technology and what React.js-specific expertise they possess.
Then, explore their completed React.js projects, especially those relevant to your industry and use case. The more extensive their portfolio is, the better the provider will understand your specific needs and deliver an optimal solution.
Aspects such as adherence to globally recognized software security and quality standards and utilization of diverse project management methods indicate that the provider can deliver high-quality apps within time and budget limits.
Additionally, you can research popular online platforms for client reviews to help you decide.
