Web app development with React.js

React.js makes it painless to create interactive User Interfaces. You can design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.

Build scalable components with React.js - use them to make complex interfaces.

React.js is an open-source JavaScript library which is used for building user interfaces specifically for single page web applications. It aims primarily to provide speed, simplicity, and scalability. With React.js you'll be able to achieve mobile-app like user experiences on the web.

React.js is maintained by Facebook, Instagram and a community of individual developers and corporations. It is all about components - basically custom HTML elements - with which you can quickly build amazing and powerful web apps. It can be used in the development of single-page applications and mobile applications.

You can use components for building highly interactive user interfaces. It abstracts various typical elements modern UI’s tend to have (SaaS web applications), packing them into reusable, independent pieces – a fact that makes React-based apps highly scalable.

You just need to build a component once, configure it to your needs, dynamically pass data into it (or listen to your own events!) and re-use it as often as needed. Declarative views make your code more predictable and easier to debug.

React.js plays really well with the most famous state management libraries out there such as Redux, Flux and MobX. Once again developers are free to choose the right tool for the right job and build a responsive user interface that can scale really well without writing volumes of spaghetti code.

React has become the most preferred choice when it comes to writing client side web applications.

React.js is definitely the most popular JavaScript framework these days. It’s used to create web applications that are fast, modular and everything can be done with just Javascript.

You can use components for building highly interactive user interfaces. It abstracts various typical elements modern UI’s tend to have (common in SaaS web applications), packing them into reusable, independent pieces – a fact that makes React-based apps highly scalable.

The component life cycle lets you know when a component is created or destroyed and perform any actions if required.

React.js web app development for Pros. Built by pros.

More than 90% of our projects starts from referrals by satisfied clients.

Our validated MVP needed intensive improvements to its UX and design. We decided to use React.js and they started work before we even signed the papers. We became members of the team from the beginning, sharing their chats, work, and task management tools. We recently decided to hire United Ideas as a software development provider for another project; we look forward to working with them again.

United Ideas built our web app using React.js. Their ability to deliver sprints stands out. We received the first version after a few months and quickly saw users and revenue start coming in. I would recommend them to anyone considering a similar project. Their developers worked through the night several times, and I appreciate that commitment.

We were highly satisfied with their work and engaged them for more projects after this app was completed. United Ideas tackled nearly every project we could throw at them. They were also upfront about anticipated costs and potential challenges and issues that might arise in the project, which I appreciated.
