In this post, we go through a tutorial on how to create a React application that can perform CRUD functions and take in data from a RESTful API.

Recently we have experienced rapid growth of mobile, Internet-based communication. We have smartphones, tablets, netbooks, and other connected devices that create a need to serve appropriate content for each specific front-end profile. Also, the Internet is becoming available for new regions and social groups, constantly increasing web traffic. On the other side, users' computers and browsers, and JavaScript itself are getting more and more powerful, providing more possibilities for processing data on the web via the client-side. In this situation, the best solution can often be to send data as the response, instead of sending page content. That is, we don't need to reload the whole page on each request, but send back the corresponding data and let the client (front-end stuff) process the data.

We can develop a backend application exposing a remote API (usually based on the REST protocol) and a front-end (usually JavaScript) application, which communicates with the API and renders all the data on the device.

If backend data is consumed by humans, we need to develop a user interface (UI) to provide the possibility for users to manage the data. Modern web applications should have responsive and friendly UIs, ensuring adequate user experience. Also, modern UIs can be arbitrarily complex, with multi-panel, nested layouts, paging, progress bars, etc. In this case, the component model can be the right solution. React.js is a light-weight JavaScript framework, which is oriented toward the creation of component-based web UIs. React doesn't provide any means for communicating with the backend, but we can use any communication library from inside React components.

Before starting development, we need to set up a React.js development environment.
