React.js is an efficient, declarative, and flexible open-source JavaScript library that is useful for developing user interfaces specially for single page apps. With React.js, users can build complex user interfaces from “components.” Components are small and isolated pieces of code.

React.js can also be used as a base in the building of both mobile and single-page apps. Although, complex React.js apps usually require additional libraries for interaction, routing, and state management with an API (Application programming interface).

React.js makes it possible for developers to design large web apps which can change data, without reloading the page.

    I am a full-stack developer, but have hit a few bumps and need some help to get everything situated. We have an app that currently works, but since I have redone the front end (React) I have had issues connecting to the Rails library my colleague created. He incorporated a lot of security protocols which is great, once people are actually using the app. Ultimately, we have decided to recreate the rails backend on my front end project.

Then, after we have the rails re-done in the new folder, we need to use Redux to connect the database to the front end. I have some experience with Redux, but would prefer to have someone who can help me get a solid game plan and allow me to do most o...
