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've got a javascript running on some Linux servers. To run the script, I SSH to the server, manually change the contents in a file and run "node ". The script will fetch the objects from the file, then give me multiple options and I input the number that represents each option to run the script accordingly, and the script will display its results. I want to build a website with an authentication system, so the users can register and log in, change the contents of the file via the web interface based on my requested layout, run the script on the remote server, select options to interact with the script, and then see the results on the web. Let me know your proposal, the time to complete the project and the total cost. Thanks.
