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.

    Existing React + Flask application - Make call to a rest api in async/await style - Properly use "auth" when calling separate rest api. - Make application to be startable on a Linux OS via bash script ( I can help, but I don't know how to do the "webpack" stuff) - You will work with code from an existing Flask + React Single Page Application so you won't be working from scratch. There is a backend API that intelligently indexes a pdf. The backend API returns an index that is consumed by the frontend to provide an enhanced user experience reading the pdf. The api call to create the index takes minutes to perform. Therefore we need async/await style api call. Please see the attached to get an idea of what the user experience is like.
