From the project’s readme file:
I am sharing here a “GoToTop” React JS component that I created today. This component will render a button (shaped as an arrow) when the user scrolls down, past a certain point. When clicked, this button will execute a handleGoToTop() function that will smoothly scroll the screen back to the top.
This is a styled component, making it very portable. It also uses React hooks and TypeScript.
Among the several strategies aimed at increasing the productivity of a development team, the proper organization of the code related to the software being conceived undoubtedly occupies a preponderant place. Over the years, several methods and tools have been created for this purpose. It is important to know them, especially since they can very concretely result in a substantial saving of time, at least in terms of maintenance activities and bug fixing.
In this context, we’ll take a look at how to deploy styled components in a React JS project with TypeScript using the styled-components library. This technique allows components to contain their own styles. This “encapsulation” of styles also involves CSS in JS, using tagged template literals.
By default, browsers will block certain requests if both the client and the server are not in the same origin. Cross-origin resource sharing (CORS) is a specification designed to allow restricted resources from a remote server in a given origin, to be requested by a client associated to a different origin. An origin, as defined by the RFC6454, implies “identical schemes, hosts and ports”.
Usually the request from the browser will be accompanied by its corresponding HTTP headers, including the request’s origin. Example of the HTTP headers on the request:
