This application is built over create-react-app.
App Component (functional)
First, App component renders the Main Component, then Main Component renders Header, Loader, and UserCards components.
Main Component (class)
Initially, the view of the Header component is rendered on the screen. When the Get User button is clicked, the Loader component’s view, basically a spinner, is added to the virtual DOM, followed by the browser DOM until the data is fetched through API and stored as a state. Once the data is entirely fetched, the loader state is set to false, and the view of the UserCards component replaces the view in virtual DOM.
Header Component (functional)
This component renders the navbar, which contains a brand logo and a brand name, and the "Get User" button that is an onClick function.
Loader Component (functional)
I have used font-awesome animated icons to show the loader animation.
UserCards Component (functional)
The component receives API response through props and then renders the view, which is made responsive using bootstrap classes.
There is only one style file for all the components, i.e., App.css.
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
